The audio icons do not appear if you search for a word using Basic Search for this resource. They do, however, appear if you use the sliding cursor to get the approximate location of the word. Even this procedure fails on occasions. Also, there are words without audio icons, e.g. Zebadiah.
I have reported this in the Android app forum because my reader is a Fire HD, however, this appears to be the case for iOS as well, as my iPhone 5S exhibits like behavior.
