  • CTAG-Face error message revealed with dmesg

Hi @henrix,

I turned on CTAG-Face and check the system message using dmesg command and found an error
snd_ctag_face_2_4 ocp🔉 snd_soc_register_card failed (-517)

What should I do to solve this problem?

please use triple backticks (```) to enclose your terminal output ( I amended it for you above).

Does the soundcard work when the error is dislpayed? That looks like a harmless warning, so I wouldn't worry too much if it indeed works.

I will do the backticks next time

No. there is no sound with the second DAC (DA2) when the message appear, I did not manage to co-relate the aural problem with the system message in my previous post, but this one I did.

  1. I turn on the system
  2. Load driver, run jackd, and use jack_connect to link my program
  3. DAC1 has sound, DAC2 has no sound, open dmesg ... this time two errors

Please note the above is one instance of the startup process time, the whole picture is that the chance of error occurance is 30%, which means it fail every 3 times in 10, and the other 7 times works perfectly, and when it works it can works perfectly for many hours.

    ok, let's wait for @henrix. can you post the full sequence of commands, so he can reproduce this step by step?

    Hi moseswong001 ,

    Error 517 means probe deferred (https://github.com/torvalds/linux/blob/master/include/linux/errno.h#L19).
    Thus, you can ignore this error. If you can list the audio cards via aplay -l, the kernel modules were loaded correctly.

    Have you checked if all audio card channels are unmuted?
    You can do that using alsamixer or amixer.
    Moreover, there seems to be a port mapping issue of the JACK config in the current image:
