Did you test the newer slot method too? [rocketmouse@archlinux ~]$ cat /etc/modprobe.d/alsa-base.conf # ALSA module ordering options snd slots=snd_hdspm,snd_ice1712,snd_ice1712 "Problems with alsa.conf and udev On modern GNU/Linux systems, udev takes care of discovering hardware and loading/unloading Alsa. There is one drawback to udev. Udev will load Alsa modules in an undefined order. After each reboot or plugging/unplugging a device, there is no guarantee that a device is renamed using the same hw:x,y numbers. For example, if you have two USB devices on your systems, for example an Audeon USB and an Edirol UA-25, after each reboot, a card can be "hw:0,0" and the other "hw:1,0", each time randomly. /etc/init.d/alsasound is an udev wrapper that will take care of loading the ALSA modules during booting. But even with it, a few problems may still occurs. Reordering the driver for a particular card You can tell /etc/modprobe.d/alsa.conf (or alsa-base.conf, or similar) to keep a driver in out of the default slot. For example, if you have a a Creative Labs soundcard driven by the "emu10k1" driver and you don't want it to be your default card 0, append options snd slots=,snd-emu10k1 Note the comma in this line that moves the driver to the second slot. Module ordering problems It may be that the sound card order is wrong after booting, but running (as root) /etc/init.d/alsasound restart or /sbin/alsa force-reload gives the wanted card order. This can happen because udev is loading some sound driver before alsasound, and alsasound gets confused. A restart will first unload all the sound modules and when restarting, alsasound will work as expected. The solution is to blacklist the module(s) that udev is loading before alsasound (Typically, the one you get as sound card 0 after booting). You must do this into /etc/modprobe.d/blacklist.conf You must also report it as a bug to your distribution." - http://alsa.opensrc.org/MultipleCards#How_to_choose_a_particular_order_for_multiple_installed_cards ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
