Audio Channel Volume

I'm trying to work with channel volume, but I'm having trouble pulling a floating point value from the volume request. I use:

alxSetChannelVolume(0, %value);

in order to fade out audio. However, when getting the current channel volume, I only get "1" or "0".

I use the command:

alxGetChannelVolume(0);

If the volume is 1.0, it returns "1". However, if it's less than 1 (ex. 0.95, 0.3) then it returns "0". Anyone else have this problem or know the cause? THe source didn't seem to have any problems.
