Sound Broken By Some Update?

[Richard Heck]

For a few days now, I'm having trouble with sound on my machine. I'm 
running a fully up to date F16, with KDE. This seems to have started on 
the 20th, and I'm seeing errors like this in the logs:

Feb 20 10:58:24 rghquad rtkit-daemon[1501]: Successfully made thread 
2834 of process 2834 (/usr/bin/pulseaudio) owned by '500' high priority 
at nice level -11.

Attempts to start pulseaudio manually cause the same errors, initially, 
but then it eventually works, giving me only this error:

/home/rgheck/ > pulseaudio
E: bluetooth-util.c: Error from ListAdapters reply: 
org.freedesktop.systemd1.LoadFailed

Nothing's changed with the soundcard, which is fairly basic:

08:01.0 Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 10)

Ideas?
