So I tried literally of the solutions people had below, and this is the combination that worked with my Galaxy Buds: 1. Sound control panel - disable the "headset" option. Mine was "galaxy buds.....AG" 2. Turn on (or enable) Stereo Mix (not sure if that has anything to do with it, but I did it.) 3. Find App And Volume Preferences - make sure [b]D2 [edit] AND STEAM[/b] has your headphones selected 4. In the Sound menu, under Input - Select Stereo Mix (again, not sure if this means anything, but mine is working now, so.) 5. in Sound Control Panel, under Playback> right click the device> properties> advanced> uncheck "allow applications to take exclusive..." hit apply. Also, thanks to literally everyone in this post. because this is literally a conglomeration of all of your solutions. QUICK EDIT: PLEASE NOTE - Just had to redo this b/c I got new headphones... for STEP 3: Settings>System>Sound - then scroll all the way to the bottom, and its the last thing. Took me 40 minutes to re-find this... jeez.
