My OPN miniRITE is not outputting sound

My OPN miniRITE is not outputting sound but when I check it on my cell phone, it is on and not transmitting sound. It was after I turned them off one day and the next day they no longer turned on.
I already changed the receiver on one of them but it didn’t solve the problem. Does anyone have an idea what it could be?

Will it stream sound?
If one aid is working right try temporarily swapping receivers.

it is not transmitting sound. I already replaced the receivers and it still doesn’t make any sounds
