I just upgraded from fc11 to fc12. With fc12 comes PA 0.9.21. Pulseaudio fails to detect any of my audio cards, I have two cards. I'm positive the problem is with UDEV. When I boot the system, I'm getting a cryptic message from udev about some {ATTR ... uvent} file not found. I'm having trouble getting the error message to report, it flies off the screen before I can record it. I'm looking for advice on maybe how best to debug how udev deals with audio cards? Maybe someone has already seen this issue? I'm looking at the udev site too. Thanks, Jim
