[pulseaudio-discuss] [PATCH 2/3] module-filter-apply: Don't implement policy in module-device-manager
arun at accosted.net

Fri May 6 08:13:26 UTC 2016
From: Arun Raghavan <git at arunraghavan.net>
This adds an ignore mechanism to module-device-manager and uses that
from within module-filter-apply, rather than having m-d-m have knowledge
of anything related to m-f-a.
This does make m-f-a know about m-d-m policy, but it should be possible
to completely remove this in the future, but having m-d-m be more
intelligent about dealing with filters.
