Problem was intermittent (every few months). Speakers would usually be back on the next day. This time it has been 3 days and they are not on. Only thing I have tried is pulling the fuse (looks fine - not broken) for the radio as there isn't one for the speakers.

Audio plug in the back of the radio may be loose.

Thanks for the help. The radio magically began working again before I could research the plug. I'll put this first on my list for when it goes out again.
