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. -- Meelis Roos (mroos@linux.ee)
