Well, I'm reconsidering again to put some missing control again, but it makes
the things again complicated.  A still valid point is that the control would be
no volume gain but only volume attenuation.  So, you can decrease with the
"docking" volume but not more than the speaker volume.  It's a hardware
limitation, as mentioned, that it has only essentially only two (DACs) streams.

Let's see what I can do better in future...

A good point.  This can be implemented additionally.

Yes.

The automatic switch of microphone still doesn't work for your devices since I
implemented only for devices with one internal and one external mic.  In your
case, you have two external mics, so I wasn't sure whether the switching is the
right behavior.  But, thinking of the similarity with the output jacks, it'd be
more consistent to do the automatic switching with mic jacks.  It's another
TODO.

So, the urgent issue is to fix the mic of the docking station...
