Select the Volkano speaker as the active output device, then set its Bluetooth format to 2 channels, 16 bit, 48000 Hz (DVD Quality) if the playback meter moves but the speaker remains silent.^1^
1. Verify audio is routed to the Volkano speaker
Windows 11
- Select the Sound icon on the taskbar.
- Open the output-device selector beside the volume slider.
- Select the Volkano speaker—not the Surface speakers or a similarly named hands-free device.
- Go to Settings → System → Sound → Output and select the Volkano speaker again.
- Play audio and raise both the Windows volume and the speaker’s physical volume.
Windows 10
- Select the Sound icon on the taskbar.
- Choose the Volkano speaker under Select playback device.
- Confirm it under Settings → System → Sound → Choose your output device.
The expected result is that the output meter moves specifically beneath the Volkano device and sound comes from it. Surface audio guidance confirms that Bluetooth accessories must be selected under the Sound Output setting and may have an independent volume control.^2^
2. Set the documented Bluetooth audio format
The speaker must be connected while changing this setting.
Windows 11
- Open Settings → Bluetooth & devices → Devices.
- Select the Volkano speaker.
- Select Advanced sound properties.
- Under Output settings → Format, choose 2 channels, 16 bit, 48000 Hz (DVD Quality).
- Test playback again.
Windows 10
- Right-click the taskbar Sound icon and select Sounds.
- Open Playback.
- Select the Volkano device and choose Properties.
- Open Advanced.
- Set Default Format to 2 channel, 16 bit, 48000 Hz (DVD Quality).
- Select Apply → OK, then test playback.^1^
If it is still silent
Work through these in order, testing after each change:
- Remove and pair again
- Windows 11: Settings → Bluetooth & devices → Devices → Volkano → … → Remove device, then Add device.
- Windows 10: Settings → Devices → Bluetooth & other devices → Volkano → Remove device, then Add Bluetooth or other device.
- Reset Bluetooth
- Turn Bluetooth off, wait 10 seconds, turn it on, and reconnect the speaker.
- Update the Bluetooth adapter
- Open Device Manager → Bluetooth.
- Right-click the Bluetooth adapter—not merely the speaker—and select Update driver → Search automatically for drivers.
- Restart if prompted, pair the speaker, and test again.^1^
- Update the Surface
- Open the Surface app → Help & support.
- Check the update status and select Check for updates when offered.
- Install available Windows, Surface driver, and firmware updates, then restart.^2^
- Run Bluetooth diagnostics
- Open the Get Help app and run the automated Bluetooth troubleshooter.
If the Volkano works with another phone or computer but remains silent on the Surface after these steps, provide the Windows version, Surface model, exact Volkano model, and whether the speaker appears as more than one output device. If it fails on every device, contact Volkano support; Microsoft’s Surface guidance directs unresolved accessory-specific issues to the accessory manufacturer.^2^
