Symptom & Impact
System shows volume controls but no sound is heard from speakers or headset.
Environment & Reproduction
Appears after kernel updates, HDMI monitor changes, Bluetooth reconnects, or profile switches.
Root Cause Analysis
Incorrect output profile, muted channel, or user audio daemons not fully initialized under systemd user scope.
Quick Triage
Confirm physical output path first, then validate logical sink selection.
Step-by-Step Diagnosis
Run `pactl list short sinks`, `systemctl –user status pipewire wireplumber`, and inspect `journalctl –user -u pipewire -n 100`.
Solution – Primary Fix
Restart user audio services (`systemctl –user restart pipewire wireplumber`), select the right sink profile, and unmute channels.
