ARC Dolby Digital Plus failure with Yamaha RX-V375

stu-e2 — Tue, 18 Jan 2022 19:18:04 GMT

I'm a proud owner of a new 65x95j. I am having a problem with Dolby Digital Plus (DD+) selected for the ARC connection to my trusty Yamaha RX-V375 AV receiver. If I select Dolby Digital (DD) it works. If I select DD+ the Yamaha goes silent and the display says "Decoder off" Which means it is not receiving any signal. If I then manually change the input on the Yamaha and then back again to the ARC input, it works. However I have to do this every time the TV is turned off and on again or when the audio changes to a different format.

I've tried different high speed HDMI cables including a HDMI Ultra Certified Cable.

I can also confirm DTS works ok via ARC.

The Yamaha has been working with a Fire TV stick with DD+ so this format is supported at least on a regular HDMI input.

Same with KD-55XE8505 and Yamaha HTR-4065

My TV is KD-55XE8505 but I have same kind of problem. It could be Sony's fault? If I connect Chromecast Ultra straight to Yamaha, it can decode Dolby Digital + without problems.

I have this with Yamaha HTR-4065. Using Disney+ app and Dolby Digital +, no audio. Have to do same input changing: AV4(ARC) -> some other -> AV4(ARC) then it starts decoding audio, BUT if I pause video I have to do same thing again! When audio is working, Yamaha shows bitrate as "---", so is the problem with Sony? Sending some weird signal? Do I have to contact Sony straight?

Here's a video of it. It bugs out if I connect Chromecast to TV.. Tried other cable and no change of behavior. Made fast video of it: https://www.youtube.com/watch?v=moGZLNGGMdM

Hey guys, the only common factor between you two is the YAMAHA sound system. I doubt it's a Sony issue.

Anyway, try unplugging all external devices and the TV from the mains for two minutes then try again.

This is kinda "funny". Chromecast connected straight to Yamaha's HDMI input, sound (DD+) works great. Also other codec works with ARC -> Sony & Yamaha (PCM, Dolby Digital), but not "+". Yeah It's probably some handshake(?), problem as it works after fiddling with inputs. Also CI+ CAM-module doesn't work in new television, but works in old Panasonic, fix is to buy new one.

Got to love "upgrading" to new tech, LoL. Happy weekend everyone 🤣

It is not strange that straight to an HDMI input the chromecast is working fine: HDMI input were designed for that scope since verso 1.0. ARC was introduced later (1.4 if i remember correctly) as an audio return channel on an HDMI output socket, and eARC far later within the 2.1 specification (even if it works also on 2.0). So there could be incompatibilities between hardware of different age. It is not good, but it is the way it is unfortunately

Hello! I have a Sony 55XH9096 tv and the ARC doesn't work properly for me either. 
I have to unplug the TV and amplifier, unplug HDMI cables and it works for 1 day or more but once the ARC doesn't work! 
I think the latest update is mixed in but very much into the software.

Which was missed
My amplifier is a Denon X550Bt

Hey Csabi1984, what's the current software version on your TV?

Re: ARC Dolby Digital Plus failure with Yamaha RX-V375

Csabi1984 — Thu, 10 Feb 2022 16:16:54 GMT

The software on the TV is 6.1554
The problem is not with the dolby digital but with the ARC audio "connection" between the amplifier and the TV itself. 
The usual solution is to unplug the devices for 5-10 minutes, so I think it could be a software anomaly. Of course, there was also a factory reset.

I would add that other users have experienced similar with other amplifiers.

Hey Csabi1984, does the factory reset work? @ Csabi1984 happy for you mate.

Hello! Yes, there has been a factory reset. 
I tried to unplug all the HDMI from the TV and the next time I turned it on, it turned on the amplifier (but it might just be a coincidence, 
I'm testing this now, it's good for 1 day so far). Sony HT FS-150 soundbarral. 
There was an indoor unit connected to the TV and the ARC didn't want to work with it either. I told him to just leave this and it worked out of bite.

@ Csabi1984, what do you mean by the indoor unit?

Re: ARC Dolby Digital Plus failure with Yamaha RX-V375

Indoor unit = set top box.

Hey Csabi1984, the ARC isn't used with the STB, what exactly happens with the amp?
