Headphones don't work? Help please...

What’s going one here???

Opened up Cubasis again last night and now my headphones work but the iPAD speakers don’t work. It is doingexcatly the opposite as the other day…iPAD 2, volume levels are fine, 2 tracks

Guess I will try creating another project, but doubtful this will work…anyone else having this sound issue of switching between phones and internal speakers???
