hello, i am a long time macrumors reader but registered just today. anyway, let's get to the point. i have a white macbook core2duo 2,0ghz. some days ago i was watching a movie using the line out, with a pair of headset. then i put the computer to sleep, i UNPLUGGED the mini jack connector and i opened the lid of the macbook. now the internal speakers don't work anymore; don't ask me why i did it, that's how the thing went.. so far, this is what i have been trying: - i put again the computer to sleep, then plugged the headset in, then opened the lid, then removed the headset => no luck - i repaired disk permissions => no luck - i restarted the computer => no luck - i resetted the PRAM (command-control-p-r) => no luck - switched user => no luck ** side note: i can't run the apple hardware test because i don't have the cd/dvd with me (i am out of home for some days), but i am pretty sure it wouldn't help (continue reading). i have all of the updates installed, os x 10.5.6. i am downloading the combo update hoping it does something but i am without any hope. when nothing is plugged in the line-out connector, the volume CAN'T be adjusted because os x "thinks" it's controlling the digital line out, which obviously doesn't have any volume control (have a look at the attached shot); the problem is that os x should control the internal speakers, and that's because nothing is connected to the line out !!!!!!! it's like if os x went crazy because i unplugged the plug while the computer was sleeping: probably i had to ask for its permission? lol. and i am pretty sure it's a os x related problem because, after resetting the PRAM, i clearly heard the "booong" (startup chime). it's driving me nuts. thanks everyone for reading.
