Hi all. I am having some problems linking my HW 450 Samsung Sound Bar up with my Panasonic Viera TV and having the set up working as it should. I have previously had this set up and working perfectly, however must have changed a setting somewhere which means it is not working as it previously did. Previously I used a HDMI cable (v1.4) to connect from the HDMI Out on the sound bar to the HDMI 2 ARC on the TV. It appeared as TV ARC on the soundbar and worked fine. The sound bar would turn on/off automatically when the TV was turned on/off and I could use the TV remote to control sound bar sound. Now, using the same set up and connections, it doesn't work as before. There is no automatic turn on/off of the sound bar with the TV, the TV remote will not control the sound bar volume and there seems no quick fire way of even getting the TV sound out of the bar. It reads D. IN on the sound bar, and after a few selections – mainly Anynet+ ‘On' and then the speaker selections ‘TV Speaker' to ‘AVR Speaker' it sometimes works – not always though?! I have read other posts regarding similar issues and have tried suggestions but to no avail. Not sure whether a setting has changed on the TV, sound bar or indeed the connection is incorrect (but has previously worked). I do imagine it is purely a setting change that is required rather than hardware issue, but after long nights of trying (what seems like) all options, I have yet to have this working as intended and as previously! Any suggestions on what to try? Thanks in advance of any responses.
