Dependencies ============ - A Linux system using ALSA for audio playback. - ``pyalsaaudio``. Bindings for using the ALSA API from Python. The package is available as ``python-alsaaudio`` in Debian/Ubuntu. Installation ============ Install by running:: pip install Mopidy-ALSAMixer Or, if available, install the Debian/Ubuntu package from `apt.mopidy.com `_. Configuration ============= 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 scontrols`` to list available controls on your system. Example ``alsamixer`` section from the Mopidy configuration file:: [alsamixer] card = 1 control = PCM Project resources ================= - `Source code `_ - `Issue tracker `_ - `Download development snapshot `_ Changelog ========= v1.0.3 (2014-07-31) ------------------- - Don't crash on epoll being interrupted by the machine suspending. v1.0.2 (2014-07-27) ------------------- - Handle mixer controls which does not support muting. (Fixes: #1) v1.0.1 (2014-07-21) ------------------- - Correctly require Mopidy 0.19 instead of 0.18. v1.0.0 (2014-07-21) ------------------- - Initial release. mopidy-alsamixer-1.0.3/mopidy_alsamixer/000077500000000000000000000000001236650177200203565ustar00rootroot00000000000000mopidy-alsamixer-1.0.3/mopidy_alsamixer/__init__.py000066400000000000000000000013111236650177200224630ustar00rootroot00000000000000from __future__ import unicode_literals import os from mopidy import config, ext __version__ = '1.0.3' class Extension(ext.Extension): dist_name = 'Mopidy-ALSAMixer' ext_name = 'alsamixer' version = __version__ def get_default_config(self): conf_file = os.path.join(os.path.dirname(__file__), 'ext.conf') return config.read(conf_file) def get_config_schema(self): schema = super(Extension, self).get_config_schema() schema['card'] = config.Integer(minimum=0) schema['control'] = config.String() return schema def setup(self, registry): from mopidy_alsamixer.mixer import AlsaMixer registry.add('mixer', AlsaMixer) mopidy-alsamixer-1.0.3/mopidy_alsamixer/ext.conf000066400000000000000000000000651236650177200220260ustar00rootroot00000000000000[alsamixer] enabled = true card = 0 control = Master mopidy-alsamixer-1.0.3/mopidy_alsamixer/mixer.py000066400000000000000000000112221236650177200220520ustar00rootroot00000000000000from __future__ import unicode_literals import logging import select import threading import alsaaudio from mopidy import exceptions, mixer import pykka logger = logging.getLogger(__name__) class AlsaMixer(pykka.ThreadingActor, mixer.Mixer): name = 'alsamixer' def __init__(self, config): super(AlsaMixer, self).__init__() self.config = config self.card = self.config['alsamixer']['card'] self.control = self.config['alsamixer']['control'] known_cards = alsaaudio.cards() if self.card >= len(known_cards): raise exceptions.MixerError( 'Could not find ALSA soundcard with index %(card)d.
