Description Miguel Angel Perez 2010-08-01 18:37:59 UTC
Description of problem:

With fedora 12 sound worked fine, but afer doing a clean installation of fedora 13 the sound seems to randomly stop for a few milliseconds and then the sound continues, some times there are some "clicks" and a small part of the skipped sound is played at the same time it plays the next part. I've been following instrucctions found in https://fedoraproject.org/wiki/How_to_debug_PulseAudio_problems but nothing seems to work for me.

This behaviour seems to be a bit fuzzy as some days I can use sound as I always did with fedora 12 but other days I cannot use any app that outputs sound, as each time the sound stops the application seems to freeze, so any of those apps are unusable for me (flash-based apps, music players, video players, etc).

I've tried to check if this is a sound driver problem listing devices with aplay -L and using front instead of Default and it seemed it was.

Version-Release number of selected component (if applicable):

"uname -a" output:
   Linux hyperion.lan 2.6.33.6-147.fc13.i686.PAE #1 SMP Tue Jul 6 22:24:44 UTC 2010 i686 i686 i386 GNU/Linux

This is an up-to-date fedora 13 setup.

How reproducible:


Steps to Reproduce:
1. You need my laptop
2. Use an app that produces some kind of sound output
3. Listen to sound stopping and getting back all the time (irregular timming).
  
Actual results:
I can't listen sound properly. Even some apps hangs while playing sound under too much stop-continue weirdness.

Expected results:
I can listen music, whatch videos in youtube and play games without sluggish sound.

Additional info:

I've collected as much information as I can.

The output of "lspci | grep -i audio" is:
   00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

The output of "cat /etc/proc/asound/pcm" is:
  00-00: ALC268 Analog : ALC268 Analog : playback 1 : capture 1
  00-06: Si3054 Modem : Si3054 Modem : playback 1 : capture 1

I've also got some output of pulseaudio -vvvvv and aplay that shows a lot of underruns. These along with alsainfo output are added as attachements.

Comment 8 Miguel Angel Perez 2010-08-04 10:45:38 UTC
Latest kernel update doesn't solve it.

current "uname -a" output:

  Linux hyperion.lan 2.6.33.6-147.2.4.fc13.i686.PAE #1 SMP Fri Jul 23 17:21:06 UTC 2010 i686 i686 i386 GNU/Linux

Comment 9 Miguel Angel Perez 2010-09-01 09:17:55 UTC
Latest kernel update (2.6.34.6-47) doesn't solve it. Any app with sound is almost unusable.

Comment 10 Miguel Angel Perez 2010-10-30 08:52:00 UTC
Hello. I'm still here with this issue with latest kernel update 2.6.34.7-61 (PAE).

But I've found one interesting thing. When the sound gets crazy if I start up a process that will try to use 100% cpu (my laptom is a dual core cpu) the sound starts to work as spected.

This makes me think that I might be wrong about the alsa driver being guilty of this nuissance. But I tried common pulseaudio troubleshotting instructions and nothing seemed to work, so now I'm not sure of what to do next.

Comment 11 Miguel Angel Perez 2010-12-09 09:07:48 UTC
I've closed it as with Fedora 14 things seems to work a bit better (sound is almost usable but with glitches) and I'm not sure if this is a driver or pulseaudio thing.
