Red Hat Bugzilla – Bug 462067
Pulseaudio causing processor spikes
Last modified: 2008-10-24 16:53:55 EDT
Description of problem:
When using pulseaudio (and xmms, but also occurs with flash, mplayer and anything using pulseaudio), every 10 seconds or so there is a stop in the music and the processor usage spikes from between 0-1% on pulse audio up to between 30 and 40% for a second or 2 then returns to 0-1%
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Ensure that pulse audio is running and play something
Every 10 seconds the music stops and the processor hits between 30 and 40%
Please run "pulseaudio -vvv" in a terminal (a pulseaudio -k might be necessary before). And paste what that outputs when those "spikes" happen.
oh, and what driver is this? I am pretty sure this might actually be a duplicate of bug 462200.

The sound from xmms completely stops (it also happens for anything producing sound, but I use xmms the most often). I'm using a SoundBlaster card if that's of any use... emu10k1 by the looks of lsmod
I am pretty sure this is a driver bug in emu10k. Some fuckup in snd_pcm_update_avail() or snd_pcm_delay()

output of pulseaudio test
I am running on an Intel system.My profile is:
Sometimes with older kernels I didn't suffer so heavy with this.Latest are a disaster
220.127.116.11-30.rc1.fc10.i686 kernel is playing fine.
Is it an issue with pulseaudio or the kernel???
Looks like the kernel is at fault...
This sounds a lot like a duplicate of 462200.
