Mopidy extension for ALSA volume control.
- A Linux system using ALSA for audio playback.
pyalsaaudio. Bindings for using the ALSA API from Python. The package is available as
Install by running:
sudo python3 -m pip install Mopidy-AlsaMixer
See https://mopidy.com/ext/alsamixer/ for alternative installation methods.
To use Mopidy-AlsaMixer the
audio/mixer configuration value must be set to
alsamixer in the Mopidy configuration file:
[audio] mixer = alsamixer
The default Mopidy-AlsaMixer configuration will probably work for most use cases. If not, the following configuration values are available:
alsamixer/card: Which soundcard to use, if you have more than one. Numbered from 0 and up. 0 is the default.
alsamixer/control: Which ALSA control to use. Defaults to
Master. Other typical values includes
PCM. Run the command
amixer scontrolsto list available controls on your system.
alsamixer/max_volume: Map the Mopidy volume control range to a different range. Values are in the range 0-100. Use this if the default range (0-100) is too wide, resulting in a small usable range for Mopidy's volume control. For example try
min_volume = 30and
max_volume = 70to map Mopidy's volume control to the middle of ALSA's volume range.
log. The cubic scale is the default as it is closer to how the human ear percieves volume, and matches the volume scale used in the
alsamixer section from the Mopidy configuration file:
[alsamixer] card = 1 control = PCM min_volume = 0 max_volume = 100 volume_scale = cubic
