Hi,
as there have many problems reported for VIA codecs, I started looking at the driver code, and decided to rework on it. [snip]
After not being able to compile the kernel from git, I now compiled modules from today's snapshot (up to 7b5017f56c69ef88f92e6472ec2578708b892211).
I will describe what worked for me and what did not, as I lack the experience to point to details in the code.
* When enabling Dynamic Power-Control in alsamixer, I get no sound, except on the internal SPDIF output.
* Independent HP worked, when I could turn it on in alsamixer and correctly produced sound with aplay -Dhw:0,2,0 . I could not always reliably enable Independent HP in alsamixer, sometimes it would not change status ans aplay claimed that hw:0,2,0 was busy.
* Headphone automute (muting rear line out when headphones are plugged in, if I understand correctly) does not seem to work in any setting.
* I can only get SPDIF output from the internal connector on the mainboard (pin 0x20 if I interpret hda-analyzer correctly) and not from the SPDIF socket on the rear panel. It looks like this might be pin 0x21, which looks like an SPDIF Input in hda- analyzer, but the mainboard manual says that this should be an output.
* Output of alsa-info.sh is attached.
