As far as I know, even on IOS, the EAC3 codec is supported for native playback on the operating system.
However, for some reason, the EAC3 codec is transcoded to AAC on IOS.
I had the same issue on Android, but changing the client settings from web player to integrated player solved it.
However, IOS does not have the same option.
Can you tell me why the transcoding is happening or how I can prevent it?
