gnome-volume-control loses cound card, becomes null device

Pulse audio vvvverbose output
Description of problem:
Sound appears to work fine with pulse audio running, but when I open gnome-volume-control (or alternatively pavucontrol), the card goes away immediately, causing gnome-volume-control to report that I have no sound card, just a null device. Sound is no longer available to other apps, but if I kill pulseaudio it will respawn and the card comes back provided I don't open volume control.
Version-Release number of selected component (if applicable):
Just open gnome-volume-control. Card is CA0106
D: alsa-source.c: snd_pcm_mmap_commit: Broken pipe
D: alsa-source.c: snd_pcm_mmap_commit: Buffer overrun!
I: (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_PREPARE failed
I: (alsa-lib)pcm.c: cannot recovery from overrun, prepare failed: Device or resource busy
E: alsa-source.c: snd_pcm_mmap_commit: Device or resource busy
There's something wrong with your card and PA tries to to reinitialize it and that fails.
Reassigning to kernel. Please include the data alsa-info.sh --no-upload generates here!

This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '11'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 11's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 11 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
