Hi

I would like to help (or at least help myself) with the creation of a model config for alc889. I'm not a sound developer.

I'm using a laptop with alc889 based sound card. The reported pins are really messed up (it's hard not to use more profane expression). My laptop is Fujitsu-Siemens Amilo xi but the problems are the same as here: https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/71205 or here: http://mailman.alsa-project.org/pipermail/alsa-devel/2008-October/011295.htm... namely: 1.- no jack sensing (extremely annoying - for two years allready) 2.- misnamed mixers in volume control for gnome or alsamixer (example: front instead of headphone)

This is rather the mismatched pin configuration.

3.- the volume-control potentiometer on the side of the laptop is not

working

It depends on the hardware implementation. If it's connected to a volume-knob widget, you'll have a chance to get the notification and the value via an unsolicited event.

4.- I need to mute two different channel at the same time (center and

LFE) to mute one physical output (build-in sub-woofer) 5.- A great deal of other small annoyances destroying the user experience

Can you check whether this still applies (also explicitly with model=auto) with the very latest alsa-driver snapshot below? ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz

If it doesn't work, please run alsa-info.sh with --no-upload, and post the generated file to here (better add me to Cc). I don't want to dig into Web just to get any alsa-info.sh data...

I'm using model 3stack-dig and the optical output is working (at least is lighted up - I do not have the hardware to check it)

My questions are: - What I need to do, to create new model option based on 3stack-dig with different pin mapping?

Don't use 3stack model if you want the jack plugging. The [36]stack models are designed for static pins without any jack sensing.

- Is it possible that my present configuration (3stack-dig) is using

pins that should not be used? I'm asking in search of an explanation of problem 4. - What I need to do to rename the controls in alsamixer? - What to do to repair jack sensing? - that's the most important of all - What to do to repair the potentiometer for volume control?

I have seen that hda-analyser can create diff files, but where should they be used. (And why is hda-analyser not working - I was forced to use http://ubuntuforums.org/showpost.php?p=7227626&postcount=33. Is it that much to expect working tools on the official website. I understand that small bug will always exist, but that one is there for at least 10 months)

Ah, that's because I don't use that program by myself. I usually use the plain hda-verb and hda-emu, but not hda-analyzer. If you have a patch, I'm going to apply.

I won't be surprised if many of my questions are answered in the documentation, but I was unable to find anything useful. It would be enough to point me a place to start reading.

Read the HD-audio specification deeply first of all. Debugging the HD-audio stuff needs the knowledge of HD-audio design. Then, check Documentation/sound/alsa/HD-Audio.txt. It describes briefly the Linux driver internals.

thanks,
