no sound with HDA intel on ICH7 chip (AD198x)

Hello everyone,
I seem to have problems with sound on a ICH7 chip. the motherboard is an ASUS P5LD2-SE

The kernel is custom, but SND_HDA_* is included. and generally the sound device is identified properly.

here is some relevant output of aplay -l and -L, lsmod and relevant part of lspci -vv

root@halki:/temp/root/support# aplay -l

I read this relevant thread:

but my GPU doesn't have an HDMI output (and no sound module either). Note that I did see a similar msg
"No state is present for card NVidia
Unknown hardware: "HDA-Intel" "Nvidia GPU 0a HDMI/DP" "HDA:10de00a,10de0101,00100100" "0x19da" "0x6132"
Hardware is initialized using a guess method
No state is present for card NVidia"
to this one (of course it didn't include any nvidia references) but after running alsaconf, alsamixer, alsactl store once the msg vanished.

this thread didn't help either
as I'm running slackware64 13.1 on this pc and there are no newer alsa* package versions for me to install than the ones I already have.

Any clues where I can take it from here?
thank you for your help.

Try creating a file /etc/modprobe.d/snd-hda-intel.conf containing this line
options snd-hda-intel index=0 model=3stack position_fix=0 single_cmd=0
Googling "alsa asus p5ld2-se AD198x" showed these:

nope no luck

I wonder if there is a buffer mismatch and the playback buffer ends up reading from a different location..
because I really dont have any error msg popping up anywhere. mpg321 will play an mp3 no problem. (as in play but I won't listen to it)
and,no, i haven't plugged the speakers at the wrong jack
