OK, Now I suggest

1, Connect the BII directly to the FIFO board I2S output port rather than the clock board to see if it's working

2, replace the double xo clock board with the single xo clock board (with onbord 11.2896 xo) , play 44.1K audio to see if there is sound.

Good luck.

Ian

Yes, Yes, Yes...!!
It plays sweet music without the dual clock bord and also with the single clock board!!

So the problems seems to be the dual clock board.

What can be wrong with the dual board?

Ian,
I just noticed that it does not play or let the I2S signal go through to the BII dac without the 10-pin FPC/FFC cable connected to a clockboard. But perhaps it exchanges some signal necessary for the Fifo board.

Good night !

Congratulations, Karvid!

Yes, the FPC/FFC has control signals inside, so, it won't work without it.

I ordered the toroid from China who has very good reputation in custom made toroid for DIY. The 80VA cost me US$50.

What are the voltages if you don't mind me asking..

Also,
Are you using a pot or encoder for volume control ??

Thanks Ian,
will the jitter eating Fifo work even without the clock board?

I could then for the time being play without the clock board all my 192kHz files. With the single clock board I will be rather limited.

But what about the dual clock board?
