Hi UK. I'm Greg, an installation specialist and 9 year Windows MVP, here to help you.

For sound problems first try this checklist: https://support.microsoft.com/en-in/help/402699...

Then if necessary work through the following steps:

1. Update the sound driver from the PC maker's Support Downloads webpage for your exact model, if it is newer than the one presently installed in Device Manager reached by right clicking the Start button. While there compare to make sure you also have the latest BIOS, Chipset, Display, Network and all other drivers.
2. Right click the volume icon in System Tray at right end of task bar, to Troubleshoot Problems.
3. Run the Playing Sound troubleshooter at Start button > Settings>Update & Security>Troubleshoot.
4. Try rolling back the sound driver in Device Manager reached by right clicking the Start button. Choose Sound controller device, then Driver tab, then Roll back if available.

While there make sure you also have the latest Chipset, Display, Network, USB and all other drivers, comparing with the version presently installed in Device Manager.

5. If no newer driver then uninstall the one presently installed in Device Manager, reached by right clicking the Start Button. Restart PC to reinstall.
6. Try other and older drivers for your model Sound controller, too. For example, try the next oldest driver in the model's online Support Downloads list. To try all previous drivers installed on your system, in Device Manager choose Sound controller's Driver tab, then Update Driver, then Browse, then Let Me Pick.
7. If this was caused by Windows Updates then you can check which were installed at Settings>Update & Security>Windows Update under Installed Updates, then uninstall them from the link there, and hide with the Hide Updates tool downloaded from here: http://download.microsoft.com/download/f/2/2/f2...
8. You can also use System Restore to get before the problem began, then check for Updates with the Hide Update tool and hide them: http://home.bt.com/tech-gadgets/computing/how-t...
9. Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files. Then continue with the other steps to go over your install most thoroughly.

10. If nothing else helps then run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This solves many problems and will also bring it up to the latest version which you need anyway and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m...

But remember that Factory or Upgrade installs are inferior installs which most enthusiasts won't even run because they'd expect endless issues. Consider doing the Clean Install in this link which compiles the best possible install that will stay that way as long as you stick with the tools and methods given: http://answers.microsoft.com/en-us/windows/wiki...

There is also an automated Refresh that reinstalls WIndows while shedding corrupting factory bloatware, saves your files, but doesn't clear the drive to get it cleanest: https://www.howtogeek.com/265054/how-to-easily-...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
