If you are watching a video or playing a song and there is no sound it’s infuriating. In this guide, I will tell you How to Fix Realtek Digital Output No Sound Issue. I also had a similar issue and spent a lot of time learning how to fix it. It took me 10 hours to find the right solution. So I decided to write about it. I hope it saves your time.
The methods listed below will help you resolve the problem.
There are 6 options for resolving the issue. You can try each one at a time until the problem is resolved.
Method 1 – Make Speakers/Headphones the default device
Realtek Digital Output Devices are high-definition digital audio devices such as a TV, a home theatre system, etc. Typically, these devices are connected to the computer via a digital cable rather than an analog one.
Regular speakers/headphones, on the other hand, must be connected to the computer via analog wires. If you designate the Realtek Digital Output as the default output device in this scenario, the sound will not work properly.
To resolve the issue, change the default output device to Speakers / Headphones.
To do so, follow these steps:
1) To open the Run box, press Win+R (the Windows logo key and the R key at the same time) on your keyboard.
2) In the Run box, type ‘control panel’ and press OK to launch the Control Panel window.
3) Go to View by Category and select Hardware and Sound.
4) Select Sound.
5) Go to the Playback tab. Then, choose the ‘Speakers / Headphones’ device and click Set default to make it the default device.
6) To save the changes, click OK.
