Am playing with my girlfriend who is currently overseas over discord, and it works fine until we're both in the game. It keeps glitching out or not sending any audio at all.
It used to work perfectly but it is now broken.
If she alt-tabs from the game, the audio works fine. Same if I alt-tab from the game. When game is on full it glitches.
Any other info I can provide, please ask me.

Appreciate the time.
