    MBP - No Sound?
    About a six year old (early 2008 model) 15" MacBookPro with only 2GB Ram running OS X, version 10.9.2 with all updates current. Processor: 2.4 GHz Intel Core 2 Duo. Never had an issue with sound - and for the life of the computer (I bought it new) I only used the built in speakers. About a week ago suddenly the sound is dead - both through the built in speakers and with headphones in the appropriate port. I think I have checked the VERY obvious things to check: the sound is not muted and the volume is up all the way. No sound for iTunes songs on the computer, any u-tube video has no sound, the "pings" or sounds that confirm an action are gone. I am a tech idiot! Having said that I'll guess the sound card died - however I know so little about all of this I wanted to see if you experts know of something simple to check in an effort to get the sound working again. I know this computer is struggling in processor power & memory to be running OS X - but everything works, just a little slow. I'll be replacing this with a new iMac 21 inch model in a few months so I don't want to spend a lot of money on this well worn machine. Many thanks!

    Check this link out. For starters rebooted and ran PRAM? To do this reboot and hold down Command, Option P and R immediately after the chime and keep held down until the third lot of beeps.

    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
