Description of problem:
As noted on the alsa docs for usb audio devices:
http://www.alsa-project.org/alsa-doc/doc-php/template.php?module=usb-audio
you can't have both the "old" usb system audio.o module and the "new" alsa snd-usb-audio.o module loaded at the same time, because audio.o preempts use of the alsa driver.

However, FC2 is loading the audio.o driver during the boot process.
I could not figure out how to prevent this, but presumably someone there knows how to do this, and it should be done otherwise any usb audio device is essentially unusable in the system given that it is using alsa.

This is also a problem for kudzu, which generates the wrong entries in /etc/modprobe.conf, specifying the old audio driver instead of the snd-usb-audio driver.  Note that the above problem persists even when modprobe.conf is fixed to specify snd-usb-audio.

Version-Release number of selected component (if applicable):
hotplug-2004_04_01-1

How reproducible:
Always

Steps to Reproduce:
1. attach a usb audio device, configure it with kudzu
2. fix /etc/modprobe.conf to specify snd-usb-audio instead of audio
3. reboot
    

Actual Results:  cat /proc/asound/cards etc does not specify the device
lsmod shows that audio module is loaded.

Expected Results:  cat /proc/acound/cards should show the audio device, it should show up in the mixer, etc
