Ok, I had almost given up on this but now little update.
As i could not make skype's microphone working on debian wheezy 64 bit,
I have been using linux mint 17 for skype (4.2, everything works fine
there).
I was just trying to use skype (Now ver. 4.3) on debian once again but
this time from my wife's debian user account.
Surprisingly, microphone works just fine from her account....
i checked skype setting, pulse audio setting, looks everything is
identical to my own account...
I just don't have no clue whatsoever what is the cause of this problem...
Any thoughts, anyone?
