Using 2 pcs to broadcast via OBS to FB Live

I am looking into live streaming with obs to fb live. My issue is that I do not know how, or if its possible to use sources from 2 pcs to broadcast.

I have my cameras on my desktop and my audio on a laptop (mixer to laptop with serato audio).

Anyone?

I cant say with OBS, but with Wirecast, you would just use Desktop Presenter one whichever secondary computers you need to stream to the primary from.

You can use audio from another pc on OBS studio. You just need a sound card/interface on the streaming pc. I dont know if they fixed it but OBS in the past had issues with interfaces with more than 4 inputs so I would use one with just 2 inputs.

Thanks for the info guys.
