Hi Oleg,
Thank you for a tips
I tried to follow t your tips with no result.
First, kernel documentation HD-AUDIO-models.txt is not up to date because
kernel 2.6.36 knows this ALC892 model. (/sound/pci/hda/patch_realtek.c)
But all my attempts to select model as modprobe option for snd_hda_intel
fiailed, and the delegating to bios did not help.
So I do not have sound in 2.6.36 and even in 2.6.37-rc6 - no sound at ALL !

Hi,
My system Asus P7HP55M Pro board +i3 530 processor running Ubuntu 10.04, 10.10
Board had HDMI port to output video and audio.
Video is OK, cabel is ok because it is HDMI 1.4 (suppors audio )
I have issues with sound :
alsamixer under the kernel 2.6.32.26 shows only line in, mic and SPDIF output
aplay shows hdmi subdevice
Sanity check: try different mixer (starting with alsamixer) and volume
control applications and see if there are any controls missing from
the GUI (usually somewhere under Preferences) and volume set to 0.
In the past I found that something like gnome-control-volume or
gst-mixer could be used to switch the right channel on, even though I
used KDE. I have no idea why. In my experience the issue was typically
microphone not working for Skype and such.
I have a lot of controls: line, headphone, front, rear, surround,
SPDIF1, SPDIIF2, ...
-indeed the board has it.
I expected to see some control labeled HDMI, but may be I am wrong
I migrated to Ubuntu 10.10 to have a latest alsa version . Now alsamixer thinks
it works with Intel IbexPeak HDMI chip, sound from line out gone.
Not only HDMI this time?
I put a custom kernel (vanilla 2.6.36.2) hoping for the best but
still no sound.
aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC892 Analog [ALC892 Analog]
Hmm... I have a 2.6.33 kernel lying around on my work laptop, and I
don't see ALC892 in Documentation/sound/alsa/HD-Audio-Models.txt. I
don't know if it is significant, nor do I know whether, say,
ALC882/883/885/888/889 is a good substitute. It probably is, and in
any case I understand that you have sound, just not through HDMI. This
probably means that what follows is not the solution, but if you have
no other ideas you might want to try your options.
Check your /etc/modprobe.d/alsa-base.conf (or whatever the Ubuntu
equivalent is) against "lspci | grep Audio" to see if the model
specified looks right. If you decide to play with the model then you
may try the following:
1) choose the default "auto" model, in this case the kernel relies on
the BIOS, and this means that the sound device should be enabled in
the BIOS - check that.
I did it
2) disable the sound card in the BIOS, boot, choose this or that model
that looks relevant from the HD-Audio-Models.txt list, and reload the
module/modules.
I tried, but no matter what I wrote in alsa-base.conf I got no sound
Just some random ideas...
