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:
pip install Mopidy-ALSAMixer
Or, if available, install the Debian/Ubuntu package from apt.mopidy.com.
The default configuration will probably work for most use cases.
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
- Require Mopidy >= 2.0, as we from release 1.1.0 import
gi.repository.GstAudio, which is incompatible with
gobjectwhich is used by Mopidy < 2.0.
- Don't rely on all cards which use a hardware card index to be included in the
list returned by
alsaaudio.cards(). This can happen if an audio card is disabled, but still use up a "card index", for example when disabling the builtin audio card on a Raspberry Pi. (Fixes: #8)
alsamixer/max_volumeconfig values to make Mopidy-ALSAMixer's volume scale only use a part of the underlying ALSA volume scale. (PR: #9)
alsamixer/volume_scaleto allow switching between
logscales. The default value has been changed from
cubic, which is closer to how the human ear percieve the volume. (Fixes: #3, PR: #9)
- Don't crash on epoll being interrupted by the machine suspending.
- Handle mixer controls which does not support muting. (Fixes: #1)
- Correctly require Mopidy 0.19 instead of 0.18.
- Initial release.
