Something wrong, but unclear what. Contact Dell tech support and if they can't fix it by phone, have it fixed under warranty or return it.
I have a brand new Dell XPS-13 ultrapoartable with Windows 10 Creators Update. There is a sound delay of 2 seconds. Cuckoo at top of hour sounds two seconds later. Caps Lock sounds 2 seconds after it is pressed. Please help Windows Audio troubleshooter is no help.
