Thanks for the response.
How did you setup pulseaudio daemon/server ?
FYI I have also created following stackoverflow question to make my needs mode clear : https://stackoverflow.com/questions/65274557/how-to-configure-pulseaudio-on-the-host-for-docker-containers

I have used pulse audio to get system audio and specific application audio output in Firefox and streamed that data to Chrome and Chromium, which does not support capturing system audio.One option would be to serve the audio data using parec or parecord from> CentOs 8 on a headless device (intel-nuc)where> my docker containers should be able to use pulseaudio client to communicate with the pulseaudio serverrequest and receive PCM or PCM re-encoded to a different codec.This can be achieved using a server-client template, e.g., fetch('/http://localhost:1234?device=microphone'), parse the PCM response at the client containers https://github.com/WebAudio/web-audio-api-v2/issues/97#issue-688754941. Other means of achieving the requirement include using WebRTC PeerConnection https://gist.github.com/guest271314/04a539c00926e15905b86d05138c113c.PulseAudio has a WebRTC Audio Processing component though I have not tried that either.

I would like to run pulseaudio server on the host (CentOs 8) and my docker containers should be able to use pulseaudio client to communicate with the pulseaudio server via pulseaudio unix socket.
Moreover it should be possible that different docker containers can access the microphone and speaker at the same time.The main problem I am facing I have reported in following forum post:I also think that pulseaudio has the good requirements for use in a container setup if I only can make it work.Jan.
