Try the snapshot tarballs or git at
http://www.kernel.org/pub/linux/kernel/people/tiwai/docs/HD-Audio.html
Sorry, I've never build modules out of 'regular' kernel build process before, so I'd have a few questions. I'm using a tarball kernel source for kernel 2.6.38.2 taken from kernel.org, patched with some stuff required by my distro (therein aufs) and incremented to version 2.6.38.3 with the incremental patch taken, again, from kernel.org; I have no git version of the kernel to pull the alsa git snapshot over, and am not using a 'real' broadband connection at the moment, so I'd prefer not to download a full git source. For accomplishing your request, I've downloaded tarball alsa-driver-20110508.tar.bz2 from the ftp pointed to within the document linked above
Now my questions. In file 'SUPPORTED_KERNELS' I can read the following:
"The alsa-drivers in this package are designed for the following kernels:
- Vanilla 2.6.29 or earlier - Vanilla 2.4.31 or earlier - Vanilla 2.2.26 or earlier
It's not guaranteed that they work with any newer version than above or modified kernels by distributors."
Is it a harmless warning, or should I upgrade my kernel to version 2.6.38.4 or 38.5 and test the embedded alsa version (more recent than current one I'm using) instead?
I've modified, through menuconfig ( CONFIG_LOCALVERSION ), my kernel version string, so I can modify configuration at whim and keep different flavors of the same kernel version (though I'm using just one flavor for k 2.6.38.3); moreover, kernel source path doesn't match the exact 'name' of the kernel (as named in /lib/modules/<version>) and is located out of /usr/src, though actual source path is symlinked from within kernel install dir as standard 'source' subdir (pointing to <path/to/linux-2.6.33.2>). Hence, for what I've understood from file 'INSTALL' in ALSA snapshot tarball, kernel version and source tree should be easily identified by configure script, however, in case there is a risk that ALSA snapshot gets misconfigured I prefer to ask if I'd better to explicitly pass in --with-kernel and --with-build options.
But my main concern is about overall configuration. For better comparison, I'd wish to use the very same sound configuration I've used in kernel build process, but that's unclear to me if configure script for ALSA snapshot will retrieve and use it, or if the script can just use configuration options passed in/default values (as a 'regular' configure script).
Lastly, do I need to enable debug? (that is, is it required for better alsa-info output?)
For now, below I'm posting alsa-info.sh output for current configuration and for kernel 2.6.33.2 (with working sound), hoping this can help for comparison.

What is the model of your computer (desktop/notebook) ?
Sorry I didn't make it more clear in my previous post. Mine is a home-build desktop with an Asrock motherboard (I don't know of any notebook with asrock MoBo), model '890GX Extreme3', with integrated graphics (Radeon HD4290) and audio (via vt2020 codec and ati hdmi), NB AMD 890GX, SB850; CPU is a Phenom II X4 (kernel 2.6.38.3 is configured with amd specific optimizations while retaining x86 compatibility code; kernel 2.6.33.2 has no cpu-related optimization enabled; both are 32 bit); 4 GB ddr3 memory; no expansion cards.
If more details are needed, I'll write full specs.
How many audio jacks ?
Rear panel: 5 jacks for 7.1 channels audio + 1 Optical SPDIF OUT port On board: front panel audio header for ac97/hd audio (connectors for mic, left, right - I'm not sure if that's for supporting 2 independent mono jacks, one stereo (headset) jack or both cases, I don't know neither ac97, nor hd audio specifications) + header for 1 hdmi_spdif out (to be connected to a discrete vga with hdmi capabilities)
