I have a win10 HTPC with all my media files on it. It's connected via HDMI to my home theatre amp which is connected to my LG tv via HDMI. If I'm watching a local stored movie or listening to my music collection on my HTPC it plays on the home theatre speakers and the TV just acts as a computer monitor. If I'm watching tv the audio is via the internal speakers or connected sound bar.
Something has happened and now whenever I try to play music the LG tv automatically overides the amp and plays the music through the tv with its media server. How do I disable this function please?? I don't really want the tv to perform any media serving functions.
