[Openal] Exploding Filters

[Colin Walder]

Hi Guys,

I'm experienceing some problems with the alFilterf function to set the 
AL_LOWPASS_GAIN or AL_LOWPASS_GAINHF parameters on a filter in that I get 
an 'Access violation reading location 0x00000006' 

The odd thing is that the same code works if I change alFilterf to 
alFilteri (although the value is then confined to 0 or 1). I've stepped 
through from the creation of the filter to the point where it breaks and 
all openal calls between the two succeed.

Has anyone else seen this problem and perchance know of a fix?

Cheers,

Col
