Hello - my iPad 2 has the "microphone-hole-clogging" problem. when I discovered that there is no sound input, I tried the vacuum cleaning trick. It restored the sound, but it is still faint. I have tried to tape the vacuum hose attachment to the iPad, so no air was leaking around the attachment,, I ran the vacuum several times, up to 1 minute. While the hose attachment is still taped to the iPad, and I speak into the attachment, the volume is quite good. When used without the attachment, sound is very faint. I thought of taking the iPad apart, but that is a scary proposal.... I am looking for any advise on this. Thanks for any info. Paul.
