Windows 7 has separate user-visible mixers. I don't know about under the
hood. I have separate mixers for my HDMI Audio, and for the normal HDA
Audio (headphone/mic jacks). Each has a master level, and then the per-app
volume controls.
This, to me, seems like the right approach. In Haiku, I even get two HDA
Audio nodes on the left panel (although the HDMI audio itself is still
broken/unsupported). So in theory, Haiku should be able to do all of this.
What would be neat, however, is to be able to drag'n'drop an output from
one device mixer to the other.
If you wanted a UI like Dane's mockup, you'd have to provide the master
controls from all audio outputs on that mixer pane; and then you'd need the
mixer to no longer belong to a device node as it currently is.
Anyway, most of the issues here seem to be mostly UI-centric to me (for
example, the Media prefs doesn't handle display of multiple mixers
properly).
