I have an older Dell laptop 3501 that I updated to Windows 11 a few months ago. Lately when the computer goes idle the screensaver no longer works and the audio stops working, and also if I close the lid.  I have to restart the computer each time to get the audio back.  I have run the audio troubleshooter several times and the problem remains.  As soon as the computer is idle I lose the audio.  My windows is up to date, and I do have a screensaver chosen, it is not locked.  I did not have this problem until recently, the windows 11 update was working fine until then.  I run Windows Defender for  virus control.

Is this a glitch in an update that caused this, or do I just blame it on my computer being older? Whatever, it is sure a pain to deal with. Any suggestions, thanks..
