Buzzing sound when audio is inactive

Hi, i am running fedora 34 on a PRIME B450-PLUS motherboard AMD. I get a buzzing sound when no sound is playing. The work around for the moment has been to

cp /usr/share/pipewire/media-session.d/alsa-monitor.conf ~/.config/pipewire/media-session.d

vim ~/.config/pipewire/media-session.d/alsa-monitor.conf

change

Code:

#session.suspend-timeout-seconds = 5 # 0 disables suspend

to

Code:

session.suspend-timeout-seconds = 0 # 0 disables suspend

Reboot

The problem with this approach is my webcam light is always active. Is it possible to fix the issue? Any help appreciated. regards jonathon
