If you are experiencing audio issues on your Dell computer, make sure to install the latest audio drivers for your computer from the Dell website at https://www.dell.com/support/home/en-us?app=drivers

If this does not solve your problem, contact the Dell support or your system administrator. 

We advise to reinstall the soundbar:

• Make sure the computer is up-to-date via Windows Update
• Remove all errors from the Device Manager, esp, in the sound and the USB sections. 
• Since the Windows update could have adjusted some settings and properties in the Device Manager. Check that the USB controllers > USB Root Hub properties are still correct (e.g. the Power Management).
• Remove the soundbar from the Device Manager
• Disconnect the soundbar from the computer
• Restart the computer
• Connect the USB-cable to the USB-port of the computer for power
• Connect the audio cable to the 3.5mm audio port of the computer for sound
  Note: If your computer has a combined audio port, an adapter is needed. You can contact the support team for this adapter.
• Switch the soundbar on with the button on the front
• Turn up the volume on the soundbar as well as on the computer
• Set the soundbar as the default audio device on the computer
• The soundbar is ready to use
