Thanks. I knew about this. However the media utility (VLC Media Player) in Raspberry OS doesn't work for me in this regard. I tried to install pavucontrol without success. Look at the attached file showing my attempt. Do you know what to do with this or have another method to get pavucontrol installed.
This was the result from https://rivendell.linuxfromscratch.org/blfs/view/10.0-systemd/multimedia/pavucontrol.html
Before this attempt, I used snap to install PulseAudio on the Pi....successfully...I think.....This may be of no concern.
