How do I use emu10k1 instead of AC97

erpe · 08-23-2006, 07:51 AM

Here's what I did so far:

1 Disabeled AC97 in Bios
2 Configured emu10k with alsaconf

Unfortunatly after each reboot it sets AC97 as the default driver

Therefor I need to rerun alsaconf every time I reboot.

How do I remove the AC97 driver? Or how do I set emu10k as the default so that don't have to run alsaconf everytime? Thanks in advance for your help!

when you've run alsaconf and configured it just how you like, run

Code:

aslactl store

as root and it'll save your changes.

Thanks for the suggestion. I did 'alsactl store' after alsaconf. After reboot I had the same problem

You have to "blacklist" the ac97 sound module. I've forgotten exactly where the blacklist file is, but I'll figure it out later today, if you can't.

i don't really know what the problem is then, but it seems to me that this line in your dmesg output might be part of the problem:

Code:

PCI: enabled onboard AC97/MC97 devices

are you sure you've disabled the card in the BIOS? Also, what distro are you using? Might be worth checking what's being started up when you boot. In slackware I'd check the /etc/rc.d/ directory for the modules being loaded at boottime.

Sorry I couldn't be more help.

edit: ah, and then suddenly rickh's post appeared! sounds like he might know more than I do - follow his advice!

Lol thanks. Btw I am certain I have disabeled ac97 in the bios (checked it twice)

If you could help me with this, that would be great! I can imagine it has something to do with the /etc/modules file?!

Have you looked into the /etc/modprobe.d/sound and checked to see if the AC97 module is listed first there? If not try using something like this for the file.

Code:

alias snd-card-0 snd-emu10k1
options snd-emu10k1 index=0
alias snd-card-1 snd-via82xx
options snd-via82xx index=1

This should tell the system to always use the emu10k1 as the first sound device and the onboard as the second.

Here's my /etc/modprobe.d/sound:

Code:

alias snd-card-0 snd-emu10k1
options snd-emu10k1 index=0

I changed it to:

Code:

alias snd-card-0 snd-emu10k1
options snd-emu10k1 index=0
alias snd-card-1 snd-via82xx
options snd-via82xx index=1

Rebooted and it worked

Thank for the help

Your welcome BTW probably no need for reboot you could have used /etc/init.d/alsa reload to reload alsa with the new settings checking the results with a command like below to ensure the cards were detected in the proper order.

Code:

>$ cat /proc/asound/cards
 0 [Audigy         ]: Audigy - Audigy 1 [SB0090]
                      Audigy 1 [SB0090] (rev.3, serial:0x531102) at 0xe500, irq 16
 1 [V8237          ]: VIA8237 - VIA 8237
                      VIA 8237 with ALC658D at 0xd800, irq 17
 2 [Bt878          ]: Bt87x - Brooktree Bt878
                      Brooktree Bt878 at 0xfa024000, irq 20
