No smoke. Yeeej.

Green flashing LED near power connector. Is this good Sören?

sounds really relaxed, present and musical playing over my AckoDac AKD12, Ian FIFO, dual klock board, selected NKD wissler.straigth into a pair of nCore 400/SMPS600 and a pair prototype speakers.

Lets change DAC.

No sound. No strange noise either. Dead silense. Now someting to eat.

For newer versions of the Amanero pins 17-20 are no longer ground but the sample rate indicator, see attachment at post (http://www.diyaudio.com/forums/vendors-bazaar/259488-reference-dac-module-discrete-r-2r-sign-magnitude-24-bit-384-khz-91.html#post419713).
As far as I can see from your pictures you seem to have conneted one of those pins to the I2S inputs of the DAC.

(Hence a wild guess: flashing green LED means no imput detected)

Powered up, but not locked (no signal). LED turn steady when locked.

Make sure it's wired correctly and power is supplied to the isolators.

On the Anamera there is a +3,3 V pin. I tied that to the iso 3,3v pin on DAM.

But I mesure 0 to gnd.

[TNT]

Dont know what happen there really but now there is 3,3 volt for the isolator. Still grenn blink.

I measure all OK on J2!

Check wires again. If everything looks ok, post a picture with both boards and wires clearly visible....

What I have on the signal pins:

in rising picture no order...

data ...7
lrck ...8
bclk ...9
bclk again ...10

and the pics

Data stops when hitting pause.

Setting says:

44,1 khz 32 bit integer.

Cant seem to change 32 bit integer...

[soekris]

1V P-P on the signals ?? Should be 3.3V P-P.... Sure you got power on the isolators ?

Can it be default Amanero Firmware configuration? (Red arrow in the attached screenshot.)

 

[TNT]

Isolators. Several? How to measure?

Sören, would this be a problem?

On the dam1021 R-2R DAC, measure power between "ISO +3.3V" and any "ISO GND".
