[alsa-devel] [PATCH ALSA HDA 1/1] Fix alc662_dac_nid and change 6stack-dig to 5stack-dig

[Valerio tesei]

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?

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.

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 ?


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.
