[Alsa-user] soundcard order changes on reboot

2009-01-13 Thread Guenther Meyer 
hi,

I have a system with two soundcards (nvidia onboard, maudio 1010) running 
debian lenny.

sometimes after a system reboot the order of the devices changes:
one time nvidia is card 0 and maudio is card 1,
another time nvidia is card 1 and maudio is card 0.
that's not good, because all the routing could go to the wrong card,
and adapting asound.conf every time is not really a good solution.

so is there a way to fix the devices to specific numbers?

That sounds like udev doing it's usual trick of loading everything 
simultaneously, resulting in it being anybodies guess in which order multiple 
cards, whether sound, ethernet, video, etc, will be loaded.

The sound is easy to fix, by setting options lines 
in /etc/modprobe.d/alsa-base. Example below.

options snd-hda-intel index=0
options snd-emu10k1 index=1

Just change the driver names above to yours, and in which order you want them 
to be loaded.

All the best.

Nigel.

Hey 

I have the same problem but with multiple MIDI devices that use snd-usb-audio (evolution uc-17, bcf-200, amt8),is there a way to set the order with multiple cards that use the same module? 

cheers

Allan

Hi Allan.

That's quite easy, but I've lost the email with the specific instructions. You 
will need the vendor id's, and product id's for each of your usb devices, but 
lsusb should provide you with those.

As I say I forget the exact lines that you need to set, so post a message to 
the list, with the subject line as below.

How to order multiple usb devices

Just a suggestion, but please post your messages in plain text, not HTML, and 
post your replies at the bottom of any replies you receive.

Hoping that you resolve your problem.

Nigel.
