audio: pa: Set volume of recording stream instead of recording device

Since pulseaudio 1.0 it's possible to set the individual stream volume
rather than setting the device volume. With this, setting hardware mixer
of a emulated sound card doesn't mess up the volume configuration of the
host.

A side effect is that this limits compatible pulseaudio version to 1.0
which was released on 2011-09-27.
