Thanks for the tips, Colin.

So I tried running pulseaudio -vvv from the command-line to see what was
going on in the PA side. I initially started without libflashsupport.

Surfing over to a youtube page with video and audio, I saw the usual
video and couldn't hear any audio. No activity on the PA front.

I then "yum install"ed libflashsupport, which resulted in the following
output from PA:

D: module-hal-detect.c: dbus: interface=org.freedesktop.Hal.Device,
path=/org/freedesktop/Hal/devices/computer, member=PropertyModified

path=/org/freedesktop/Hal/devices/computer, member=InterfaceLockReleased

All normal, I figured. (Side question, though: how does flash-plugin
make use of libflashsupport when it's just a library that sits
in /usr/lib64/? Is there some rpm post script that somehow links the
library to flash-plugin?)

After installation, I restarted mozilla and got:

I: client.c: Created 1 "EsounD client (UNIX socket client)"

At least mozilla seems to have connected fine. Then I surf back to the
youtube page, and again no audio and no activity on the PA log side.

I don't know what flash-plugin uses for audio so I'm not sure what's
missing and why the two aren't connecting. Any more suggestions?
