Hi,  
my configuration is: phone -(via bluetooth)- BC127 digital audio output (I2S) - I2S amplifier (MAX98357A) + speaker  
AUDIO=1 1  
AUDIO\_DIGITAL=0 44100 64 100A00 ON (I2S MASTER)  
Also I have tried different ROUTEs but I don´t get any music playing.  
Is this configuration right?

I had this problem with the PCM5122A – it was a faulty I2S configuration on the Melody side. I suggest reviewing the configuration bits for AUDIO\_DIGITAL against what the MAX98357A expects.
