I have had Teamspeak for a while now and it worked perfectly. But recently I bought a new pair of headphones and lost all sound to it, I have made sure that my headphones and teamspeak are not muted, I have went in my settings and made sure everything is turned up. I have had no troubles with other games and videos. My headset is Sades SA-903. I use teamspeak quite regularly and would love to get it working again
