Restore sound playback on external monitor

OK...here's what happened...

I sometimes plug in my LCD TV via HDMI cable to my laptop. I use it as a second monitor. The sound used to go to the TV as well. However, I inadvertently deleted the sound "profile" for the external monitor and I can't get it back. (I've attached a screen shot showing where the other profiles are, but missing the external monitor one).

How do I restore it so that when I plug in the HDMI cable the sound will go to the external monitor?

Thoughts?

:eek:
