This one has me a bit stumped.
It loops without clicks in Audacity and I've check the individual samples and
the start/end joint is perfect.
Do samples have to start and end with a sample value of zero in order to not
click?
I'll try to figure this one out.

I just checked this and a pitch offset of 1.0 definately reproduces the
original speed.
I don't have a frequency analyser available but my ears aren't that bad. :)
With an offset of 0.5 the frequency is definately about half of the original
pitch.

They certainly are! :)
I just did a bug test.
Here is the config :
<audiocue>
<name>sinkcue</name>
<mode>looped</mode>
<path>Aircraft/LAK-19/Instruments/ILEC_SC-7/sink-tone.wav</path>
<property>/instrumentation/vertical-speed-indicator/indicated-speed-fpm</property>
<volume>
<min>0.3</min>
<max>0.3</max>
</volume>
<pitch>
<property>/instrumentation/vertical-speed-indicator/indicated-speed-fpm</property>
<factor>0.001</factor>
<offset>1.0</offset>
</pitch>
</audiocue>
For positive values the tone increases.
For negative values the tone just loops with no pitch change.
It's definately broken but this is one of those bugs that has not popped up in
the past because no one has tried driving the pitch with a negative value
yet. :)
