[HP Compaq dc5800 Small Form Factor, Analog Devices AD1884, Black Headphone Out, Front] No sound at all

[Will]

I made some modest security configurations yesterday, and today, less than 24 hours later, I have no sound. I've conducted the relevant checks, but I can't pinpoint the fault. I ruled out hardware issues since I started the computer with Windows 11 and had no problems playing sounds.
