Select Audio Track of Video on iOS

I have an MP4 film that has 2 audio tracks, the normal one and one with director commentary, when I try and watch the film on my iphone the app is auto selecting the directory commendtary track but I dont know how to select the other track. Any ideas?

If you updated the app today, you can’t. The feature is gone.

I don’t think I answered the root of your question…

Is the Director’s Commentary the 1st track?   The app plays the first track by default.

I probably have 60-70 videos with multiple audio tracks, and I haven’t (yet) noticed it playing anything other than the first track.

If the commentary track is NOT the first track, then please post the full TEXT output of MEDIAINFO for one of your problem files.
