Check Your Hardware

We often get confused between hardware and software errors. Both are completely different things. Software errors can be fixed by reinstalling the software or updating it. However, hardware errors need to be checked and solved by a technician. There are a few best ways to test your sound hardware.

Test your speakers first. If you use headphones, switch them to another device, i.e., a smartphone or PC. It might ensure that your headphones are making the sound or your computer is at fault. If you use the built-in speakers, connect an external speaker or headphones to see if that works.

If you are using two sound sources with one computer, then this muffled sound error may occur as one source will use more voltage and sound signals than the other; as a result, you will get a muffled sound. So, you need to disconnect one of them to confirm the reason. 

Audio Troubleshooting 

Audio troubleshooting Wizard is an inbuilt feature of Windows 10 that can help you diagnose and fix sound problems. This feature can help you fix common sound issues like no audio, distorted sound, muffled sound, etc. 

  • To launch this wizard, type “Troubleshoot audio playback” in the search box and click on the result.

Replace Sound Card

Sound cards are used to enhance the sound quality of your system. If you use an integrated sound card, it’s time to replace it with a new one. Integrated cards often create sound quality issues as they are not as good as dedicated cards. These cards are built only for the best sound delivery. 

You need to open the CPU cabinet and remove the existing card to replace the sound card. After that, insert the new card in its place and then connect all the cables properly. Once done, boot your system and check the sound.


Several things could be causing the muffled sound on your Windows 10 computer, but luckily, there are also a few easy ways to fix it. Here, we have discussed some of the best and quickest methods to resolve the muffled sound in Windows 10 errors in a few minutes. I hope this blog solved your issue.
