Problem solved. Siberia Steel Series V2 not Working on CS:GO/Steam

[Party Chocobo]

So I've had this headset for about a year or two and they are great. The sound and mic quality are top and at a good price. The one problem is that Steam isn't picking up the mic at all. I tried doing a test and got no response from it at all. It works fine when I use it in things like Teamspeak and Mumble but not in CS:GO when I try to use the in-game chat. I doubt it's a problem with the headset itself but I'm not 100% on that. Anyone else have experience with these?

Solved, unchecked "Allow applications to take exclusive control of this device" and had to reset it as the default device then it started to work.
