RE: Windows 10 Video and Audio Not Working
Thank you for writing to us!
Since you have updated the drivers kindly private message the service tag, email address and also a screenshot of the device manager.
In the meanwhile kindly check the following:
1- Update BIOS on the system http://dell.to/2gyxPFj ( link to the latest BIOS)
2- Run Diagnostics on the system.
3- Check for windows pending updates.
4- Use external speakers to check if the audio works fine.
