No Sound From Built In Speakers Options

[ourmanflinty]

Sounds like poor contacts, dirty contacts, high impedance, dry joint ( poor solder connection ) etc. I know on ibooks there is impedance detection on the minijack output, this could be getting confused by dirt/oil/residue which would affect the output driver. Try a contact cleaner, non greasy.

Otherwise it's software based and a reset might do it.

If the minijack has got an bad solder connection then it'll need opening up etc big bucks!

Thanx for the advice. A reset won't harm any content on my harddiskdrive, right? By the way, how do I do a reset?
Thanx, Atahualpa
