pamixer 命令

常用示例

说明

pamixer controls PulseAudio and PipeWire volume from the command line. It provides simple volume management for scripting and keybindings. Volume operations work as percentages. Increase and decrease adjust relative to current level. Set-volume applies an absolute percentage. Mute control toggles audio without changing volume level. The toggle command provides single-key mute/unmute functionality. Sink selection targets specific audio outputs when multiple exist. Default sink is used when not specified. Sources control microphone and input levels. Allow-boost permits volume above 100%, useful for quiet audio sources. This may cause distortion with already-loud content. The tool works with both PulseAudio and PipeWire (through its PulseAudio compatibility layer).
