The Respeaker Mic Array's AGC (Automatic Gain Control) is turned off, but it has no effect.

I would like to ask for your assistance with an issue we’re encountering. We are using the ReSpeaker Mic Array v2.0 microphone and have noticed that after it receives a strong sound signal, the subsequent sound signals it receives are significantly weaker. However, under the same environmental settings, if we skip the initial step and directly start capturing sound signals, the signal strength is normal. We suspect that this issue might be caused by Automatic Gain Control (AGC), but even after disabling the AGC function on the board, the problem persists. We would appreciate any insights or assistance you can provide. Thank you!
