I2S to SPDIF

[u301021]

Measured without the 74CH04 = 0 V dc and ac

If that is the case the output is disabled by the software. You have to ask someone on this forum much more clever than me to fix that one.

Ok, but thanks

Try to set the unit into CD mode and see if that changes anything. Could be that the signal
is disabled in other modes, so that it does not create noise that could interfere with the tuner section

When i was measuring, i played a CD

Ok, that is strange. I have never seen this in any I have worked on.

Is it because i not measure with an oscilloscope, and just using this ?

I have one of these cheap ADC like this

Maybe i just should connect that to these points

But i dont think that the TDA1311AT sound that good :-D

Why are you using an ADC for a digital signal?
