Environment & Reproduction

Root Cause Analysis

PipeWire or WirePlumber session services are inactive or misconfigured.

Quick Triage

Check user-level service states and default sink selection.

systemctl --user status wireplumber

Step-by-Step Diagnosis

Inspect logs for ALSA profile and graph negotiation failures.

Solution – Primary Fix

Restart user audio services and set a valid default sink.

systemctl --user restart pipewire pipewire-pulse wireplumber

Solution – Alternative Approaches

Reinstall core audio packages if service files are damaged.

sudo apt install --reinstall pipewire wireplumber
