Hi Bernaleigh Visagie,
Welcome to Microsoft Q&A forum. I'm happy to help.

Have you tried taking a Reboot (not Shutdown) your computer?

Your audio services might have problem during sleep session, this can be fixed easily with just a simple reboot.

If you have any updates, please feel free to let me know.

Please clarify the following:

Are you trying to play audio via internal speakers, external speakers, or headphones?

If it is an external speaker or headphones, does it have a standard audio connector (Jack connector) or USB connector, or is it connected via Bluetooth?

Is there an X in the speaker icon next to the clock?

Also, share a screenshot of your system information.

• Press "Windows + R", type msinfo32 and press Enter.

Maximize the window and use the shortcut "Windows + Shift + S" to use the screenshot tool.

I await your reply.

Try these steps in order on the Windows laptop:

1. Run the audio troubleshooter again
   Use the built-in troubleshooter, which can automatically detect and fix many sound issues:
   • Open the Get Help app and run the audio troubleshooter from there. It will run diagnostics and attempt repairs.
   • If using Windows 10, also try: Start > Settings > Update & Security > Troubleshoot > Playing audio > Run the troubleshooter.
2. Check the output device and volume
   After sleep, Windows can switch devices.
   • Select the Speakers icon on the taskbar.
   • Select the arrow next to the volume slider and make sure the correct speakers/headphones are selected as the output device.
   • Confirm system volume and app volume are not muted and are turned up.
3. Turn off audio enhancements (Windows 10)
   Enhancements can sometimes break audio:
   • In the search box, type control panel and open it.
   • Go to Hardware and Sound > Sound.
   • On the Playback tab, right‑click the default device > Properties.
   • On Enhancements, select Disable all enhancements or Disable all sound effects, then OK and test audio.
   • Repeat for other default devices if needed.
4. Check for Windows updates and restart
   • Go to Start > Settings > Update & Security > Windows Update > Check for updates. Install any available updates.
   • After installing, restart the PC.
   • If the Power menu shows Update and restart or Update and shut down, choose one of those so audio‑related updates are applied.
5. Update, reinstall, or roll back the audio driver
   Sleep/wake issues often come from drivers.
   • Open Device Manager (search for it from the taskbar).
   • Expand Sound, video and game controllers.
   • Right‑click the sound card or audio device (speakers/headphones):
     • Choose Update driver > Search automatically for updated driver software and follow prompts. If no newer driver is found, check the device manufacturer’s support site for the latest audio driver and install it.
   • If audio stopped working right after a Windows update, try a driver rollback:
     • Right‑click the audio device > Properties > Driver tab > Roll Back Driver, then follow the instructions.
   • If updating/rollback does not help, try uninstalling the driver:
     • Right‑click the audio device > Uninstall device and (if shown) check Delete the driver software for this device > Uninstall.
     • Restart the PC so Windows reinstalls the audio driver automatically.
   • If still no sound, in Device Manager right‑click the audio device > Update driver > Browse my computer for drivers > Let me pick from a list of device drivers on my computer and select the generic audio driver that comes with Windows.
6. If audio issues started only after a recent update
   If sound worked before a Windows Update and stopped afterward, and rolling back the driver did not help, restore the PC from a system restore point created before the update. For details, see "Restore from a system restore point" in Recovery options in Windows.

If none of these steps restore sound, the issue may be hardware‑related (for example, internal speakers or audio circuitry), and the device manufacturer’s support should be contacted.
