No sound from mike on Acer Aspire One

[Antonio M]

Running a fully updated F20 on Acer Aspire one, mike is recognized but
I get no sound from mike, even if I move cursor up and down.If I move
the cursor to the far right I see the sound bar slightly moving
Tried some tricks but no idea how to succeed in getting mike to work properly
