The Choose Passage dialog box opens.

) the passage that corresponds to the audio file.
The association happens immediately and the dialog box closes.
Click Auto Match.
The File Name Template control appears.
If your file name convention does not match the default template, click and edit the template to match it.
Here are some things you can do to make the template match your audio file names:
Select and delete an entire code.
Click between codes and then delete or add a dash.
Click 
and click the code you want to add from the list in the Template Codes dialog box. That code is added to the end of the exiting template.
Click

As an audio file is associated with a passage, you see its button change from to 
.
After the auto match process is finished, you may see files that were not associated with passages. In this case, you may need to use an iterative approach. Examples:
If your file names are inconsistent, here are things you can do:
Associate them manually.
Edit the template to match those file names.
Edit the names of those files and then upload them again.
Your project has a project type set to Scripture (
) and you have audio files and passages that are for one verse, instead of a range of verses.
Here is something you can consider to help the best matching of audio files and passages:
You can change the file name template to match the format of the audio files that you uploaded and want to match. For example, if your audio file name was "0010 Marriage" where 0010 is the section number, the template may simply be {SECT} since matching the number at the beginning uniquely connects the passage to a section in a flat layout. This is common with Render exports.
You can click 
(Play) to listen to the audio file.
The Versions dialog box shows all the versions of the audio files that have been associated with the passage.
