HTML 5 Audio Tag issue in iOS

I am having an issue with the following html:

<audio
id=“questionAudio”
controls
controlsList=“nodownload”
style = “min-width: 308px; min-height: 69px”
[src]="‘data:audio/ogg;base64,’ +questionnaireData.allQuestionProperties[currentStateObject.position].audioFileRawData">

I have audio stored as binary that is dynamically loaded based on which “question” is being asked to the user.
The code works fine in Chrome while testing.

Figured it out. iOS was more sensitive to type. Needed to change to audio/mp3.
