Mic is muted when play music while broadcasting

Dear all,
I make a broadcast stream (voice and video). The audience can subscribe and play perfectly (can hear voice and see video)
But, I open the music player on the phone that makes the broadcast, the mic is muted. The audience can see video only. We cannot unmute the mic again by “send config”. We need to destroy broadcast and make another one
Some guys has solution for this case?
