I have an activity that uses Connect-Rest to call Azure Speech service and convert text to voice. The result of the activity is a Base64 encoded mp3 string (please check the attached screenshot) that I want to show it in UI as an audio file.

This doesn’t work for me. Please let me know if you have any ideas.

<audio controls src="data:audio/mpeg;base64,T2dnUwACAAAAAAAAAAA+..........+fm5nB6slBlZ3Fcha363d5ut7u3ni1rLoPf728l3KcK" />

We need some more details to help you. What part is not working for you? Is the element present in the HTML as you expected? Is the audio control rendered? What happens when you press the play button? Have you tried with hardcoded base64 string? Have you created a HTML rule for this or some other configuration, can you share this? Have you checked the developer tools (F12) for error? Do you have a more elaborate example to share? Have you tried on various browsers and devices? Do none of them work?
