Hope someone can help with my problem. I've just bought a LG LHB725 Home Cinema system with Blue Ray player. It supports a number of inputs, including HDMI 1 and HDMI 2 sockets, Bluetooth, Optical, and RCA. There is a sub menu that allows one to switch between these, and a dedicated button on the Remote Control. My problem is that after having using any of these other inputs (or the Blue Ray or DLNA for that matter) there seems to be no way to switch back to ARC so that it uses the TV sound. The only way I can get it to work is to switch off both the TV (Panasonic Smart TV with AnyNet) and the LG Home Cinema, wait a while and then switch on the TV again - which in turn activates Simplex and starts up the LG in ARC mode.
Surely there must be a simpler way??
Thanks for any advice ...
