MacBook - Windows 7: squeaking sound with closed lid
Hello All,
I have a MacBook (alu, late 2008) with Boot Camp (v4.0) and Windows 7 (32bit) installed.
Whenever I close the lid and run on a external display, there is a loud squeaky sound coming from the speakers.
I found out that the sound stops when I lower the volume to about a half or below.
Also it has something to do with the mic being on the top of the lid (next to iSight camera). When the lid is open, there is nothing in fornt of the mic, hence no annoying sound is coming out of the speakers. However, when i close the lid, the mic gets covered with the bottom aluminium case and the speakers start to squeak.
This does not happen in OSX (Lion), only in Windows 7.
Does anyone know how to resolve this ?
