Has anyone tried to use the Party chat feature on the PC app for xbox? It works great for me unless i open a steam game. I can play Gears 4 and use party, and even games in Origin, but when I open any game in steam it mutes all chat functions. Does anyone happen to know of a fix for this?

Try Sound in Windows, find your audio device in Playback, right click and go to Properties. Advanced tab, uncheck "Allow applications to take exclusive control of this device."

@mike: I already did that, didn't seem to do anything though. Thanks for the reply!
