Support for Audio Playback and Capture

Eruption currently has built-in support for the following audio APIs:

• PipeWire (via the PulseAudio interface of PipeWire)
• PulseAudio

Audio support is provided by eruption-audio-proxy.service session daemon.

The eruption-audio-proxy Daemon

As of Eruption 0.1.23 it is no longer necessary to grant the root user full access to the PipeWire or PulseAudio session instance. Therefore, it is no longer required to edit configuration files. Just enable the eruption-audio-proxy session daemon, and assign a device monitor to listen on, e.g. by using pavucontrol.

systemctl --user enable --now eruption-audio-proxy.service

NOTE: Please do not use sudo in front of the command since it has to act on the session instance of systemd

Next, switch to a profile that utilizes the audio API of Eruption:

eruptionctl switch profile spectrum-analyzer-swirl.profile

Then use pavucontrol to assign a monitor of an audio device to the Eruption audio grabber.

NOTE: You have to select a profile that makes use auf the audio grabber first, otherwise the eruption-audio-proxy will not open an audio device for recording, and therefore will not be listed
