Bought this from Reliant Direct a week ago and I'm getting a lot of grief with HDMI/ARC and CEC.
It's connected up as following:-
Soundbar HDMI Port 1 (ARC) <-> LG C7V HDMI Port 2 (ARC)
Soundbar HDMI Port 2 <-> Panasonic Blu-Ray DP-UB820
Soundbar HDMI Port 3 <-> NVIDIA SHIELD
LG C7V HDMI Port 1 <-> BT Set Top Box
At first, I had some grief getting audio from the TV to the soundbar, then it settled down for a while. Few nights ago, I noticed the audio from the BT Set Top Box and/or Live TV was crackly - I powered everything off and back on, seemed to fix it.
Two nights ago, the crackly audio returned and got worse. Power cycle didn't fix and then eventually it decided there was going to be no audio at all.
I swapped cables, plugged and unplugged things, turned Simplilink (LG's implementation of CEC) off and on, switched to PCM with no avail. I left it until yesterday morning, went back to it and then went into LG sources menu and removed the soundbar, plugged in and out and eventually the CEC Gods decided there should be audio and it came back.
Jump forward to last night and similar thing happened but without the crackly audio build up and it just dropped the audio from the STB/Live TV again. I couldn't be bothered to faff on last night and left it until this morning again. This morning, after 30 minutes of faff in LG's sources menu and adding and removing things, the audio is back again.
I've come from a separates set up with a Denon X4200W where everything just worked fine for the last three years to this waking hell of being unable to just sit down and listen the TV on a night. Needless to say I'm a bit fed up with it. The Denon was connected to the TV on ARC and it just worked without issues.
Has anyone had similar experience with this combo of LG TV and Samsung soundbar? I don't know if the problem is the TV not liking the soundbar or the soundbar just being borked. It was bought from Reliant Direct (via Amazon) so I'm fairly confident of being able to return it without too much grief, but would really like to know the cause and if possible fix... I don't have a spare TV lying around to try things out with, though.
[EDIT] Bit of googling brought up a 22 page long moan fest about Samsung and HDMI CEC. Guess this thing is going back...
