I tried to use Skype (4.1) with Polycom Communicator C100S. Audio
output works fine but mic seems to be dead, although it is set to
capture and volume is even max. Dmesg tells the following two kinds of
"cannot get freq at ep ..." messages while trying to use it.
Linux is 3.12-rc2 but I saw the same behaviour a couple releases ago
when I first tried it.
I am not subscribed to alsa-devel, please CC in replies.

Please show the output of "amixer scontents" for this device.

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.
