No Sound/Audio in Dell Laptop

Hello Guys, I have a relatively new laptop (7 months old) I did a windows update today and after that laptop audio says no audio hardware found. There is X symbol on audio in notification tray. I did the usual uninstall reinstall etc no use. I go to device manager and I don't see the sound tab to expand. Under system devices, there is a error for Intel Audio system Bus. when I right click sound and click playback, I don't see any devices listed either. What would be my next troubleshooting step, please help Thanks

 

No Sound- Says No Audio Output Installed

Hello Cole,

One possible reason why your audio suddenly stopped working is due to an incompatible driver. To better assist you and provide you with the appropriate troubleshooting steps, kindly answer the questions below:

• Were there any hardware/software changes on your computer prior to this happening?
• Are you using any external speakers, headphones, Bluetooth devices for your audio?
• What is the current version and build of your Windows 10? To check, type
  winver on Cortana's search field and press Enter.
