Hi Bill.

Apologies. I forgot to add the alsamixer command so as to bypass the default 
alsamixer screen when pulseaudio is installed. The command below will open 
alsamixer and show all controls available for your soundcard. Again F4 will 
show the capture controls.

alsamixer -D hw:0

Your lsmod shows a bunch of modules loaded that are specific to the TV card. 
Quite why the tuner module isn't being loaded automatically, I don't know. It 
may be worth a look at dmesg, and see what is being loaded for the TV card. 
You may see some reference to the tuner module.

If you still can't get any sounds after fiddling with alsamixer, it may be 
worth disabling pulseaudio temporarily, in case it for some reason is not 
able to deal with sound output from the TV card. The command below as root 
will disable it.

yum remove alsa-plugins-pulseaudio

If your using KDE like me, kde-settings-pulseaudio will also be removed, so to 
re-enable pulseaudio you will have install both packages.

All the best.

Nigel.
