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
...
...
I'm using it.
...
I must wait for a patch, hoping in Takashi? :)
...
I think i will make some experiment on patch_realtek.c :)
...
For the noise problem if i understand a little, could be a connection
...
problem, i will try to graph it.
...
For the capture problem i need to read more :)
...

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
...
...
...
...
Seems to be a common problem from 2.6.37 with 267.10 driver, for the
...
moment i will hope this does not create any problem.
...
I'm not using hdmi on Mobo neither the one on Video card.
...
...
...
...
...
...
...
...
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
...
...
...
...
This mean that tecnicaly my sound card/motherboard must work with the
...
patches that Takashi commited?
...
...
...
...
...
...
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.

why does the driver still create

Takashi if you need debug or something else just ask.
I put "more verbose debug" into my kernel config, I'm starting to describe
the issue:
my player is mplayer, I'm playing a divx by alsa output.
I tried the patch suggested by Raymond
   if (codec->vendor_id == 0x10ec0892)

           spec->stream_analog_alt_capture =

&alc880_pcm_analog_alt_capture;
Putted into sound/pci/hda/patch_realtek.c ,  function patch_acl662, but
nothing changed, issues are the same.
After module is loaded big noise starts, at first right channel is muted, I
hear realy disturbed and bass are crackly, after 10 minutes right channel
start crack, after 10 minutes, right channel is low but sounds, only bass
cracks, and high frequencies are clear.
Front-Panel is physicaly detached from motherboard, in bios is setted as
"AC97", and S/P-DIF is setted as S/P-DIF
New alsa-info are this:

your info is different from  hda-emu/codecs/alc892-asus-p7h55

                    AMP_IN_UNMUTE(1));
The noise may be due to umute of connection 0x0b in 0x0c, 0x0d, 0x0e and
0x0f by alc662_auto_set_output_and_unmute() since those input pins (e.g.
Front mic, line and rear mic)  's  "playback switch" in audio mixer 0x0b is
not muted by alc662_auto_init_analog_input() or alc662_auto_init_input_src()
http://www.intel.com/support/motherboards/desktop/sb/cs-020642.htm#multistre...
It depend on whether you want your voice record from front mic appear in
speakers connected to all rear panel jacks when ummute "front mic playback
switch" if you use it as karaoke or multistreaming playback
Do you get the correct sound from the rear panel and front HP when running
"speaker-test -c 8 -t wav -Dhw:0,0" ?
Two set of input sources,capture volume/switches since the number of
connections is different in node 0x22 and 0x23 as node 0x22 has the digital
