How to use this test
Lower system volume, choose a channel or tone, listen briefly, then stop before changing equipment.

If the cue is clear in the expected channel, the current audio output functions for this test.
Troubleshooting
Check output selection, balance, mute controls, cable/Bluetooth state, and system volume.
Browser limitation
