Perhaps I should present our (Murphy[1] team at Intel) plans for the
routing infrastructure and policy in PulseAudio? It might be relevant
for this, although effect offloading and firmware handling is not
something that we have thought about. Even without effect offloading and
firmware handling the routing system has to deal with use case
prioritizing and constraints regarding what audio paths are available
and what paths can be used simultaneously.

BTW, there will also be a Murphy meeting/BoF on Wednesday at 13:00 in
the Dunvegan room at the Sheraton hotel next to the conference center.
Anyone who's interested in Murphy is welcome to attend. I'd expect there
to be a general overview of Murphy from Janos, and I should present the
status and plans for the routing work in PulseAudio (perhaps in more
detail than in the audio miniconf). Other than that, there's not much
else planned, just general Q&A with the Murphy developers (Janos Kovacs
and Jaska Uimonen will be present - too bad they couldn't make it to the
audio miniconf).

[1] Murphy is the resource policy daemon in Tizen IVI,
