To determine whether your Linux system is using PipeWire or PulseAudio for audio management, you can check the following methods:
Open a terminal (ctrl+alt+t) and run below commands.
For example, to check for PipeWire:
systemctl --user status pipewire
If you get Active: active (running), then you are using Pipewire and if you get Active: inactive (dead) then you are using Pulseaudio.
To check for PulseAudio:
systemctl --user status pulseaudio
You can also use blow command to find your audio server status. In the terminal run below command.
If you get “Server Name: PulseAudio (on PipeWire 0.x.xx)” like this then your are using PipeWire, ootherwise you will get “Server Name: PulseAudio” only.
You can also use this command to filter the output.
LC_ALL=C pactl info | grep "Server Name:"
By using these methods, you should be able to determine whether your system is using PulseAudio or PipeWire for audio management.
