Thanks for the reply.
I've - thanks to i-garrison on irc - found out one of my loopbacks was muted. I missed this over and over and over again in trying all kinds of weird permutations of the above.
It works now ;) not perfect, but it works for what I want it - which is piano classes ;)
Thanks

One approach would be to create the virtual device for the MIDI output alone. Then capture both MIDI output and headset microphone tracks individually using exact constraints at getUserMedia(), then connect each individual MediaStreamTrack to a Web Audio API MediaStreamAudioDestinationNode where both tracks will be playing in that stream, for example, see https://stackoverflow.com/a/40571531.On Sat, Jan 16, 2021 at 9:55 AM Jan De Luyck <ml+pulseaudio@xxxxxxxxx> wrote:Hi folks,I'm trying to send the output of an usb-connected plantronics headset and my digital piano (using midi + fluidsynth) over google meet/zoom/jitsi/.. to the other side.

My voice / mic never gets picked up.I've tried recording usingparecord --channels=2 -d mix-for-virtual-mic.monitor /tmp/x.wavbut same story, only the piano is being picked up.What did I miss? In all logic, this should work?Kind regards,Jan_______________________________________________pulseaudio-discuss mailing list_______________________________________________pulseaudio-discuss mailing list
