[pulseaudio-discuss] How manage volume remotely on pulseaudio

[guest271314]

One alternative solution is configuring a proxy on computer B to route all
specific domain requests through A, using WebRTC on each computer, capture
the video and audio on computer A, test the volume using Web Audio API
AnalyzerNode, adjust the volume accordingly, add the track to the
MediaStream that is played on computer B.
