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).
