When I am not playing or I am in the main menu of Team Fortress 2, I can hear people on Ventrilo. But when I connect to a server, it stops working. Can someone suggest a solution for this issue? Thank you for your help.
Depends on the version of windows your running. if its Windows 7 or vista there is an option in your sound setting to "lower the volume of apps when mic is in use" can be found under the Sound > communication tab. check "do nothing" and that should fix that, also run both apps as administrator as well
