[linux-audio-user] Multiple sound interfaces, ALSA order detection

Hi everyone, I'm sorry if this has been dealt with before but I can't seem to find anything about it... I have two sound interfaces in my Debian unstable PC box: one being the motherboard (ASUS P4P800SE) chipset's (Intel ICH5) and the other a M Audio Delta 66. I want to be able to use both, the internal for mp3 playback/plain music listening and the Delta for music making (mainly Pure Data). I created aliases for the interfaces (in /etc/asound.conf) as indicated in Alsa's website docs: pcm.!default { type hw card 0 } ctl.!default { type hw card 0 } pcm.ICH5 { type hw card 1 device 0 } pcm.Delta66 { type hw card 0 device 0 } The remaining problem is that everytime I reboot, the order of the hw:0 and hw:1 is sometimes swapped i.e. one day hw:0 will be the ICH5 and the next day could be that the Delta is detected as hw:0. What do I have to do so that one order is preserved upon reboot/re-detection of the interfaces? ++ Jé
