You don't say what Debian version you're using, but my 3 Debian installs were initially, Debian 3.0r2 (Woody) which I upgraded online to Sarge from the testing repo. (Sarge was testing at that time). One of my installs is now still on the testing repo, so is gradually upgrading to Etch. Looking at one of the Sarge installs, now on stable repo, I see no problems with card details in /etc/modutils/sound . It looks like this at the moment. alias snd-card-0 snd-emu10k1 (Audigy2 soundblaster card) options snd-emu10k1 index=0 alias snd-card-1 snd-usb-audio options snd-usb-audio index=1 The last two lines I added, as my usb-midi-keyboard was being detected as a sound card. (usb is picked up very early in the boot process) Just run update-modules after making the additions, and they are still there. You probably are aware of this, but running update-modules after making additions to /etc/modutils, updates the file /etc/modules.conf . I've just booted up the Debian/Etch install, and that too shows no missing files. Incidentally all my Distros running music apps, run on the same machine. Unless you're on Debian Sid (sailing close to the wind) and some update has removed files. I don't have Sid so could not help if that's what you're using. What does cat /proc/asound/cards show as to detected soundcards? Does it show you're usb one as being detected. All the best. Nigel.
