Here’s what you need to do to enable speaker fill: Instead of getting the full audio spectrum possible through all the channels, the rear speakers will use virtualization to provide a surround-like effect. While this will allow you to use all your speakers when running Windows 10, the overall sound quality will be lowered. One solution that seems particularly effective for users struggling with the 5.1 channels issue is to enable enhancements and Speaker Fill. Please follow each method in order until you find a fix that works for you. While we wait eagerly for Microsoft to release an official fix for this issue, let’s go over some solutions that have enabled users to fix their channel surround problems on Windows 10. Microsoft is once again using planned obsolescence to force consumers into migrating to Sonic and Atmos. With the new sound technologies like Dolby Atmos and Sonic, Microsoft is unlikely to ever release an official patch for the 5.1 surround issue for Windows 10. Pre-recorded surround tracks like the ones found on DVDs and Blu Rays are now working fine under Windows 10. Right now, the issue only affects surround sound encoded in real-time like games or DTS Live. Even if fixes were implemented on builds 10586.1 and build 10586.3, the issue still partially remains. Update: After more than two years, the surround sound is still partially broken in Windows 10. However, Microsoft has still not provided a fix. Microsoft support personnel announced that they are working on the issue. Because the Realtek’s 5.1 sound card is working properly in Windows 7 and 8.x, users are looking towards Microsoft for the solution to this issue.

Usually, the issue is prevalent in systems having Realtek’s 5.1 sound card.
