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.
