Audio Is Really Low In Cubase.......HELP! (Video)

Hi, I seem to be having a really annoying problem in Cubase Elements 7.

Its only just started happening, directly after my laptop upgraded from Windows 8 to Windows 10 (against my wishes!).

Basically, it seems that all audio played within Cubase is really dull/flat/low. When I play the same audio on iTunes or Winamp its almost 2 times louder/crisper/fuller.

I am hoping its a simple thing to fix and just me being an idiot. I have uploaded a video showing the issue below:

UPDATE: I accidentally uploaded the video sideways, I have included screen grabs of the important parts below.

Any ideas on what the issue could be? I have messed around with the audio devices set-up and re-installed ASIO4ALL but with no change.

Appreciate any help!
