MonoGame 3.7.1

Hi, I experienced a weird issue, trying to playing Songs under iOS.
I imported my_song.mp3 file via content pipeline (using “Mp3 Importer - MonoGame”) and load and play it as follows:

Song msx = Content.Load<Song>("my_song");
Microsoft.Xna.Framework.Media.MediaPlayer.Play(msx);

All the things goes well, no errors was generated and the Microsoft.Xna.Framework.Media.MediaPlayer.State is “Playing”, but no music is audible (of course, the volume is correctly set…).
I tried with various format of mp3 and also with .ogg, with the same result.

I tried to downgrade to release 3.6 and the above code works well. In simulator and in real devices the songs play fine.
So, it’s definitively confirmed it’s an issue of the latest 3.7 / 3.7.1 releases of monogame.
I am very curious to discover the reasons of this bug…
Nobody can help us?

I reported this issue also in the topic: mp3 Songs won't play on iOS
where no solution was proposed.
