If the 20dB are needed for this specific mike, and not for all mikes on
the soundcard then this looks like something we probably should cover in
the mixer logic in PA. (if it is needed for all mikes, then the alsa
init db should be fixed instead)
Please attach the excerpt of "amixer -c0" about the one switch that made
things work for you and we can add it to the PA mixer database.
