Symptom & Impact

System shows no sound output and media playback is silent.

Environment & Reproduction

Ubuntu 24.04 LTS desktop with PipeWire and WirePlumber session manager.

Root Cause Analysis

Corrupted user audio state or failed PipeWire components leave no active sink routing.

Quick Triage

Run systemctl –user status pipewire wireplumber and check pactl list short sinks.

Step-by-Step Diagnosis

Inspect user journal logs and ALSA device availability to isolate service vs driver failure.

Solution – Primary Fix

Restart user PipeWire services and reset stale state under ~/.config/pipewire if required.

Solution – Alternative Approaches

Test with a clean user profile to confirm if issue is profile-specific before system-wide changes.

Verification & Acceptance Criteria

pactl shows active default sink and audio playback works across common applications.

Rollback Plan

Restore previous user PipeWire config backup and restart user services.

Prevention & Hardening

Keep PipeWire and WirePlumber package versions aligned and avoid partial audio stack upgrades.

Related Errors & Cross-Refs
