These are analog signals.

You mentioned cable companies use QAM64 and QAM128 IRC

HVR-1800 card will automatically do the conversion for you. You don't need
to select anything.

I don't think any other choices make sense (except for OTA if you were using
an antenna).

> If you have ALSA set up correctly (which usually means not doing anything
on recent distros) you should be using ALSA:default. But first you need to
get a picture. You can worry about sound later.
