From 01d55ed8cdd01ca4a7b391ca61c80084bd5a6f2f Mon Sep 17 00:00:00 2001 From: Thierry Bultel Date: Wed, 5 Dec 2018 14:05:10 +0100 Subject: Adds support for bluetooth audio through bluez-alsa Implements a new bluealsa plugin to the HAL manager, reacting to the changes of the available transports. This plugin is linked with the new bluealsa.so shared library. New transports (SCO & A2DP) result in softmixer invocations of the "attach" verb, that creates the new capture (eg, A2DP capture from bluealsa ioplug PCM, SCO microphone capture), playbacks (SCO playback to a softmixer zone, and SCO output to bluealsa iogplug PCM). When a transport disappears, the hal manager calls the transaction deletion verb that will tell the softmixer to remove the created streams and associated objects.
