Hello, My first post here. I need your help guys. I have an external HDD which I would like to connect to my LG 55LA660 TV. Being a smart tv, it recognises the hdd right away and I'm able to play my video content without issues. My problem is I can only get sound from my tv speakers. My Tv is connected via hdmi 1.4 with my Yamaha YHT-598 home theater system. My HTIB and TV are connected via the hdmi 1 (arc) on my tv and the hdmi out (arc) on htib. The HDD is connected by USB to the tv. I changed the settings on my tv to get the sound via an external source but still nothing. What am I missing? Is it even possible to get the sound from my htib when playing content off the external hdd which is connected to the tv? Thanks.
