Re: release version problem

Hi,

I'm not too familiar with those compiler settings to know if that means for
100% certain that no uninitialized variables are being passed to OpenAL.

Can you give some more details about the problem that occurs in Release vs
Debug builds?  e.g When you say that sounds are not spatialized ... does
that mean that the sounds seem to play from the same location as the
listener (resulting in all sounds playing from all speakers)?  Are the
sounds at full volume or is any attenuation happening?

Hi, thanks for quick reply.

I solved it by set compiler (visual studio) settings to /RTCs (Stack
Frames) in "Basic Runtime check" for release build of my application.

but if I turn off /RTCu (uninitialized variables) the program still run ok
as long as /RTCs is set, so it doesn't need /RTCu. in that case I think its
not because of uninitialized var. what's another possibility related to
stack frames?

thanks

Hi,

Are you sure you are not passing uninitialized variables to OpenAL?  In a
debug build, variables will be set to 0 by default but a release build will
not do this - meaning the values will be completely random (and in the case
of floats and doubles they might not even be valid numbers).  Passing
uninitialized values to OpenAL could definitely mess up the 3D Audio
spatialization.

Which OpenAL device are you requesting in the call to alcOpenDevice?

hi,

I developed openAL App, on Windows 7 x64 using summer 2009 SDK from
creative, and I got problem when running release version of my application,
the sound seems not to be spatialized, but when I run the debug version of
my application, there's no problem sound is spatialized correctly.

both release and debug version are using same openal32.lib and I checked
using dependency walker both dynamically linked to Windows\System32
\OpenAL32.dll. My soundcard is Realtek HD and Creative X-Fi Titanium both
suffer from the same problem.

can anyone give me clue where should i fix this?

thank you
