I know that if the movie I watch already has the the surround signal I can just bypass using the motherboard hdmi audio out and bitstream the uncompressed sound to my receiver.
Will my receiver automatically switch from DTS to PCM (or whatever format it needs) when I'm not playing a movie, and watching a Youtube/ Playing music? In addition, is that the best way to get the best quality sound without spending a fortune? I think that's how it works, please correct me if I'm mistaken.
