MacBook Sound Card

Hello, everybody.

I have a black MacBook, 2.4 GHz, and I ran a PA through it once while trying to mix audio and it blew out the sound card and the speakers. I would like to be able to use the headphone jack again, but it doesn't work; I was wondering how I could fix this problem, preferably by purchasing a new sound card and replacing it myself if this is possible.

Thank you very much for your time.

There's no sound card in the computer. The notebooks use a DSP chip on the motherboard. If you blew the chip then the only fix is to replace the motherboard. If the DSP chip is OK but the speakers were blown, then you could replace them. Go to ifixit.com to see about getting the parts and a disassembly tutorial.

Kappy,

In that case, I'm not sure whether it's the motherboard's chip or the speakers. How can I tell if it's just the speakers that blew out? Reason I ask is because I can't put headphones through my computer anymore; the sound just doesn't work, and I don't know much about computer hardware but I'm assuming this is an internal problem with the computer, as opposed to the speakers. However, the speakers play but they've been clearly ruined, with the sound being very quiet and distorted at best, and occasionally the speakers will make weird popping noises for no reason. Thank you for your reply, Kappy, and I look forward to hearing back from you.

It sounds like a motherboard problem, but the only way to know for sure is to take the computer in for service where they have the right test equipment.
