Well, this is still stumping me. 

I’m using code that has worked in the past on iOS devices.

I’m using “nothing-fancy” .wav and .mp3 files that I have used on iOS devices before.

I have checked the file path and file names—there are no case mismatches.

I ran a check on open card: answer there is a file tFilePath # where tFilePath contains the full path to the file I’m trying to play. The file path is based on specialFolderPath(“engine”)
This check returns “true”.

I verified that the asset files are being copied to the app bundle.

It still plays fine on the simulator and on an Android device.

Has anything changed in terms of what kinds of files can be played on iOS devices? 

Suggestions appreciated.

Devin

It doesn’t seem to matter if I use a simple ‘play’ command or the ‘mobilePlaySoundOnChannel’ command. I’m on Mac Yosemite 10.10.5, and I’ve tried building with LC 7.1.1, 7.1.2 RC2, and 8.0DP14. I’ve tried it on iOS 9.2  and 8.3 on several different iOS devices.
