It's also proved a substantial win for users to be able to use
interactive applications like alsamixer to set up the audio paths that
they need for their system rather than having to write kernel code -
it's much less of a learning curve for people for whom audio is just one
part of the system they're trying to put together.

I guess the other thing with the sort of systems that use ASoC is that
it's generally only developers who ever see the actual ALSA API in the
sort of systems that use ASoC.  Unlike desktop systems end users will
typically see a device or application specific user interface of some
kind that shows them only a very small subset of the available controls.
