Did you upgrade the system ? Make sure you installed alsa 1.0.18 through the package system.
Then check your kernel documents and find the ALSA configuration guide. It should be somewhere like the below:
/usr/share/doc/kernel-doc-2.6.27/Documentation/sound/alsa/ALSA-Configuration.txt
Try to search ALC1200 in that documents. If there is some model available, modify your /etc/modprobe.conf and add a line like this:
Quote:
|
options snd-hda-intel model=#####
|
Replace ##### with the model you found. If one does not work, try another till the end.
Good luck~
