Deane is speaking about the audio sound of the dell laptop. Not the vArranger sound.

I forget to tell you that some laptop are coming with audio software run by defaut who 'enhance' the sound. add equaliser, etc... Maybe if you had put it back to flat, it would be better.
It's ok for the inernal speakers of the laptop, but we don't need it when you play with a mixer and a sound system.
