When a computer function works in another app, user account or port, keep the repair inside the failing context. For Windows audio device and driver, first play the test tone, inspect the volume mixer and test a known headset.
What this covers
- Windows audio device and driver with this exact failure state
- Diagnosis across speaker/headset hardware versus output selection, app mixer and driver
What it does not cover
Try in this order
0 of 4 completedCapture the exact failure state
ReversibleName the failing app, user account, port or peripheral and one that still works. Expected behavior: route audio to the selected endpoint with the correct sample format.
Isolate the component boundary
ReversiblePlay the test tone, inspect the volume mixer and test a known headset. Swap only the app, account, cable, port or user profile while keeping the computer unchanged. Boundary to separate: speaker/headset hardware versus output selection, app mixer and driver.
Correct only the proven cause
ReversibleSelect the right endpoint, restart audio services or install the OEM driver. Repair the isolated app, user profile, driver binding or physical path.
Verify and stop safely
ReversibleRetest both contexts after sign-in and one cold restart. Stop for loud popping, heat, liquid or a damaged jack.
