Im a bit disappointed right now, i used to use my wireless Bose speakers normally and when i wanted i used the internal speakers, but now sound only works with the WIRELESS speakers, and the internal ones don't show up in the list of sound preferences, i have restarted the PRAM several times with alt+cmd+P+R, there is no red light because its WIRELESS, i hate to register in forums but i am really desperate and i feel stolen...$1200 for this???
Most computer problems are caused by user error, the price tag has nothing to do with any computer's problems. My university owns a multi-million dollar supercomputer, think it never has problems?
I'm just playing.
So you have no red light coming out of your headphone jack, correct?
Do the Bose speakers connect through bluetooth or by another mean? I would suggest turning off bluetooth and seeing if that helps any for the time being.
A simple restart may be all that is needed to fix your problem, which is probably caused by a driver issue.
I strongly doubt PRAM resets will do anything for you, as they only reset speaker volume according to this:

From what I gather, an SMC reset will not help either.
Did you install anything else recently on the computer?
