Can't Add 2nd Audio Track To Conference

We’re trying out multiple streams per endpoint in the newer Jitsi version. Originally we had camera and screenshare as 2 separate connections so it’s nice to consolidate these.

Adding a 2nd video stream, like for a screenshare, works but as soon as I try add a 2nd audio track I get an exception. For example when I try add a screenshare that has computer audio enabled, it complains when I try add the audio track

I’ve included a screenshot for reference

Jitsi 2nd Audio Error 2022-11-16 163129

I see that Jitsi Meet is able to have a screen share with audio at the same time as the camera, so I guess I’m doing something wrong, but I can’t figure out where I’m going wrong.

I don’t think we support multiple audio streams.

We use a WebAudio based mixer in the screenshare-with-audio case.
