What audio files are you using? If it's streaming, to me that suggests that the files are compatible.

If you are hooked up to a receiver, and you have disabled your television speakers (in lieu of the receiver), you might try to enable your TV speakers to hear the audio.

If you want that audio to come out of the receiver, I would recommend using a digital audio cable from the television to the receiver so that your audio will be ported to the receiver.

Hope that helps, and keep me posted.
