Jitsi-meet: Cannot gain access to microphone

Created on 3 Apr 2020 · 10Comments · Source: jitsi/jitsi-meet

Description

When connecting to my self-hosted jitsi Meet via Firefox, the app can't get access to the microphone.

A popup is shown saying:

AudioContext.createMediaStreamSource: Connecting AudioNodes from AudioContexts with different sample-rate is currently not supported.

I don't have this issue when connecting through the same browser to a different instance (I've tested jitsi.riot.im on Firefox and it doesn't show this error)

Environment details

Firefox 75.0b10
Not sure how to check my version of jitsi, but I'm running docker-jitsi-meet on ebfa142d384466fefc7cd224cdca50df9cfe40c7, a commit from 2 days ago

Hello everyone. This doesn't reproduce on the release version of Firefox which is 74. However I did manage to reproduce on the beta version 75.|
It has to do with the audio processing we do for detecting speech using Web Audio, it looks like Firefox changed an API there, namely the expected PCM frequency when creating a media stream source AudioContext.createMediaStreamSource().
At this point idk if it's an easy fix, or something more complicated. Will investigate it.

@andrei-gavrilescu any news about this? Thanks

Tested in Firefox 76.0b4 and can confirm that my microphone does not work at all. (sample-rate error as reported above) For now, I'm using Firefox ESR 68.7.0esr as a fallback and the microphone works fine there, although I can imagine that's not an option for everyone.

Did you report in Firefox issue list? I saw several reports there. I have not idea if it is a bug from Jitsi or Firefox, but I think it is good that both check, don't you think it?

Hello everyone, sorry for the belated response.
After an initial investigation it turns out that a resampler is required to make this work in firefox, which is not trivial. It will be added after more urgent issues are taken care of.
From what I tested so far the error doesn't seem to affect the conference flow i.e. audio/video still work, however the talk while muted, and noise detection notification won't work.
Don't think it's related to https://github.com/jitsi/jitsi-meet/issues/2835 as the microphone not working might be something else.

Fwiw, getting this error on Fedora 32 with Gnome 3.36.2 on Wayland, and Firefox 76.0.1 (64-bit)

Not sure this is helpful, but if this is hard to fix, it would be valuable to me to be able to use the microphone without speech detection on Firefox, as it is the only browser that can share the entire screen over webrtc when using wayland.
