PulseAudio
Depending on which applications you use, you might need to provide PulseAudio
with a D-BUS session bus (e.g. via dbus-run-session
) or a D-BUS system bus
(via the dbus
service).
For applications which use ALSA directly and don't support PulseAudio, the
alsa-plugins-pulseaudio
package can make them use PulseAudio through ALSA.
The PulseAudio package comes with a service file, which is not necessary in most setups - the PulseAudio maintainers discourage using a system-wide setup. Instead, PulseAudio will automatically start when needed.
There are several methods of allowing PulseAudio to access to audio devices. The
simplest one is to add your user to the audio
group. Alternatively, you can
use a session manager, like elogind
.
