Hi . I am trying to install to OBS a connection from my external USB mixer a Behringer Xenyx 2222 usb. I am using a Mac Air M1 as the computer. I have set up the mixer in oBS but the problem is I am unable to get a signal onto OBS. I have found the signal under Mac preferences , sound under the default name for the mixer USB Audio Codec and everything is fine so I know the signal is coming into the computer. It just isn't getting onto OBS. I have looked in settings Audio and can find nothing wrong there either. How do I solve this? is there a driver? Thanks
