Nice script. I did so and used "diff" to compare the two.

This way, I saw, that not only "Microphone" disappeared but "Capture" 
was added.

So I pushed "Capture" to maximum volume and unmuted the channel and... 
now my microphone works!

IMHO it is a bit confusing if "Microphone" is renamed to "Capture" ;)

And another thing, that seems to be misnamed, is the "Internal 
microphone boost" setting. If an external microphone is plugged in, then 
this setting also applies to this microphone. So maybe it would be 
better to name it "Microphone boost"?

Thank you for your help.
