[alsa-devel] [PATCH] ascenario: Add dump and configure utils for ascneario.

[Stefan Schmidt]

From: Stefan Schmidt <stefan at slimlogic.co.uk>

ascndump is used to dump the kcontrols in a syntax that can be used with ascnctl
later. To list and set scenarios you can use ascnctl. This patch depends on the
ascenario infrstructure to be merged in alsa-lib.
