S3219D, speakers stopped working

I was surprised today when I tried to play a video on my PC and there was no sound. I think the speakers on my Dell S3219D stopped working. 

My output device is set to Dell S3219D High Definition Audio Device and when I test it, I hear nothing or occasionally I might hear a soft tick. I have tried Windows troubleshooting, Windows is up to date, I have tried SupportAssist. I am running Windows 10 on a Dell Optiplex 3050. 

Today I installed Critical updates: DBUtil Removal Utility and Dell OptiPlex 3050 System Bios. I also installed a recommended update: Intel Management Engine Components Installer. I installed Feature update to Windows 10, version 22H2 today as well, but neither helped.
