Need help disabling sound card modules

[timberwolf753]

I have a problem, I have a a motherboard with built-in sound. It is a via-8235 something or other sound car built in to it. I also have a C-Media 8738 PCI sound card. The problem is i have the on-board disable but Kubuntu still see it and loads the modules for it. How do I disable the snd_via modules from loading. I manges to grep anything with snd_ via: see below.

snd_via82xx 29208 1
snd_via82xx_modem 16008 0
snd_ac97_codec 98336 2 snd_via82xx,snd_via82xx_modem
gameport 16520 2 snd_via82xx,snd_cmipci
snd_pcm 79876 5 snd_via82xx,snd_via82xx_modem,snd_cmipci,snd_ac97_ codec,snd_pcm_oss
snd_mpu401_uart 9472 2 snd_via82xx,snd_cmipci
snd 54020 19 snd_via82xx,snd_via82xx_modem,snd_cmipci,snd_ac97_ codec,snd_pcm_oss,snd_opl3_lib,snd_mixer_oss,snd_h wdep,snd_pcm,snd_mpu401_uart,snd_seq_oss,snd_rawmi di,snd_seq,snd_timer,snd_seq_device

Re: Need help disabling sound card modules

I would disable the on-board sound card in the bios. Usually hitting del of f2 when you see your bios splash screen will bring up the menu.

I am sorry as it also is disabled in the bios.

Before you try and disable those modules, try going into System Settings > Sound System and poking around in there.

If there's nothing there, try adding the modules' names to the module blacklist.

I loked and ther is no thing to mark the cmedia as the defult. How do I black list the modules.

How do I black list the modules.

Edit the file /etc/modprobe.d/blacklist (in root mode, e.g. by kdesu kwrite) and add the modules in question, one at a time (read: line), with "blacklist" as leading term, e.g.

blacklist snd_via82xx
blacklist snd_ac97_codec

You may, however, prior to that verify your approach by temporarily removing the modules in question, by the console command rmmod [module], e.g.

rmmod snd_via82xx

Heh, I was kind of hoping somebody would know exactly what to do... I didn't want to tell you to go around making kernel module-level changes when I don't even know what it'll do myself.

Don't panic - the kernel will do that for you as appropriate
