Using I2S audio output

HI !

I want to use I2s to connect a ES9023 dac to the board. But I don't find the GPIO for I2S and no answer in there forum.
I can see in the schematics "digital audio RXC, TXC, RXFS,TXFS, etc" but which is the equivalent of LRCLK, BCLK, Data, MCLKIN ?

best regards

 

Any one?? :|

 

Or S/PDIF COAX... Devs ? What are you write i2s audio if no one know how use it ? :roll:

 

To be able to extract i2s signal, you should enable the GPIOs by recompiling the kernel, here are some info:

Anyway, once you'll activate the GPIOs you'll need a driver for the exact DAC you want to use... So as of now this is quite unfeasible

As for S PDIF, here are instructions to get it working

Thank you for your answer, I have seen this thread for i2s but I don't know if it's work.

Do you know if volumio kernel is already complied for S/PDIF or I2S ?

 

It is compiled with i2s support, but you still need to find a driver for your specific DAC. And I don't think it exists...

 

Has anyone mooving forward with i2s issue on udoo board?

 

Hello everyone,

I am also interested in getting audio out of UDOO using I²S protocol. Assuming we enable UDOO's GPIOs to properly deliver I²S, we would still need a DAC with UDDO drivers... what about Curryman's DAC also based on the ESS Tech ES9023?
