I have a strange problem with alsa on Ubuntu Gutsy. If I compile and install the Alsa 1.0.14 driver, my sound card is not detected, and sound doesn't work. I also get the following message in dmesg:
[ 33.360190] stac92xx_auto_fill_dac_nids: No available DAC for pin 0x15
So the problem seems to be in the stac92xx_auto_fill_dac_nids function. When I copy that function from alsa 1.0.13 into the 1.0.14 source, everything works okay...
It looks like the function is rewritten for version 1.0.14, but for me it does not work anymore. I have to do the above steps with each new kernel update in Ubuntu Gutsy... Therefore I would like to fix it, but I don't know where to start.
Attach the contents of /proc/asound/card0/codec#* for further analysis. Also, check the earlier kernel message, especially the auto-pin configuration (make sure that you build the driver with --with-debug=full option).
thanks,
