Behringer UMC22 2nd Channel audio output doesn't work.

I’m trying to setup my Behringer U-PHORIA UMC22. I plug into channel 1 and get the audio output just fine, but when I go to the second channel there no audio output whatsoever. I’m not sure if I’m missing something or what. I’ve also tried it on the Microsoft version of Adacity. It shows no audio from the second channel.

My second question is once I get audio to work out of the second channel how would I record both channel 1 and channel 2 on separate tracks at the same time? Is it something I select when I create a new audio track?

Thank you in advance for any and all help that you can provide me with.

how would I record both channel 1 and channel 2 on separate tracks at the same time?

That one is pretty simple. If you can convince it to record in Stereo, it will produce two independent tracks married in stereo. Use Audacity Split Stereo To Mono from the menus on the left.

I bet you’re going to ask how to do that in one pass. I don’t think you do. Audacity will only record from one device or thing. Two mono tracks come from two things.

There’s a way to sorta fudge that. Audacity will record from multi-track devices (over two) and last I looked, it would do one stereo and a bunch of monos at the same time. So technically, tracks 3 and 4 would be two mono tracks at the same time. Throw everything else away. But the Behringer UMC22 won’t do that.

In no condition can you record two tracks with different technical standards, 44100 and 48000 sampling rates for example. Pick one.

As we go.

but when I go to the second channel

What does that mean in detail? Are you plugging a guitar into the second channel?

The UMC22 is natively a mono (one microphone) device. It’s a sister to the UM2 that I have. If you just plug it up and don’t do anything else, you’re likely to get a mono track. That “two track” business is from Marketing and Publicity, not Engineering.

These two are the solutions to the problems people run into when their goal is to record their microphone on one channel (voice-overs or audiobooks) and they buy a Scarlett 2i2 by accident. The 2i2 is a native stereo device. Forcing a 2i2 to record mono can lead to serious overload and clipping problems.

To force both channels on your UMC22 to work (I’ve never done this), you have to tell the system to recognize it as a stereo device and I think you have to do that all the way back in Windows Audio Control Panels. I’m not a Windows elf, so you’re on your own there. Audacity gets its sound from Windows, not the device.

Oh, and you shouldn’t use Skype, Zoom, Meetings, or other chat program while you’re messing with the UMC22. Zoom takes over your Windows sound services. It doesn’t ask and you can’t stop it.


Voice-Overs. I guess it’s Voices-Over, isn’t it? “Over” is a prepositional modifier.

In Audacity, you need to set “Recording Channels” to Stereo in the Device Toolbar

In the Windows search bar, type “mmsys.cpl”, then select the Recording tab. Select your device (UMC222), then Properties. On the next windows, In the Advanced tab, under Default format, set 2 channels.

In the Windows search bar, type “mmsys.cpl”

Is that the only way—or the best way—to get to the Windows Control Panels? Suppose you have to access the panels more than once, say in a month or two?

Are you plugging a guitar into the second channel?

The reason I ask that is the second input of the UMC22 doesn’t supply 5 volt computer microphone phantom power, 48 volt XLR microphone phantom power, or volume boost for a microphone. So if you do plug a plain microphone into the socket, it will either arrive a thousand times quieter than you’re expecting, or not work at all.

It’s perfect for a guitar pickup.

I’m using a mic for channel 1 and a guitar for channel 2. Channel 1 is great, but still nothing on the second channel with the guitar. The volume on both the record and guitar are up, but nothing showing on the monitor.

I go into mmsys.cpi and it doesn’t show the UMC22 in the recording tab.

I’ve never met Cortana but the Top-Password reference list seems to like it.

I wonder what’s wrong with it.

Here’s a picture of what I’m running on the desktop and the UMC22 setup.

nothing showing on the monitor.

Missed one step. Press Direct Monitor and plug your headphones into the UMC22. Turn up OUTPUT. Can you hear both?

I go into mmsys.cpi and it doesn’t show the UMC22 in the recording tab.

It won’t say UMC22. It will say its USB name. Mine says USB Audio CODEC.

Some Windows panels have sound meters. Does yours and does it bounce for both microphone and guitar?

Another caution. Plug everything in and make sure everything it OK and then start Audacity. Audacity naturally checks for new connections when it starts. You can force it to check later with Transport > Rescan.

So, USB Audio CODEC, it is, then. You should notice the entry disappears as you unplug the unit. (Don’t do this with Audacity, otherwise you will have to do Transport > Rescan Audio Devices.

Good question. Microsoft keeps changing things around, even within Windows 10, so the above affords consistency throughout most versions of the OS.

On my machine, I can right-click on my speaker icon, then select “Sounds”, but the option immediately above says, “Open Sound Settings” which is not only confusing, but takes you to the wrong place, so it is easier in the long run to just try to remember mmsys.cpl, and to look it up when you forget it. BTW, the Windows Search bar is located on the task bar right next to the magnifying glass.

Or just:

Figured it out. Well, from here and YouTube. I had to go into the sound manager of Windows select the recording tab and select the USB mic and then to properties and advanced tab selected 2 channel on the drop down menu and unchecked the boxes. Hit apply and it was ready to go. Thank you all for all your help. I’ll post the link to the video that also helped me.

The bottom device is correct. You should be able to either speak or strum and the light green sound meter should bounce darker green.

The guitar is going to be quieter than your voice, but it shouldn’t be dead quiet.

If you only get your voice in this test, then you get to plug your headphones into the UMC22. If you still only get your voice, then there’s something wrong between the UMC22 and the guitar.

Next pass is pull the sound cable out of the guitar and put it back in firmly. Then pull the other end out of the UMC22 and put it back in firmly. I have a device that seems OK when I plug something in, but in fact it’s a small fraction of an inch off and wants to go in even further yet. It won’t work until I push it in that last little bit.

Is it the right cable? A guitar cable is Tip/Sleeve.

One black band.

A stereo headphone cable is Tip/Ring/Sleeve and has two black bands.

If you use a headphone cable on a guitar, you have about a 25% chance that it will work.

We had it that far.

I remember vividly vising someone’s house and they were using a Windows laptop to control their sewing machine. I’ve had PCs since DOS (still in use), but I could not follow what they were doing. My eyes started to water. “But…?” “How…?”

Those Macs are looking better and better.
