Any idea why going on garageband would completely remove all sound from a macbook??

[Rarran]

Hi,
I'm a mac newbie. Just got a brand new macbook, plugged in a guitar to record some music and the sound went haywire. Re-started and all of a sudden I can toggle volume, but no sound. iTunes produces no sound. Neither does any website. Spent an hour talking to techsupport and tried various checks, restarts and so on, but no joy.
Apparently now I have to head miles out of town to an apple store and take my macbook there, where I'll have to pay for any repairs?!

This isn't why I left the world of windows! lol

Any ideas or advice would be greatly appreciated.

GarageBand & sound

Hi,

Any ideas or advice would be greatly appreciated.

Rarran, you might check your "Audio Midi Setup". I once lost all sound from running some game, and had to reset the format in AMS to 44100.0 Hz. Game had changed it and i had no sound out at all. Just a chance yours might be effected as well.

No dice

Thanks for trying man, but that was one of the things tech had me try, they're stumped.
