[gentoo-user] (AMD64) wrong soundcard is becoming default - Gnome unhappy

[Mark Knecht <markknecht@gmail.com>]

Hi,
   In my previous Athlon XP I was using two sound cards - an AP2496
and an RME HDSP 9652. I had /etc/modules.d/alsa set up so that the
AP2496 was the default card and the HDSP wa used only when I
specifically called it.

   On my new AMD64 machine I wanted to do much the same thing except
I'm using the onboard sound as well as an RME HDSP 9652. Unfortunately
for some reason it seems that the HDSP 9652 is being made default and
this is not making Gnome happy:

lightning ~ # cat /proc/asound/cards
0 [CK804          ]: NFORCE - NVidia CK804
                     NVidia CK804 with ALC850 at 0xda103000, irq 185
1 [default        ]: H-DSP - Hammerfall DSP
                     RME Hammerfall HDSP 9652 at 0xda000000, irq 209

Here's /etc/modules/alsa. Note that I do not want OSS emulation for
the HDSP 9652 so that portion is set up only for the NVidia sound.
This worked for the AP2496/HDSP combo:

# Alsa 0.9.X kernel modules' configuration file.

alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

# Set this to the correct number of cards.
options snd cards_limit=2

   After editing this file I run modules-update and then either
/etc/init.d/alsasound restart or do a reboot. In both cases, on this
machine, Gnome sees no sound card since it's using OSS emulation and
(apparently) pointing at the HDSP.

   How can I get Alsa to point at the NVidia chip as far as Gnome is concerned?

NOTE: alsamixer works and goes to the NVidia chip. alsactl store seems
to store good info.
