Audio track select depends on the device. Also, the file must not be transcoded. So, it the file can be played without transcoding, and your player supports it, you can choose different audio tracks. My Sony S3100 Blu-Ray players will do it. So will my Samsung BD player. The TV is hit and miss, although it shows the option there. It just doesn't actually select a different one sometimes. My Panasonic TV won't, but it's pretty old. The Roku player has the ability, but it's very picky about which type of file it will work with. it doesn't work on anything I have.
