For some reason whenever i'm on skype or teamspeak (or whatever it may be), the sounds like game sounds or youtube videos always go through my microphone. It's definetly not my headset because i used a different mic which was underneath my bed and had my sound playing through my headset and it still played through the microphone. The only temporary but annoying fix to this is to have my volume at ~30.
