You are able to have a compact audio player on your page if you are using audio only files in Vidyard. This will create a player that will not create unnecessary space for visual content.
To do this, you go to the Player Settings > Design Tab.
When you uncheck the Compact Audio Player box and save, the box becomes checked again as shown in the demonstration below.
The reason for this is because when you uncheck the box, an additional step is required to set a new size. Leaving the video at 48px while saving will make Vidyard believe that you still require the Compact Audio Player.
You will need to set a height that is different from the 48px size before saving.
