You should install PulseAudio Manager (paman), PulseAudio volume control (pavucontrol) and PulseAudio device chooser (padevchooser) if you don't have them already installed. I've found that if I connect my laptop to the TV using the HDMI cable I have to make some adjustments. It may be the default setting isn't correct for your computer.

Or you could just try disabling that crappy thing called pulseaudio...
