360 AP1PA3 Streamer audio input codec setting,only G711A work

In the tinycam app, the camera can only work properly if G711A is set. After selecting other codes and clicking the speaker button, the interface will keep spinning. The 0216 version is normal.
In addition, when using G711A, the speed of opening the audio 0421 seems to be a few seconds slower than 0420.
(I have tried the firmware in the past few days and only G711A works properly)

Audio start time:
0420<1s,
0421>6s (the sound also has a delay of more than 6 seconds)
