Hey v12 to 12v. I had not thought about the 5.1 playback issue for a while. Now that you bring it up again, I'm wondering the same thing. I know the more active guys on this forum have been talking about supported audio formats in one of the threads, but no mention of any 5.1 audio. To be honest, I don't even know what 5.1 formats exist for storing and playback of audio on computers, let alone in the Model S. :)
