You have found this guide because you are experiencing no sound after sleep mode on your Windows 10 PC. Let us show you how to resolve it.

Sound issues aren’t exactly an alien concept on the Windows platform, which also applies to the Windows 10 operating system. 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 returns from hibernation or after a restart. Somehow it is only when the device is out of the sleep cycle that it tends to lose its 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.

Why is there no sound after Sleep Mode?

From what we gather from users who have passed through this problem, a few things may trigger this issue. At the top of these are the following:

  • Outdated drivers – In most cases, this may be the case if the audio driver is outdated.
  • Hardware problems – In some instances, this may be a sign of issues with your computer speakers.
  • Problems with settingsWindows sound enhancement settings, for example, may trigger this problem. You should ensure that you have the best settings for all audio devices.

Here are some practical solutions, and they will also come in handy if the sound stops working after sleep mode, your HDMI audio stops working after sleep, or with brands like Dell, LG, HP, etc.

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

Before you try any of these solutions:
