Hi!
Did anybody wrote a small JOAL-Appliction which shows all Informations about the OpenAL implementation of the executing environment?
I have tried to but I must have forgotten something, because the results looked very strange to me.
That was my code:

}
} else devSpecs = "none";
print("Available Devices: "+devSpecs);

}
public static void main(String[] args) {
OpenALInfo oali = new OpenALInfo();
oali.initOpenAL();
oali.showALInfos();
System.exit(-1);
}
} |
My results were:
Version: OpenAL 1.2.1 (I thought 1.1 is the latest ?)
Renderer: Software (makes sense)
Vendor: Any (strange but ok)
Extensions : (no result...)
Available Devices: none
ALC Extensions : null
Available Capture Devices: none
It looks like the AL Context hasn't been created right...
Is there a problem with the code, my OpenAL-implementation or my hardware?
Greetings and thanks
Chris
