Is there a way to control the treble and the bass on the audio going through the headphones? My last Inspiron had an EQ that could be adjusted. If my new Inspiron 16 computer is not capable of this, I want to send it back. I love listening to music and the sound coming through the headphones is awful. Songs are mixed differently and we should have the ability to alter the bass and treble controls on our sound source. I hope I am just missing something otherwise this is a huge disappointment
