Oh. So you indeed have two mic jacks, but one of them is integrated as part of a headset jack.

All headset jacks I've seen so far have been 4-pin (Left headphone signal, right headphone signal, mono mic in, common ground).

As for plugging headphones into a headset jack, and still being able to use the internal mic, I wonder what to do about that. As there is no way to detect whether you plugged a headphone or a headset in that jack, I assume. So that's a generic problem, as these headset jacks are becoming increasingly common.

One could note that pin 0x15 and 0x19 share the same channel group. I wonder if that could be used to distinguish headset jacks from one headphone jack and one mic jack.

It surprised me that the internal mic stopped working at scenario D. It shouldn't - that could very well be a completely different bug.

So, no good news from me at this point. More noting that things were even more complicated than anticipated. :-/
