Put on the headphones, begin at low volume, and test each side before a sweep.
Understand the result
PASS describes a received signal or your recorded observation. WARNING calls for another check. USER REVIEW REQUIRED means a measurement alone cannot decide. An unavailable API or denied permission does not establish hardware failure.
What this cannot tell you
This is a listening check, not a hearing test or calibrated frequency-response measurement.
If something seems wrong
Try a wired connection, reseat the plug, check balance, and compare another audio source.
