Good day everyone,
I tried to configure an ADAU1701 DSP with Sigma Studio 3.15 to stream out an I2S signal.
That is my hardware configuration
and this the schematic
nothing complicated, but I can't get out any BCLK Signal from the DSP. I do see the Master Clock Signal with 12 MHz. The LRClock with 48 kHz and something that resembles DOUT data. But the MP11 the line stays low for all eternity. The RMS meters show movement when I connect an audio source to the analog Inputs, so I would guess that the audio singal is at least processed by the DSP. Still now BCLK output and therefore no sound form my external DAC. Has anybody an idea what I'm doing wrong right now that prevents the DSP from streaming out I2S Audio?
