AC97 codec on asus k7m?

AC97 codec on asus k7m?

[buddy]

Is there any support for the 'AC97' codec on the Asus K7M athlon
motherboard?

I can't get it going, not even with OSS commercial...

Any suggestions are appreciated.

lspci shows that it is some kind of VIA chipset...

foobar:~$ /sbin/lspci

AC97 codec is not directly accessible. You should get specs for the chip
which is doing a bridge between codec and system bus.

AMD 751 Northbridge as expected

MVP4 ISA bridge

MVP4 Audio Codec

So it looks like the asus k7m is AMD 751 northbridge + VIA MVP4
southbridge. Yes it can be supported. I dont know if anyone has written
MVP4 audio support yet.

... which may supported by the VIA 82cxxx driver, in the later 2.2.x kernels.

Does anyone know about the status of the AC97 codec found in
Intel i810 chipset based mainboards like the supermicro 370SWD ones ?

X11 is supported by the Precision Insight drivers,
now what's missing is sound, since I want to use these boxes as
thin multimedia clients.

I remember that Alan Cox said on linux-kernel that enough
specs are available to write a driver, but I'm not aware of a
working driver. ( 4Front seems to support the i810 sound
in their commercial OSS)

Benno.
