You should not test for PulseAudio via dbus, as the git version has module-dbus-protocol removed from the default installation. See http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/?id=dcb52b0844c21c7fe591ef1cfacafbda1df770f0</p></pre>

See https://bugzilla.gnome.org/show_bug.cgi?id=680779 (which is effectively a WONTFIX given the amount of time it exists).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">So, I think the correct answer is "just don't check". Checking for a process won't work, especially since you try hard to avoid spawning PulseAudio at this point. I'm afraid that you really have no choice except always assuming that PulseAudio exists together with its flat volumes.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Please either drop the "notification volume control" feature completely (even though it would technically be a regression on non-PulseAudio systems) or implement it by attenuating samples in software before sending them to PulseAudio or elsewhere.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">As for "I cannot reproduce the problem locally", I guess that you are on ubuntu or kubuntu. They disable flat volumes by default in /etc/pulse/daemon.conf for safety reasons, while the upstream default is to enable them. My opinion is that flat volumes are a security issue by themselves, but one PulseAudio developer has a link to a scientific paper (http://www.patrickbaudisch.com/publications/2004-Baudisch-CHI04-FlatVolumeControl.pdf) that he uses for defending them, and I don't really have a good weapon against that.</p></pre>
