MediaInfo identifies all lossless 'Atmos' files as being "Meridian Lossless Packing FBA with 16-channel presentation" as well as being "MLP FBA 16-ch"....

That's just the Atmos definition. It doesn't mean the mix contains 16 channels. Its the way the channel data is encoded. "16-channel presentation" is the simplified name

That's the thing, though; I'm trying to figure out why the channel data is having trouble outputting the audio in a 16-channel format.

I guess you've verified the content is actually 9.1.6? Run it through MediaInfo and see what it says?

Your posted bitstream information shows:
Number Of elements: 12
Channel distribution: Disabled

That is exactly what the decoder is doing. Creating 12 channels (7.1.4) without distribution to the additional channels for a 9.1.6 decode.

Case solved.
