Description Paul F. Johnson 2008-09-12 08:17:35 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): 0.9.12-4 How reproducible: 100% Steps to Reproduce: 1. Ensure that pulse audio is running and play something 2. 3. Actual results: Every 10 seconds the music stops and the processor hits between 30 and 40% Expected results: No spikes Additional info:

Please run "pulseaudio -vvv" in a terminal (a pulseaudio -k might be necessary before). And paste what that outputs when those "spikes" happen.
Comment 2 Lennart Poettering 2008-10-03 09:05:32 EDT
oh, and what driver is this? I am pretty sure this might actually be a duplicate of bug 462200.

Created attachment 319363 [details] Pulseaudio results
Comment 4 Paul F. Johnson 2008-10-03 09:45:19 EDT
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
Comment 5 Lennart Poettering 2008-10-03 16:30:27 EDT
I am pretty sure this is a driver bug in emu10k. Some fuckup in snd_pcm_update_avail() or snd_pcm_delay()

Created attachment 320793 [details] output of pulseaudio test I am running on an Intel system.My profile is: http://www.smolts.org/show?uuid=pub_2dabf29b-bd26-4825-b7ed-ac1db85fec24 Sometimes with older kernels I didn't suffer so heavy with this.Latest are a disaster
Comment 7 antonio montagnani 2008-10-20 07:41:16 EDT
18.104.22.168-30.rc1.fc10.i686 kernel is playing fine. Is it an issue with pulseaudio or the kernel???
Comment 8 Paul F. Johnson 2008-10-20 07:56:11 EDT
Looks like the kernel is at fault...
