[Arm-netbook] A10 and all things audio

Yeah I was looking at adding the frequencies for the 23 and 59 framerates 
to see how they would perform, but...

It certainly sounds like it isn't "supposed to" be able to do more than 
stereo "right now", so there is no reason for me to check my hardware etc.

But as far as I can tell, I don't have access to the sources for anything 
audio (at that level), so I can't try to fix this myself.

So I have to decide if it is really worth investing time playing with the 
A10, if ultimately it will never be able to do what I want. I would guess 
we can make the hardware pass-through, but if we can't tinker with the 
driver, we rely on Allwinner to do it for us?

What other hardware are we looking at for a better mediaplayer? :)
