Sound is not working with anything no even head phones - bought this about 30 days ago

[GramsTennessee]

Sound was working fine last night and today nothing - It is showing that I have speakers and headphones attached but I don't. It is saying that the HDMI cable is not hooked up but its an all in one and everything that was plugged in the first day is still plugged in - pretty much the power cord and the two USB things for the wireless keyboard and the wireless mouse - Headphones don't work either - Any help would be awesome!

Good Day. A warm welcome to the HP community. I reviewed the case regarding issues with the computer.

I will be delighted to assist you here. 

Use the Windows Sound troubleshooter

Open the Sound troubleshooter.

1. In Windows, search for and open Control Panel.

2. Click Troubleshooting.

3. Under Hardware and Sound, click Troubleshoot audio playback.

   NOTE: 

   Administrator permission is required to run this program. If prompted, type the administrator password or provide confirmation.

   

4. The Sound troubleshooter opens. Click Next. The troubleshooter begins checking the audio service status.

   

5. Select the device you want to troubleshoot, and then click Next.

6. Follow the on-screen instructions and make any changes suggested by the troubleshooter. When done, close the troubleshooter.

Keep me posted. 🙂
