What do I do when Windows has upgraded to 10 !BEFORE! the HP BIOS was upgraded, on an Envy All-in-On

HP Recommended
Envy All-in-One 27-b214
Microsoft Windows 10 (64-bit)

Instructions say to update the HP BIOS before upgrading to Windows 10. That was not done, but I don't know what to do at this point. Should I run the BIOS upgrade now? My only problem is that my sound is not working, "No Audio Output Device is installed".

@j66b If you've got a BIOS update available to download: click here for instructions on getting that updated, if that doesn't help with the audio issues, here's what should help fix it once and for all:

 

Update the Audio drivers: 

here's the link to download and install the above updates: Click here

 

Once done, use the below steps:

 

Step 1: Right-click on the Start button in the taskbar area and then click Device Manager to open the same.

Step 2: In the Device Manager, expand Sound, video and game controllers.

Step 3: You should now see your audio driver name. Most likely you have Realtek High Definition Audio, Right-click on it and then click Uninstall device option.

Step 4: You will now get the following confirmation dialog. Select Delete the driver software for this device checkbox and then Yes button when you see the confirmation dialog to go ahead and uninstall the device driver.

Restart your PC once & it should auto-reinstall a working driver.

 

If the issue with the sound continues, The best way to resolve the issue is by using the HP Guided Troubleshooter:
