[alsa-devel] HDA or AC97 for Nvidia MCP61S?

[alsa-devel.20.pris at spamgourmet.com]

Hello,

as I already reported on another email I'm having problems with my sound:

http://thread.gmane.org/gmane.linux.alsa.devel/49412

My motherboard is PCCHIPS A13G+.
The sound hardware of my Mobo is in the NVIDIA MCP61S Single chipset.
This chipset consists of: GeForce(R) 6100 GPU and MCP nForce(R) 405
Codec: Realtek ALC660-VD

When looking at the soundcard matrix for Nvidia there are 2 options listed:

AC97 nForce-1 - nForce-4
HDA nForce-430 and later

Since my chipset is nForce 405 should I select the first option
AC97? But everyone seems to advise me to use the HDA option.

When I look at the details for HDA I see only "Intel HDA driver" and
nothing about which particular chipsets are supported.
On the AC97 option there is a list of chips but all are from Intel and
none from Nvidia.

So I'm confused. Which soundcard is the correct one for me? Is my
particular chipset supported at all?

Thanks!
