Realtek 1903 Update Issue

HP Recommended
HP Pavilion Laptop 14-bf0xx
Microsoft Windows 10 (64-bit)

After updating Win10 to build 1903, plugged in head phone and speaker work at the same time. It is meaningless if I intend to not bother other people around by using a head phone but there is still sound coming from speaker.

I tried to reinstall and update the drivers but it did nothing. 

Please help me!

Hi! @DongPham,


Please share the product number of the PC to assist you better.


Try few steps recommended below.


Right click on the speaker icon and click on Playback devices. Left click on the device you want to listen to and click 'Set Default'.


1. Go into Control Panel, then Sound.
2. Look for the Recording tab.
3. Select your microphone/headset as the default device, and press OK.


1. Press Win+X (Windows logo key and X key)  at the same time.

2. Select Control Panel in the pop-up menu. 

3. View by “Category” and click on Hardware & Sound.

4. Click on Sound.

5. Select Headphones and click Set default button at the bottom.

In some cases, there is no headphone option alone but Speakers/Headphone. If that’s your case, select that and click Set default button at the bottom.

6. Click OK button.


Go to Start, enter Sound, and select Sound Control Panel from the list of results.
On the Playback tab, right-click (or press and hold) the Default Device and select Properties.
On the Enhancements tab, select Disable all enhancements checkbox and try to play your audio device.
If that doesn't work, select Cancel and, on the Playback tab, select another default device (if you have one), select the Disable all enhancements check box, and try to play audio again. Do this for each default device.


Lastly, uninstall the audio drivers from the device manager and install the latest audio driver using the HP support assistant.

Let me know if this works!

Have a great day! 🙂
