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

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 :-?
