Is anyone losing audio after changing channels. It started when I was changing inputs, now it's happening every time I change channels. I have to completely reboot the unit. What source(s) are you using? I've had the audio dropout issues occasionally when using Directv and switching between channels. I don't have to reboot the unit however, most times I just have to either switch back and forth between channels or use the remote to switch between "Preset 1 and Prest 2" to get sound back. I'm on 1.9.1 firmware. |

I'm not sure about when changing inputs in general. And I don't loose the sound entirely.
It's somehow different:
I noticed, when fumbling around in the Setup EQ section (maybe other Setup sections, too), afterwards the audio sounds frequently (but not always) strange. The instruments are mainly as prominent to hear as I am used to, but the vocals are way too low in the background.
They are still there, but it sounds very, very strange.
I then have to reboot the unit and then everything sounds right again.
I experience the same problem, when I saw a movie via my second Raspbery Pi (Kodi, HDMI connected, movie usage only). When then I (next day) want to hear audio/music, I have again this very strange sound. I'm not sure yet if this is always the case, but it happens at least frequently.
So I reboot the unit and afterwards audio/music sounds right again.
An update:
The problem remains (newest firmware is still 1.9), but it is not necessary to boot anew. A simple change of audio inputs (coax 1 to coax 2 and back to coax 1) does the remedy. Plus, it did occur less frequent lastly.
Not audio related but I also experience that the unit freezes completely -- sometimes. It still plays, but does not accept any commands whatsoever. Then the power switch on the back is the only solution.

Not sure if you are following this or not, but some are claiming that having the network port plugged in is causing the slowdowns and lockups. I haven't personally tested removing my cable because I rely heavily on the network api. About every 3 days, I have to shut mine down because it is hosed. Luckily yesterday, it froze up for a bit, but stabilized after a couple mins. |

It's 2024, I took delivery of my XMC-2 a few months ago, and the muting of audio problem remains. Don't know yet what FW I'm on. When I play red book CD's on my Oppo 205 via HDMI it cuts off the first second or so of music. I do notice this with video program material too, (e.g. Apple TV) but it doesn't bother me so much. With music it's unacceptable. I immediately switched to the analog balanced in. But there's no way to decode SACD's in DSD extept via HDMI. I guess I'll go back to using my Parasound P7 with the a/v proc in theater bypass mode. I can still feed that full 7.1 analog from the Oppo, which has pretty good DACs. Haven't tried coax or optical yet but again, no DSD that way. Lots of really great things about the XMC-2 but cutting off the beginning of music is a deal breaker, as far as using the DAC for music goes. The Emotiva replaced an Outlaw 975 that died, which I used strictly for video content.

That is a dreaded issue and I’m so sorry to hear about you going through that…… XMC1 or XMC2. at this late date my first encounter with this goes all the way back to 2014 after going full HDMI. …… And the reality is to my knowledge you just can’t do it. Yours is the first I’ve heard of where it involves video also. I’ve got no answers for that but with music music if I totally wanted to get beyond that it would be a dedicated CD player employing a digital coaxial connection. What I thought about in my head versus what actually works in real world usage today are two different things entirely. |

Hello,
I have searched the lounge so far for my problem and didn't find the exact match:
I have bought a used XMC-2 over Ebay in March 2024 and it has also the dropout problem, but only when connected via Coax or Optical. Additionally there is an annoying beep from the loudspeakers while booting which only disappears when I choose an input.
I have contacted the Europe Emo support but wanted to know if anyone has a similar problem. Firmware is the latest (3.2).

Additionally there is an annoying beep from the loudspeakers while booting which only disappears when I choose an input. When you say "dropout problem", are you referring to missing audio from the first second of an audio track with a change in sample rate while streaming? If so, what device(s) is/are being used for streaming (streamer, DAC, etc) and which streaming service are you using? I've never heard of a beep emanating from speakers during bootup. When my amps are on during booting there's never been any sound coming from my speakers. So I have to ask, are the speakers are self-powered? if not, what amplifier is being used? I'm grasping at straws here trying to come up with ideas on how this can occur, but it always helps to know what system components are involved and how they are connected. Also, how much time elapses from the moment the processor is powered on and the first beep is heard? My questions up to now have been assuming you are using LPS which takes about 1-1/2 minutes from which to bootup, so I need to confirm this with you please, are you using LPS (Lowest Power Standby) or VRO (Video Remains On)? |

Which standby option are you using? I know it seems like it shouldn't make a difference, but it actually might with VRO because of how VRO leaves an open path for audio while the unit is in "standby" which might not be nullified by a cold boot. |

The dropouts occur while playing music, not at the beginning (I know the switching time the device needs), but randomly, several times in a minute. It seems there‘s a thermal problem, because the dropouts occur only after a while. I have no active speakers, just a chinese power amp and no exotic source players (Yamaha, Denon etc.). The „beep“ (I cannot describe it better) starts after clicking a relay inside the XMC-2. And it occurs always while a cold bootup, I always turn the power off after hearing. Just an addition: Before I had a Marantz AVR and a XSP-1 (1st Gen.) and no problems like these. |

Audio dropouts several times a minute is a lot. Without knowing the other components involved it's difficult to know how to proceed with problem solving. Can you share what the other components are that you have? Let me concentrate on the beep issue. So you turn on the processor with the rear power switch, correct? This would be a cold boot. Please look in the menu and find the setting for Standby, it's in the section called Advanced and has two choices, which setting is used? Menu::Setup::Advanced Setup:: Video Remains On / Lowest Power |

There are a Yamaha streamer and a Denon DVD-player which I only use to play CDs. They are connected via coaxial respectively optical cable. As I said, there was never a problem with these on my former setup (XDA-2 and XSP-1).
And I don‘t use the rear power switch, but a switched connector strip, without a problem in the former setup. Setting is: Video remains on.
I assume there‘s a problem with the DAC of the EMO, with HDMI there are no issues.

Please change the standby setting to Power Remains On. Since you aren't using VRO for what it offers, it makes sense to change this and I think it's going to solve your issue with the beeps. After changing this setting, use the front power button on the processor, or the Standby button on the remote to turn off the processor, wait about 1-2 minutes, then turn it back on. This will "set" the standby option. I would suggest that each time you want to shut down your system to first turn off the processor, then you can remove power from it safely. The next bootup should be silent. Please let us know how this turns out. |

I'm primarily VRO, this only occurs with a cold boot. I believe it started with 3.2, yes. I think your whine is similarly caused by VRO not "latching" and muting the audio circuit during the cold boot process. A simple test is to turn off the processor the usual way and let it go into VRO standby, then press and hold the front power button or the Standby button on the remote for six seconds which will force it into LPS. Then perform a cold boot. What happens next is unknown, but since the last used standby will be LPS my hope is that the processor will boot as if it was set for LPS and not VRO, even though it's still set for VRO internally. This is just a test. I haven't used VRO for the last couple years except just to try out some things here and there. But when I used VRO my method for cold booting is as I described above. First go into VRO, press the standby button for six seconds, wait a couple minutes, turn back on. |

There‘s still the dropout problem … Edit: The beep is there again  |

There‘s still the dropout problem … Edit: The beep is there again >:( Aaargh! I could understand getting a sound from the processor if VRO was set and something was allowing an audio path to get through after a cold boot, but I really don't understand when it's not supposed to have an open path when using LPS. too bad. I think there's a reflash needed for one of the chips in your processor. One more question about when this beep happens. Which source is active while booting up the processor when the beep happens? The audio dropout issue you are having might be related to the beeps. I say this because the dropouts happen so often for you. My XMC-2 has been on for hours and when I use Coax or Optical Inputs there are no audio dropouts when playing a music CD. If you can, please try this. Disconnect all the cables from the processor related to sources and displays, HDMI and optical and coax. Then reboot a bunch of times like you normally would and see if any beeps still happen. If so, then I think it's going to need repair. |

I have an audio dropout problem that I assumed was due to the Disney+ app on the TV (Sony). Actually I still assume that but since folks are having dropouts on the XMC2 I thought I'd mention it. We'd be watching a show and every now and then the audio drops out for a few seconds. If we "rewind", the audio is there. I had been assuming this was some kind of buffering problem on Disney+ as we don't get this on any other source that I can remember.
