Hi,
I've recently bought LG oled cx and tried to connect it to an old sony dav-dz260. I figured out I need to connect it using optical digital and I did it. When I try to play some 5.1 sound, e.g. from youtube, the dolby icon on home theater appears, but there is no sound from suround speakers. This means when i play test sound (from yt from tv) when right suround should play only right front plays quietly. Other speakers, including center and subwoofer, work fine. When i use test in sony menu everything is good. Dec. mode is set to a.f.d std.
Can anyone help?
