I just bought a htl5120 bar and hooked it up with an optical cable to an apple tv 2 device. Sound comes only through the right hand side. Changing to hdmi does not change the issue. Sending music via bluetooth works and gives stereo. The point of this soundbar for me is as a soundevice with movies streamed through apple tv or music via stream. Has anyone experienced the same issue? If so, what needs to be done to correct this?
