hello, so I'll try to explain it in more detail.
I can only explain it with the use of DSU.
at the moment i only use the phantom center. therefore i can not find any problem here. I can only find problems with the surrounds.
how does the problem arise.
I turn on the Sony TV KD-75XG9505.
Then the rmc with rear cold switch.
Detection with DD on DSU
I start the Delux music channel on the TV.
Now it happens that the surrounds are different in volume and are also quieter than previously set via the dsp.
At first I thought I was making a mistake in saving the dsp setting. but by testing with the surround mode. I had to find out that it always worked with all stereo and no problems in the surrounds with the level.
different signal processing or no correct detection?
Even repeated cold starts did not bring any improvement. so i didn't suspect the problem with the rmc (don't blame all problems on emotiva, i think it's unfair). I suspect many problems come from the other manufacturers, which are also reflected in different problem cases.
Now I had to get rid of it, you can tell I'm an emotiva fan😬.
so i started the software of the sony tv. and then the rmc with cold start. great everything is as it should be 💪. this is my daily ritual. I will try to solve this automatically with a cold start of both devices. So that the hand shake works. If the rmc receives or rather recognizes the correct signal, it also works.
But all problems are not solved by it and I am powerless with some things.
what problems are there.
when I listen to music via delux music or amazon, short tones come off that sound like a cell phone disturbs the radio station. there are different tones and brief dropouts as when a film is being played.
here it is the well-known short zips and failures. my guess is the communication between tv and rmc.
another error that does not occur with movies and music on cable TV. when the music app is changed or not correctly terminated, it is in tv mode and that goes back to the music app. Suddenly there is no more sound from the rmc. here I have to restart the software on the tv and also the rmc. and everything works as it should again.
I hope the translation was understandable.

annotation.
there are also short zips when changing titles. so it is always a transmission from tv to rmc. I also had this problem when I used spidf. I only had this problem with the new sony tv with the umc 1 or rmc. with the old sony tv i had no problems changing programs.
note 2
I now use wifi.
I have to try out whether this also occur with direct LAN. in order to be able to narrow down everything better

If this has only happened on a rare occasion, it sounds to me like the “DSU bug” that Dolby has acknowledged and is currently working to fix. It affects every platform that uses the newer DSU and isn’t specific to your XMC-2. Dolby hasn’t given a specific date for an expected patch, but I’ve been following the “Marantz AV8805 Users Thread” over on the AVS Forum for any updates. Since D&M was the first to confront Dolby on this matter, they will likely be among the first to release the fix. My TiVo also outputs DD 5.1 and I can definitely switch between channels and find some where the voices of the commentators are clearly “centered” and other stations where they’re clearly “spread” into the L/R, but I believe that’s how the content is coming in. However, I’ve never had an instance where they’re starting centered and then suddenly shifting outward. If the latter is exactly what you’re experiencing, that’s definitely the DSU bug. Since DSU is the default when your XMC-2 is in the “Auto” mode, and since there’s no other upmix option for DD until Emotiva unlocks it (since Dolby lifted their restrictions), there’s nothing you can do. However, for PCM based content, you can try using DTS:NeuralX as an upmixer and compare the results. I think you are referring to the Dolby Bleed Through issue. Sounds similar to it, but I thought that issue is for bleed through to the surrounds, not mains. My problem sounds more like Center Spread being applied to non-music content. It definitely wasn't a source issue because I was able to correct it by re-selecting surround mode (no change to TV channel).
I caught the other bug again this morning. Stereo music in surround mode being played back to the mains only. I confirmed nothing was being sent to the center this time. Maybe auto mode picked stereo instead of surround and it is just a display bug? I'm going to change from auto to Dolby Surround and see if that helps. Probably try out DTS:NeuralX, too. Was hoping to get to a set it and forget it state with the XMC-2. Never happened with the XMC-1 as I was always fighting music/movie mode selection.

I must be getting senile. Had an XMC-1 for years, and a few months ago I got an RMC-1L which has has been great.
One thing I used to do when playing 5.1 SACDs was getting my back channels to upmix so all my speakers were engaged. I have a 7.1 system. I’m trying to get the same thing to work with the RMC-1L. But the rear channels are silent. I expect i’s a mode setting, but I can’t seem to figure it out.
There should be a way to put those back channels to work. anyone know the magic formula?
Thanks
Mel

Thanks Mel Did you try Dolby Surround or DTS Neural:X upmixing modes? _ Those won't work on DSD, only if he chooses PCM. The XMC-1 has the DSD "+ Backs" mode he's talking about. The G3P processors do not. |

Thanks. Tried several modes. Regular CDs upmix. My Roon setup upmixes. 5.1 SACDs don’t.
Curious.

It was set to PCM (Oppo) but no back channel output.

Please note that since there is no tone in written words, My next question is coming from a place of curiosity and not frustration. Middle of next week ends my 30 day trial with my XMC-2. Thus far the over under for me is that I really love it, however I do have a quick question for those that also own this device. I make sure to use this device multiple times a day and in doing so the only thing that has happened more than once is some odd sound issues. Sometimes I will turn it on and the speakers will pop and then I have to do a hard reboot to get the sound back. I have also had it where the sound would be muffled and super distorted, coming out of the left and center channel. Again after a hard reboot these things disappear and correct themselves. In the 2 plus weeks I have owned it I have only had to hard reboot it 3 times, and each was around loosing sound or locking up. Again it has not been happening with frequency(which is why I had not felt the need to call support), and I expect this now and again as had happened with my Pioneer and Marantz at one time. I am 98% sure at this point I am going to keep this bad boy, however I wanted to make sure these challenges are not a sign of things to come;) The only other reason I would consider returning it would be to put the extra $$'s in for the RMC-1L or RMC-1!!

I have not had these issues and have owned my XMC-2 since they first came out after trading in my XMC-1. A few firmwares back I had the "loss of audio" issue solved mostly by switching inputs, but that has ben fixed via firmware update. I'm on the latest firmware. Occasionally I will get a small "tick" souund when using the Apple TV4K, but not always. No big deal. Mine is used daily, on and off several times a day, in both Video Remains On (VRO) mode as well as full power mode using the XPA-5 Gen 3. My system has been very stable since firmware v2.2. If it were me I would give Support a call and go over the issues with them. They may be able to solve the issue over the phone. At the very least they will have a support record. |

I would at the minimum exchange the unit for another one. These issues that you are experiencing are not normal and should not be accepted as such. I don’t have any of those issues and I bought my XMC2 on Day1. I would call them, describe your issues and get it sorted. That’s the best advice I can give you - don’t accept a defective product. |

Oppo set to PCM Its not unprecedented with new AKM dacs compared to the XMC1'S that processing may be different [may even have to do with dsp horsepower or particular upsampling rate of the audio ?] . Found this drawback for a theta casablanca 3hd which may have trouble with an oppos preferred decoded lpcm 88.2 sampling rate for sacd dsd  ; |

Seems like nobody acknowledge ARC-CEC malfunction when VRO is off at RMC-1 since I raise the issue here.
When ARC Power On is disabled and VRO is On, HDMI connected device power on and off is not affected to RMC.
But when VRO is off, RMC follows connected device power on and off no matter ARC Power On is enabled or disabled.
Or Emotiva does not have any interest of ARC function. Like, this forum's major followers said that ARC is not reliable.
I agree that ARC is unreliable but this kind of error I never experienced before with other brand.
