TVout is in reference to Composite, S-Video, and (I think) Component outputs.

HDMI video is fully support on nv50-era GPUs. HDMI audio may be a bit
spotty depending on which GPU you have. (lspci -nn -d 10de: should
give you the info). Pre-GT215 GPUs have to get audio input via SPDIF
from the sound card, and nouveau doesn't quite configure that properly
- it might work, it might not. For GT215+ GPUs, HDMI audio should work
fine.
