I am working with a device that has been using the WM8731 audio codec.
This device has been obsoleted by Wolfson (and Cirrus Logic).
The Ananlog Devices SSM2602 is pin compatible and the configuration registers are almost exactly the same.
If I simply "swap" the SSM2602 onto the board instead of the WM8731, it works fine, with one small exception.
There is a low level whistling noise that is audible with no input audio.
Analog Devices support has not been able to clearly define what factors make their device more susceptible to this issue than the WM8731.
Has anyone experienced anything similar?
