- Add "muted" class for styling the muted state.
- Add "zero-on-mute" boolean option to control slider position
when muted.
- Add "unmute-on-volume-change" boolean option to control whether
to automatically unmute when the volume changes.
The pulseaudio/slider module had partial support for a "target" config
option but changeVolume() in the audio backend was hardcoded to only
modify sink volume. This adds full source volume control:
- Add AudioTarget enum (Sink/Source) to audio_backend
- Extend changeVolume() overloads with AudioTarget parameter
- Store and use pa_cvolume for source (with mono channel default)
- Add sourceVolumeModifyCb for source volume change confirmation
- Add "target" config option to the pulseaudio module for scroll control
- Document "target" in both pulseaudio and pulseaudio-slider man pages
Usage:
"pulseaudio/slider#in": { "target": "source" }
"pulseaudio#in": { "target": "source" }
- Fix AudioBackend destructor: properly lock the PA mainloop before
disconnecting the context to prevent race conditions with PA callbacks
- Fix context leak on reconnect: call pa_context_unref() when the old
context is replaced after PA_CONTEXT_FAILED to avoid resource leaks
- Fix PA mainloop killed on reconnect (critical): PA_CONTEXT_TERMINATED
was unconditionally calling quit() on the mainloop, even during
reconnection when the old context fires TERMINATED after the new one
was created. This was killing the new context and preventing successful
reconnection, causing Waybar to appear frozen. The fix only quits
the mainloop when the terminating context is still the active one.
- Fix Wireplumber use-after-free: explicitly disconnect GObject signal
handlers for mixer_api_, def_nodes_api_, and om_ before clearing the
object references in the destructor to prevent callbacks from firing
with a destroyed self pointer.
- Fix GVariant memory leak in Wireplumber::handleScroll: unref the
GVariant created for the set-volume signal after the emit call.

Before this commit, Waybar would sometimes get into a state
where it would consume 100% of a CPU core, and the pulseaudio widget
would stop responding to volume adjustments.
In this state, the pulseaudio mainloop thread would spin, with the
counter of enabled defer events at 1, but no actual enabled defer
event in the list to get the counter back to zero after an iteration
in the mainloop.
This could happen if the unsynchronized interactions with the mainloop
thread happened to modify the list of deferred events at the same
time as the mainloop.
This commit introduces locking in accordance with the PulseAudio
documentation on the threaded mainloop:
> The lock needs to be held whenever you call any PulseAudio function that
> uses an object associated with this main loop. Those objects include
> pa_mainloop, pa_context, pa_stream and pa_operation, and the various event
> objects (pa_io_event, pa_time_event, pa_defer_event).
on sinkInfo callbacks, the default sink now has highest priority.
That fixes an issue that the volume indicator is not updated when
the changes the default output to another devices.
added PA_SINK_IDLE as valid state. PA_SINK_RUNNING is only true
if any sound output is happening on sink switch. Indicator should
also update when no sound is being played.
This commit adds a new optional config to the pulseaudio modules. It
maps sink names to other sink names so that if the current sink is a
key, the sink named by the value is considered to be the current sink
instead of it.
E.g.
"sink-mapping": {
"easyeffects_sink": "speakers_sink"
}
