IFF-AFF

These files contain at 3 different moment the physical DSP state and matrix values. If the matrix values are correct on that files if means that except a DSP bug or physical default on audio device, the sound should be sent out/listen to.

A very important information that  gives you DSP alive status is found editing 2 different dspconfig.status files (you’ve 3 dspconfig.status file in a debug information zip of a EK model).

File 1: GENERAL STATUS DSP interrupt counter : 1946314

File 2: GENERAL STATUS DSP interrupt counter : 1947422

Both value must be different and file 2 value will have a greater value than file 1 value. If both value are equal the DSP is dead.
