Symptom & Impact

System produces no sound despite detected audio hardware.

Environment & Reproduction

Can occur after updates or conflicting PulseAudio remnants.

pactl info
wpctl status
systemctl --user status pipewire wireplumber

Root Cause Analysis

PipeWire session manager state or device profile selection is broken.

Quick Triage

Verify user services and default sink assignment.

systemctl --user status pipewire-pulse
pactl list short sinks
wpctl status

Step-by-Step Diagnosis

Inspect user journal for PipeWire and WirePlumber errors.

journalctl --user -u pipewire -u wireplumber -n 120
wpctl inspect @DEFAULT_AUDIO_SINK@
aplay -l

Solution – Primary Fix

Restart audio services and reset user PipeWire state cache.

systemctl --user restart pipewire pipewire-pulse wireplumber
rm -rf ~/.local/state/wireplumber
systemctl --user restart wireplumber

Solution – Alternative Approaches

Reinstall PipeWire stack packages if binaries or configs are corrupted.

sudo apt install --reinstall -y pipewire pipewire-pulse wireplumber

Verification & Acceptance Criteria

Audio playback works from test source and default sink is healthy.

speaker-test -t sine -f 440 -l 1
wpctl status
pactl info

Rollback Plan

Restore previous user config from backup if custom routing is needed.

rsync -a ~/backup/wireplumber/ ~/.local/state/wireplumber/

Prevention & Hardening

Avoid mixing unsupported PulseAudio tweaks with PipeWire defaults.

systemctl --user is-enabled pipewire wireplumber
apt policy pipewire
