[Accessibility] Audio framework requirements

[Marc Mulcahy]

Using Jack as a framework won't make me very happy, since as far as I know,
the audio path is completely 32-bit floating point, and therefore it won't
work on embedded platforms using fixed point processors such as ARM.

I really think that working with ALSA and ALSA lib as a start at meeting our
requirements is the right place to start.

It may be harder to convince the Jack developers of our needs, as Jack
has been designed for real-time, low latency operation, mainly for
pro-audio work. I know Ubuntu were looking at using it for part of their
audio framework, but decided against it.

As for the document, I may get a chanced to read it later and make some
comments.
