We put the plugin and it's configuration usually in the same # package, but that's problematic when the configuration file is related to # multiple plugins, as is the case with the pulse, oss and maemo plugins. In # case of the pulse plugins, we have a separate alsa-plugins-pulseaudio-conf # package that depends on all the pulse plugins, which ensures that all plugins # that the configuration references are installed. The oss and maemo # configuration files, on the other hand, are in the respective pcm plugin # packages. Therefore it's possible to install the configuration file without # the ctl plugin that the configuration file references. This is unlikely to # cause big problems, but some kind of improvement to the packaging could # probably be done here (at least it would be good to handle the different # plugins in a consistent way).
