How do I play .mkv files on iPhone 7 with DTS sound?
“Hey there, I was really excited to use my new iPhone 7 to watch movies. I put a few 720p .mkv’s on there. There are no flaws in the picture at all. It looks to be playing flawlessly. However, there is no audio whatsoever. I tried multiple .mkv files, on both my iPhone 7 and my wife’s iPad. On both platforms there is no audio. Is this a Dolby or DTS issue? How do I play .mkv files on iPhone 7 with DTS sound? Please do advice how I can overcome. Thanks.”
