Streaming setup help

[fuzzywuzzybear8]

I would like to be able to hear xbox and pc audio whilst using the same xlr mic to interact with the stream and xbox party chat. Not sure if this is the correct place.
I currently have a scarlet interface 2i2 if that helps

If I understand you correctly, you need a setup where
- two sound devices (xbox audio, pc audio) are piped to a single headphone / speaker system;
- single microphone is split between two different inputs (xbox chat, pc stream app)

If this is correct, your Focusrite seems to solve the second part with its two outputs, so you need a simple mixer / headphones amp (two inputs, one output) for the first part.
