For email, Facebook, etc alerts. As long as I'm on the default Windows sound theme, it plays an audio alert whenever I receive a desktop email (the banner popping up in the lower right of the desktop). I decided to create my only sound theme with custom sounds I've collected online over the years. I set them as I have in every other version of Windows I've used (from the 9x days). I tested each sound by clicking on the speaker icon and they all played. So I saved the theme and thought that was that.
Now, I only get silent toaster popups, with none of the audio I've set. I've been over the notification settings for each app with a fine tooth comb. All are enabled. If I switch back to the Windows default theme, the sound alerts from that play.
I simply cannot figure this out.
Thank you for any assistance.
