stereo and lack of 5.1
So I have a problem with som movies in my iTunes library. I'm watching them on AppleTV app on Amazon Firestick 4K. Some of the movies play in DD+ 5.1 as they should but some only in stereo. The last two movies I purchased (Top Gun and Die Hard with a vengance) play only in 2.0 yet they are listed on iTunes to have 5.1 tracks. Is there anything I can do on my end or is it up to Apple?
