File 0010-alsa-ucm-Support-Playback-CaptureVolume.patch of Package pulseaudio-13.0
From 3dfccada466bef64f73ef9be3d94eaee7b6f9a60 Mon Sep 17 00:00:00 2001 From: Arun Raghavan <git@arunraghavan.net> Date: Tue, 3 May 2016 18:22:10 +0530 Subject: [PATCH] alsa-ucm: Support Playback/CaptureVolume This allows us to support the PlaybackVolume and CaptureVolume commands in UCM, specifying a mixer control to use for hardware volume control. This only works with ports corresponding to single devices at the moment, and doesn't support stacking controls for combination ports. The configuration is intended to provide a control (like Headphone Playback Volume), but we try to resolve to a simple mixer control (Headphone) to reuse existing volume paths. On the UCM side, this also requires that when disabling the device for the port, the volume should be reset to some default. When enabling/disabling combination devices, things are a bit iffy since we have no way to reset the volume before switching to a combination device. It would be nice to have a combination-transition-sequence command in UCM to handle this and other similar cases. PlaybackSwitch and CaptureSwitch are yet to be implemented. --- src/modules/alsa/alsa-sink.c | 70 +++++++++++---- src/modules/alsa/alsa-source.c | 68 +++++++++++---- src/modules/alsa/alsa-ucm.c | 165 +++++++++++++++++++++++++++++------- src/modules/alsa/alsa-ucm.h | 26 +++++- src/modules/alsa/module-alsa-card.c | 4 +- src/pulsecore/core-util.c | 26 ++++++ src/pulsecore/core-util.h | 2 + 7 files changed, 295 insertions(+), 66 deletions(-) diff --git a/src/modules/alsa/alsa-sink.c b/src/modules/alsa/alsa-sink.c index 4b46708ce4a3..08d4d1f38b80 100644 --- a/src/modules/alsa/alsa-sink.c +++ b/src/modules/alsa/alsa-sink.c @@ -1598,7 +1598,7 @@ static void sink_set_mute_cb(pa_sink *s) { static void mixer_volume_init(struct userdata *u) { pa_assert(u); - if (!u->mixer_path->has_volume) { + if (!u->mixer_path || !u->mixer_path->has_volume) { pa_sink_set_write_volume_callback(u->sink, NULL); pa_sink_set_get_volume_callback(u->sink, NULL); pa_sink_set_set_volume_callback(u->sink, NULL); @@ -1633,7 +1633,7 @@ static void mixer_volume_init(struct userdata *u) { pa_log_info("Using hardware volume control.
