Sorry to be late to the discussion here, but why can't you just hook up a bluetooth speaker? Personally, I have a fairly ancient MacBook Pro and just bluetooth into my home receiver. I practice that way all the time. I've tried hard wiring from the headphone jack into the audio input of the receiver, but the sound quality isn't noticeably better. Bluetooth is a lot easier.
