has any one connected jbl sb400 to a sony W905 tv as I am unable to select/save 'Use audio system for audio output' under bravia sync menu when selecting the hdmi the virgin box is connected to. i have jbl sb400 sound bar connected to hdmi arc and viginmedia cable box connected to hdmi 3 on the sony tv. i have also tried the virgin box to hdmi 4 and hdmi 2/mhl. with the vigin box not connected, tried 4 different hdmi cables of different brands. when i select sync menu and select use audio system for audio output i get the message "audio system active" message on the tv then "tv speakers active due to audio communication failure" under inputs when i select inputs TV and then the bravia sync menu from the remote control and then choose use audio system for audio output it works fine. i can then switch to the hdmi the viginbox or the sound bar is connected to and everything works as it should do and can controll volume via sony remote. but as soon as i turn the tv off and on again the tv (when watching viginmedia via hdmi) reverts back to tv speakers instead of the audio system. if i select inputs TV and then the bravia sync menu from the remote control and then choose use audio system for audio output and then turn the tv off and on again then the tv does stay to audio system and not revert back to tv speakers.
