I have just purchased this TV and also soundbar MT300. As there is no HDMI connection on the soundbar I am using the optical connection. I wish to control the soundbar audio from the TV remote by using the IR Blaster feature, however, when I follow the procedure my TV does not recognise my Sony soundbar. Please advise how this can be set up as I can't believe that a new Sony TV and soundbar are incompatible. Thank you.
