I'm on Windows 7 using a Sennheiser PC360 headset.
Today my microphone just stopped working (it was working fine yesterday, no settings changes). I have tested the headset on several computers and on different audio jacks and it is all the same issue. When I talk into the microphone, nothing can be heard. But when any sounds from my computer are made (ie : clicking, youtube, itunes, ANY sounds being made from the computer) it can be heard by everyone.
LONG STORY SHORT : My headset is taking the sound I'm hearing (like youtube) and is playing it to people in a skype call/ventrilo. No one can hear my voice.
I feel like this is an issue with crossed wires, but I need some opinions. THANKS!
