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

[Valerio tesei]

This evening i will check out the Takashi sound-2.6 git kernel tree and
update it every day to give feedback on problems with this card on my
motherboard.

If i could help in any other way (debug, dmesg or others) let me know :)

why alsaconf does not find my card? what i'm wrong?

anyway, thanks for all this work.
