you need to find the module the sound card is using that you DO NOT want to
load, and black list it.
lsmod will give you a full list of modules you are running, piping it to grep
will give you searching abilities. However, running the following as root
will give you a text file to look through:
lsmod > /root/modulesrunning.txt
view that file in an editor like kedit, kate, vi or less whatever you like,
and look for modules that have a name like the brand of card, or "snd" around
For example "lsmod | grep snd" produced the following on my dell:
snd_hda_intel 20116 1
snd_hda_codec 164608 1 snd_hda_intel
snd_pcm_oss 47360 0
snd_mixer_oss 19584 1 snd_pcm_oss
snd_pcm 84612 3 snd_hda_intel,snd_hda_codec,snd_pcm_oss
snd_timer 25348 1 snd_pcm
snd 58372 8
soundcore 11232 1 snd
snd_page_alloc 11400 2 snd_hda_intel,snd_pcm
From the looks of it I'd say "snd_hda_intel" is the module that's driving my
HD sound card.
(the column on the far left is the module or driver, the list of modules after
the two number columns is the list of modules the module on the far left
depends on. I can't remember what the two number columns mean at the
the module for SB Live! cards I believe (I may be wrong) has "live" in the
name. Anyway, once you find out what module you do not want to have loaded,
go to /etc/modprobe.d/ and edit the "blacklist" file like so:
and add a line that starts with "blacklist" has a space and then the module
name you DO NOT want to have loaded.
Reboot and see what happens.
You can also check kmix to see what "Master Channel" its using. Right click
on the little speaker icon in the system tray, and click on "Select Master
Channel" if you have more than one sound card, like when you have a voice
modem and a sound card, select the sound card module from the list and click
Hope some of this helps.
