[Pulseaudio] Pop sound when the first stream starts, auto-suspend?

Hi,

I've been having a popping sound issues whenever a Pulseaudio sink was opened. At first I thought it had a link with the power saving settings of snd_hda_intel, so I changed those two settings:

power_save setting = 0
power_save_controller = N

Sadly, it doesn't change anything.

I also tried to disable auto-mute in alsamixer. It didn't work.

Then, I tried to investigate on pulseaudio's side, and figured the sinks are disabled when they are idle, so I commented out this statement in /etc/pulse/default.pa:

### Automatically suspend sinks/sources that become idle for too long
#load-module module-suspend-on-idle

However, if I do that, the device will still be suspended when the last stream ends, but won't come back to life except if I select the device again in pavucontrol while a sound stream is running (super weird).

Any leads? I'm a bit desperate...

EDIT: I'm experiencing what's been described here: Red Hat - Bug #520403 - but the solution they proposed does not work for me. I also followed the guide for ALSA Setup on the wiki, and read the section talking about Popping Noises, but nothing works for me, I un-muted the Line-In too. FYI, my audio codec is a Realtek ALC892.

EDIT 2: Noticed it does the same thing when I mute the volume.

Thanks!

Gabriel
