From 31575f7766d6ff39665b64a3a04412eff1c39957 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Wed, 17 Jun 2009 03:45:14 +0200 Subject: alsa: rework mixer logic Completely rework mixer logic. This now allows controlling a full set of elements from a single sink's volume slider/mute button. This also introduces sink and source "ports" that can be used to choose different input or output ports with the UI. (i.e. "mic"/"line-in" or "speaker"/"headphones". The mixer paths and device maps are now configered in external configuration files and can be tweaked as necessary. --- src/pulsecore/sink.c | 144 ++++++++++++++++++++++++++++++++++++++++++++++----- 1 file changed, 132 insertions(+), 12 deletions(-) (limited to 'src/pulsecore/sink.c') diff --git a/src/pulsecore/sink.c b/src/pulsecore/sink.c index 1da094af..47792293 100644 --- a/src/pulsecore/sink.c +++ b/src/pulsecore/sink.c @@ -100,11 +100,51 @@ void pa_sink_new_data_set_muted(pa_sink_new_data *data, pa_bool_t mute) { data->muted = !!mute;
