[SOLVED]: I2S Driver for TDA1541A
#7
I hooked up the system again the following configuration:
TDA1541 <-> RPi2

1 - LE/WS <-> J35 (PCM_FS)
2 – BCK <-> J12 (PCM_CLK)
3 – DATA <-> J40 (PCM_DOUT)
ALG GND <-> J39 (GND)

Used the Generic-1 I2S (hifiberry-dac) driver as recommended by Tim.

I am tapping on the TDA1541A with the CD player in place so that it can supply the necessary power supplies.

I played a 44.1/16 .WAV file, but there is still no music output.

Any other suggestions?

UPDATE: I tapped the TDA1541A inputs before the resistors marked in RED. Could the GPIO voltages be attenuated too much? See attachment
