There's no support at this time for configuring the maximum volume. If
you use the jack output exclusively, you could route the pulseaudio
output through some filter application in jack that would apply some
attenuation. Or you could use a ladspa sink in pulseaudio with some
simple amp plugin, and ensure that all audio is routed to the ladspa
sink.
