I'm developing an application and I am thinking of spending time to add audio feedback when users click on buttons, switches tabs/screens, etc. In my mind it will enhance the user experience as it provides clearer feedback and it helps the user understand what is happening. It can provide a pleasant soundscape with your application - provided they are subtle, gentle sound cues that doesn't get annoying (perhaps provide many variations of the same sound).
I've noticed that there is in general a lack of audio feedback when interacting with application UIs. On the other hand, in video games there is usually both visual and audio feedback when clicking on buttons, etc.
So I'm curious as of why there is this lack of audio feedback in applications. Why are applications so silent? And I also notice a lack of interest in audio in general - hardly anyone talks about this (I had trouble finding anything online that discusses this). Is it simply that audio get forgotten and is deemed unimportant? Has it been to technically cumbersome to implement? If we are to provide excellent user-experiences why are we not using audio feedback more in applications?
EDIT: My question is similar to Why is sound sparingly used on websites? and although some answers there are relevant, I'm asking about sound in applications specifically, and there are slightly different concerns.
