Has your machine sustained any damage? Think back, it could just be a drop or liquid spill.

We need to do some diagnostics to determine what's wrong.

Go to system preferences - sound - move the balance toggle back and forth tell me what you hear. Plug earphones in and do the same.

The speakers on the MacBook often sound like they are blown, particularly the left speaker. The defect is quite noticeable if you reboot the machine with the volume turned all the way up. The Apple startup sound will cause the speaker to pop and crack everytime.

If a high frequency squeal emits from the left side of the computer, near the keyboard. Disabling the second core of the processor or running a program that prevents the processors from being idle will eliminate this sound (like PhotoBooth). Apple acknowledges the issue. http://support.apple.com/kb/TS1823?viewl... AppleCare representatives have been instructed to tell customers the noise is part of normal operation and is not a defect
