Ok, thanks for clarifying. What I saw was SFLPhone mic. stream which
always started all the way down. However I have been playing a little
more with it since then: It seems that if I make two consecutive calls
then sensitivity is stored between calls. I will have to do some more
testing, but right now I suspect that the problem have something to do
with unplug/replug the USB headset. Or maybee suspend/resume of my labtop.

So if I always insert my headset before I launch SFLPhone or resume my
PC it might work.
It also seems suspicious to me is that I got 2 headset listed in KDE
Device Preference under SystemSetting/Multimedia. I have never used any
other headset on this computer. Is there a way to clean up these
listings of old/nonexisting headset.
