ASIO4ALL is quieter than primary sound driver

I'm using FL studio and when I run the ASIO4all driver, it is significantly quieter than the primary sound driver. When I output a test song though, both are the same levels, so I assume it has to do something with the mixer (I'm using windows 7) But the asio4all doesn't show up in the mixer when I'm using it. Any advice?

Never mind, I figured out the problem. If anyone else has this problem, check to see if you have "Dolby Advanced Audio" on. Mine was on and it was amplifying my computers regular sound, but when ASIO was being used it was at normal volume. :S So I just disabled DDA.
