HI
Did you find a solution ?
I made a new project in openstm32 and get sound to work perfect...
Now i want to add FFT from cmsis and i did ;

1. include “stm32f7xx.h”
2. include “stm32746g_discovery.h”
3. include “main.h”
4. include “math.h”
5. include “arm_math.h”

but iit fails here

arm_fir_init_q15 (&SFIRleft, NUM_TAPS, firCoeff, pFIRStateLeft, NUM_SAMPLES);

and i did add ARM_MATH_CM7 to the SYMBOLS tab in project properties paths and symbols

What did i miss ?
