Bingo! That did it. I switched the HDMI Input Audio Format from Bitstream to PCM. That seemed to have solved it.Not sure if this will help, but something similar happened to me as well with my B8 and a soundbar.
What helped me was entering the audio menu of the TV, and then fiddling around with settings such as "uncompressed" and the like.
I simply tried random things there until I got sound.
Did any of the other discs use DTS HD? Maybe it has an issue with it? The ones you mentioned are all Dolby Atmos.
I'm wondering if this was the underlying issue. The switch to PCM seems to have solved it. I'm gunna go back and test the other discs I've already played. I only say this may have been the issue because I also tested the other Nolan flick I have currently, Inception, and it didn't work while using Bitstream, but works with PCM.
