Hi guys, so i have a sony hbd - dz810 5.1 home theatre system. Before, i used to listen to audio on multi channel stereo mode (2.1 stereo but on all speakers) and my connection was through component cables. recently i bought a smart tv that has no component out ports and no 3.5mm audio jack ports so i can't connect via component anymore so i have it connected over HDMI (ARC) but now when i enable multi channel stereo mode it only plays on the front 2 speakers... (front left and front right) just like 2.1 mode. the test is fine on all speakers and pro logic etc works fine. what do i do?
