My camera came with the microphone not soldered at all (two microphone wires were hanging above the motherboard with no sign of soldering).

That was an easy repair as soon as I figured out what's the culprit, but before I've blamed the software for this issue for two days and tinkered with the software for at least 6 hours with no result.

adryjanowski, very nice tutorial, thank you!
