Overdubbing problem with Behringer UCG102 interface

Hi there,

I’m using Audacity 2.4.2 with Windows 10, and keep running into the following problem:

I recently bought a Behringer UC1602 to do some recording with my bass. Simply recording bass parts has been no problem, and Audacity seems to recognise the interface without any issue. But I also want to record bass tracks over drum parts that a bandmate sends me. I import the drum track as an mp3 ready to record a new track over, but as soon as I’ve done this I start getting the classic “Error opening recording device, -9997 invalid sample rate” message as soon a I hit the record button.

If I delete the imported mp3 track the bass starts recording normally again!

Any advice? I’ve tried tinkering about with the sample rates but that hasn’t done any good. I also thought about downloading a driver but the Behringer website just seems to list ASIOs, which I understand are not compatible with Audacity.

Any help would be hugely appreciated!


Overdubbing is the magic time when Audacity has to mange both Record and Play at the same time and both have to be perfect. 44100, 16-bit, Stereo is a good generic setting for a start, and both directions should match.

To get down to “push this button, push that button,” we have to meet the device…and I couldn’t do it.

There is no UC6102 or UC1602.


Quite right - it’s UCG102. I mistook the G for a 6!

I’ve changing to 16-bit, too. Still doesn’t make a difference, unfortunately.

I’m pulling down the instruction book (it’s reluctant), but from what I can see, you may need the ASIO drivers to do perfect overdubbing. You are right, Audacity doesn’t get along with ASIO software.

Perfect Overdubbing is when you listen to the backing or rhythm track mixed with your live performance. The Behringer UCA-202 has a switch on the side called Monitor. That switch lets you hear your outgoing (live) instrument during the performance. Your 102 doesn’t have that.

You can’t listen to Audacity “folding back” your live performance to you because that will be late or have an echo in your headphones. That’s one of the things ASIO tries to solve.

So even if we get everything working totally perfectly, it’s never going to be, well, perfect. You will always listen to the backing track and play into silence (other than the sound the actual bass in your hands is making). It’s recording the live track, you just can’t hear it live.

Close Audacity. Unplug the 102. Wait a bit and plug it back in. Let Windows get used to it and only then Start Audacity.

Look at the Microphone drop-down on the Audacity Front. You should see a device something like USB Audio CODEC.

That’s (probably) your 102. Now try to find the same thing under the Speaker drop-down.

OK, so far?


Yep, done that. Can’t give it another go just now but will try again ASAP.

I really appreciate your help. Sounds like this interface simply might not be the one I need. Will try again after letting Windows get use to the USB connection though.
