This diagram looks quite pretty. I was looking into this ALSA issue
but it was rather silly, mostly because I am not qualified to fix it.
Of course I didn't know that when I started looking into it and
somehow the lack of documentation misled me -- I'll update the wiki
page in a few hours so that nobody else gets misled by it as it
happened to me.

I'll assume that you don't need my help and try to work on something
else, like help getting something upstream. If you think I can do
something that helps you for this issue please tell me or tell Andy.
