Well I received my R5 Aurora 3 weeks ago and set up my Team Speak and tried to talk nothing.
The mic keeps going to mute even when I unmute it on the Audio Realtek Audio.
I don't have a sound card and I'm using the motherboard sound system.
My Head phones are USB and I've even tried jack type head phones
I've reloaded the drivers but still the system keep muting the mic.
Also in TeamSpeak I get feed back when I test the mic in options
