Pulseeffects: Pulseeffects randomly freezes when changing srs-file.

[tnilzon]

In the Convolver section and when changing irs-file, Pulseeffects randomly (and quite frequent) freezes. The sound that is playing goes to silence, and Pulseeffects does not react on mouse clicks (it is frozen). The only way to get it going again is to force a shut down, and restart it.

What is the size of the impulse files you are using? At least here on my computer (Arch Linux) impulse files of 8 MB take around 2 seconds to load. While this is happening there is silence indeed. But after that PulseEffects continues to play sound with no problems. No need to kill it.

Kill the current instance pulseeffects -q and restart it in debug mode G_MESSAGES_DEBUG=pulseeffects pulseeffects. Maybe the logs will show what is happening in your system.

Size of irs files are only about 100-200 kB. This is an example of a log when Pulseeffects freezes:

(pulseeffects:30473): pulseeffects-DEBUG: 09:57:28.980: convolver: irs file: /home/tomas/.config/PulseEffects/irs/srs_hd_audio_lab_01.irs

The irs file is below, just change the extension to .irs

srs_hd_audio_lab_01.txt

Here is another example (with a bit different error):

(pulseeffects:9801): pulseeffects-DEBUG: 10:09:42.693: convolver: irs file: /home/tomas/.config/PulseEffects/irs/SRS_1_1_Normal_stereo.irs

SRS_1_1_Normal_stereo.txt

Note also that the freezing occurs randomly, not every time with these irs files. Sometimes it works just fine, and sometimes it freezes. I have also experienced this behavior on Manjaro gnome (so it is not related to KDE only).

It is freezing because it is crashing. Lines Segmentation fault (core dumped) and corrupted double-linked list. For some reason I have a crash only when I alternate irs files multiple times. Sometimes 20 times. Sometimes I have to alternate 50 times.

In any case it seems I am doing something that is making GTK crash when the irs data is plotted in the interface.

I did some changes that seem to have fixed this issue. Are you able to test them using this aur package https://aur.archlinux.org/packages/pulseeffects-git/ ?

[tnilzon]

I have now tested your new AUR package (pulseeffects-git 4.5.0.r23.g7e3852cf-1).
After trying this multiple times, I can confirm that it seems fixed, no crashes so far!
Very good (and fast) job. I use the Convolver alternating irs files quite frequent, and this has been frustrating.

Once again many thanks, Pulseeffects is really a great audio tool for me in Linux, also using it on my Linux-HTPC connected to a home stereo. The result on audio quality (e.g. Spotify) is amazing!
