@ -11,6 +11,20 @@ Parameters:
Note: If the left and right channels have different volumes, the limit might not be reached exactly.
* pulseaudio.showbars: 1 for showing volume bars, requires --markup=pango;
0 for not showing volume bars (default)
* pulseaudio.showdevicename: If set to 'true' (default is 'false'), the currently selected default device is shown.
Per default, the sink/source name returned by "pactl list sinks short" is used as display name.
As this name is usually not particularly nice (e.g "alsa_output.usb-Logitech_Logitech_USB_Headset-00.analog-stereo"),
its possible to map the name to more a user friendly name.
e.g to map "alsa_output.usb-Logitech_Logitech_USB_Headset-00.analog-stereo" to the name "Headset", add the following
bumblebee-status config entry: pulseaudio.alsa_output.usb-Logitech_Logitech_USB_Headset-00.analog-stereo=Headset
Furthermore its possible to specify individual (unicode) icons for all sinks/sources. e.g in order to use the icon 🎧 for the
"alsa_output.usb-Logitech_Logitech_USB_Headset-00.analog-stereo" sink, add the following bumblebee-status config entry:
pulseaudio.icon.alsa_output.usb-Logitech_Logitech_USB_Headset-00.analog-stereo=🎧
* Per default a left mouse button click mutes/unmutes the device. In case you want to open a dropdown menu to change the current
default device add the following config entry to your bumblebee-status config: pulseaudio.left-click=select_default_device_popup
