Sound issues aren’t exactly an alien concept on the Windows platform, something that applies to the latest Windows 10 operating system as well. And a common problem experienced on Windows 10 PCs is the device going dumb each time it wakes up from sleep.

Curiously, the sound issue is non-existent when the device is back from hibernation, or after a restart. Somehow it is only when the device is out of the sleep cycle that it tends to lose it audio abilities.

All of this makes it not too big of an issue, but one that can drive you nuts nonetheless; more so if you are a music buff and can’t resume your listening post-sleep mode.

However, a few simple tweaks is all that is needed to set things right.

How can I fix no sound on Windows 10 after sleep mode?

  1. Update the audio driver
  2. Run the Sound troubleshooter
  3. Change system memory value

1. Update audio adapter

Outdated driver software can also be the culprit here. Here is what you need to do to have the latest driver on your device.

  • Type Device Manager in the taskbar search box and select Device Manager from the search results.
  • In the Device Manager window, select Audio inputs and outputs > Headphone and/or Speakers depending on whether or not you are not getting sound on both. The process of updating driver is same for both. Here it is:
  • Select Headphone and/or Speakers > right-click and select Properties.
  • In the dialog box that appears, select Driver > Update Driver.
  • In the ensuing window, select Search automatically for updated driver software and follow on-screen instructions.

If need be, search for the drivers manually if an automatic search fails to resolve the issue.

You might also be required to visit the manufacturer’s website and see if there is the latest version of the driver available.

This is particularly applicable if you have recently upgraded to Windows 10 while the audio drivers installed on your device aren’t compatible with the latest Windows version.

Once you have access to the latest drivers which can be either on the hard drive of your PC or any other location, here is how you update the same.

If you’re looking for a way to simplify the process, then a third-party driver updater like DriverFix should do the trick for you.

All you need to do is run it and it will instantly start scanning your PC for outdated, broken, or even missing drivers.
