PulseAudio-4.0
Introduction to PulseAudio
PulseAudio is a sound system for
POSIX OSes, meaning that it is a proxy for sound applications. It
allows you to do advanced operations on your sound data as it
passes between your application and your hardware. Things like
transferring the audio to a different machine, changing the sample
format or channel count and mixing several sounds into one are
easily achieved using a sound server.
This package is known to build and work properly using an LFS-7.4
platform.

Installation of PulseAudio
In order for PulseAudio to
communicate properly with D-BUS, create a unique user. As the
root user, run:
groupadd -g 58 pulse &&
groupadd -g 59 pulse-access &&
useradd -c "Pulseaudio User" -d /var/run/pulse -g pulse \
-s /bin/false -u 58 pulse &&
usermod -a -G audio pulse
Install PulseAudio by running the
following commands:
find . -name "Makefile.in" | xargs sed -i "s|(libdir)/@PACKAGE@|(libdir)/pulse|" &&
./configure --prefix=/usr \
--sysconfdir=/etc \
--localstatedir=/var \
--libexecdir=/usr/lib \
--with-module-dir=/usr/lib/pulse/modules &&
make
To test the results, issue: make
check.
Now, as the root user:
make install
Command Explanations
find . -name Makefile.in
...: This sed changes the build system to install
PulseAudio private libraries into
/usr/lib/pulse instead of
/usr/lib/pulseaudio.
--with-module-dir=/usr/lib/pulse/modules:
This parameter ensures that PulseAudio modules are installed in
/usr/lib/pulse/modules instead of
/usr/lib/pulse-4.0/modules.
