I have been dealing with this annoying (and stealthy) issue with the UMC-200 for quite some time and wonder if anyone here could help or have any suggestion. *Help would be appreciated in reproducing the steps below to see if it is just my faulty unit or some sort of a bug.* Issue description: Whenever the music stops a low volume and low-frequency thumping heartbeat-like sound is constantly emitted from the subwoofer connected to the UMC-200. (yeah I know there are tons of possible causes and ground issues that pops to mind but bear with me, I am pretty sure I've ruled them all out) System details: - Windows 10 PC with Intel(R) HD Graphics 4600 (HDMI)
- UMC-200 connected to the Intel HDMI and presented as UMC-200 (Intel(R) Display Audio) in devices
- UMC-200 Firmware:
V1.52.02.39 - Subwoofer connected to RCA LFE out on the UMC-200
- JRiver in exclusive mode (happens with other software as well)
Steps to reproduce: 1. Connect UMC-200 to PC HDMI 2. Configure JRiver in Exclusive mode:  3. Play audio content 4. Press stop Thumping heartbeat now heard constantly from subwoofer, until next play. Verified checks and facts: - This does not happen in "Shared mode" where the OS is maintaining the connection to the UMC-200 audio device (ruling out any cable and grounding issues...)
- The heartbeat sound is not affected by UMC-200 volume (until mute)
- PC Mute does not affect the heartbeat sound
- Muting the UMC-200 stops the heartbeat sound until unmuting
- Cycling between HDMI inputs stops the heartbeat until repeating the above reproduction steps
- This happens only when the player app is operating in Exclusive Mode with the UMC-200 audio device
- This happens with Dirac as well (ruling out a JRiver issue)
- The subwoofer volume affects the heartbeat sound
- Replaced all cables and ports just in case with no change
Any ideas? Suggestions? Anyone with a UMC-200 in a similar setup kind enough to try to check the simple reproduction steps and report? |

Common issue that has to do with timing issues - what Emotiva told me when I had it happening to my Fusion.
There's a program out there that will help you, but I forgot what it is, since I don't use them anymore. Sound Stream, Quiet Stream or something like that. Basically you need a program that actually forces your computer to mute in between tracks. I might still have it on one of my laptops, I'll check if I get to them this weekend.

Thanks @thk! A program might be useful. Although probably not muting the PC (as doing it manually does not affect the issue) but more like "engaging" with silent whenever no other app is engaged in Exclusive Mode. Comes to think about it, perhaps just playing silence in a shared mode player in loop in the background would help!  (Exclusive Mode apps will take control when they are playing and the silent shared mode player will jump in between plays to subdue the notorious heartbeat phenomena) Bottom line - it seems more and more like something that is missing from the UMC-200 software flow. A bug. Probably not many ppl use it with a subwoofer, HDMI and exclusive mode? Or it could be just my faulty unit. It is just that the nature of the fault doesn't seem to be hardware related (or it would always be present, regardless of software mode). |

No, it's not a "faulty" unit. That's present in most all of them, and the Fusions. I forget the thread I read, and I can't find it on the Emo Lounge, so it might have been elsewhere, but it has to do with the processor not muting the timing sequence being passed through HDMI. So you need something to quiet the stream when there's no actual audio present.
There's a specific program that'll do it, I just need to recall which program that is.

I have had a UMC-200 since they were released, I have also installed 2 more UMC-200's for friends and family. Despite being connected to all sorts of sources, ver many years, in every possible combination and using every available interconnect style none of them, not a single one, has had the issue that you are describing.
To put it bluntly I firmly believe that your problem is with the source and I respectfully suggest that you move over to searching for solutions in that direction. The fact that is connected to a UMC-200 is almost certainly irrelevant.
Cheers
Gary

^ I can absolutely attest that the OPs issue IS the source, but it's only going to be present because of how the UMC is handling the signal it is receiving.
My MC-700 does not have this issue on any of my computers, new or old. Both my Fusion 8100's had this issues on all of the aforementioned computers. None of my Integra AVR's have this issue on those computers. I'm trying to track down the program that smart-mutes the stream that is passed via HDMI, that fixed all of the issues for me.

I also had quite some issues with my UMC-200 and various HTPCs back then. This was always solved / had to be solved on the PC side of things.

Cool Kid! Thanks!
It sounds right, I'll check that as soon as I'm back home (if I could find an active source/mirror to download from).
Did Emotiva ever mention a Firmware update to fix that on their end?
Is it expected to affect only the UMC's subwoofer output?
Is it expected to not be affected by the UMC's hardware volume?

Changing the type of dithering in jriver settled the clicks and pops between tracks on my xmc, might be worth a shot if possible |

It is not the usual clicks and pops class of issues (for one part clicks and pops coming from jriver are affected by the UMC-200's hardware volume and are not specific to the subwoofer output, unlike this pulses issue) |

That may trigger other ideas - but so far - I still don't think it originates in the UMC-200. Thx, Mark |

It is not the usual clicks and pops class of issues (for one part clicks and pops coming from jriver are affected by the UMC-200's hardware volume and are not specific to the subwoofer output, unlike this pulses issue) It will vary sometimes on which programs are open, and if the program is emitting a standby stream. Sometimes shutting programs down ended the problem for me. They mention a few potential programs to use to help in a google/bing search. I just want to throw out there - since my current setup doesn't do it without anything extra - is Windows up to date? This is a Windows problem, so check and see if Windows is up to date. |

Gosh, that fixed it! Guys - I've been mentioning this with the support of several vendors and none even recognized the issue, let alone refer to a workaround solution which practically solves this. Thanks! Very much appreciated!  |
