Make sure the audio volume is up.  Use the "Advanced Volume Control" app
that's buried somewhere under the system menu.  (Fedora 11 is such a
hassle for something this basic...) 

Also could you provide the output of

$ v4l2-ctl -d /dev/video1 --log-status

when tuned to a good station.

Well, truth be told, the cx18 driver doesn't behave exactly like the
ivtv driver, so MythTV notices at times.  :)

Those messages are harmless, IIRC.  I use MythTV all the time.
