Description
Chrome and Firefox browsers display "plugin unsupported" when .wav audio files are embedded by using the Visual Text Box Editor (VTBE).
Steps to Replicate
Log in to Blackboard Learn
Go to a Course
Control Panel > Files (or content management)
Upload a .wav file to the course files
Go to Tests, Surveys, and Pools > Tests > Build a test '.wav audio'
Create exam question #1 and in VTBE > Insert/Embed Media > upload a .wav file from your local computer
View the question as a professor or student
Observed Behavior:
The following error occurs in Chrome and Firefox:
Plugin unsupported.
Expected Behavior:
The embedded .wav audio file plays without error.
Cause
The VTBE creates the embed via the following HTML and sees the .wav as a "Windows Media" file (and you cannot change this).

Resolution / Workaround
Attach the .wav audio file, instead of embedding it.
