Compare audio from two apps.

  2. Check that app in the Windows volume mixer while it is playing. Avoid changing every device at once.

Continue if the earlier steps did not help. Read each procedure’s precautions first.

04

Check drivers and audio support

  • Estimated time: 10 min
  • Intermediate
  • Low risk
  • Administrator required
  • Restart required

Audio capabilities vary by accessory.

  1. Run Bluetooth diagnostics in Get Help. If an update is indicated, use the adapter’s official driver for your Windows version and save your work before restarting.

  2. If the device connects but never appears as an output, check its supported audio profiles with the manufacturer. Do not force formats Windows does not offer.

Still not working?

If other outputs fail too, continue with No sound in Windows. If only this accessory fails, give its manufacturer the accessory model, Bluetooth adapter and whether it appears in Sound.
