Finally, is there a way to make an operation dependent on two properties in an xml sound file? - I'd like to make a further drop in engine volume dependent on both /sim/current-view/internal AND /sim/general/headphones (or something like that) being true.

If you mean, make and audio *event* dependent on two properties then you will have to use conditions (See docs-mini/README.conditions)


If you want the pitch and/or volume changed based on two properties you can define two sections, each reacting to it's own property:

   <volume>
    <property>/engines/engine/mp-osi</property>
    <factor>0.00375</factor>
    <min>0.15</min>
    <max>0.5</max>
   </volume>
   <volume>
    <property>/orientation/alpha-deg</property>
    <type>log</type>
    <min>1.0</min>
    <max>1.5</max>
   </volume>
