How to Fix Audio Playing Through Only One Speaker
You hear one channel but the other appears silent.
Before you begin
Start with reversible settings checks. Keep your device supported and powered safely. Do not force connectors, open sealed batteries or try high-voltage repair steps.
How to troubleshoot the problem
- 01
Check channel balance settings
Set left/right output balance to center, and inspect any mono-audio accessibility setting.
- 02
Swap source content
Use a known stereo sample instead of relying on a single media recording.
- 03
Check wiring or pairing
Reconnect cables securely or re-pair wireless headphones without forcing connectors.
- 04
Try another output
Compare built-in speakers and headphones on the same source.
- 05
Test a second device
If the problem follows the headphones or speaker across devices, suspect the peripheral.
Check the result.
Use the balance test, confirming sound separately with your ears; the browser cannot automatically verify speaker output.

If the same problem occurs in multiple compatible applications or devices after safe checks, follow the manufacturer's exact support instructions or ask a qualified repair professional. A browser test cannot prove every hardware component is healthy.
