Behinger Xenyx 1622

Hi All,

Apologies if this has been asked before but I haven’t got time to read all the hundreds of posts!


I am running Windows 10 with Audacity 2.3.3. I have bought a Behringer Xenyx 1622 mixer with 1x dynamic mic and 1x condenser mic. Along side this I have my digital piano hooked up to the mixer.

Up until yesterday it was all working fine and I was getting ready to do some recording. However all of a sudden, Audacity is not registering a signal when I click on “Start Monitoring”. I have not changed any settings and the mics, guitar and piano were working perfectly. I have tried EVERTHING I can think of but I cannot get Audacity to recognise the signal that the mixer is putting out.

I know the USB cable and the USB sockets are working because I can capture sound from YouTube and play it back through the mixer. I’m sure it’s something quite simple like a setting or switch that needs adjusting - something obvious that I haven’t thought of!

I have tried:

  • Uninstalling and reinstalling Audacity.
  • Uninstalling and reinstalling all relevant drivers.
  • Checking the USB port (I tried the keyboard (PC not musical) in it and it works fine).
  • Checking the USB cable (I can capture sound from YouTube as mentioned above and play it back through the mixer so it works fine).
  • Checking the mixer itself (the lights move with my voice so there is a signal, plus the slider and gain are turned up)
  • Checking the mics themselves (both work fine with the mixer and I can hear myself through the headphones).
  • Checking the mics are enabled in Windows 10 under Settings>Privacy>Microphone
  • Checking the correct input is selected in Audacity (Line In is set to Behringer USB).
  • Selecting Transport>Rescan Audio Devices
  • Selecting Settings>System>Sound>Advanced Sound Options and making sure Audacity input is set to Behringer USB.
  • Everything is set to 44100Hz.

Has anyone else got any bright ideas?! The stupid thing is that it was all working fine. Something has changed but I can’t find out what.



Doesn’t matter, I’ve cracked it but thank you for looking!
