[alsa-devel] note on Suse 10.3 build
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.

Again, any ideas as to why the kernel has to be regenerated to enable on-board 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.
