Guys,

I've tried :

DAC/DualModeDMA_SineWave/main.c   

* @author  MCD Application Team

From Standard peripheral library, I can see it already on the osciloscope,

how can I make it audible ? How can I adjust the frequency ?

thanks

No need for work around, a LM386 will work if used correctly. Did you add a low pass filter? Show the circuit diagram (else we are all just guessing what you've done wrong).
