i am having the same problem -- no mic and sometimes no headphone voice sound
(I am NOT using a USB headphone and mic set)
checking (TILDE) consol give this message ----
ERROR [cteamspeak_clientmanager] : : change capture device failed, error 2310,
message:could not open capture device
I have windows 10 and have checked headphones and mic settings several times...
problem seems to be an ingame sound setting BUG ...
i can sometimes get headphones working but NEVER the MIC ---
if i open the options ingame and look at sound settings it is ALWAYS set to DISABLED
in the VOICE CHAT INPUT DEVICE box --- even after being set to mic and SAVED
hope this helps resolve the problem --- completely destroys gameplay for officers
