Finally fixed this (but beware):
I tried getting (latest)skype and "Ubuntu 9.04/i386" and all this "pulse" crap to work but I still had no Mic.
But This quick and dirty DID WORK:
# sudo aptitude search "pulse"
# sudo aptitude purge "pulse"
(remove all the "pulse" driver packages, ...)
# sudo reboot
# In Ubuntu 9.04 -> Sound Properties -> Volume Control
-> enable Mic and adjust vol. accordingly.
(if skype is already installed just "reset" all the audio crap in skype's options back to "autoselect/defaults...", and/or alsa)
or,
# sudo aptitude install skype
Thats it. Skype works perfectly.
------------------------------------------
you could probably leave the "libpulse0", "gstreamer0.10-pulseaudio", ... client packages and skype will still work. -not sure ?
But note !, obvisouly if you use pulse (as a server,...) extensively then don't remove those.
-For me I don't give a crap !, alsa, oss, ... are more than good enough for me and I need skype.
err atleast until EKIGA get's more popular than skype -now that would be good.
