How do I make it "What U Hear" anyway? I don't see a way to fix it.
Control Panel -> Sounds and Audio Devices
Also the same place you'd normally control PC volume.
Go into volume control for Microphone (or if you're in speaker volume click options and select properties and change to RECORDING) and select the input for your soundcard (input meaning what you would record).
On most XP computers, there should be a box saying WHAT U HEAR. It might also be called something else but I can't remember (my old computer what another name).
If it's not there you can also go into properties and see if there's a WHAT U HEAR box that's unchecked (only the checked boxes will appear).
