sound Build the X11 publish module to export PulseAudio information through X11 protocol for clients to make use. Don't enable this flag if you want to use a system wide instance. If unsure, enable this flag. Use GConf to store user preferences on streams and so on. Don't enable this flag if you want to use a system wide instance. If unsure, enable this flag. Enable OSS sink/source (output/input). Also build the padsp script to make OSS software use PulseAudio. Enable OSS sink/source (output/input). Deprecated, upstream does not support this on systems where other sink/source systems are available (i.e.: Linux). The padsp wrapper is now always build if the system supports OSS at all. Add support to dev-libs/glib-based mainloop for the libpulse client library, to allow using libpulse on glib-based programs. Use sys-fs/udev for autodiscovery of sound devices; this replaces the deprecated sys-apps/hal autodiscovery code. Allow preparation and installation of the system-wide init script for PulseAudio. Since this support is only supported for embedded situations, do not enable without reading the upstream instructions at http://pulseaudio.org/wiki/WhatIsWrongWithSystemMode . Use libasyncns for asynchronous name resolution. Enable glib eventloop support Build the doxygen-described API documentation. Makes PulseAudio use RealtimeKit (sys-auth/rtkit) to get real-time priority while running.
