Hi,
Yes - that is strange. The call to set the Room level to -10000 should
have removed all reverb. Is that call returning AL_NO_ERROR ? If you
would like to, then you can send me (privately off the list) your source
code and I'll try it here and I'll see what happens !

Re: [Openal] DirectSound3D and

This is very weird. When using directsound it works fine, but when using
directsound3d the following setting results in a reverb effect almost
like "hangar"
introom is ALint introom;
introom = -10000;
eaxSet(&DSPROPSETID_EAX20_ListenerProperties,
DSPROPERTY_EAXLISTENER_ROOM | DSPROPERTY_EAXLISTENER_IMMEDIATE, NULL,
&introom, sizeof(ALint));
i don't understand it, in the openal demo it does work for removing
hangar effect, but in the moment i try it myself it results in the
problem above.
Did i miss something ? Isnt there some "general option" to set
everything back to default, to unset any eax setting ?
To be sure it isnt simply my soundcard i ordered today an audigy- but
this is still very very strange to me :)
thanx,
Jochen
