Using the ALC with Noise Gate on the DA7212 - I'm seeing the noise gate work correctly on startup as the noise is not boosted until a level is reached. However, after sound has activated the ALC, the noise level will not return to the original level (it seems the ALC is still applying some gain when it should have deactivated). I attached an explanation with some pictures and a dump of the registers.
I've tried changing settings all sorts of settings (calibration modes, calibration type and calibration setup, digital/mixed ALC), and have reviewed the reference code.
I attached a short write-up with some pictures.
Any ideas or suggestions?
