I found that Safari Technology Preview "decodeAudioData" is not able to decode mp4a fragmented (non-fragmented files work fine).

Example code:

You should be able to see "CAN PLAY" alert, but since "decodeAudioData" is never fired then you will not see this Alert.
Chrome / Firefox / Opera is able to decode the data correctly and the callback decodeAudioData is fired.

Thank you for the report!

Just to clarify, are you also seeing this with shipping Safari? It seems to reproduce in shipping Safari for me.

yes it is reproducible even in iOS9/Safari.
