@dheav, do you have one of the "Volume modes" enabled? You won't get any sound if you do and the video doesn't contain a stereo audio track.
Appears Roku is not playing DTS only Audio Tracks, such as this spec from MediaTab

@Rothman Roku only supports DTS audio if it's a) in the MKV container and b) you are connected to an AVR via HDMI and the AVR supports DTS. In this case it is passed through to the AVR. But if the DTS is in another container, officially DTS isn't supported, although I have had success playing it from TS/M2TS containers.
One other comment about the info you posted. That audio track is DTS Master Audio, which Roku does not support. It is lossless audio, and Roku does not support any lossless audio codecs. A Roku will pass LPCM, but it's unlikely you have any lossless audio in LPCM.
In theory, the lossy DTS core audio track should still be sent to an AVR connected via HDMI, again only from a MKV container. But that has always been hit or miss with my movies, so I instead have my DLNA server transcode the audio to Dolby Digital. But there's no way to listen to lossless audio through a Roku device.
Cool - thanks for the knowledge. I code everything in mp4 so looks like I'll recode my blu-rays into AC-3 & stop doing DTS passthru. Just CPU time 🙂
