Somebody in the thread at some point said:
| Actually Andy explained the pin3/pin5 issue.
| From what I understand, with removed receptacle and 3-5 short, your buzz
| actually vanished, no? That's good news.
|
| For the suggested rework, that's exactly why I bought a Dremel couple
of days
| ago ;-)
| You described my plans to the smallest detail.
|
| Contrary to Andy I don't hope for eventual enlightenment somewhere in
future.
| Especially since no one than me is examining the whole issue, and I'm
sure
| there *is* *no* other way for existing devices.
| If you got the fox on the farm, you don't investigate how it's actually
| killing the chicken, rather you simply fix the hole in the fence.

Our incomplete understanding does not lead to a solution for headset mic
buzz nor any security about future designs.  One way or another we need
to penetrate those mysteries a bit deeper up to WM8753.
