I suspect there's a problem with the microphone cable.

I just noticed today -while on a Skype call- some static sound registering while using the build-in microphone of my MacBook. I installed LineIn (in order to have some microphone pass-through) and found out that while tilting the display, the static was becoming worse or disappearing altogether on certain angles. Hence, I am suspecting damage at the microphone cable.

Is there any way of fixing this issue, without taking the whole computer apart?

Also, the static seems digital in texture; is there a chance it's not the cable, but something else? Mind you, did all software/firmware tricks I could think of.

I could also attach a recording of the issue.

So, in case I will have to replace the microphone cable, is there a specific part number available for the microphone cable (I cannot find a replacement cable on ifixit), or am I out of luck in fixing it myself and I should send the MacBook for service?

From what you are describing, this definitely sounds like a hardware problem. Unfortunately, if it is a non functioning cable issue, you will likely have to take it apart.

You'll have to open the MacBook and check the microphone cable connections to the logic board and to the iSight camera. Here's a replacement kit you can buy for cheap if the cable is damaged:

I did not. After a few days, the issue seems to have resolved itself, although I am sure it will eventually reappear...

My microphone has never worked. mid-2007 Macbook. I brought it to the AppleStore in February 2013, and am told that the microphone cable #922-7888 is "split". $7.95 part $39 hardware repair labor. I do not know how a microphone cable splits, other than Apple damaged it when they replaced the splitting plastic on the lower case a few years ago.
