pulseaudio is a networked sound server for Unix-like operating systems and Microsoft Windows. It is intended to be an improved drop-in replacement for the Enlightened Sound Daemon (ESOUND). Pulseaudio will need a pulse group/user to run. You can add one with # groupadd -g 216 pulse # useradd -u 216 -g pulse -d /var/lib/pulse pulse or something similar. See http://slackbuilds.org/uid_gid.txt Pulseaudio requires libatomic_ops, libsamplerate, and libsndfile. It will also make use of jack-audio-connection-kit. All of these dependencies are available at SlackBuilds.org.
