No Sound from Pioneer Mixer 750 MK2 to OBS

[t0ny]

Hello,

I have the problem that I can't get any sound from my Pioneer DJM 750 MK2 mixer in OBS. The mixer is recognized, but no sound comes, 2 weeks ago it worked, but even then it did not work smoothly, do not know exactly what I did, was more coincidence than that I knew what I'm doing. All drivers and software are up to date. Is there a setting that I have overlooked? Is the problem known?

thanks for your help

Is it possible that it has something to do with the new OS monterey from Apple? I saw in the sound settings of the Macbook the following message "The selected device has no Input Controls". What exactly does this mean? Is it the driver from DJM for the Macbook because it is only for the OS BigSur?
