That driver will have to be updated to reinitialize the card properly 
after resume.. Have you reported this to the ALSA people?

PROBLEM: snd-au8830: dead after software suspend

[Gert Robben]

After a suspend-resume cycle (using Suspend2), my sound card doesn't 
work anymore. It works again after reloading the module.

dmesg, initial boot:

----8<----
> PCI driver au8830 lacks driver specific resume support.

dmesg, after resume, trying to use the card:
> vortex: ac97 codec stuck busy

Thanks for any help!

No, I thought this might as well be something for PCI or PM people, and 
I expected some ALSA people are also reading this list.
If not, where else should I report this exactly?

alsa-devel would seem to be a good starting point - see
http://www.alsa-project.org/mailing-lists.php
Also, the author of the driver, Manuel Jander <mjander@embedded.cl>,
would probably be a good person to add to Cc.
And keeping LKML on Cc while sending to above people usually never hurts :-)

You also may want to file a bug at http://bugzilla.kernel.org .

If you decide to do that, please file it as
"Power Management"->Hibernation/Suspend bug, I'll redirect it to the ALSA
people.

Greetings,
Rafael
