Windows 10: No audio device is installed on laptop

Good afternoon,When my daughter switched her HP laptop on this morning and tried to play music via an app e.g., YouTube there was no audio output.When checking the taskbar, the speaker has an "X" applied to it with the message "No audio device is installed".I tried the following:Function key in case it was pressed off, but made no difference.Checked the settings, but wouldn't allow me to move the volume slider.Uninstalled an update that was applied yesterday, and restarted but no change. The laptop's audio was working fine yesterday.Thanks in advance.

no audio output device installed

I've tried every step that was suggested, still getting no audio output device installed.

 

HDMI audio driver for ASUS X551M laptop?

This is from Intel regarding hdmi:

• Install the latest Intel® Graphics Driver, this also installs the latest audio codecs for HDMI.
• After driver installation, connect to the HDMI TV or digital display, using a HDMI cable.
• Select HDMI audio as your default playback device. Click Start>Control Panel>Hardware and Sound.
• Click Sound. The Playback tab lists the audio playback devices for your computer.
• Right-click on the device for HDMI audio, and select Set as Default Device.

 

Numerous audio devices - why?

Looks like you have audio drivers installed for your AMD card. If you don't use it, you should be able to just uninstall that aspect of AMD drivers. I don't use the Audio through my Nvidia card, so I just don't install that driver.

Or, just ignore them as you suggest.
