note on Suse 10.3 build

[randall]

To all:

Had to rebuild the Suse 10.3 kernel again to get back the NVidia MCP61 
(RealTek ALC662) on board sound.  Turned on two SND parameters in the kernel 
config file:

CONFIG_SND_DEBUG=y
CONFIG_SND_DEBUG_DETECT=y

and enabled a module:

CONFIG_SND_SOC=m

The kernal is 2.6.22.18-0.2 x86_64 architecture.

The sound file under /etc/modprobe.d is

------------------- snip ----------------------
options snd-hda-intel enable=1 index=0 model=3stack-6ch-dig position_fix=1

# CvwD.9hpqWdunz16:MCP61 High Definition Audio
alias snd-card-0 snd-hda-intel
------------- end snippet -------------------

and the 3stack 6 channel SPIF digital setting for the model type works for the 
NVidia MCP61 setup.

There were NO changes to the modprobe.conf file.

Not sure why the kernel has to be rebuilt to restore the onboard sound, any 
ideas?  The 3 changes are the only ones I've made, when running menuconfig.

Motherboard is Elite Computer Systems (ECS) GF6100-M754 with NVidia 
GeForce6100/nForce 405 running the AMD Athlon 64 3200+ processor.

and hwinfo --sound

You did something wrong, if the changes you did are really only the
above ones.

Did you try alsa-driver-kmp package on openSUSE BS multimedia:audio
repo?

Yes, made no difference.

This morning I carefully built the kernel step-by-step and found that changing 
this parameter in config for the kernel enabled my Nvidia MCP61 sound card to 
work:

CONFIG_SND_SOC =m

Once I set this to module, and rebuilt, then I was able to successfully have 
sound working.

Good thing it's just a one parameter change.

This is really weird because ASoC has nothing to do with your sound
device.  Thus I highly suspect that it's just a coincidence,
especially if the hardware works just after recompiling the kernel.
In general, you don't have to rebuild the kernel at all.

Make sure the following before testing:

- You have no other snd* modules in the module path.
- You have no backup files or files with unknown extensions in
  /etc/modprobe.d/ directory.

For getting a clean state, try the following:

- Uninstall kernel*.rpm package first
- Remove /lib/modules/2.6.* directory
- Remove suspicious /etc/modprobe.d/* files
  Check "rpm -qf /etc/modprobe.d/*".  Some files like ipv6, sound and
  tv are created by YaST.  Remove all backup files there.
- Re-install kernel*.rpm package again
  Check /boot/grub/menu.lst just to be sure

Now, check /etc/modprobe.d/sound file and make sure that you have the
right options.  This is a very important point.  In doubt, show the
whole content of this file.

Then reboot.  Check /proc/asound/cards and see whether the right
device appears there at first.  If not, it's likely a problem of index
module option.
