Maybe so, but how do I disable it?
I want pulseaudio doing software volume control, and not touching the
alsa hardware controls.
You might ask why I want it disabled, that is because it is a broken
method. One cannot have a the gain control on the input to a device
linked to the gain control on the output of a device. If one ever has
two different inputs, E.g. from the CD, it just messes things up.
With the current method, all I get is noise from the speakers. If I
kill pulseaudio, I get nice sound again.
I don't understand why pulseaudio cannot see how much of a broken idea
the current method is.

Kind Regards
