Description Trever Adams 2012-05-02 00:32:32 UTC 
Description of problem:
If my computer goes to sleep, the audio does not come back properly. (CD audio, PCM, it is all dead.) If I kill pulseaudio, rmmod and modprobe snd_hda_intel, things work again.

The two related devices are:
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
01:05.1 Audio device: ATI Technologies Inc RS780 Azalia controller

I believe 14.2 is the one in question as RS780 is HDMI, I think.

Version-Release number of selected component (if applicable):
kernel-3.3.2-1.fc16.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. Put computer to sleep
2. Wake it up
3. Try to use audio
  
Actual results:
Working audio.

Expected results:
No sound!

Still in F17 kernel-3.4.3-1.fc17.x86_64

I'm guessing this still happens with 3.4.4-5?  Please attach the output of alsa-info

Alsa info

The bug is only intermittent I now (mostly gone) for the last kernel or two (particularly the 3.4.4-5).

However, the problem is now is that instead of no audio, it is a hiss that doesn't really go away (sound idle or sond playback). Also, there are ocassional clicks or pops that weren't there before in both idle and playback.

Is this still a problem with 3.8.2 in updates-testing?
Comment 5 Trever Adams 2013-03-18 19:33:08 UTC 
I have only had a chance to test this lightly, but it does seem to fix the problem. Thank you!

Thanks for letting us know.
