using a flash drive on 39"samsung tv which works fine until I hook up insigna sound bar ( no sound
what changes do I make besides externa speakers on my 39" samsung tv in order to get sound on my insignia sound bar. I'm using a flashdrive with a movie on it. Sounds good when I'm only using the tv but the sound shuts off when I hook up the soundbar. Using rca cable for sound.
Maybe i need to switch to digital audio cable???
