Kenton82 :
Ideally, could you provide the model of both the TV and the A/V system you wish to use? Are you talking about just speakers, or speakers with a 5.1 surround receiver?
My tv is samsung 50mu6172, thats samsung 6 series 4k smart tv for 2017 year. It is 6100 series for 2017 to be more precise. And my LG is DVD home cinema with model number ht306tq. So it is dvd player with surround system 5.1, actually it have 4 main speakers, subwoofer and one small speaker. Like I said before I was using aux cable to connect to my old tv on headphone jack but now I dont have that one on this tv. So I just want, when I watch movie via usb on my tv to play sound on this speakers. Thanks
