Hello everyone,

maybe one of you can help me: I am producing tutorials with OBS.
First - i had 2 Cams (Papalook & something) an 1 Microphone. That worked well.
Then, because of better Sound (Grand Piano), i got another Microphone.
So i connected 2 Cams and 2 Mics to the PC.
-> Result was, that in OBS i lost one of my cams. I can add the cam, but only a black screen is what i get.

OK, then i bought a SoundMixer (Yamaha MG12), to have only 3 connections, not 4. (2xCamera, 1x Sound)
But this is the same result :-(

If i connect only 1 Mic, then i can use 2 Cams in OBS.

Some of you guys have an idea ? PC is an acual one with 6xUSB3-Ports, Windows Professional.
Thanks, Oliver
