If i would play a two audio in sequence in background on iOS how can i do?

If i play only one audio i background the plugin work fine, but if i try to play 2 audio in sequence, the second don't start, why?
while it works fine on android, have to add anything else on iOS?

I tried this plugin https://github.com/AubreyHewes/cordova-background-audio but dosen't work.

Do you have any idea?

No error in Logs

Thank you
