[Openal] Different audio levels between SOURCE_RELATIVE True/False

[simon at mungewell.org]

Hi,
I'm looking into switching between SOURCE_RELATIVE True/False to allow
some form of split screen functionality.

In my testing I have noticed that there is a difference in audio output
level when switching between the two modes, and by the sound of it there
is some clipping/overload happening in the engine.

A small test application is attached which shows this problem. I have a
single sound source traveling around a circle, the listener is on the
circle and will hear the source traveling past.

With SOURCE_RELATIVE False the audio output is much loud/overloaded when
the source is closest to listener.


I tried to limit/equalise this with MAX_GAIN/CONE_ANGLES, but these did
not fix the problem.

Any suggestions as to what is wrong?
Simon.
