Takashi,
Thanks, I'll work on getting this upgraded and post results. Some things I noticed while looking over patch-realtek.c:
1) There is no enum defining the different NID values. The hex values are used all over the code and you always have to keep referring back to the list. Would a patch be accepted to convert the hex values to a proper enum? It makes the code more clear to someone who hasn't looked at the chipset datasheet before. I see the complete list in the ALC883 datasheet, but I'm not sure if it is specific to the ALC883 or if it is defined by each HDA spec revision.
2) There does not appear to be an ALC883 profile which sets all available NIDs to output. In my case, I am attempting to get as many stereo outputs as possible from the chipset and I do not care at all about capturing audio. The 6stack profile does not set the pin configurations for the MIC1/2 and LINE1/2 NIDs. Would a new model be required if I want to attempt to configure all possible NIDs for output? Should this be called "all-out"?
3) I noticed a few discrepancies with the hda header files and the ALC883 documentation in regards to bits being checked for a few values. I'll follow up with those once I'm back in front of the code.

Hello everyone,
I'm currently trying to get the ALC883 on the Albatron KI690-AM2 motherboard working under ALSA and I'm running into problems with some of the ports. From looking at the patch_realtek.c file inside the intel_hda driver, it appears there are many variants of hookups to this chipset which all require some manual configuration in the driver. I've tried what appears to be the closest match (ALC883_6ST_DIG or 6stack-dig), but it still does not enable all of the ports.
The motherboard webpage is here: http://www.albatron.com.tw/English/product/mb/pro_detail.asp?rlink=Specifica...
The board has two audio stacks on the back panel. Facing the jack inputs, the left-hand stack contains: <S/PDIF output> <TOSLINK w/ green cover>
Next to that stack is a larger 6-stack with the following configuration: <blue> <black> <green> <pink> <grey> <TOSLINK w/ pink cover>
The box is running a stock debian 2.6.18-4-486 kernel.
First of all, try the very latest ALSA version (from HG repo) if you want to debug HD-audio stuff. It's the most actively changed part in ALSA drivers. 2.6.18 is way too old as a reference. Also you should build the driver with debug option (in the case of alsa-driver tree, pass --with-debug=full to configure).
If the latest version still doesn't work (with all available models), then check /proc/asound/card0/codec#* files.
(Anyway, I'll be on vacation from tomorrow, so cannot work on your problem. Hopefully this will interest other guys...)
