[Qemu-devel] [PULL 1/5] audio: pa: Set volume of recording stream instead of recording device

[Gerd Hoffmann <kraxel@redhat.com>]

From: Peter Krempa <pkrempa@redhat.com>

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.
