Hello all (I am getting desperate, please help!
I have a LG OLED65b7V / Anthem MRX 720-problem... Here goes...
I just bought a new LG OLED65b7V (I think the US model is the OLED65B7P) and I have trouble with the sound settings (in the built in TV apps, Netflix, YouTube etc.). My receiver is the Anthem MRX 720 and it’s connected to the TV through HDMI ARC in a 5.1 setup.
If I choose ”PCM” in the ”Digital output” setting on the TV, then there will be no sound from the center speaker, the surround back speakers etc. The display on the Anthem MRX 720 will read ”2.0 PCM” in this setting). On the Anthem I can then choose “Dolby Surround” via the “Mode” button and now sound will be produced from all the speakers. But, shouldn’t the receiver switch to the correct surround mode automatically?
Another question, as I “force” the receiver to be playing in surround mode – is it then “correct” surround sound I am hearing (or just an “imitated” one)?
If I choose ”Automatic” in the ”Digital output” setting on the TV (which I understand is bit stream sound), then there will be sound from all the speakers and the display now reads ”Dolby D+ 3/2”). But, the sound stutters/stops every 15 to 20 seconds. In this setting the display on the receiver switches between ”No signal”, ”Dolby D+ 3/2”, ”No signal” etc.
If I run Netflix from my PlayStation 4 instead then the display on the receiver will read “Multi PCM” (and not ”2.0 PCM”) and sound will be (correctly) produced from all the speakers. So, why this difference in sound between the built in WebOS 3.0 TV apps and the PlayStation 4 apps? As I see it, the PlayStation 4 apps works as intended?
What am I doing wrong here? In the TV/receiver settings I can’t see any settings which could fix the problem.
Any advice (settings on the TV and the receiver to try out etc.) are more than welcome!
