Mac Os Openal Issue (Maybe A Beginning Of Solution ?)

[Ethan]

Hello,

After, have debug the program, it seem that there are a problem with the "define function AL_CHECK"

who use al_check().

#define AL_CHECK al_check(__func__,__LINE__)

static void al_check(const char* caller, int line)

{

ALenum err = alGetError();

if(err != AL_NO_ERROR)

al_ReportError(err, caller, line);

}

For what I understand, before take the last error, it is necessary to clear the error state.

So I have called alGetError(), beforeALenum err...

And now I have the sound, in main menu, and when I play.

But the sound is not perfect.

I launched the game in windowed mode.

But now there are a new issue, when I return to the main menu, and I quit, I have this error:

h_mgr.cpp(659): Function call failed: return value was -100021 (Invalid Handle (argument))

What do you think ?

Than you

Ethan.

Do you mean you've changed it to

static void al_check(const char* caller, int line)
{
   alGetError();
   ALenum err = alGetError();
   if(err != AL_NO_ERROR)
        al_ReportError(err, caller, line);
}

or something like that? In that case the first line will capture any real error that has occurred, and then ignore the return value, and the "ALenum err = alGetError()" will always return no error because the error state was cleared. So this will just hide any real errors that occur - I don't think it'll ever really fix anything. (We should never trigger any OpenAL errors so it shouldn't be necessary to clear the error state at all, as far as I'm aware.)
