pulsemixer-cli和curses pulseaudio混音器
pulsemixer的Python项目详细描述
脉冲施密器
Pulseaudio的cli和curses混音器
要求
Python>；=3.3PulseAudio>；=1.0
安装
Python>；=3.3PulseAudio>；=1.0pulsemixer是一个自给自足的单文件python应用程序，不需要任何额外的库。您只需手动下载pulsemixer，执行chmod +x ./pulsemixer，然后将其放在您想要的任何位置。
下面是一些更方便的安装Pulsemixer的方法：
卷曲
curl https://raw.githubusercontent.com/GeorgeFilipkin/pulsemixer/master/pulsemixer > pulsemixer && chmod +x ./pulsemixer
点
pip install pulsemixer
交互模式
如果未给出参数（除了--color和--server），则使用交互模式
交互式控件：
j k ↑ ↓ Navigation
h l ← → Change volume
H L Shift← Shift→ Change volume by 10
1 2 3 .. 8 9 0 Set volume to 10%-100%
m Mute/Unmute
Space Lock/Unlock channels
Enter Context menu
F1 F2 F3 Change modes
Tab Shift Tab Next/Previous mode
Mouse click Select device or mode
Mouse wheel Volume change
Esc q Quit
通过上下文菜单可以set-default-sink，set-default-source，move-sink-input，move-source-output，suspend-sink，suspend-source，set-sink-port，set-source-port，kill-client，kill-sink-input，kill-source-output，set-card-profile有关这些功能的详细信息，请参见man pactl
cli
Usage of pulsemixer:
-h, --help show this help message and exit
-v, --version print version
-l, --list list everything
--list-sources list sources
--list-sinks list sinks
--id ID specify ID, default sink is used if no ID specified
--get-volume get volume for ID
--set-volume n set volume for ID
--set-volume-all n:n set volume for ID, for every channel
--change-volume +-n change volume for ID
--max-volume n set volume to n if volume is higher than n
--get-mute get mute for ID
--mute mute ID
--unmute unmute ID
--toggle-mute toggle mute for ID
--server choose the server to connect to
--color n 0 no color, 1 color currently selected, 2 full-color
--no-mouse disable mouse support
--create-config generate configuration file
cli示例
Pulsemixer遵循PulseAudio的术语：
- 接收器-输出设备
- 源-输入设备
- 接收器输入-连接到输出设备的流，即接收器的输入
- 源输出-连接到输入设备的流，即源的输出。
$ pulsemixer --list Sink: ID: sink-1, Name: Built-in Stereo, Mute: 0, Channels: 2, Volumes: ['60%', '60%'], Default Sink: ID: sink-3, Name: HDMI Audio (HDMI 2), Mute: 0, Channels: 2, Volumes: ['50%', '50%'] Sink input: ID: sink-input-663, Name: Firefox, Mute: 0, Channels: 2, Volumes: ['60%', '60%'] Sink input: ID: sink-input-686, Name: mocp, Mute: 0, Channels: 2, Volumes: ['60%', '60%'] Source: ID: source-1, Name: HDMI Audio (HDMI 2), Mute: 0, Channels: 2, Volumes: ['100%', '100%'] Source: ID: source-2, Name: Built-in Stereo, Mute: 0, Channels: 2, Volumes: ['40%', '40%'], Default Source output: ID: source-output-7, Name: arecord, Mute: 0, Channels: 1, Volumes: ['40%]
默认接收器的打印音量，减少5，打印新音量：
$ pulsemixer --get-volume --change-volume -5 --get-volume 60605555
切换source-1的静音，打印静音状态：
$ pulsemixer --id source-1 --toggle-mute --get-mute
1将sink-input-663的音量设置为50，然后将sink-3的音量设置为10（左声道）和30（右声道）：
$ pulsemixer --id sink-input-663 --set-volume 50 --id sink-3 --set-volume-all 10:30
将sink-input-686的音量增加10，但不要超过100:
$ pulsemixer --id sink-input-686 --change-volume +10 --max-volume 100配置
可选。
配置文件不会自动创建。从这里复制粘贴

仍然支持旧的环境变量PULSEMIXER_BAR_STYLE。
在（例如）zsh中更改音量条的外观而不创建配置文件：
exportPULSEMIXER_BAR_STYLE="╭╶╮╴╰╯◆· ──"
