For that you need to specify Vendor and/or product ids and also the "index" option to tell snd-usb-audio, which device you be at which card position. Here's some old info I found, which you could try: http://www.geocrawler.com/mail/msg_raw.php3?msg_id=10163242 There are some errors in your config as well. > alias char-major-116 snd > alias char-major-14 soundcore > > # i810 > alias sound-service-0-0 snd-mixer-oss > alias sound-service-0-1 snd-seq-oss > alias sound-service-0-3 snd-pcm-oss > alias sound-service-0-8 snd-seq-oss > alias sound-service-0-12 snd-pcm-oss > alias snd-card-0 snd-intel8x0 > alias sound-slot-0 snd-card-0 > > # ua-1a > alias sound-service-1-0 snd-mixer-oss You don't need the following line: > alias sound-service-1-1 snd-seq-oss Just delete it. > alias sound-service-1-3 snd-pcm-oss > alias sound-service-1-8 snd-seq-oss > alias sound-service-1-12 snd-pcm-oss > alias snd-card-1 snd-usb-audio > alias sound-slot-1 snd-card-1 > > # virtual midi 1 > alias snd-card-2 snd-virmidi > alias sound-slot-2 snd-card-2 > > # virtual midi 2 > alias snd-card-3 snd-virmidi > alias sound-slot-3 snd-card-3 > > #evolution 1 > alias snd-card-4 snd-usb-midi There is no snd-usb-midi module anymore. You need to use snd-usb-audio, but you already loaded that above, so you need that "vid"-trick, that should be explained somewhere in the archives. This is from the INSTALL file: Module snd-usb-audio.o ---------------------- Module for USB audio and USB MIDI devices. vid - Vendor ID for the device (optional) pid - Product ID for the device (optional) This would configure one slecial USB device as the second card (index=1): options snd-usb-audio vid=0x763 pid=0x1001 index=1 And I found this on the net for configuring two usb cards with fixed indexes: options snd-usb-audio index=1,2 vid=0x0763,0x0582 pid=0x1110,0x0005 > alias sound-slot-5 snd-card-5 > > #evolution 2 > alias snd-card-5 snd-usb-midi See above. Same error. > alias sound-slot-5 snd-card-5 Ciao -- Frank Barknecht _ ______footils.org__
