As for http://youtube.com/tv, it needs pulseaudio for some reason. Execute these commands through SSH before starting Chrome:
The first command tells the chrome script not to stop pulseaudio. The second command tells pulseaudio to automatically detect soundcards through udev.
Now http://youtube.com/tv will not freeze and should have sound. If it does not have sound you will need to learn how to use pactl to set the default sink.
