Juliusz,
Thank you very much.
It appears in the inputs - Linux/Pulseaudio. I suppose that the new tab participant will be effective though it must be muted to prevent feedback. I will try later and OBS also - very good. I did not know that sharing the tab would include its audio. This is not a web audio though but rather is another program on the computer.
Best regards,
Charles

Hello,

I wish it were possible to share an additional audio stream, that could be a
monitor/loopback from the computer, in addition to the mic input. This would
be useful for sharing playing or editing audio+video.

Does your extra stream appear in the list of inputs in the side menu?  If
so, then simply open an extra browser tab in which you set "Video" to "none"
and "Audio" to your stream.

Are you able to play your stream in a web browser?  If so, then the
simplest solution is to share a browser tab that plays your stream (pick
the share screen button at the top, then share the tab that's playing the
audio stream).

Are you able to get your audio stream into OBS Studio?  If so, then the
simplest solution would be to push it into Galene over WHIP.  See

If none of the above work for you, then we'll need some extra information.
What platform you areusing (Linux, Mac OS X, Windows), and how do you
access the extra audio stream.
