Unlike some, I haven't had any problems with audio under F8. After performing the upgrade, everything seemed to work OK.
However, a couple of times something has gone wrong; for example, just now I had to restart messagebus and haldaemon and now sound doesn't work anymore. Under F7, if memory serves correctly, # service alsasound restart
(or something like that) would reinitialize the audio subsystem, but F8 doesn't seem to have that anymore.
I've tried using the Reinitialize audio drivers
command on the System tab of system-config-sound, but it always returns an error message: "Unable to remove kernel modules"
That program says I am using ALSA; no mention of PulseAudio. At this point, I don't quite understand the relationship between the two.
The soundcard is an onboard Intel:
Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
At the moment I am running F8 with the following kernel:
$ uname -r
