Is it possible to get Dolby Digital surround sound through the GeForce GTX 660 HDMI output while playing a game or similar. Not only with direct output from a DVD or similar.

Seams like it should be possible reading here. Anyone who has tried it and can confirm this?

EDIT1: No, it does not clearly state that it encodes to Dolby Digital, only that it can play/output it.

EDIT2: Reading further, it could only be done if the game encodes Dolby Digital or if the audio chip has the Dolby Digital Live feature.
