48 is coming from the spdif into the XMOS and 182360( or some similar gibberish) comes out of XMOS

I used the program that you sent me. I changed the .xn file to xk-audio-216, i changed the ports, and i replaced the codec that you had used with cs4384_5368. But the console prints out when building:

09:58:47 **** Incremental Build of configuration Default for project AN00231_ASRC_SPDIF_TO_DAC ****
xmake CONFIG=Default all
Checking build modules
Using build modules: lib_gpio(1.1.0) lib_i2c(4.0.0) lib_i2s(2.3.0) lib_logging(2.1.1) lib_spdif(2.0.2) lib_src(1.1.1) lib_xassert(3.0.1)
xmake: *** [bin//AN00231_ASRC_SPDIF_TO_DAC.xe] Error 2

09:58:54 Build Finished (took 6s.943ms)

Doesn't exactly say what the bug is...

Try to clean project before build or manually delete .build & bin folders.
I use xTIMEcomposer 14.2.4

I can't get 192kHz data with AN00231. Can you solve this problem? Or can you refer me to the program from ffomich? My email address is 604797603@qq.com

I know the app note was not designed to run at 192KHz，but this is what I want to do now.
I tried to modify the program, but it couldn't be implemented, so I hope to get help.

For anyone combing across this thread, just to let you know there is an updated Appnote for xcore.ai running on 316MC board which natively offers 192kHz operation with massively improved control loop (lower jitter) and fewer threads needed due to use of the VPU. It can handle up to 8 channels too (eg. ADAT).
