Aug 31, 2011 at 10:45 | comment | added | jbarlow | Some small piezoelectric microphones can have megaohms of impedance so if resistance is being measured the values suggested so far may be out by a few orders of magnitude. Do you have the equipment to measure your microphone's impedance and then match that? A digital multimeter would be fine. | |

Aug 4, 2011 at 15:40 | comment | added | Kellenjb | The way I have always understood it was it was looking to see the resistance between the mic pin and the ground pin. If it is a short then the plug doesn't have a separate ring for a mic. It could be that it is looking for a higher resistance, which is why I am wondering. | |

Aug 4, 2011 at 15:10 | comment | added | roman | I've tried 1K as well we same (un)success | |
Aug 4, 2011 at 15:10 | comment | added | roman | 2.2K resistor. The question is what does it expect? | |
