I am using a fresh system with PulseAudio. This system previously did not have this issue when using GNOME, but with this reinstall I am using i3wm without a DE.

The issue is that after my analog audio output idles for a few seconds (between 5 and 10), it begins to buzz. As soon as something opens the audio device (including pavucontrol), the buzz goes away.

My suspicion is the device is being disabled after idling and some interference from the AC power source is causing the noise.

I don't want to have to make something hold ownership of the device, because sometimes I use other software that doesn't play nice with PulseAudio and I need it to access this device.

What can I do to remedy this behavior?

I found in /etc/pulse/default.pa and /etc/pulse/system.pa a line:

load-module module-suspend-on-idle

After commenting these out, the problem is solved.
