Your fixes are implemented in another way, so it should work as it is on 2.6.23 once after alsa.git is merged -- except for (obviously annoying-for-some-people) "unknown model" message. I'd say, simply ignore it ;) It's no bug. > Though AFAIK, ALSA maintainers have plans to move most of the > probing code to userspace somehow so I'm not sure if it is > quite relevant. Yeah, we'd like to go in that way, but it gets stucked right now, mainly due to lack of development time. A proto-type is availabe at ftp://ftp.suse.com/pub/people/tiwai/hda-tools/ but not sure whether this development will be continued to the final form or choose another method. thanks, Takashi
