@ joelrosado , Success for me . I went hunting with my ears to identify the sound in Windows sounds .
Some stats :
My OS is Windows 7 HP SP1.
The version of DVDFab I’m using is the last version 8 Qt ( 18.104.22.168) .
The audio file DVDFab uses for it’s wait is located here on my OS:
This is a Windows Default sound .
I created a new folder in C:\Windows\Media\ named “Defaultold”.
I then used Properties/Security/Advanced Permissions
Auditing Owner Effective Permissions
& took ownership of all these as administrators of the Windows Exclamation.wav. This is necessary to move it to the Defaultold folder.
I then copied & pasted in a .wav I wanted to make the "Waiting " sound in DVDFab.
I renamed it: Windows Exclamation.wav
The last thing I need to do was enable it as a Windows Sound.
I usually keep Windows Sounds disabled . So I chose & applied Windows Default in Windows Sounds at first then tested. I had the .wav file I had substituted play in DVDFab “Waiting”.
I then went back to my usual setting in Windows Sounds :No Sounds (modified).
I went down the list to: Exclamation selected it & Applied. This way it works with most of the other Windows Sounds disabled.
If you don’t know how to access Windows Sounds : Right click on the Speaker icon in the systray . Select “Sounds” .
I hope this will work for you on V 9
