He, he... what a couple of "dumbs" that we are. Okay, lesson learnt: now 
we know two ways for enabling the Mic/Capture input from the console.

Sure, it's far from an intuitive way for a user to guess how to toggle on/
off the selected input. Although "Help" (F1) can indeed "help" to find 
out ;-)

Good to know it is working now for you.

Mmm... no idea but Google seems to provide some hits (keyword: "mic 
output speaker linux") but I can't find an easy way to get this from my 
netbook. I guess there should be an additional "output" control for the 
Mic and selecting this as the default "output" should create the loop but 
I can only see one general output listed in alsamixer.

Wait... I just have discovered that by running alsamixer and selecting 
the real sound card (Intel HDA) instead PulseAudio (which is selected by 
default) now I have lots of controls available: Master, Headphone, 
Speaker, PCM, Front Mic, Mic, Beep, Capture, Digital and Internal Mic. 
How can that be? Is PA is monopolizing the audio I/O? I'm stumped :-?
