Thanks for the report. I've fixed this another way since the same 
problem would still existed if --no-sound was specified. I've now 
delayed loading of the voice file until /sim/sound/working is set to 
true. This fix is in CVS.

[Flightgear-devel] Broken ATIS Init due to late OpenAL Initialization.

[Zebediah C. McClure]

Greetings,

In Flightgear 2.0 and CVS on Gentoo linux, ATIS transmissions were not 
working properly. 

Upon examining the code, I noticed that ATIS was initialized in the 
fgIdleFunction with all the other subsystems, yet fgInitSoundManager() isn't 
called until inside the main loop.  Since ATIS is setup before OpenAL, when 
ATIS attempts to load the default.wav file, it fails when it hits the 
if(!_working) trap in the audio load function.

I have worked around this problem by spamming the #ifdef 
ENABLE_AUDIO_SUPPORT block of code from the main loop into main.cxx just 
before  fgOSMainLoop(); is called.  This init's OpenAL before the other 
subsystems.

I'm aware that this is an awful and piggy solution and am willing to 
write a proper patch, but I don't understand how sound init is supposed to 
work, where, and when.

Hope this helps someone, I've seen s few unresolved reports of this 
issue 
around on the 'net.

Cheers,

Zeb McClure
