2 PCs 1 Mixer

[dfunk2]

So I have a unique issue.
I have this mixer:

My buddy comes to my house and brings his PC to play games together. So we have our xlr mics going to the mixer between us. And the mixer goes out to headphone amplifier:

So going to each of our headphones is a split connection one from our own PC and one from the headphone amplifier so we can hear each other. The problem is obviously the split connection makes bad static sounds and we lose stereo sound. Stereo sound is pretty critical when you're being shot at and can't tell which direction it came from. Is there a better way to make our connections so we can have stereo sound while we play?

If you connect the audio out of both PCs to stereo inputs 5/6 and 7/8 that gets audio from both PCs to the mixer. Both mics are already connected to the mixer. The output of the mixer goes to the headphone amp.
You can now mix the both mics and both PCs any way you want.

If it's done that way, it's possible to have my PC audio go to only my headphones and his PC audio go to his?
