Audio stopped working

Sorry if this is the wrong thread, but I did not see an Audio thread like the one in Window 10 site.

I'm looking for something I can do to debug my audio issue. It was working well until the other day when I got no sound. I bought a new set of speakers and I have the same issue. I tried several of the miniature phone jack ports, including the one on the front of my tower (Micro-Star International, MS-7B51 running Windows 11 Version 21H2). I also have an NVIDIA GeForce GTX 1070 graphics card. The system audio shows both NVIDIA and Realtek as audio devices, so I don't know which one it uses.

Any help would be greatly appreciated. Thanks in advance.

Do you have the speaker in the Notification Area [where the clock is]? If you hover the mouse over it do you get any kind of message? Have you checked in Device Manager for issues with Audio or Sound? I recently saw a problem where none of the audio functions would work on a Notebook and always returned No audio device found, turned out to be a problem requiring motherboard replacement [under warranty].

Da! Thanks. I had checked al the other volumes, except that one. Thanks again.

You're welcome.

The NVIDIA driver would be used over your HDMI cable connected to your video card and monitor. The Realtek driver would be used for your speakers/headphones output on your computer.
