ATOM_SPK, no sound output

[HappyUser]

Dear all,
I am trying this device : https://shop.m5stack.com/products/atomic-speaker-base-ns4168 using the software from this link (https://github.com/m5stack/M5Atom/tree/master/examples/ATOM_BASE/ATOM_SPK/PlayRawPCM)

This is the message i get when resetting the atom lite :

I2S Write

I know the software is running through some checks in the software i have build in.
But i do not here any sound. No beep at startup and no soumd when i press the button.
This function returns a false : _AtomSPK.begin()
The weird thing is that the definition is : bool ATOMSPK::begin(int __rate) but it is called without __rate defined.
Within the begin function the error occurs in : err += i2s_set_pin(SPAKER_I2S_NUMBER, &tx_pin_config);

Any idea?
Thanks
