Hi all, Im new here and kinda new to the Mac world. Im very good with PC's but never really had the chance to mess with a Mac. I have a 2008 MacBook Air and the sound doesnt work. When you volume up or down it just shows the icon with a line through it. Like the 'Prohibited sign'. Someone asked me if it worked with headphones. No, still no sound. Someone on here suggested that I wiggle the head phone jack inside the Mac, that maybe something was hung/stuck and that didnt work either. I bought a CD/DVD external drive for it and freshly reformatted it. I did it for other reasons besides the sound not working, but in hopes that it would somehow fix my problem. Everything works perfectly except the sound and now Idk where to turn. Since its a 2008 Mac, I dont know if it would be worth getting it fixed. I was told that it costs $300 just for Apple to look at it, then once they determine the problem you pay for parts and labor. So if that is the case, then it doesnt seem smart to spend $400-550 when its not even worth that in perfect condition. Is there any other things I could try? What piece of equipment needs replaced? Could I do it myself? Was contemplating selling it, just because I never use it. I was gonna use it solely for music, but the volume not working kinda foils that plan. Please help! Thanks!
