Hello,

I just bought a desktop PC with a GeForce6100SM-M mainboard whose
NVIDIA MCP61S chipset is "High Definition Audio Specification 1.0
compliant". I installed the latest stable Debian (2.6.18-6-486),
everything worked well so far... except that there is no sound.

alsaconf says "No supported PnP or PCI card found"

I added a line "alias snd-card-0 snd-hda-intel" to
/etc/modutils/alsa-base and ran update-modules (after reading
http://www.alsa-project.org/main/index.php/Matrix:Module-hda-intel), but
without result.


Here are some things I tried:

# /etc/init.d/alsa reload
Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).

# lspci | grep Audio
00:05.0 Audio device: nVidia Corporation MCP61 High
Definition Audio (rev 2a)

# lsmod|grep snd
# (no output)

There is no directory /proc/asound

I checked whether the normal user is in the audio group:
# groups milvi
# milvi : milvi dialout cdrom floppy audio video plugdev
netdev powerdev

I'd be glad if somebody can help me! I'm willing to learn and not really
new to Debian, but audio configuration seems complex.

Hi Luc. I've just recently built a new machine with an Asus M2N-X Plus mobo,
which has Geforce 6100, and MCP61 southbridge. I havn't got Etch installed
on, but sound is working ok with Kubuntu Gutsy Gibbon, Archlinux "Don't
Panic", and Fedora 8. One thing to check is that the Azalia codec is set to
"auto" in the BIOS, and not disabled.

It could also be that the alsa driver, alsa-utils, and alsa-lib arn't recent
enough on your Etch install. I've got Etch on a different machine, and no
problems with sound, but that's with an Audigy2 soundblaster card, but
according to cat /proc/asound/version the alsa driver is only 1.0.12rc1.

My Kubuntu GG install, where sound works has version 1.0.15 (still a bit old),
and that's with a 2.6.22-15-generic (SMP) kernel.

Just a couple of thoughts.

Nigel.

Hi :-)

I'm not sure, but I can try with module-assistant and compile alsa-drivers by
yourself and try again.

Do you have built-in sound /and/ a plug-in sound card? grep may have missed a
second device. Try using "lspci | grep audio" (lowercase "a") or inspecting the
full output of lspci [1].

Do you need to enable on-board sound in the BIOS?

If you have got an old sound card you could plug in, see whether alsaconf
detects that.

I believe that alsaconf used to have some problems in Etch. You could try
running the Lenny or Sid Debian Live CD to see whether up-to-date Debian
recognises your chip. [2]

I installed some time ago a MCP61 on etch. First time, it was not 'out of the
box', needed to had a line in alsa.conf. But later alsa drivers was updated
and the sound carte was installable with alsaconf without any problem. This
was about a year ago. So it should still work now. Sorry I can give more
explanation, I dont have that MB any longer. But it is at a friend place, and
I can eventually go there and have a look, but not today, maybe tomorrow....

I see two possible matches in pci.ids, device IDs 03e4 and 03f0. You can
check which one you have by using "-nn" with the lspci command:

lspci -nn | grep -i audio

You should see either [10de:03e4] or [10de:03f0]. (10de is the vendor ID
of nvidia.)

As far as I can tell, support for both these chipsets was added after
the 2.6.18 kernel was released, so you will need a newer kernel. Version
2.6.24 is available for Etch from backports.org; your sound should work
"out of the box" with this newer kernel. You can find details about
installing backports here:

Wow! Five helpful people answered to my problem! Before I posted this, I
had been searching the Internet and docs during many hours, and I felt
alone and frustrated... Thank you Nigel, Chris, Thierry, Pol and Florian.


My problem needed indeed "just" a kernel upgrade, here is the summary of
what I did:


# nano /etc/apt/sources.list
(then added the following line
deb http://www.backports.org/debian etch-backports main
contrib non-free
# aptitude install debian-backports-keyring
# aptitude upgrade
# aptitude install linux-image-2.6.25-2.486
# reboot

Is there no 2.6.25-2.686 flavour?

There is, and also a 686-bigmem, but until today I didn't really pay
attention to kernel flavours. Thanks for the observation.
