I've just recently been experiencing a slightly humorous bug whereby when I join a TeamSpeak server (I'm using voice.teamspeak.com for testing) all audio from my PC becomes higher pitch. This only ever happens once I join a teamspeak server and not when I just leave it open. The only way I have found to revert this effect is to restart the computer.

I am currently running:
  • Teamspeak
  • Ubuntu 14.04 LTS
  • A Focusrite Solo sound card
