Some participants not able to hear each other

Hi team,

We are seeing a serious issue on our meetings where some participants weren’t able to hear other. I have attached console logs for the user I wasn’t able to hear but others were. User I wasn’t able to hear joined the meeting from chrome browser running Version 110.0.5481.177

Jitsi version: stable-7882

Weird thing I noticed was difference in Tracks object in the logs. After he re-joined, tracks array was populated vs not before.

Is this a known issue? What should be the fix? This sounds little serious so.

Have a look at this thread, sounds it is related to what we are seeing as well. The Jitsi dev. team is working on a fix as far as I understand

I am not sure - if both are really the same issue - since in our case, there were few participants able to hear the above participant vs few others were not able to hear him. He had to rejoin to make sure everyone were able to listen.

Is this a known issue? Or any idea on potential issue here?

The issue happens randomly - Sometimes, it works vs sometimes break for some participants.

I noticed the remote participant was speaking (can see video) but I couldn’t hear him and his tile was showing mute button. Same time, there were other participants able to hear him. I had to rejoin to hear him back.

There are multiple issues that were fixed and can be causing this when looking at the date of your version. So you can update to the latest stable.
