Mic Not Working

I have a steelseries arctis pro wired headset and for some reason It isn't working in Insurgency Sandstorm. It works fine in all other games. Does anyone have a solution?

Hello @Miragee ! @Arc provided this answer in another similar thread :
"In-game VoIP is based on Steam Voice meaning that the adjustment is in Steam Voice settings accessible via new friendlist > Settings > Steam Voice".
Maybe this will help you out. Keep me updated on the situation ! Have a great day.
