--- Comment #12 from Roman R. <roman at alax.info> ---
Audio junk is played from an asset that has video track only. We generate the live data programmatically and by no means the data could have an audio track. Additionally, addSourceBuffer call argument has no reference to audio.

Also audio problem has nothing to do with sdtp boxes, their removal left the audio bug in place.

We do not set duration and it is updated according to MSE duration change algorithm (presumably). In the same time duration embedded into FMP4 is zero to indicate live stream. 

So I thought that yes there is a chance that Safari does not have a notion of duration-less stream and pauses on considering reaching EOS, what browsers like Chrome and Firefox would not do because they see the stream as live and keep playing just waiting for content appends. I will look into that a bit more.
