Plase provide a longer output. Are you sure this is related ot PA?
file not found. I'm having trouble getting the error message to
report, it flies off the screen before I can record it.
C-s/C-q is your friend.
I'm looking for advice on may be how best to debug how udev deals
with audio cards? Maybe someone has already seen this issue?
we just enumerate them via udev. The output of pulseaudio -v
should tell you everything.

Both kernels are of the 2.6.32 (one is .11 the other .13) All of the sysfs stuff for both kernels are the same. So the problem is that the kernel you build doesn't work correctly with your userspace. That sounds more like a kernel build/configuration problem. /Mads ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss

Please also check: /lib/udev/rules.d/78-sound-card.rules (that file may be in /etc rather than /lib, but not sure about Fedora pkging) Also as this is an upgrade, I'd recommend checking that you don't have any orphaned files still installed that were not automatically removed. You can use a yum utility to find orphaned packages but I forget the syntax off-hand. I'm sure a quick search will find the necessary info. Then you could veryify each rule in /etc/udev/rules.d and /lib/udev/rules.d via rpm -qf and rpm -V commands. That way you can likely nail down where the problem lies with the udev config. That may or may not actually help in the case of the PA stuff. It could still be the kernel that is causing you problems.

Looks like a syntax error in one of the udev rules.
Perhaps you can see if the message shows up in /var/log/syslog and then
grep for that string in the udev rules directory?
