Hi,
I'm not sure what happened, but just this afternoon, perhaps after the most recent set of FC13 updates, I have no audio and video plays at least at 8x normal speed. This includes videos from mplayer, audio from Pandora (the Adobe Air application) plays at more than double speed (by time, not by sound, as it's completely silent). It seems that VLC plays the video at normal speed, but there is no audio.
There are a couple of entries in messages that may be related:

I've tried killing pulseaudio, which results in a brief noise, then it is automatically restarted.
I have the following updates in the last week:

Is there any further information I can provide to help troubleshoot this?

I see nothing in your information that implies there should be any change in sound or video handling. There were no library changes, perhaps earlier than these?
Can you play pure audio through, say, audacious or xmms?

Is it possible that your sound device has gone bad? Did you notice any power spikes recently?
Do you have a spare sound device you can test with?
If you install pavucontrol, what does it show for devices available to pulseaudio?
Is there any chance of overheating of your system? If you turn it off and let it sit for a while (to cool), and then restart it, do you have sound and video?
It sounds to me like a hardware error, rather than software or configuration.

Turns out somehow the configuration for the audio output changed from my internal on-board sound card to the HDMI digital output on my video card. Fixed now.

Great! The devices are assigned in random order at boot unless you explicitly tell alsa to order them a certain way in a file in /etc/modprobe.d. A search on modprobe.conf (the old way) or modprobe.d and alsa will turn up ways to do this. It's been posted on this list a few times too. However, I think if you configure pulseaudio inputs and outputs using pavucontrol, it does this automagically at start up.

When I try and run pavucontrol, it just reports "Connection Failed: Connection refused". I had to install this program through yum; it wasn't installed by default in FC13. What is the default program for this? I believe it's gnome-volume-control? Does this provide the same functionality?

Yeah, I don't think pavucontrol is part of the default install. I would want it but perhaps there are too many other things in front of it.

Yes, I think it is gnome-volume-control. It is my understanding that it provides nearly the same functionality, but not completely the same functionality (I haven't used it, just seen discussions about it).
I think that pavucontrol must be trying to access your HDMI device from your video card, and this is not working. I have no trouble at all accessing sound devices as a normal user with either F12 or F14. I've never seen that message.
