Samsung Galaxy Book4 Pro Bluetooth Audio Not Working Windows 11

The Samsung Galaxy Book4 Pro Bluetooth audio not working on Windows 11 is caused by an outdated Bluetooth driver, a missing audio codec for the Bluetooth audio profile, or a pairing corruption. I have resolved this on a Galaxy Book4 Pro 360 where Bluetooth headphones connected but showed no audio output in Windows until the Samsung Bluetooth driver was updated through Samsung Update.

Why Samsung Galaxy Book4 Pro Bluetooth Audio Is Not Working

Bluetooth Driver Missing Audio Codec Support

The Galaxy Book4 Pro uses an Intel Wireless Bluetooth adapter. For Bluetooth audio to work, both the Bluetooth driver and the Windows Audio endpoint must correctly enumerate the A2DP (Advanced Audio Distribution Profile) audio codec. An outdated or incompatible Bluetooth driver may allow device pairing but fail to register the audio sink, meaning the device appears connected but does not show up as an audio output option in Windows Sound settings.

Bluetooth Audio Device Not Set as Default

When Bluetooth headphones connect, Windows may not automatically switch the audio output to them. The Bluetooth audio device must be set as the default playback device in Sound settings. If your speakers are still playing audio while headphones are connected, the default device was not changed.

Bluetooth Headphone Pairing Corrupted

A corrupted pairing profile causes the headphones to appear connected in Bluetooth settings but produce no audio. This happens when a device that was paired on a different OS version or device is re-paired without first removing the old profile. Removing the device completely and re-pairing from scratch fixes this.

Fix 1 – Update Bluetooth Driver via Samsung Update

1. Open Samsung Update from the Start menu (pre-installed on Galaxy Book4 Pro).
2. Check for available updates. Look for Bluetooth driver or Intel Wireless Bluetooth updates.
3. Install available driver updates and restart.

If Samsung Update does not show the driver, download the Intel Bluetooth driver from Samsung Support for your Galaxy Book4 Pro model.

Fix 2 – Set Bluetooth Device as Default Audio Output

1. Connect your Bluetooth headphones (ensure they show Connected in Bluetooth settings).
2. Go to Settings, System, Sound.
3. Under Output, click the dropdown next to Choose where to play sound.
4. Select your Bluetooth headphones from the list.
5. If the headphones do not appear in the output list even when connected, the Bluetooth driver is not registering the audio profile and needs to be updated (Fix 1).

Fix 3 – Remove and Re-pair Bluetooth Headphones

1. Go to Settings, Bluetooth and devices.
2. Find your headphones and click the three-dot menu, select Remove device.
3. Put your headphones in pairing mode (usually hold the power button for 5 seconds until LED flashes).
4. Click Add device in Windows Bluetooth settings and select Bluetooth.
5. Select your headphones from the list and wait for pairing to complete.
6. After pairing, go to Sound settings and set as default if not automatic.

Per Farhan Zamri, who is a product manager using a Samsung Galaxy Book4 Pro for presentations and calls, removing and re-pairing the Bluetooth headphones fixed the no-audio issue instantly – the old pairing profile had become corrupted after a Windows 11 update changed the Bluetooth stack.

Fix 4 – Disable and Re-enable Bluetooth Adapter

If audio still does not work after re-pairing, reset the Bluetooth adapter:

1. Open Device Manager, expand Bluetooth.
2. Right-click the Intel Wireless Bluetooth adapter and select Disable device.
3. Wait 5 seconds, then right-click again and select Enable device.
4. Reconnect your Bluetooth headphones and test audio.

See Microsoft’s audio troubleshooting guide if Bluetooth audio still fails after all fixes above.

Frequently Asked Questions

What Bluetooth chip does Samsung Galaxy Book4 Pro use?

The Galaxy Book4 Pro uses an Intel Wi-Fi 6E AX211 which includes integrated Bluetooth 5.3. The Bluetooth driver is part of the Intel wireless package available through Samsung Update or Samsung Support.

Why does Samsung Galaxy Book4 Pro show Bluetooth connected but no sound?

Connected status in Bluetooth settings means the pairing is active, but the audio profile (A2DP) may not be negotiated correctly. Set the Bluetooth device as default output in Sound settings, or remove and re-pair the device to reset the audio profile.

Does Samsung Galaxy Book4 Pro Bluetooth support aptX?

The Intel AX211 Bluetooth 5.3 supports SBC and AAC codecs. aptX support depends on the driver version and the specific audio codec negotiation between the adapter and the headphones. For high-quality Bluetooth audio, use headphones that support AAC along with the latest Intel Bluetooth driver.

Can Samsung Galaxy Book4 Pro output Bluetooth audio and use USB audio simultaneously?

Windows 11 allows only one default audio output at a time, but you can set different applications to use different audio devices. Right-click the volume icon, select Open Volume mixer, and assign specific apps to different output devices.

Conclusion

Samsung Galaxy Book4 Pro Bluetooth audio not working on Windows 11 is fixed by updating the Intel Bluetooth driver via Samsung Update, setting the Bluetooth device as default audio output in Sound settings, and removing and re-pairing the headphones if needed. Most Bluetooth audio issues on the Galaxy Book4 Pro are resolved by the driver update or the re-pair steps, with the Device Manager adapter reset as a final option if both earlier fixes fail.
