I have the Sony HDR-SR11 camcorder and it does look like it has Dolby Digital 5.1 channel recording. Any chance Photoshop wll be getting that license?

It's possible the video has Dolby Digital (AC-3) compression scheme audio. Photoshop does not have a license for that decoder.

In CS5, the Audio is muted by default. Got to the Animation panel (Window > Animation), then verify Audio Playback button is ON (the speaker icon will have 3 waves ))) coming from it when the mouse is NOT over the button).

There's a free tool out on the web that will help you determine the encoding of your audio. Free Tool: http://handbrake.fr/downloads.php
