Sound only playing through headphones

[takaoandrew]

Does anyone know why this might be happening? I have tried to use this package on multiple ios devices and the sound only plays if there are headphones attached. Works fine on android. Is this some sort of permissions issue?

My only guess is that the file type (mp3) is only able to play through headphones. I am downloading mp3 files from firebase and playing them locally. My log messages look the same whether the headphones are plugged in or not.

With headphones, sound plays:

Without headphones, no sound in speakers:

I have no idea why this would be the case, it makes no sense to me.

Also, I don't have any iDevices to test with, maybe @feroult can help us out?

@takaoandrew Could you try to test with other file formats to test your theories about MP3? That would narrow it down a lot (maybe wavs, oggs, etc will have better results).

Fixed by #41. Thanks @tsun424!
