Weird audio problems with MacBook

Texte:

A while ago I thought I blew up the audio chip in my macbook as I put too much signal through it. After I did that, the macbook shut down and when I booted it back up, it had no audio. The speakers didnt work, 3.5mm jack didnt work and when I went into the audio settings, there was no devices shown.
Recently I installed windows with the same result with the audio.
But when I turned it on and went into windows, the youtube video I had up last night was playing through my speakers. But when I went to try an audio test, they quit again.
I checked the Microphone input for the built in mic and it shows full bars, telling me its always picking up sound, which it is not.
The speakers also make a very quiet popping sound, only hearable when right up next to them, It doesnt change when volume is changed.
The other day, there was a red light shining or blinking (I dont remember) from out of the audio jack when it was closed and charging. Not sure if its related at all but I thought I would mention it.
If anyone knows what the heck is going on, your help would be much appreciated.
If there is any more info you need to know or any questions, Please ask!
Thanks!
