HowTo Disable Sound Card
 

I have a ALi Corporation M5451 which is known as ALi 5451. I recently purchased a PCMCIA sound card to get better sound quality through a home theatre system. Anyways, I am running MEPIS 6.0 with all the kubuntu repsoitories..? Why? I had an issue with my wireless card and MEPIS was the only install out of the box that could recognize my wireless card. But as you know mepis is basically... Kubuntu. The problem is MEPIS recognizes both sound cards but boots the onboard as the default. I have looked up how to take care of this and the only thing i find is to disable it through bios, however i cannot do that on this particular notebook pc. Any idea?

Never used that distro but maybe rename the which sound card is defined first in /etc/modprobe.conf would do the trick.

I attempted to edit the /etc/modprobe.conf file but thhe file was empty?

Not sure what to do from here. The file might be called /etc/modules.conf

Brain

To force onboard sound to another sound card.
1) Note name of the module for on-board sound
2) Add "options [module name] index=X" in either /etc/modules.conf or /etc/modprobe.conf. Do not include quotes. X is the card number.

0 is first card
1 is second card
2 is third card
3 is fourth card

ok that may help, but sorry i am a newb, where do i find the module name?

Do you mean the module the hardware is using? First you can run the command ' lsmod ' to list loaded modules. Should have some releataion to snd* something. That may not be part of the name but close to it anyways. List the output if unsure. Since there may be two of them then maybe output of ' lspci ' and searching to find out which module the device may use.

If mean the location of module.conf or modprobe.conf then it is in /etc

Sound card.. run alsaconf it should detect both sound cards and ask you which one you want to use.. Once selected it will load the appropriate modules for you. follow the prompts..

Do not use alsaconf because it can screw up your configuration. Just type /sbin/lsmod and post the results.I or someone else can sort through the mess.

If you computer has USB, you can try to find Audiotrak Optoplay.

here is the complete output of /sbin/lsmod...

ok well i went out alimb and actually fixed the problem myself... using that output.... snd_ALI5154 i just blacklisted that driver in /etc/modprobe.d/blacklist and it automatically shut out the onboard audio.... excellent... thanks for your help
