You are not getting audio because DVI does not export sound, so when it gets converted to HDMI (which does carry sound), it doesn't matter as there is no sound to convert.
Like mentioned above, you can get a 1/8 to RCA cable (Cheap),
or one of these http://www.mycablemart.com/store/cart.php?m=product_detail&p=374 along with an optical cable to plug in.
Are you saying that the 1/8 mini jack has an optical jack inside of it?????. If so that is way cool and something that I did not know. Will this allow you to have 5.1 surround sound?
Yes, and Yes!
And yes, it is very coolIt just needs a special cable like THIS one:

It's called a 'mini toslink' but Apple is the only company I know that uses it.
Just to be clear, we are talking about the ear phone jack on the side of the MBP????
