the selected output produces no audible sound
This symptom concerns the audio path. Start with a neutral DeviceOK test where available so the next step is based on evidence rather than a generic reset sequence.
Do not jump to the most invasive fix
Avoid destructive resets, unofficial driver packages, firmware flashing, or replacing hardware before the simpler detection, permission, connection and configuration checks are exhausted.
Retest the same condition
After every meaningful change, repeat the same test under the same conditions and compare the result.
Rule out the simple causes
- 1
Run DeviceOK left/right speaker test at a safe volume.
- 2
Confirm the intended output device is selected in the operating system.
- 3
Check system and app volume/mute separately.
Work through the problem in order
- 1
If DeviceOK audio works but one app is silent, inspect that app's output device and volume mixer entry.
- 2
If DeviceOK is silent too, check the default playback device, cable/Bluetooth path and OS audio troubleshooter.
- 3
Only move to official driver/device support after output selection and connection are confirmed.
DeviceOK sound output working makes a completely failed speaker/headphone path less likely and points toward the affected app's audio routing.
No audio in DeviceOK and other trusted sources broadens the problem to OS output selection, connection, driver or hardware.
