Hi, anyone can help me please? how do I set up my Yamaha MG06X sound mixer to my Q90 sound bar? I have Q55 tv and would like to have a karaoke set. I have already wireless mics,Yamaha MG06X sound mixer, Analog to optical audio converter (to sound bar), and optiocal to analog audio onverter (from TV to sound mixer). I have signal from mics to sound mixer already, but I still dont have sound on the speaker. Many thanks for your support
