# Prerequisites
- working kernel with alsa audio
- `opt/alsa-utils` will be installed by default as a dependency and needs to be configured by the user
- currently, pipewires default config makes use of `opt/alsa-ucm-conf`, consider installing that alongside the default dependency `opt/alsa-utils`

## Optional prerequisites
- pipewire needs pulseaudio to be built with xorg-libxtst around to have the pulseaudio portal available
- `prt-get depinst xorg-libxtst && prt-get update -fr pulseaudio`
- please look at `contrib/pipewire/Pkgfile` for further optional dependencies listed and rebuild the package after installing new optional dependencies
- pipewire needs pulseaudio to be built with xorg-libxtst around to have the pulseaudio portal available
- `prt-get depinst xorg-libxtst && prt-get update -fr pulseaudio`
- `contrib/rtkit` and a realtime compatible kernel to help with latency, add your user to `rtkit group` to be able to make use of it

# Running pipewire
`pipewire` will always leverage `alsa`, so you should configure that first. Use `alsactl store` to store those settings, and configure `/etc/rc.conf` to start `/etc/rc.d/alsa` by default. While you are in `rc.conf`, make sure you start `/etc/rc.d/dbus` too, if you haven't already.
