PulseAudio

Note: PipeWire is a PulseAudio replacement, consider migrating.

Installation

apk add pulseaudio pulseaudio-alsa

Alsa only applications support

Most applications on Alpine Linux are compiled to support only ALSA, foregoing linking against libpulse and the ability to dynamically switch to pulseaudio output when it finds that pulseaudio is running. Install the pulse output plugin for ALSA so applications can output to Pulseaudio.

apk add alsa-plugins-pulse

PulseAudio Utils

For pactl, which Window Managers commonly use for managing volume control, install pulseaudio-utils.

apk add pulseaudio-utils

Bluetooth

Before you can connect your device to Bluetooth speakers or headphones, you'll have to make sure pulseaudio-bluez is installed. See the Bluetooth page for more general Bluetooth installation instructions.

apk add pulseaudio-bluez

Process Priority

Pulseaudio should run with an elevated priority, because e.g. crackling or delayed audio is more annoying than a low framerate in games.

Installing the shadow package (which is compiled against linux-pam) is an easy way for the non-root user to be granted the ability to change niceness, and pulseaudio is recommended to be run as the user, rather than as root. E.g. in /etc/security/limits.d/audio.conf (and putting the user in the "audio" group):

@audio - nice -11
