[openal] A 5.1 32-bit source kills a stereo 16-bit one on OpenAL Soft

[Leszek Godlewski]

Hi,

I do keep checking for errors - a habit picked up with OpenGL development.
;) There are no errors.

The high number of buffers is my "fault" since I create one for each Vorbis
audio packet, queue it and once it's played out, unqueue it and destroy it.
There is no pooling, it was simpler to integrate Ryan Gordon's TheoraPlay
this way.

Then we're in luck, because it's a Linux port. :) I'll contact you with the
details off-list.

Thanks!

Leszek
