I intend to buy a new TV with dedicated wireless sound system in a few months. I would like to use the TV and its sound system just for TV while using my audio equipment (Amp, wired speakers/sub) for music. This seems intuitive but I want to confirm. Can I use a blu ray player with digital coax out to feed the amp for music (integrated with DAC) while also using HDMI from bluray directly to TV? Can I then simply turn the TV off and listen to music, or power down the amp and watch tv? Thanks.
