Hi
If installing the latest drivers does't work...
That sound like an issue that I had with Windows 10.
Do you have a Sound Blaster sound card?
The first thing that I'd try is opening the Sound panel and look at what it's using as your default sound device.
Open Control Panel and click on Sound and then look at the Playback tab.
If it's showing your sound card as the default device, select Configure and test it.
If you hear the default test sound but you still don't get sound from other sources try uninstalling your sound card in Device Manager,
Right click on the Start Button and select Device Manager.
Find the device that's set as default under, Sound, Video and Game Controllers, right click on it and chose select uninstall, if...
