The options for listening to other people is fine. I can adjust the settings on that no problem. The problem is when I try to adjust any of my microphone settings or even try to enable the microphone. The settings are just greyed out. I can't do anything to my microphone settings.
My headset is the HyperX Cloud. I already updated audio drivers and that didn't help. It works on Skype and Teamspeak.
Edit: I forgot to mention I can't get Ventrilo to work. When I hit the setup button in Vent it gives me the "No mixers are available" error. It does work in Skype and Teamspeak. I also did check my Steam settings and Steam can detect my mic and it works. ****I fixed the Vent issue I switched to 32bit version instead. GTA still having issues though.
I sent in a support ticket to Rockstar and they have yet to figure this issue out. Last response from them was May 18th 2015. I can see why none of you can help at all with this if they can't even figure it out.
