ALSA issue

[korgull]

Hi,

After upgrading from FC6 to f7, my onboard soundcard (which is switched off in 
the BIOS) is detected by the kernel and the modules are loaded.
By itself not an issue, but the onboard card is now the default.

How can make sure that the modules for the onboard card are not loaded ?

regards,
Marcel

If you are running Gnome, System -> Administration -> Soundcard
Detection.

Click on the Settings tab, and select the correct Default audio card.

I believe you can blacklist the modules by adding them to 
/etc/modprobe.d/blacklist

blacklist module_name

I've set it via system-config-soundcard, but still having issues :
xine plays sound well
mythtv and xmms don't but I have no clue why yet.

Thanks,

Well, added "blacklist snd_via82xx" but it still gets loaded.
Too bad that upgrades frequently break things.

If I don't find another solution I will downgrade my kernel to 2.6.19 which 
worked well for me (2.6.20 in FC6 also had issues for me).

Thanks,
Marcel

another way to kill modules from getting installed is to add to
/etc/modprobe.conf

install snd_via82xx /bin/true

... just a late thought, on disk these modules are called snd-* not
snd_*.  For some reason once the module is inserted it is reported with
- changed to _.  Therefore you may need to talk about snd-via82xx in
/etc/modprobe.conf since that is the name of the module file itself.
