I am having issues with the spout receiver. I see my senders, but when I select them all I get is a black screen. These same senders work going into OBS, Volta and the spout test receiver.
Thanks

What are your senders? Spout test and Resolume are good here. Is spout on your path?

The senders I've tried are Volta-xr, NestDrop and the spout provided test ones. Spout isn't in my path. All of these senders work going into other programs that take spout input.

Volta is no longer available it seems, but I tried NestDrop which just worked for me. So the senders likely not the issue. There have been a couple of threads that mention this issue (in 2015 and in 2022) but there's no confirmation that the suggestions offered worked. Might give you a few more things to investigate though.
