[Solved] guvcview no pulseaudio webcam sound input, suspended audio

I have just resolved a long-standing issue I had where guvcview would not record my webcam audio input unless I had "pavucontrol" running while guvcview was running and capturing.

It came down to running this command:

pactl list sources

which showed that my webcam microphone was suspended.

Changing in "/etc/pulse/default.pa":

load-module module-suspend-on-idle

To:

#load-module module-suspend-on-idle

And restarting finally fixed the issue.

On the pulseaudio page: https://wiki.archlinux.org/index.php/Pulseaudio

It does mention module-suspend-on-idle but only talks about it in the context of bluetooth audio, not guvcview and webcam audio.

On the webcam page: https://wiki.archlinux.org/index.php/We … uvcview.29

There is no mention of any kind of microphone troubleshooting that would involve the pulseaudio suspended input.

So, if I was to add this solution for my webcam microphone being suspended and that causing guvcview to not get audio input from that unless pavucontrol was running at the same time: which page (or both) should this information be added to?

Added guvcview to the PulseAudio Wiki page:
