But I am not observing any problem related to working of sound card.
Obviously sound after sleep and hibernate is broken, but patch needs to
be modified for that. Can you explain any not so obvious problem due to
this fault?

My bad. I had disabled HDMI codecs through BIOS. When enabled, current
patch fails because it detects non zero probe mask(only for HDMI
though). Will attach modified patch soon.

Attaching revised patch with new alsa-info. This patch doesn't look so
good because codec-to-be-probed is assumed at location 0 and other
discovered codecs are not considered. But if this bug is only present in
this chipset, in my opinion this should be good enough.

Let me try to explain my findings:
How does this magic sequence come?
By dumping Win7 driver's init sequence and reproducing it through ALSA driver.
why does it need to set UNSOL flag at first?
No such need, I've put it after regular init so that only affected chipsets are
reset again. Putting
you have to provide output of alsa-info.sh when both codecs are detected

Ok. So to try to get this into upstream, you need to test this with the
latest upstream driver, and I need to know *where* this code was added,
too.

Cool stuff. I've never looked at PCI IOMMU traces before.
I don't see anything obvious when looking at those traces though, so
we're probably looking at some type of chipset bug here.
I guess we're down to trial and error then? I e, try random changes to
stuff that win7 does but we don't (or the

I finally have some good news. I installed Win7 guest using qemu and
passed pci card to it. Win7 was able to detect it. I closed Win7, and
reinserted snd_hda_intel, and now it detects both analog and digital
devices. I tried it couple of times and it worked. So and ugly hack to
get it working.

From windows 7 I found out that realtec ALC662 codec is located at
location 0 on HD Audio bus.
Is there any more information here that could be relevant, such as the
PCI bus address of the ALC662 codec as well as the HDMI codec?

I am suffering from same problem. So when I looked at motherboard

for 7.1 HDMI and other 5+1 HD audio via Realtek ALC662 codec.
