If you are getting the 'fail sound', it is likely there is sound enhancement still running on the HP computer,
It just looks different to what they are used to. This is likely as HP include sound enhancement on nearly all computers, and have changed what it looks like many times in the last few years, so it can be hard to find.
Here are three different HP Windows 10 sound enhancement systems and how to turn them off:
1 'HP Audio'
The important setting here is Optimize speaker for: Music.
2 'HP Beats Audio'
The important settings here are 'Beats Audio' unticked, Music selected, and Graphic Equalizer set to <None>.
3 'Sound Effects'
