Windows 10: Fail to play test tone on any audio device.

My computer is a windows 10 alienware laptop that has failed to play a test tone with my speakers, tv or bluetooth headphones. I believe my bluetooth headphones were connected when I walked out of range and disconnected which started the issue. I have tried the following things to try and fix it.
Disabling and enabling the audio speakers

• Updating the drivers
• Uninstalling the drivers and restarting so that it automatically puts in the audio driver
• Restarting the Windows Audio Services
  sfc scannow to repair corrupted files
  Change the sample rate of the audio
  Disable audio enhancements
• Enable applications to take exclusive control of the device.
• Disable applications to take exclusive control of the device.
• I checked and no updates have been installed since it was working.
  Install High Definition Audio Device
• Run the troubleshooter
• Set audio speakers as the Default
• Try other speaker options such as BT headphones and a TV through HDMI
• Change local and user group settings

Any help and suggestion would be greatly appreciated.

No audio from speakers; Failed to play test tone.


I have a Dell Latitude E6520 running Windows 10 Pro x64. When I try to watch YouTube I get no audio. Spotify plays and gives no errors but doesn't have sound. When I plug in headphone sound plays but as communications headphones. When I try to play a test sound through Speakers/Headphones I get an error that says "Failed to play test tone." When I try to troubleshoot it can't identify the problem. I have attached the report from troubleshooting.
Thanks in advance for helping.
