My understanding (actually my assumption) was that the “multi-channel audio” option simply allows the Soundbridge to pass the AC3 content unmodified out of the SPDIF port to any suitable external decoder – such as an AV Receiver. I am not aware of any other way to play these files without the server-side transcoding, in which case the option in the SoundBridge would be redundant.
I’ll ask one of the roku engineers if they have a codectype for raw ac3 content.
