[Openal] APCM internal representation

[Niklas Frykholm]

When I ask for the AL_SIZE of an ADPCM-compressed buffer I get back the 
size of the uncompressed data. Does this mean that the ADPCM data is 
stored uncompressed by the device? I was under the impression that 
OpenAL was able to work with the compressed data without expanding it.

Or is it device dependent? Is the data kept compressed on some types of 
devices and expanded on others?
