This all sounds pretty interesting, but I also assume there could now be two types of Mic problem. Maybe software, maybe hardware.

For example, I've not been able to get my Mic working at all, and I didn't use the charger until sometime after I found the mic problem.
I do hope that these theories are right and most of the issues can be solved somehow. But unless I'm doing something odd, I can't seem to restart and get it back. Even after charging with usb etc.
Oh well, is just my bad luck. Glad you guys are looking into things quite deeply though. It's good to see the community come together like that.
