[pulseaudio-discuss] [RFC PATCH 1/4] Integrate UCM basic functions into alsa card module
feng.wei at linaro.org
feng.wei at linaro.org
Fri May 18 03:06:45 PDT 2012
From: Feng Wei <feng.wei at linaro.org>
UCM basic functions will provide another way to handle the alsa mixer and controls.
That means alsa card module will make use of alsa ucm configurations provided by
various audio systems instead of mixer and paths configurations provided by PA.
PA profiles come from UCM verb, PA sinks/sources and ports come from UCM devices.
A new "use_ucm" module arg is added to enable the UCM branches, in case the proper
UCM configurations are found. Or we will still fall through to the original way.
