Hi, I bought this computer used and when the guy showed me the computer it worked with some JBL external spkrs, but the internal spkrs would not work. Once I got the laptop home, it would not work with my Sony spkrs, and just gives me faint sound through some Apple headphones.
I can not change any settings in Sound Options unless it detects something connected in the headphone jack, and I can't change volume setting from the menu bar (nothing is muted).
I tried Command-Option-O-F (reset firmware) & Command-Option-P-R (never heard a chime) & neither worked. Can my system really be gone even though I heard sound coming from the external spkrs when I got the laptop?
Any help is greatly appreciated?
