I've set the mythbackend to be ALSA:pulse and the mythfrontend to be
ALSA:pulse.  I still don't get any sound from Live TV.  Can mythbackend
read from pulseaudio?

I have noticed that on bootup, the sox command doesn't output any sound
until I modify a few settings.  I've restarted mythbackend once the sox
command works and still no sound.

I normally use the OSS one since I get sound (I just don't use LiveTV). 
So, I'll try to get a backtrace.  I'm guessing that will involve
compiling mythbackend myself.
