I have been using Teamspeak for years so first of all I would like to specify that I know how to set up my headphones and that isn't the issue.

When I started up my computer today Teamspeak 3 wasn't making any noise, it is setup correctly and volume mixer shows the green bar that Teamspeak is should be outputting sound. I cannot hear any people or either of the two default announcers, however I can hear the text to speech announcer. I have tried reinstalling both 32-bit and 64-bit versions to no avail. Thanks for any help.
