The root cause is that there was a stream which wasn't resumed by the AudioContext because that stream was not belong to a Node, which resulted that AudioContext can't get it when calling `GetAllStreams()`.

The stream is created by the AudioParam [1]. Therefore, this stream blocks other streams which were connected to the GainNode, which resulted that AudioContext didn't output any sound.
