From: Arun Raghavan <git@xxxxxxxxxxxxxxxx> 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. --- src/modules/module-device-manager.c | 22 +++++------------ src/modules/module-filter-apply.c | 49 +++++++++++++++++++++++++++++++------ 2 files changed, 47 insertions(+), 24 deletions(-) diff --git a/src/modules/module-device-manager.c b/src/modules/module-device-manager.c index 0df9575..76c4c85 100644 --- a/src/modules/module-device-manager.c +++ b/src/modules/module-device-manager.c @@ -649,7 +649,7 @@ static void update_highest_priority_device_indexes(struct userdata *u, const cha } static void route_sink_input(struct userdata *u, pa_sink_input *si) { - const char *filter_device; + const char *ignore; const char *role; uint32_t role_index, device_index; pa_sink *sink; @@ -664,13 +664,8 @@ static void route_sink_input(struct userdata *u, pa_sink_input *si) { if (!si->sink) return; - /* If module-filter-apply has loaded a filter for the stream, let's not - * break the filtering.
