TAS5825M: initialization code

Part Number: TAS5825M

Hello!

I try to initialize the TAS5825M without PPC3 but I get no output.

The I2S clock is stable (96 kHz, ratio 64) and a I2C register dump of page 0 shows that the register values are in principle fine (no faults, PVDD ok). The only strange thing is that the DIE ID (reg. 0x67) returns 0 instead of 0x95.

I checked all supplies and they are also ok: DVDD, VR_DIG, GVDD, AVDD.

I write following registers (reg., value):

0x00 0x00

0x78 0x00

0x03 0x03

0x78 0x80

Any suggestions what else I can check? What could go wrong?

Thank you!
