Subject: Realtek ALC650E support in 2.[45]?

Trying to get an upgrade and have a choice between two MBs. Both have
onboard sound and one has the ALC650 audio support and the other has
ALC650E audio support. I believe the former is s/w and the latter is
h/w. I'd like to get the ALC650E but I can't find any clear info if
there's support for it in either the 2.4 or 2.5 linux kernels. I found
mention of the ALC650 in the source but not the ALC650E. Searching
the web did not yeild much clarity either (and neither did the ALSA
website :/) but I may have missed something though.

Anyways, does it support it? I'd prefer fully OS driver support and
don't mind using patches but prefer to be able to compile the driver
into the kernel as I like the lack of messyness that comes with
monolithic kernels.

Any help would be truly appreciated. Thanks.

ALC650(E) is the AC97 codec chip. There must be an audio core in
addition, most likely Intel ICH chips or VIA 82xx chips. Both are
supported by ALSA, snd-intel8x0 and snd-via8xx drivers, respectively.
On OSS, they are i810_audio and via82cxxx_audio drivers.

ALC650E is a revision E of ALC650, which has some minor extensions
(like S/PDIF support) but mostly identical with ALC650.
So both should work.

Aha. Ok. What about with an Nvidia2 backend (MCP-T) to all this?

it's (almost) compatible with Intel ICH and works with the recent
intel driver above.

ALSA, right? What's in 2.5 or still outside of it? And if outside, soon
to be added?
