I meant that instead of having multiple backends we could follow the
route NSSound took and add a backend that uses libao to Cynthiune. That
would reduce the number of needed backends to maybe a couple.

If NSSound's libao backend compiles and works on a given plateform we
will know that a libao backend for Cynthiune will also work on this
plateform.

I will give it a shot and see if I can make a libao backend works.
