My inputs soundcard record the main output Cubase 12 Mackie Pro fx16

Hello,I don’t know how to fix this, but for the past few days my sound card (Mackie Profx 16) and Cubase have been malfunctioning. I can’t use the audio inputs because they’re picking up the output signal and looping. I’m so frustrated! If anyone has a solution, thank you.

Hi,

This usually happens, if there is any kind of Loopback enabled. Most often, you can enable/disable this on the Control Panel of the Audio Device.
