Hi!
On my computer both microphones are not working but playback and all other
audio stuff seems to work. I'm not sure if the microphones ever worked with
alsa because I never tried it before. On windows they are working as
expected, hence the hardware seems to be OK. Is there anything I can do to
further debug this? Is it a known problem?
Below you can find more information about the hardware:

Doesn't work with 2.6.18 as well.
