I'd also look towards OBS solution.
In the previous week, I was looking for streaming both video and audio
from OBS Studio to Jitsi.
I found this Github thread:
For the video, you can use the following OBS plugin:
This plugin uses the v4l2loopback kernel module.
For audio, some user suggested to create a virtual sound card with `sudo
See this comment:
With this solution, you should be able to configure volumes of "Desktop
Audio" and "Mic/Aux" in OBS's Audio Mixer and stream it to ffmpeg which
forward the stream to the virtual audio card.
Then, you can use the virtual audio card as your microphone in Jitsi or
any other software / web app.
However, this solution may have latency. If you need low latency, I
guess that you'd need to ditch ffmpeg and use Jack instead of pulseaudio
but I'm not sure which way to go.
Hope it helps :)
