Description Bruno Medeiros 2009-07-23 05:50:26 UTC 
Description of problem:

pavucontrol causes full load on processor and hangs after few seconds.

Version-Release number of selected component (if applicable):
pavucontrol.x86_64 0.9.8-1.fc11 

How reproducible:
Always.

Steps to Reproduce:
1. Open pavucontrol
2. Wait few seconds.
3.
  
Actual results:
pavucontrol causes a full cpu load during few seconds and after crashes with the following message: Connection failed: Connection terminated

Expected results:
pavucontrol remains opened and working correctly an arbitrary period of time, without cpu overloading.

Additional info:
This error starts when I upgraded from fedora 10 (was previously 9) to fedora 11. A have another issues here, my extra channels started working only after increasing alsa volume with the old volume control, as described here: http://fedoraproject.org/wiki/Common_F11_bugs#PulseAudio-based_volume_control_cannot_adjust_volume_satisfactorily

I have a lot of messages in /var/log/messages and I will fill another bug against alsa about this. (have attached messages log her too).

Your sound driver seems to be broken. The intresting line is this one:

snd_pcm_delay() returned a value that is exceptionally large: 6377097072352565504 bytes (326791786697 ms).

If it's expected that the alsa error causes de pavucontrol full cpu load and crash, I believe that this bug is really a duplicated of https://bugzilla.redhat.com/show_bug.cgi?id=501769
