Audiodg.exe is causing speakers’ sound malfunctioning

While listening to anything on my laptop or playing games, the sound from the speakers’ just stops randomly

To get it back to work, I either:
- Kill audiodg.exe process
- Disable and re-enable speakers from the list of playback devices
- Restart Computer

What I have already done trying to resolve the problem:
- Uninstall/Re-install Sound Drivers
- Check for Updates for sound drivers
- Perform a Full System Scan with both Avast Internet Security and MalwareBytes PRO
- Replace my audiodg.exe file from another PC’s
- Full Scan with DllSuite for dll problems
- sfc /scannow

Additional informations:
- this never happens while using plugged-in headphones, meaning the sound never stops randomly
- The higher volume the quicker the sound stops.
