Seems like on my note 3 I was able to set the timer audio directly on the app page. Seems like a very basic and obvious UI option, just toss it in a hamburger menu, gear or volume icon. Instead it's buried in the settings, and I seem to have lost my timer audio by setting system sounds to vibrate. I cannot figure out how to set the timer audio specifically. I know there are hundreds of timer apps I can use instead, but this seems such an obvious UI feature, not sure why Samsung thought it would be smart to ditch it.
