I have seen that after a kernel upgrade on F7. 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.
