Its crazy you mentioned this because I just went through the binds and changed the speak option to "T" so far it looks like its working fine, but still when I hit caps it mutes all sounds and I have to restart the game to get sound again. My caps must just be cursed in DayZ considering its the only program that makes it act up. I tried everyone's suggestions so far and still no luck with getting caps not to mute. If you have any more advice please send it my way, I will continue troubleshooting and post back if I find a fix. Thanks all!
