This procedure covers an identified audio-device driver change followed by missing output, failed headphone switching or a broken mute indicator. Confirm the actual audio device and whether the failure began with its driver. A disconnected device or an application’s wrong output selection needs a different correction.

  1. Save work and obtain a supported audio-driver package for the computer’s exact model before removal. In Device Manager, record the affected device, provider and driver version.
  2. If the failure followed a driver update and Properties > Driver > Roll Back Driver is available, use that option, restart, and test. Stop when the original audio function returns.
  3. Otherwise uninstall only the identified audio device, initially retaining its existing driver package. Restart so Windows can enumerate it again. Install the prepared OEM package if required.
  4. One historical IDT case selected Microsoft High Definition Audio Device through Update driver > Browse my computer > Let me pick. Use this only when Windows lists it as compatible; do not force a generic driver onto unsupported hardware.

Test the affected output, headphone switching and the relevant mute control. Confirm the intended device and driver version remain installed after restart. If the change worsens audio, reinstall the saved previous OEM package. Stop repeated driver removal when the result does not change.
