But this is not changable - at least in alsamixergui???
Played around some. It can be changed from ncurses alsamixer and kmix -
but it drops to 0 or almost 0. Unchecked skype setting of automatically
adjusting sound controls, still the same. It still drops to 0 as soon as
skype call starts.
Aha, changed the skyope checkbox before chaning mic to Communicator, and
applied the settings - now the mic volume is at max and stays there
during the call, still no sound.
With volume at 100%, I tried arecord, it sill gets silence. It outputs
constant stream ox 0x80 bytes.
