well, thats somewhat better.

note: a hint that you need to download alsa-kernel to compile alsa-driver from hg would be nice.

same behavior as 1.0.12, only, of course, more debugging is turned on in this version.

which means, i have sound, through the speakers, no headphone jack functioning, and no kernel oops.

the last output of loading the module reads as follows:

using the sound results in the following kernel messages, repeatedly.

Dec 28 18:57:15 faiserver kernel: ALSA /usr/src/hg/alsa-driver/pci/hda/hda_codec.c:216: hda_codec: invalid dep_range_val 0:7fff
until you close the sound, in which case you recieve the following:
Dec 28 18:57:28 faiserver kernel: hda-intel: Invalid position buffer, using LPIB read method instead.

so, this is a newer version, with the same functionality as 1.0.12, only now, it fills up my syslog. :P
no biggie. i use my laptop with headphones, so this is still "non-woring" as far as i'm concerned. i wont run out of diskspace playing sound. ;P

ask if you need any more debugging information.
