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
no sound comes out
here is pcm list

I think there is a connection problem.
Can you please list here how you connected the EVAL board to RPI. I mean what pin from RPI to what pin from EVAL.
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.
here is channel 0 gpio 18
channel 1 gpio 19 Connected to LRCLK
and channel 2 gpio 21 connected to DAC
here are the i2c commands
I looked over your mixer configuration and saw some problems.
Switches "Right Playback Mixer Right DAC" and "Left Playback Mixer Left DAC" are set on "false".
Please open alsamixer navigate to before mentioned items and activate them (press M key).
Also if in your DSP program you don't have I2S inputs configured you should set the DAC Playback Mux to AIFIN and not DSP.
well i tried it with no result what so ever i even used the mic input same thing
are the i2c command right ?
i'm using this device tree maybe it's wrong
