Pulseeffects: Jamming/stuttering during playback from the Chromium

Created on 30 May 2018  ·  84Comments  ·  Source: wwmm/pulseeffects

External USB sound-card (more often) and integrated into motherboard (less often).

(UPD: Now for integrated it occurs as often as for external)

Settings (only Bass Enhancer is enabled):

Run PE in debug mode PULSEEFFECTS_DEBUG=1 pulseeffects and paste its output here. Maybe some clues are printed when the stuttering happens

Start at 17:18:25.

Strong lags at 17:18:42, 17:18:57 and 17:19:36. Just intensively switching Chromium tabs, refresh pages and start Atom Editor.

Later there can be small lags during to regular computer usage (and music listening).

It continues to lag. Without any logs sometimes.

100% scenario:

  1. Google Play Music playing in one tab
  2. Load Beatport artist page in another tab

Got 2 lags per page loading (audio object initialization?)

I see nothing wrong in the logs.

In order to save battery PulseEffects pauses its pipeline when no audio app is playing and puts it back online when an app wants to play something. But despite of the many volume meter stream creation and destruction you have in the logs there is no line about pipeline state changes. So this does not seem to be the source of the problem.

Does this happen in other browsers or only in chromium? I use chrome and at least in youtube, netflix and crunchroll I have no problems when switching tabs or doing other stuff

Does this happen in other browsers or only in chromium? I use chrome and at least in youtube, netflix and crunchroll I have no problems when switching tabs or doing other stuff

YoutTube in Chromium: the same lags for Beatport page.

Google Play Music (GPM) in Firefox: everything is OK, no lags. And no logs from PulseEffects!

GPM in Google Chrome (stable): the same lags, the same logs.

So, where are logs — there are lags, probably.

But despite of the many volume meter stream creation and destruction you have in the logs there is no line about pipeline state changes. So this does not seem to be the source of the problem.

But for what volume meter stream (pipeline?) creating at Beatport (artist) page loading and terminating when page loading is done? It's strange.

The same in the version 4, but there are no any logs in the debug mode (G_MESSAGES_DEBUG=pulseeffects pulseeffects). :disappointed:

Can you add please more debug logs? I'll attach them here when these situations occur.

In version 4 I added a lot of debug messages. I am not sure if there is much more that can be added. Could you try to provide the other info mentioned at Reporting Bugs. Maybe there is some clue there

Yeah, sure:

Distribution and Desktop Environment.

Arch Linux, GNOME Shell 3.28.2-1

PulseEffects version and how you installed it.

4.0.1-1


Oops, I realized that I have loaded modules from another equalizer:

https://wiki.archlinux.org/index.php/PulseAudio#Load_equalizer_sink_and_dbus-protocol_module

I'll try to use PulseEffects without them.

If I'll have any trouble — I'll write there remain answers.


Sorry, but I have the same troubles for Beatport page, for example. So…

sudo renice -10 -p $(pidof pulseeffects) ?

Thank you, but it didn't help too much. :(

Maybe a little.

I found that when setting Sound Preferences to use PulseEffects(apps) for all output, there's lots of distortion especially when multiple sound streams happen. (simple sound effects in GNOME/MATE desktop create great amounts of distortion and stuttering.) If you use "Audio Analog Stereo" (or your default output sink itself without PulseEffects), there is no issue. (And then, individually enable PulseEffects for something like YouTube on Chrome.). If I do this, I get the least amount of stuttering. The second that I tell the mixer to use the PulseEffects device for all output, there's lagging, stuttering, distortion, and just the unsettling feeling that doing any little thing on the computer will throw off the audio. I tried screwing around with buffer and block size in dconf, but doesn't seem to change much or just gets worse. I'm trying to get debug logs but nothing at all prints when I type the pulse effects debug command. I'm going to try and figure out why and post anything I can find.

Also, the other issue with using the PulseEffects sink in the volume mixer is that volume control doesn't work or stutters/lags like crazy when the volume is adjusted. It almost seems like there's some sort of feedback loop going on, but I can't tell exactly.

@xtknight, thank you!

After selecting "Built-in audio" it resets everything to use the default device, so you have to go back in PulseEffects and enable for each app individually. (And apparently it resets to default every time a new stream even starts in Chrome...hmm) I haven't yet experimented much beyond just using Chrome with PulseEffects, but let me know if this helps solve the stuttering issue. Then, we can figure out if it's an issue with multiple streams itself, or just an issue with having PulseEffects as the default system-wide sink in Sound Preferences.

@xtknight you should see log output when running PE as G_MESSAGES_DEBUG=pulseeffects pulseeffects

You should never select PulseEffects(apps) or PulseEffects(mic) as default output device. This will definitely cause troubles. Unfortunately there is no way for me to forbid the user to do this.

Multiple streams should not be an issue as long as you use the limiter as the first plugin in the effects chain. Other plugins may have their input saturated when there is a lot of apps playing audio.

In case you do not want to enable each app individually you can turn on the option Enable All Applications in PE settings menu.

@AlexWayfer does this fix your problem?

@wwmm: thanks for the insight. Would probably be a good idea to mention in documentation in red letters that using PulseEffects as the default device is bad. The workflow of the system wasn't clear to me at first. (apologies if I happened to miss something). I'm not sure if this was the original poster's problem, but just throwing it out there because that's what gave me similar issues.

In my case, using 'Enable all apps' with two concurrent audio streams from Chrome with the Equalizer enabled results in no discernable stuttering. Audio playback seems fluent; real happy with it. Let's hope the same holds true for the OP. The EQ saved my new headphone purchase.

Now that we finally have documentation it is a good idea to tell this there. I will try to remember to do that :-)

@wwmm I've also discovered some stuttering and jamming, as well as crackling with multiple streams. It doesn't seem to happen on one stream (or perhaps, it just happens a lot less?). I can hear one of the streams start to play a tad faster or slow down all of a sudden. I suppose that because the pulseeffects process is scheduled on the CPU like any other process, this is possible, but I wonder how pulseaudio avoids the issue. I suppose that this could be the same issue the original poster is happening. It's faint, but quite noticeable even when I try to ignore it. Interestingly, the time it takes certain streams to start also seems to be affected, but I haven't been able to measure this objectively. (After I press play on YouTube, it takes longer than I usually remember for the audio to begin actually playing.) There's nothing special printed in the logs about it, and I'm pretty sure it's just a timing-related issue.

Example case:

Turning on the Test Signals triangle wave and then starting any other stream causes a brief crackling. The crackling also sometimes happens at random times during playback. This happens even with no effects enabled.

Example case 2:

Adjust volume on the applications tab inside of PulseEffects when enabling it on that app vs. disabling it on that app. When disabled, volume control is smooth and normal, but when enabled, it sounds like the audio is chopped up and distorted, with portions of it replaying, every time the volume is adjusted. This is even with no effect filters enabled.

pulseeffects CPU usage:
app enabled(EQ filter)+continual volume control adjustment, single stream: ~44%
app enabled(EQ filter)+normal playback, single stream: ~17%
app enabled(no filters)+continual volume control adjustment, single stream: ~36%
app enabled(no filters)+normal playback, single stream: ~11%
app disabled+normal playback, single stream: ~1%

A lot of streams take around 2 seconds to start, like you see here. (20:07:30~20:07:32) Is this normal? But it's not always like this. Sometimes they start instantly, sometimes they delay for 2 seconds. I'm not sure what the pattern is.

You should never select PulseEffects(apps) or PulseEffects(mic) as default output device. This will definitely cause troubles. Unfortunately there is no way for me to forbid the user to do this.

Multiple streams should not be an issue as long as you use the limiter as the first plugin in the effects chain. Other plugins may have their input saturated when there is a lot of apps playing audio.

@AlexWayfer does this fix your problem?

My active output device is sound card, not PulseEffects.

Limiter is the first, but disabled, plugin:

Enable All Applications option is active.

@wwmm I've also discovered some stuttering and jamming, as well as crackling with multiple streams. It doesn't seem to happen on one stream (or perhaps, it just happens a lot less?).

For me it happens also when here is a single stream (screenshot above). :disappointed:

I can try to programmatically record these lags, but I don't know a good way to do this.

One of the things that make this kind of problem hard to fix is that they are not easy to describe in words. Specially to non native english speakers like me. So an audio and video recording can help @AlexWayfer.

@xtknight I believe the crackling you hear is caused by audio clipping (the input of something was saturated). I did some tests here with the test signal generator and it seems we can not protect everything with the limiter. We should take care to not saturate the null sinks used by PE (PulseEffects(apps) in this case) because they receive audio before the limiter. In the image below I have noises
screenshot from 2018-08-02 11-48-52
We can see clearly that PulseEffects(apps) is saturated. If we turn off all apps in PE we still have noises because the sound card is still saturated
screenshot from 2018-08-02 11-50-30
Now if I decrease the test signal volume so that PulseEffects(apps) is not saturated everything is fine
screenshot from 2018-08-02 11-51-07

Unfortunately the only thing that can be done in this case is reduce the volume. I can't avoid the null sink saturation from PE. This would have to be done in Pulseaudio.

The delays you see sometimes is normal. PE always checks if there is an audio app actually playing. If there is none our GStreamer pipeline is put in the null state. This is done to save power in laptops and on other machines with weak processors. There is no point in processing silence. Whenever you add a stream while there are others playing the delay will not occur because our GStreamer pipeline do not have to be restarted.

The noises that happen when change volume usually disappears when we set a lower latency in PE settings menu. Like 1000 us. I honestly don't know what happens between GStreamer and Pulseaudio under the hoods that could explain this. But I never heard sections being replayed.

I really doubt that PE logs will show anything useful for all the issues reported here. It seems to me that this problem is at a lower level. Maybe in GStreamer or in Pulseaudio. Maybe we should start to look at their logs. Pulseaudio logs can be taken with the steps in the advanced section of Reporting-Bugs. Gstreamer logs can be taken executing pulseeffects as GST_DEBUG=4 pulseeffects. Higher numbers can be used but GStreamer log can become ridiculously large above 4.

Some logs at some lags (not every) from G_MESSAGES_DEBUG=pulseeffects GST_DEBUG=4 pulseeffects:

Try to lower it to 256 and see if it makes any difference. Under flows in pulsesink usually lead to noise.

The pulse_manager: failed to move sink input 134 to PE are also odd. I never have those. This is a sign that something is not right.

Buffer is 200000, latency is 10000.

With 1024 block size there are lags too. :(

The pulse_manager: failed to move sink input 134 to PE are also odd. I never have those. This is a sign that something is not right.

https://github.com/wwmm/pulseeffects/issues/217#issuecomment-395050149

At least here I only have under flows if I set the block size too high. It is strange that they increase when you reduce the block. And if you set the buffer to 50000 with a block size of 512 or less?

And if you set the buffer to 50000 with a block size of 512 or less?

Doesn't affect.

Here there is an explanation for under flows:

GST_QOS_TYPE_UNDERFLOW: an element is receiving buffers too slowly and has to drop them because they are too late. Upstream should increase the processing rate

So the buffers are take too long to be sent. I wonder if pulseaudio null sinks are having issues in your system. It is from them that GStreamer pipeline is taking audio. Maybe they are not being fast enough.

And it is still strange that you do not have pulseaudio logs. Pulseaudio output is very verbose. Huge amount of lines

One of the things that make this kind of problem hard to fix is that they are not easy to describe in words. Specially to non native english speakers like me. So an audio and video recording can help @AlexWayfer.

I've got it, I think. Thanks to this guide.

(Oh, I can't attach .ogg or .mp3 file here)

pulseeffects_lags.zip

I chose monotone bass track for more clarity. Do you hear these lags? I was reloaded Beatport page at the background every second, I think.

I can hear the noises. I think that they are related to the under flows. The question is why you always have them.

I think you have too many lines with underrun in your Pulseaudio's logs. I don't know exactly what they are but I don't think it is a good thing. These underruns are happening in the null sink used by PE at the exact moments you say you have the lags.

under flows

I don't know what is it, sorry.


Without PulseEffects there are no lags (and bass, lol).

But there are some logs at Beatport page reloading, maybe there can be helpful:

@wwmm thanks for the insight. I wasn't aware you weren't a non-native English speaker. your English is very good :) Anyway, I'm still battling crackling and I even got consistent crackling with a sine wave for a long time. It was just crackling for the entire time. Unfortunately, I can't reproduce such things consistently. And I don't know if it's a pulseaudio or pulseeffects issue. If I can reproduce something consistently with logs and a recording, then I will create a new issue about it because it may not be related to Alex's issue. I get underruns at the beginning of every stream, but this seems to be a pulseaudio thing. Adjusting latency didn't help anything for me as far as I can tell.

I am brazilian :-)

I took a look at my logs and sometimes I also have the underruns in pulseaudio's logs. So I guess we shouldn't worry about them. But the underflows in GStreamer I do not have.

You can investigate the cracks with the test signals. But always remember to reduce the volumes and check in pavucontrol if something is saturated. Otherwise you will always have noises even if everything is fine.

During this log there are a total of two cracks during normal audio in the middle of a YouTube music video. Unfortunately that's the best I can provide. I'm getting very similar messages as Alex, but it's happening quite rarely and seems hard to record or debug. I don't think it happens without using PulseEffects. But, it could still be some bug in the PulseAudio internal machinery that PulseEffects uses. Just mainly random rewinds basically.. What do you think is the next step towards identifying and resolving these issues?

I have confirmed that some of the cracks are due to "Unexpected discontinuity", but not all.

Alex also has discontinuity in the audio buffer before the under flows. It makes sense to me to have noises after a discontinuity. The question is if there is something that I can do on my side to fix that.

Was Chrome the only audio app opened at the moment? If yes PulseEffects would put its GStreamer's pipeline in the null state after chrome connection died. The noise could be related to the pipeline restart. I think that sometimes I hear noises when GStreamer's pipeline is restarted. I don't know yet what could be done to improve this.

Was Chrome the only audio app opened at the moment?

If you're asking me — yes, screenshot is above. But multiple tabs.

I was listening a song, and after it ended many lines like this continued to appear:

0:06:30.474472804  4344 0x564d4a5b0cf0 WARN                   pulse pulsesink.c:702:gst_pulsering_stream_underflow_cb:<sink> Got underflow

And then some red logs and everything stops. It's too long, so I'm attaching the file: pulseffects_logs.txt

Hi Guys, I had been experimenting a kind of this issue too.

With web browser streaming, with clementine playing mp3 and streaming too, vlc and any audio or video player.

My enviroment:
Archlinux
Gnome 3.28.2
Pulseeffects 4.2.4

In my case, setting the LATENCY parameter for the output in PE to its minimal value(100 us) the weird noise while adjusting volume almost disapeared...

I'm not sure if this setup is correct or "recomended" but at leats for me got better.

I hope this comment help out to resolve definitely the issue.

PE is a great software. Thanks to the developers!

Sorry about my english.

Hello! I have just released PE 4.2.5 with a few changes in the way that the block size is set. It may help with this issue. Try to play again with the block sizes values and see if there is any change

Hi Wellington.

I just updated it and same status in my enviroment!

If you need more detailed info please let me know.. I'll be happy to help.

Obrigado!

@davidgxxl I think that the issue you have with volumes has a different source than the one from the opener. I think we always had this noise when changing app volumes. It seems I have them even changing volumes in pavucontrol while PE is running.

I Looked at GStreamer logs here and it is clear that pulseaudio delays the audio data delivery whenever the app volume is changed. This delay leads to GStreamer buffer underflows that are the ones causing the noise. It makes sense that small latency values help. In this case we will be asking smaller chunks of data to pulseaudio and it will be easier for it to deliver the data in the moment GStreamer needs it. This may be a pulseaudio issue. I am looking at the code I wrote in PulseEffects to change the volumes and there is nothing that is not done by many other programs out there.

Hi @wwmm, Ok. I see!

Likewise, thanks for this amazing EQ.

Greetings.

@wwmm I've got a reproducible test case. At least for me, some stutters are coming from new gstreamer streams starting and ending. There's a very clear stutter every time it happens. This is with PulseEffects 4.2.2. I tried master branch but PulseEffects doesn't work at all with some "sie: Internal data stream error"? :( I may report a more detailed bug on that later after more investigation.

Crackling Recording (sine wave set to 0% volume): audio_stuttering_gstlaunch.zip

Played this song in the background and then I quickly ran/terminated a sine test using gstreamer several times.

https://www.youtube.com/watch?v=8b-FEaGJG8Y
$ gst-launch-1.0 audiotestsrc ! audioconvert ! audioresample ! pulsesink

Every time you hear cracks It was me starting the command and pressing Ctrl+C, starting the command pressing Ctrl+C, over and over again. An audibly identical crack occurs on both starting and terminating the command with Ctrl+C.

This does not happen when I assign the gstreamer sine test to my Default PulseAudio sink and restart the test command several times. No crackling at all.

The really strange thing is that the delay manifests itself differently depending on the song position. In that video, for the first 10 seconds I can hardly hear any distortion (although it sounds slowed down or sped up). But after that, the crackling gets much worse. Is something getting saturated as the audio gets louder in the video? But this doesn't happen when I don't run the sine test...

Crackling Recording 2 (with sine wave audible): audio_stuttering_gstlaunch2.zip

I'm doing the same thing (as you can hear the sine wave go on and off), yet the effects at the beginning (slight stuttering) are different than the effects as the song goes on (changes to crackling).

Of course, reducing latency to 100us reduces the crackling significantly, but still very noticeable :(

Could you explain what may be going on in Recording 2?

Try to reset PE after upgrading. This should help with the sie: Internal data stream error. I still don't know why a few users have this problem. It is related to the removal of plugin that is not in PE anymore.

I am able to reproduce the noise with gst-launch. It can also be reproduced by doing a few seeks in a video open in mpv. There is no special log printed by GStreamer when they happen. It is also not clear if its source is a problem in PulseEffects, GStreamer or Pulseaudio.

I forgot to say that it can only be noticed in mpv if there is also a second app playing audio. It could be 2 mpv windows for example.

EDIT:

Honestly I do not see yet if there is anything I can do about it. When all audio apps are enabled in PE the output of each of them is sent to a Pulseaudio null sink (PulseEffects(apps) in this case). Up to now my feeling is that something odd happens somewhere in Pulseaudio when a null sink receives more streams when it is in the running state

I took a look at Pulseaudio's logs when I do seeks in a second mpv window and when gst-launch is executed. In any of these events we have messages like this:

[pulseaudio] module-suspend-on-idle.c: Sink PulseEffects_apps becomes busy, resuming.
[null-sink] protocol-native.c: Requesting rewind due to end of underrun.

So whenever we add(or remove) more streams to a null sink its state alternates between idle and running. Maybe noises are introduced in this process.

In any case this secondary stream start noise and the volume change noise seem to have different sources than the ones faced by @AlexWayfer. My suggestion is that new issues are opened for them. Specially because they may require the help of people from Pulseaudio or GStreamer and it will be confusing for them to find things in this long thread.

A bit different logs at another computer without new streams creation (I'm just coding with a music in the background):

This happened with which PE version? Very rarely I have the Unexpected discontinuity in audio timestamps too. But when they happen there is only one or two of them. GStreamer is able to fix the drift without so many iterations.

This happened with which PE version?

There was a regression in version 4.2.6 causing that periodic lag. It doesn't happen here anymore in version 4.2.7

Thanks.

After upgrade I noticed:

I have always Telegram Desktop running. Can it affect?

It was a good thing to improve the logs by adding the app name. Now we know why you have the failed to move sink input errors. As you can see here #188 there is a bug in telegram that affects PE. But I am not so sure that this alone would explain all the problems you have. But it could be the trigger.

Telegram developers are aware of this problem but the issue is still open after 2 years https://github.com/telegramdesktop/tdesktop/issues/2231

@wwmm, thanks!

Also, maybe this can be helpful: https://github.com/telegramdesktop/tdesktop/issues/4219#issuecomment-411146434

He is not totally right. There will be some latency introduced of course. But this doesn't mean you can't equalize voip calls. I did this a few times in skype with no problems.

The app role will not make difference in our case. PulseEffects does not use it. It is up to the user to decide if he/she wants to apply or not effects to a given app

There is a part from v4.3.5 logs:

Based on the amount of rewinds in your log and the fact that I now know there is a bug in Pulseaudio that causes a similar effect I'd say that what is happening to you has the same source as #350.

OK, thank you, I'll watch. FYI: I didn't rewind anything.

No user can do rewinds. Pulseaudio does when it thinks it is necessary. There is no way we can influence its decision

It's probably related to https://github.com/aleho/gnome-shell-volume-mixer/issues/83

I'll monitor such issues while this extension is disabled.

Previously, I found many errors from journalctl -f /usr/bin/gnome-shell.

It's probably related to aleho/gnome-shell-volume-mixer#83

Nope, there is something else…

I don't know if there something bad. I guess, no.

But there is still the issue…

These rewinds are happening because you paused/unpaused the audio app. Rewinds are known to cause noises when changing the app volume.

I wonder if this could be caused by some problems in the soundcard driver. What is the card's model?

No! It's one stream, unpaused play.

I didn't change for while these logs were collected.

Orico SC1. It's also reproducible with Sound Blaster Play! 3 (If I remember it right).

This is odd. The line sink-input.c: Requesting rewind due to uncorking means an audio app was paused and now it is playing. If you did not do that then there is something else playing audio in the system(maybe playing silence) that is alternating between the paused and the playing state. If it is not that then chromium is creating and killing streams under the hood for reasons I do not know.

I didn't.

It's interesting. As I wrorte above, I see only Chromium in PulseEffects applications list, and I don't do anything except browsing, tabs reloading, etc.

Maybe some tabs with audio components (like for support-chat notifications) make these noises on loading while another tab (without reloading) just playing music.

It could be. Maybe the way chromium handles the creation and destruction of each tab stream is causing a similar effect to change the app volume. Pulseaudio's rewind bug is triggered and noises can be heard.

Do you have any link to this bug? Or it's just a suggestion?

The sad part (for me) here is that I can't collect enough logs of PulseEffects or PulseAudio, and even if I will report to PulseAudio "something is going wrong" there will be the one detail: these noises appear only with PulseEffects, and PulseAudio, I guess, will direct me here.

In order to apply effects we have to record from a Pulseaudio null sink monitor. But accordingly to what one of Pulseaudio's developers told in the first link if a rewind in this sink happens while we are recording from its monitor noises will be produced. As you can see in the second link this bug has been around for a while.

@wwmm, thank you! The sad story about PulseAudio (for me) :pensive: :

I found the essence of this problem: change the volume of application (Chromium for me) in PulseEffects:

(Sorry for bad quality of video record, but the sound is exact).

Also, I'm playing only one audio (tab), I don't know why there are two applications (streams). At pause (after some time) there is only the first (with playing state):

The noises caused by volume changes have the same source as #350. It is a Pulseaudio bug. I have sent some patches to its developers that will help me to workaround this bug as you can see here https://gitlab.freedesktop.org/pulseaudio/pulseaudio/merge_requests/93. They didn't merge them yet but I think that this is probably going to be done before Pulseaudio 13 is released.

I have no idea why chromium created more than one stream. But it did. At first site I thought that PE duplicated the entries but they have different latencies and when you changed the volume of the top stream nothing happened. So it is not a duplicated stream.

Yes, I remember. I just wanted to share a clear example.

Thank you very much!

Yes, maybe it's something like audio element for notifications in some tab, I don't know.

I don't experience this issue with git version of pulseaudio (v12.0.309.geadd987a6-1) and 4.6.3 version of PulseEffects, after #350 resolving. So, I'm closing this issue for now, and I'll re-open if I notice something relevant again.

Thank you very much for work. Now I can enjoy the adjusted (bass-boosted) music finally.
