ok, … 32-bit openSUSE-11.0 with 2.6.25.18-0.2-pae kernel with a Codec: SigmaTel STAC9271D
First, I note this in your mixer:
!!-------Mixer controls for card 0 [Intel]

Mono: Playback [on]Your levels are far from the 95% test levels I suggested. PCM is way way too low. I recommend you 1st get your sound working, then back off to a volume level where there is no distortion. Plus I highlighted in orange some settings that I do not understand. Perhaps you could explain your plan there?
Next, I note your PC has a SigmaTel STAC9271D hardware audio codec. The ALSA-Configuration.txt file has this entry list regarding that codec:
STAC9227/9228/9229/927x
ref Reference board
3stack D965 3stack
5stack D965 5stack + SPDIF
dell-3stack Dell Dimension E520
From a previous post, your /etc/modprobe.d/sound file is:
options snd slots=snd-hda-intel
# u1Nb.zg+CO3ggc1E:82801H (ICH8 Family) HD Audio Controller
alias snd-card-0 snd-hda-intel
you could try changing that to:
options snd slots=snd-hda-intel
options snd-hda-intel model=3stack
# u1Nb.zg+CO3ggc1E:82801H (ICH8 Family) HD Audio Controller
alias snd-card-0 snd-hda-intel
and then restart your audio with: su -c ‘rcalsasound restart’ enter root password when prompted, and restart your mixer, and test your sound.
When testing your sound, I recommend you copy this into a konsole:speaker-test -c2 -l5 -twav
and you should hear a ladies voice saying ‘FRONT LEFT’, ‘FRONT RIGHT’ five times.
If that does not work, change “3stack” with another entry from the list I provided above (for example switch ‘3stack’ with ‘5stack’ ) and restart alsa and restart your mixer and test your sound. If not sound try same again one at a time with dell-3stack and ref.
If that does not work, then may an update of alsa is needed. I can provide specific commands for that.
