Thank you for your answer! It was really helpful
Now I can send a recorded file to TV by chunks. It is strange because TV recognize voice when I send file by 120 bytes but TV can't recognize if I send by 119 bytes. Maybe you know this issue and can help. However I can do it with recorded wav file.
My next question is about realtime audio stream. Do you know how it can be implemented?
I will be really grateful for your additional help
