Chrome users only hear some participants

Hello guys,

We have been testing our own Jitsi installation and had issues with certain Chrome users who could not hear all participants. We had a meeting with 5 participants, all of them using Chrome and some could only hear one, another only heard 3, and others only hear 2. The video didn’t have any issues.

Next is the environment description of the users:

User 1: Mac Chrome v81.0.4044.92
User 2: Mac Chrome v81.0.4044.92
User 3: Mac Chrome v80.0.3987.163
User 4: Mac Chrome v80.0.3987.163
User 5: Windows Chrome v81.0.4044.92

Next are the problems:

  • User 1 couldn’t hear users 2 and 3.
  • User 4 could only hear user 2.
  • User 2 couldn’t hear user 4.

What could be causing this and how can I solve it?

Next are my configuration files in case one setting could be caussing this:

/etc/jitsi/meet/my.domain.unico-config.js

I am getting this messages in the Chrome of the participant with audio issues:

instrument.ts:129 2020-04-15T20:53:38.765Z [modules/statistics/AudioOutputProblemDetector.js] A potential problem is detected with the audio output for participant 061c032f, local audio levels: [0,0], remote audio levels: 0.1295205542161321

Has this anything to do with this?

Can you make sure you have this in your config.js enableLipSync: false, and report do you see the problem after adding this.

@damencho, I set enableLipSync: false in /etc/jitsi/meet/my.domain.com-config.js. The problem still occurrs:

Now we used Android’s Chrome and the same issue arises. Next is a screenshot of the console messages:

We made a new test with 4 devices:

  1. Windows 10 w/Chrome 81.0.4044.113 Could hear all
  2. MacOs 10.14.6 w/Chrome 81.0.4044.113 Could hear all
  3. Android 9 w/Chrome 81.0.4044.96 Could hear all
  4. Android 10 w/Chrome 81.0.4044.96 Could not hear 3

Stopped all services in Jitsi server (prosody, jicofo and jvb). Deleted the logs, restarted the services, reproduced the issue and stop the services again. The warning and severe entries in the logs are the following:

prosody.err

empty

prosody.log

no warnings except sigterm when stoping services
