Manual confirmation remains essential for output tests
How To Use It
- Connect the right output device and raise your system audio.
- Play a short ping, stereo pattern, or pulse train.
- Confirm whether you heard the expected result.
Troubleshooting
- Browsers cannot force system output routing, so verify the operating-system output device first.
- If autoplay is blocked, click a playback button directly to create the audio context.
