audio: check for pulseaudio daemon pidfile
Check whenever the pulseaudio daemon pidfile is present before trying to initialize the pulseaudio backend. Just return NULL if that is not the case, so qemu will check the next backend in line. In case the user explicitly configured a non-default pulseaudio server skip the check. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20190124112055.547-5-kraxel@redhat.com
