It appears to be a return of old problem that was on earlier Fedora versions. Try creating the following lines in /etc/modprobe.conf, then run depmod -a as root, then reboot. alias snd-card-1 snd-usb-audio options snd-usb-audio index=1 The USB is started early in the boot process, and the problem I always had with my usb midi keyboard connected, was that the keyboard would be set as card0, and the soundcard as card1, but in the case of FC1,2, and 3 the soundcard also showed up when running. cat /proc/asound/cards The problem appeared to be resolved with FC5, and FC6, and no extra entries were required in /etc/modprobe.conf, but apparently has returned. I run a bunch of distro's, but IIRC the problem returned after a kernel upgrade on F7, and adding the lines that I mention above have resolved the problem once again. Nigel. btw. What's the usb device you have plugged in when you boot? As a test unplug it before adding the lines to /etc/modprobe.conf, and boot without it. When booted up, plug it back in again. You should now see both cards when doing a. cat /proc/asound/cards.
