However this is not easy. Also, supporting "virtual" streams has been requested a couple of times as well (for example to support pass-thru line-in and suchlike). I think it makes a lot of sense to have that and it wouldn't even be hard to implement but as of now nobody wrote the code. When those "virtual" streams existed it would be up to the backend to create/destroy them and make sure the actual data flows. > Maybe this is a new challenge or direction for PulseAudio.

As I mentioned writing a backend for some hw that does hw mixing is relatively easily doable.
