FWIW I have tried something similar. I put a small (100 Ohm IIRC) resistor between MIC and GND, that doesn't help at all though. It just makes things worth. If you think it's more likely to work I can try a short everything or a completely different approach (still have two 2.5mm jacks lying around) if you want. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFI1Ao70JXcdjR+9YQRAu1EAJ0Vk1C7UqJXsX7qOA4xwAVM8kuj4gCeJlxM af9sKgB6Ld5BA574gEBhj2o= =KhtH -----END PGP SIGNATURE----- _______________________________________________ hardware mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/hardware
