Hi Raymond,
I spent a little time reading sound documentation but doesn't find anything about how to apply a patch to snd-hda-intel, but it is needed? there is no an "patch auto detect"? i enable the patch option in HDA-Intel kernel config, this WE i will study more, Takashi could you please give me documentation about patch applying?
The easy way is to use Takashi 's daily snapshot since there are a few patches related to alc892
About the NVIDIA video card, do you think that the hdmi on NVIDIA could conflicts with the one in motherboard, creating the problem that I'm experiencing? I didn't check anything on kernel regarding HDMI, and i use an "edited" NVIDIA driver (by me) to build against 2.6.39 (only rename smp_lock.h to smp.h in the code) version is 270, taken from gentoo repos.
you have to ask nvidia hdmi expert or asus forum
To clarify my self
- I *need* to apply alc662 patch to snd-hda-intel to test if commits work?
- I *need* to solve problems with NVIDIA drivers to make my sound card
work? (and if i must specify witch port nvidia must use how i could do that?)
- alsaconf doesn't find my sound card, even when it works (crackly but
works) is this problem linked to capture streams problems ?
No need to do anything if Takashi mention that model="auto" is used to support 6stack motherboard
Some news:
- after module loading I hear a big noise
- after upgrade to Takashi's sound-2.6 kernel tree, i hear dx louder than
sx
- some times the sounds mute, after 7/10 seconds sound come back (no
changes in alsamixer)
I know that I'm completely usefulness and a little bit annoying, I'm reading about alsa devel but I gess is a little bit hard for me.

As you have specifed in BIOS setup that "Front Panel Connector" is [AC97] and the BIOS seem set "Misc=NO_PRESENCE"
why does the driver still create /devices/pci0000:00/0000:00:1b.0/sound/card0/input4 for jack reporting ?
