First of all, use HG version if you want to debug the problem. 1.0.16 is already too old and sticking with this version makes a lot of problems (e.g. hitting the bugs that have been already fixed). Looking at your alsa-info output, the Master volume isn't set to the maximum. But, I guess it doesn't matter (not loud enough) even with the max Master volume, right? And, the question is about the headphone output or the speaker, or both? I see no obvious problem in the codec setup. One thing we can try is to change the connection of output pins directly from the DAC. Use hda-verb program to do this kind of thing without changing the driver code: ftp://ftp.suse.com/pub/people/tiwai/misc/hda-verb-0.2.tar.bz2 After compiling it, run as root like # ./hda-verb /dev/snd/hwC0D0 0x06 SET_CONN 0 and see /proc/asound/card0/codec#0 whether the connection of the widget 0x05 is changed to the first one (pointing 0x03).
