Sound not working at all on certain servers

[Nihilim]

I have lost sound on specific servers, not sure what the problem is, I will try to pinpoint it. I think it may be my headphones, although it worked before fine, after I downloaded the newest Team Speak version I suddenly have been having sound issues with the game. I hear people on TS or Vent but no in game sound. My TS seems to crash a lot where I hear everyone but they can't hear me, usually happens after 20 min of use. All sound drivers up to date, my headphones are Triton. Dunno what else it can be. Been told to reinstall the game as a possibility but trying to avoid that...

I have a similar issue except ive been using teamspeak for a long time, no crashes for me though. I can usually change servers and it will be fine for a different server but when i go back to the one i lost it in, it will still have no sound. Sometimes as well i might add, I can only hear the sounds my person makes whereas the rest of the people on the map are just completely silent.
