Choose the test that matches the symptom
Start with the smallest check that can confirm the issue. Channel and stereo tests answer routing questions, balance and phase tests reveal imaging problems, bass and frequency tests help isolate rattles or dropouts, and the microphone test verifies input permission and local recording playback.
Headphone Tests
Left Right Test
Check whether left and right headphone channels are routed correctly.
Stereo Test
Listen to a tone moving across the stereo field.
