Hello @aksumesh

Thanks for your inquiry.
Did you do git submodule update -i before build?

Best regards

Hi Sir,
Thanks for the reply.
I tried that also.
I compiled inside the Docker also, no help.

Ot says that some error in lines 16 , 17 of the CMake file, pasted below.

Sir, is it possible to make a USB to I2S converter (USB soundcard with I2S output) supporting upto 96KHz, 192 KHz on the Raspberry RPI pico?

Can you please give some directions?

Thanks and regards,
Sumesh
