Dell Sigmatel delayed sounds in Vista
I’ve now got a couple of machines that run Windows Vista and I noticed with the first machine that Vista’s event sounds were somewhat delayed from the event occuring, e.g. the sound you experience when UAC prompt pops up wouldn’t be in sync with the actual popup of the dialog box, but a second or so later.
Anyway, I googled it and the solution is to disable enhancements for the playback device in use. Screenshot below!
