So - this is mostly to satisfy your curiousity, to show how far I am with the framework. I don't know how much more it offers compared to the diff scripts you run at your side, so it's up to you whether you actually want to commit this now, or whether you want to wait for me to develop more tests (jack plug/unplug, set controls and such).

I see no reason to avoid committing :) It's always good to keep in sync.

Applied both patches now. Thanks.
