# volume_control.sh — adjust PulseAudio volume / mute via pactl

# ============================================================================

# Single entry point for media-key bindings in i3 and dwm. Shows a transient
|

# desktop notification (best-effort). Replaces the long-missing ~/volume_control.sh
|
||
|
|
# that both window-manager configs referenced.
|

|
|
#
|
||
|
|
# Usage: volume_control.sh {up|down|mute|micmute}
|
||
|
|
# up raise output volume by VOLUME_STEP% (default 5) and unmute
|
||
|
|
# down lower output volume by VOLUME_STEP% and unmute
|
||
|
|
# mute toggle output (sink) mute
|
||
|
|
# micmute toggle input (source) mute
