First: Where are you? You are unlikely to get DVB off a cable system in
the USA. Digital cable is generally QAM256, and you will not be able to
get anything but unencrypted channels, most often just the local
off-airs and perhaps CSPAN or the like.

Second: What hardware are you using to receive digital signals, how you
do that depends a lot on your H/W.

Last: xawtv is only for analog cards, or so I thought. If you get no
sound it's probably your audio setup.
