Bug 13599

I have an Asus Xonar D1 card in my computer.  It works great for days at a time, but if is suspend the computer, when I resume later I have no sound output.  The module is still loaded after resume, and pulseaudio still detects the card rather than showing a null output.  The only way I have found to restore the sound is to first kill pulseaudio and anything else using the sound card, then unload and reload the snd_virtuoso module.  Even using rmmod to remove only that module and leaving snd_oxygen_lib and the rest of the underlying sound modules in is enough to restore the sound.  I first began to notice this with the 2.6.27 kernel in Fedora 10, but I did not own the card before then so this problem this problem probably didn't start there.  I am currently experiencing the problem with the 2.6.29 kernel in Fedora 11, currently their version is 2.6.29.4-167.  I am experiencing this on x86_64; I have not tried 32 bit.  Here's some extra info:

I have searched through the change logs for 2.6.30 and I haven't noticed anything that seems related to this issue, but I am willing to test it on this machine if someone thinks it might behave differently with my sound card.  Let me know if I can provide any more info or test anything.  Keep up the good work.
