If you like to enjoy in multimedia content then you probably have 5.1 surround speaker system. These speakers are perfect for all fans of multimedia and it’s a big problem when 5.1 channel sound isn’t working on Windows 10, so let’s see if we can fix this.
What to do if 5.1 Channel Surround Sound Isn’t Working in Windows 10
Users report that they can only get 2.1 audio, although 5.1 audio worked fine with previous versions of Windows. In addition, users are getting Failed to play test tone error when trying to test their audio device. So what can we do to fix this issue?
Solution 1 – Change the sound bit rate and frequency
This applies if you’re using Realtek Sound. To fix this, you need to open Realtek Sound manager and set the sound bitrate to 24bits and frequency to 96000Hz for 5.1 audio to work properly. If this option doesn’t work, you might want to try changing the bitrate and frequency until you find the one that works for your computer.
Solution 2 – Update your audio driver
If you’re using Realtek audio, you might want to download the latest drivers, or any version of drivers higher than 18.104.22.16887. Some users report that this was helpful to them. If you’re not using Realtek audio, it won’t hurt that you try updating your audio driver as well.
All your drivers need to be updated, but doing it manually is very annoying, so we recommend you to download this driver updater tool (100% safe and tested by us) to do it automatically.
We also have to mention that Microsoft is aware of this issue and it’s working hard to fix it, and according to Microsoft they already have a working solution available for their Insiders program. After the solution has been tested by Insiders and confirmed that it works it should be available for all users.
If none of these solutions were helpful to you, make sure that you keep your Windows 10 up to date and wait for the official solution from Microsoft.
