* Add a module to enable PulseAudio. It causes all ALSA applications
to be rerouted to PulseAudio. Note that this is distinct from the already existing module ‘services/audio/pulseaudio.nix’ that provides a system-wide PulseAudio daemon, which is usually not what you want. svn path=/nixos/trunk/; revision=27958
