well i connected the EVAL-ADAU1761Z to raspberry pi i used this also https://ez.analog.com/linux-device-drivers/linux-software-drivers/f/q-a/111524/adau1761-on-raspberry-pi3/334051

but no success

aplay -D default:CARD=Seri MONO-000.WAV

    Hi,

    First good thing that I see is that you have bcm2835-i2s-adau-hifi card. That's perfect.

    Now next step would be to check with an oscilloscope if you have the I2S clocks/signals available. I2S_BCLK, I2S_FS, I2S_DIN, I2S_DOUT.

    Also what's the position of S5? It should be in DOWN position.

    Also based on what's your output data source on RPi->alsamixer->ADAU1761 card you have to select in DAC Playback Mux -> DSP if you have loaded a DSP firmware or AIFIN if there is no firmware and you want just to output the I2S data.

    Regards,

    Bogdan
