I’m playing with an i2s source with only 3 wires. B clock, Word clock and Data. On my TDA1543 DAC with i2s input, I see 2 GND lines. I just ignored them.
There’s no music coming out. I can only hear shhhhhh noise. Any ideas ?
There is no such thing as a voltage. You have also just discovered that there is no current without a circuit. Mr. Kirchoff had something to say about these two issues.
