[alsa-devel] HDA or AC97 for Nvidia MCP61S?
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: http://www.alsa-project.org/main/index.php/Matrix:Vendor-Nvidia
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!

They are correct. It's highly likely HD-audio only. Even though the controller supports AC97, it's useless if the device has no AC97 codec chip.
Nvidia, AMD and other controller chips are almost compatible with the first chip supported HD-audio, which was Intel.
So I'm confused. Which soundcard is the correct one for me? Is my particular chipset supported at all?
Yes and yes. It's no quesiton about the chipset but the hardware implementation in another level. Each mobo or laptop has slightly different designs even with the same chipset. This difference gives great pain for HD-audio driver.

Hi Takashi
Did you try my suggestion?
Not yet. I didn't try it because I'm not yet convinced that I need to install a new version in order to get it going. After all sound IS working with the example ogg file that comes with Ubuntu. Is this possible for the sound to work with one file and not work with another and this to be a problem with the ALSA driver? I thought maybe this is some configuration problem.
Again, I have no problem in recompiling the driver, I just wanted this to be the last step to try.
Thanks for your help!

A related question: is it safe to use the latest snapshot of the Alsa driver?

Yes Takashi,
I finally tried your suggestion.
To be more exact, I followed the instructions at the following address, using the newest driver version of course(1.0.15):
https://help.ubuntu.com/community/HdaIntelSoundHowto
So, I downloaded and installed 1.0.15 of alsa-driver, alsa-lib and alsa-utils.
I tried the following configurations in /etc/modprobe.d/alsa-base:
options snd-hda-intel model=3stack-660 options snd-hda-intel model=3stack-660-digout
Rebooted, no luck.
After that I installed the latest driver snapshot: alsa-driver-hg20071129 Note that in this case I didn't reinstall alsa-lib and alsa-utils but kept the 1.0.15 version that I had just installed.
Results: avi files play and I hear the music sound fine, but when people speak, it is all garbled and low volume. Again, the soundtrack works but not the talking.
Any help is appreciated!
