This is something I looked at, without much progress though beyond a set
of initial patches to make use of the media controller API. There were
two issues:
- one was to agree on a syntax/format for the (binary) topology
information exposed by the kernel.
- the main issue was really how to link a user-visible volume slider to
a specific or group of volume controls. A number of people have tried
this before in other contexts and it's really hard to do based on
topology information only.
But yes a good topic to re-discuss
