[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:


and enabled a module:


The kernal is 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

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