snd_hda and 8.2-RC*

Hi

I have recently installed new version of FreeBSD 8.2-RC2. On the new version i'm having trouble with sound.
When I load hda_snd.ko driver I get an error msg
Code: 
hdac0: <ATI SB600 High Definition Audio Controller> irq 16 at device 20.2 on pci0
hdac0: HDA Driver Revision: 20100226_0142
hdac0: [ITHREAD]
hdac0: hdac_get_capabilities: Invalid corb size (2)
device_attach: hdac0 attach returned 6

and /dev/sndstat
Code: 
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:

Does anybody have any ideas how to fix this?

Thank you in advance

This won't fix it, but if you have another audio interface card installed in addition to your graphics card's one (e.g. an on-the-mainboard one) you can work around this by setting your system to use that one instead, i.e. setting hw.snd.default_unit to the handle number of your additional audio adapter (detected e.g. by running "sysctl dev.pcm" and looking for it's name in dev.pcm.handle_number.%desc) and reconnecting your audio output devices to the other audio interface card.

Hi,

I have no luck today :)

Hmm...  Looks like a unified diff to me...

                 sc->corb_size = 256;

In my opinion the problem is not in the code, but in hardware, because I have changed RAM from slot 1 to slot 2 and sound started to work again. :/
 
I have this problem with CURRENT, before (1-2 months ago) all was OK.
