Package: linux-image-2.6.18-3-k7
Version: 2.6.18-7
Hi,
I have 2 sound cards, one on the mother board and one plugged in a PCI slot.
I disabled the on board card in the BIOS configuration because I want to
use the other one.
The kernel continues to see the on board card also after disabling it in
the BIOS!
Notice that it disappeared in Windows 2000 after disabling it.
The problem is that the on board card is loaded as default ALSA card,
but I have my speakers connected to the other card.
Add to this the fact that:
- changing the default card with 'alsaconfig' works only until you
reboot (then you have to rerun it)
- there is no simple way to choice the default card for ALSA in KDE Arts
- debian does not provide an interface to setup default audio card or to
disable unwanted hardware (don't load modules)
and you'll see that listen to music while browsing the web is a real
trouble!
If any of my previous statements are wrong, please correct me! I'd like
to solve my troubles...
My solution was (may be of help to other people): start XMMS, select the
audio card for the output plugin (the alsa plugin of XMMS shows the
available hardware by name!), copy the hardware string for alsa and
paste that string in the additional configuration of Arts in KDE.
Anyway the kernel should never activate BIOS-disabled hardware in my
opinion, at least not by default.
Some infos about my configuration (tell me if other things may be useful):
* Hardware
MB: ECS KT600-A
Chipset: VIA KT600 + VT8237
BIOS: Award (Phoenix) version 6.00 PG
On-Board Audio: ALC 655 (AC '97 2.3)
PCI Audio: Creative SoundBlaster Live!5.1
CPU: AMD Athlon XP 2200+
* Software
debian: testing (etch) - updated about once a week
kernel: linux-image-2.6.18-3-k7 (2.6.18-7)

reliance on bios is bad,
every bios out there is quite buggy.

just disable the loading of the onboard snd card modules,
blacklist them in /etc/modprobe.d, see blacklist in man modprobe.conf
also the kernel is not responsibe per se on loading modules,
this is userspace work. alsaconf is known buggy for more than
one sound card. i wouldn't rely to much on it.

closing bug report, as sound cards work as expected
and thus not a kernel problem.
please ask next time for guidance on the debian-user mailing list.
