[alsa-devel] VIA 82C686B AC'97 controller initialization

I'm trying to get AC'97 sound working on my AmigaOne PowerPC machine with
a VIA 82C686B southbridge and a SigmaTel STAC9752 codec. The firmware
doesn't initialize the AC'97 controller at all. Thus I had to implement
some PCI quirks, which first setup the I/O BARs of the AC'97 PCI device
and secondly power up the AC'97 controller by triggering a soft resume
event through the southbridge's ACPI controller. This seems to work fine
so far, but playback works in slow motion when I first power up the
machine. After a warm reset audio playback sounds normal.
Does somebody know how to fix this problem or were the problem could be?
BTW can the snd-via82xx and snd-via82xx-modem drivers be used at the same
p.s.: Please put me on CC:, as I'm not subscribed to this mailing list.
