First use of Mini-display port to HDMI but no sound

[JesseDiaz]

I used the official mini-display port adapter to stream to my HD TV. Video works perfect.....
But no sound...only sound is coming from the SP3.
I looked under DEVICES-SOUND and only see the headphones and the SPEAKERS as an option...so Im not sure what I have to do to get the sound to the TV.

Help

BTW, it worked...I had to restart unplug and replug back in the adapter....then it recognized the TV and Im guessing installed some drivers...Now on my VOLUME bar, there is a source for my TV
