My feeling is that kernel based scenario really should be minimal to non
existent depending upon machine. If it has to be implemented then it
must be consistent across all devices (probably worth creating a
sound/core/scenario.c for others to use).

Imho it's far better to do most scenario in userspace due to increasing
driver complexity and slow driver scenario development speed (remember
the OSS driver pain involved with this). Userspace will additionally
give us a consistent API for applications and hopefully much better
adoption (esp if merged into alsa-lib / salsa).

Btw, I'll be releasing a new version of the ALSA scenario library early
