Audio Wizard — Fix No Sound Free
Describe your symptom — no sound, dropped channel, buzz, weak bass or clipping — and get a guided verdict plus clear fixes. Free in your browser, no download.
Protect your hearing. Start at a low volume. Never raise the volume to make a tone audible. Levels are shown in dBFS, relative to full scale — not SPL.
How it works
Interactive symptom-based decision tree with embedded signal generators for left/right balance, phase coherence, and low-frequency resonance sweeps.
What the Diagnostic Wizard Does
Audio problems are rarely mysterious when broken down systematically. Most audio issues stem from one of four domains:
- Software & Routing: Incorrect output devices selected in operating systems, muted browser permissions, accidental balance panning, or digital volume attenuation.
- Cables & Connections: Intermittent 3.5mm TRS contact, broken solder leads inside strain reliefs, loose optical connectors, or ground loop hum.
- Acoustics & Placement: Destructive room mode nulls that swallow bass frequencies, out-of-phase speaker wiring, or mechanical vibration rattling loose shelf objects.
- Transducer & Component Failure: Blown voice coils, torn speaker cone surrounds, dried out electrolytic capacitors, or fried amplifier output stages.
How to use this diagnostic
- Choose the primary symptom you are experiencing from the grid above.
- If prompted, trigger the interactive audio check with moderate listening volume.
- Follow the sequence of questions based honestly on what you perceive.
- Review your final verdict, action checklist, and linked specialized test tools.
Frequently asked questions
How does the diagnostic wizard test my audio?
The wizard generates calibrated test tones, frequency sweeps, and phase-correlated signals directly in your browser. By answering simple questions about what you hear, the decision tree isolates software settings, cable faults, room acoustics, or physical driver damage.
Can this wizard fix my hardware automatically?
The wizard diagnoses the root cause and provides a concrete checklist to resolve it (e.g. swapping inverted speaker wires, adjusting OS balance, cleaning 3.5mm jacks, or repositioning subwoofers). Hardware faults like blown voice coils will be identified so you know what component requires repair or replacement.
Is any audio recorded or sent to a server?
No. All test signal generation and diagnostic logic runs 100% locally in your browser using the HTML5 Web Audio API. Zero telemetry or audio data leaves your device.
My amp is on but I get no sound from my speakers — where do I start?
Work from source to speaker: confirm the right output device and that nothing is muted, swap cables and inputs, test each speaker individually, then run a channel sweep at modest volume. The wizard turns your answers into a ranked verdict, so note exactly which steps stay silent versus distorted.
