Some participants are lacking audio #9805

zabbal · 2021-08-25T18:04:35Z

Description:

While in jitsi meet conference I sometimes experience no audio from some participant. At the same time I can see their screen (when shared) and I can hear audio from other participants.
Is there a way to debug this sort of issues? Perhaps it's an issue others have hit already? Some odd NAT-related problem?

Steps to reproduce:

It seems to be specific to some participants but not the others. Note: I do not hear the audio from participant X but I can hear audio from participant Y and Y can hear X's audio.

Expected behavior:

Audio always works.

Actual behavior:

Audio sometimes works.

Server information:

Ubuntu 21.04

Client information:

Ubuntu 21.04
Falkon 3.1.0

Additional information:

Not sure how this can be tracked down - any ideas would be appreciated.

Sorry but in the template you have missed this important notice:

General questions regarding usage, installation, etc. should be posted at https://community.jitsi.org. They will be closed if posted here

general questions are something along the lines of 'not sure on how to debug the issue ?'. You also ask if others have your issue, while the template states explicitly that it is your responsability.
.
So be kind enough to close this issue and post your question where it belongs, on community.jitsi.org.

Lack of audio for some participants of the call is not "general question" - that's a bug in jitsi-meet which needs to be fixed.

gpatel-fr · 2021-08-30T05:38:19Z

if you say so... The point is that you did not provide nearly enough information for a developer to operate on it.

zabbal · 2021-08-30T07:17:23Z

Yeah, that's how some bugs are. And that's why we have public issue tracker - so others can contribute and together we can resolve the bugs. Please refrain from random comments unless they actually provide useful information towards that goal.

damencho · 2021-08-30T11:40:52Z

Do you experience it on meet.jit.si? If not which version is that you self host?

zabbal · 2021-08-31T07:13:54Z

I've seen this happening twice on self-hosted instances. I don't know version in first case (happened couple of months ago), in more recent case it was 2.0.6173-1 - installed on latest Ubuntu via jitsi-provided packages.

The configs are available at https://github.com/emacs-berlin/emacs-berlin.org/blob/gh-pages/ansible/jitsi.yml

I suspect it might be smth TURN/STUN related but unsure how we can troubleshoot this. Is there some particular log setup or settings we could try?

damencho · 2021-08-31T11:27:36Z

Do you have pre-join screen enabled? If not, try that.

Gathering logs from the client that is not hearing some and the id of the participant that is not heard and sharing it with us is next step.

zabbal · 2021-08-31T12:15:55Z

Yepp, pre-screen is enabled. The audio is broken one-way: I can hear some participants and the participants I can't hear have no problem hearing me.

damencho · 2021-08-31T12:55:12Z

So when this happens you can note the id of the participant you don't hear and save your js console logs and send it here. Thank you.

Rintan · 2021-09-13T13:33:52Z

I have the same issue.

Here is my javascript console logs.

I also found the same issue on lib-jitsi-meet.

jitsi/lib-jitsi-meet#1693

Rintan · 2021-10-06T13:26:54Z

Pre-requirements

Pre-join (pre-meeting) page enabled
Using authentications (I've tested on jwt token authentications)
Jitsi Meet 2.0.6173 or newer

Steps to reproduce

Some participants can't hear others audio though they don't muted.

Server information

Ubuntu 20.04

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

zabbal · 2022-08-08T07:20:09Z

I've noticed that this can be "fixed" by closing the browser tab and re-joining the conference in a new tab. So it's not some generic browser or network connectivity issue - that's smth jitsi-specific.

zabbal · 2022-08-08T09:06:21Z

Also, can we re-open this - the issue still affects multiple users without proper fix. Keep closing and opening jitsi is also hardly acceptable workaround.

3ynm · 2022-11-25T16:43:09Z

Same thing happened me during my first class on a course. 3 people out of 13 had problems hearing some other people (but not every other people). I've lost some students because of it :(

damencho · 2022-11-25T18:14:50Z

Please do not use old threads. Open a new topic in the forum explaining the problem. What deployment do you use? Is it meet.jit.si? If you are hosting your own maybe upload the config.js and what versions of the packages do you use? What browsers and versions were used by those that do not hear? Have you managed to download some client logs (browser js console logs)?
