[Openal-devel] Flightgear and Doppler effect

[Maik Justus]

Hi Daniel,

thank you for your answer. I am using the "Generic Software" device. I 
have linked to the lib out of the actual SDK (the lib is dated 
02-aug-2005). Meanwhile I found a similar thread in the archive, which 
is younger than the lib. Is there a newer version of this file?

I just got the info, that even on Linux (no idea, which device and the 
exact version of the OpenAL1.1 lib) is a problem with the Doppler sound 
in some sound configurations, but due to fact, that OpenAL-Doppler 
effect is not working at all for me, I can not debug that (unlikely but 
not impossible, this second effect is related to a bug in my code).

Maik
