[Solved] Help, if you have Asus V2S - Alsa sound working

[jasn]

I've got an Asus V2S, cousin to my Asus V1S, and I cannot get alsa sound to work no matter what I do. I have it working perfectly on the V1S, and sound on Windows XP works fine on both laptops. The recommended alsa config file option setting of model=lenovo from one working linux config, doesn't work for me. Although after reading through bunches of stuff, it seems that the proper setting for the Realtek 660VD codec in both the V1S and V2S is, either 3stack-660 or 3-stack-660-digout. After testing all three with the V1S, and seeing that they all work, I decided to stick with 3-stack-660-digout.

However with the V2S, it's the similar problem to what others have reported; modules build and load fine; no error messages; just no sound output. That would suggest something to do with output lines and headphone jacks, but I've tried plugging headphones into every port on the laptop, both while docked and undocked; checking and unchecking the headphone and IEC958 options in the Volume Control many times; all without any effect. I'm kind of at my wit's end, so I'm hoping that someone who actually has this working on a V2S, can share with me the entire contents of their /etc/modules.d/alsa file. Also if you can let me know what alsa-driver, (I've tried 1.0.15 and the Gentoo 9999 versions), and kernel version, (I'm on 2.6.23-r5), along with what BIOS version you are running (I tried downgrading from 300 to 206, which didn't change anything).

Well I finally got it to work by trying every combination I could think of. Finally here's the combination that worked;

Kernel source = gentoo-sources-2.6.23-r5
Alsa driver = in-kernel alsa sources (not alsa-driver!). Just select Intel HDA driver under the appropriate kernel configuration menu.
/etc/modules.d/alsa configuration = options snd-hda-intel model=lenovo

Just like the Gentoo wiki indicates. (Although I couldn't get it work at all with the external alsa-driver). When I tried the alsa-documentation recommended models for this codec, 3stack-660 and 3stack-660-digout, I got no sound. When I changed it to lenovo, everything worked.

What's strange is that with my V1S I can use asus, lenovo or either of the 3stack-660 model configurations, and sound works, (sort of). I'm kind of suspicious that the sound would work with NO model configuration information too, although I didn't try it. I have stuck with 3stack-660-digout based on the alsa docs, and while I do have sound output from both the speakers and the headphone/external jack on the laptop (not on the docking station though), plugging in my desktop speakers, or headphones, into the headphone jack, does not mute the laptop speakers. On the V2S, once I was using the in-kernel alsa and configuring it with model=lenovo, using the laptop external speaker port (but again NOT the docking station sound port), for headphones or speakers, DOES mute the laptop speakers. Both systems do not save the volume setting when rebooting though, (always muted on reboots), so it's a mixed bag.

Anyway I was looking for an excuse to revert the in-kernel alsa sources, and I guess this is a good a time as any.. I've reconfigured the V1S to use the in-kernel alsa and to use model=lenovo, and it works just like it did before with using the alsa-driver. I get sound output but no laptop speaker muting when plugging in external speakers. <sigh>.. [sarcasm/]Well it's not like these laptops are that identical anyway.[/sarcasm] They do have different webcams (linux-uvc for V2S, and stk11xx for V1S). At least they have the same bluetooth and WiFi. In case anyone wants to compare, here's my /etc/modules.d/alsa for both laptops;
