I have now got rid of the message by replacing the HDMI lead with a digital audio connection at my own expense. However now I cannot control the sound bar volume using the Virgin remote. Has anyone managed to do this using a digital audio connection? My lead goes from the TV to the sound bar.
For info it seems that TV360 cannot handle a TV and a sound bar that are different manufacturers and the sound bar manufacturer also makes TVs., it thinks there are 2 TVs and hence the message. So I have got rid of an annoying message I did not have with my V6 box and lost the ability to control the volume from the Virgin remote or to turn the sound bar off with the TV as I did with the ARC link before.
Not sure that I can call this progress.
