KellyAnnX3, you're awesome!
but your suggestions didn't work. the little red light still shines forth from the audio jack with all its steve jobs build it sometimes weak brightness.
what i did which worked: plug a pair of external speakers into the usb port. no, the internal speakers still don't work, but steve's little red light shineth not from the audio port and noise blairs out from the usb speakers.
so when i want head speakers, i plug'm into the audio jack; when i want external speakers, plug in the portable usb logitechs.
note to apple: build the rca audio jack more securely. and, you could program soft over-rides into the system preferences, for everything (think of it sort of like how steve jobs thought of reincarnation. he would like that. yes he would.).
