MP3 Content Type for Creating a MediaSource

I am using Azure SSML TTS to get a C# Stream object in "audio-16khz-64kbitrate-mono-mp3" format and other customizations. I subsequently create a byte[] stream from it for cross-platform Xamarin distribution. For UWP I convert it to a InMemoryRandomAccessStream to use with CreateFromStream to create a MediaPlayer.Source from a mediaPlaybackItem.
Using MediaSource.CreateFromStream(stream, content type), what is the content type for a "audio-16khz-64kbitrate-mono-mp3" stream? I have tried numerous values which result in the mediasource not being created.
I have also tried using stream.AsRandomAccessStream with the received stream to create the mediaPlaybackItem without using the byte stream approach with no success.
I know the stream is valid as it is not null and playable on Android devices.
