I get no sound.

-Put "options snd-hda-intel position_fix=1 model=3stack" to "/etc/modprobe.d/alsa-base".

Later noted that I got sound if I choose AD 198x Analog as playback

Preferences -> Sound, On the Sounds tab at the bottom I put HDA NVidia as Default sound card. This made it possible to choose Autodetect under the Devices tab.

CD plays fine, but I get no sound in DVB-T in Kaffeine.

I was just missing the libxine-extracodecs

 apt-get install libxine-extracodecs
