Hi guys
It got an 8600 which doesn't seem to transmit much by the mic. If you blow on it very hard it makes some noise on the calling phone but no voice can be heard. It does however seem to pass some voice to the phones earpiece speaker oddly

Sounds like it's duff and looks to be a pain to replace as soldered to the board?
Iv had it apart and the port is clean and cleaning with alcohol hasn't changed anything

Any help would be much appreciated

Thanks
