I posted this to the OpenAL list, but I'm sure the engineer responsible
probably is on this list, also.
First off, I'm not sure when it broke, but the new 3DMixer OpenAL (from
Apple) no longer does distance or panning volume changes (all sounds
are at max volume.)
I think it might be the new QT that came at the same time as iTunes
4.5, but I was working on other parts of the system for a while so I
never noticed until a day or so ago.
I'm the guy that pointed out the precision problem when the new OpenAL
first came out, then that was fixed, and now a similiar problem is
back, and I was wondering if something put in OpenAL to work around
that bug is now interfering when it got fixed in the mixer. My
business is guess work, if you can't tell :)
Just wondering if the core audio packages -- and especially the 3D
mixer -- were changed at all, or if anybody has tested OpenAL past the
simple test programs (I can supply a program that displays the
problem.)
This *could* be my problem, but I haven't changed that code so I'm
looking here first ....
Thanks ...
