[jitsi-dev] Jitsi <--> Chrome audio issues


#1

There is an issue between jitsi-videobridge and chrome where a *speaker can
not be heard by all participants* of the call but only by some.This seems
to be known issue in Chrome and probably well known for jitsi, too. It
strongly impacts our user experience, meaning a large percentage of our
users encounter this problem. We are running jitsi-videobridge tag 840 and
most customers are running Chrome 54/55. Are there *advised versions in the
video bridge and Chrome* that reduces the occurrence of this problem? Is
there a roadmap in *jitsi-videobridge and chrome* to address the issue?

Thanks,

J.

Hi Johann,

Chrome indeed has a bug (https://bugs.chromium.org/p/chromium/issues/detail?id=403710) for which the JVB implements a hack, but it doesn’t always work well. We are aware of this.

If you can tolerate bad lip-sync, you can try setting enableLipSync: false in the config.js of your jitsi meet deployment.

I hope this help.

Regards,
George

I guess the referenced hack is this one:
https://github.com/jitsi/jitsi-videobridge/blob/master/src/main/java/org/jitsi/videobridge/LipSyncHack.java

What are the effects if we disable 'lipsync'?

Chrome will not attempt to synchronize audio and video as they come in.

Most of the time you wouldn't notice any difference.
