Fix: Windows 10 computers lose sound after sleep mode

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 wake 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 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 to fix lack of sound on Windows 10 after sleep mode

Run the Sound troubleshooter

Manually update the audio driver

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.

See if this works.
