I recently had a problem with timing text with sound (narrator). For example, when a user tapped a button a narrator would read text on the page and the words would highlight as the narrator read the words. The problem I ran into was that it performed well on the desk top but the timing was off on some mobile devices. So I set the sync to "stream" and it worked fine. But I ran into another problem; the sound quality went down, sounding muffled.
How can I make the sound quality better when the sync property is set to "Stream"?
you can control streaming sound quality in your publish settings which can override the sound quality settings that you can set by clicking the library sound's properties (right click/properties).
