Nano audio codec not detected

Hello John,

That error can be normal. The error code -517 means that the probing of the codec is being deferred because some dependency (clocks, resets, etc) are not available yet and will continue to retry probing it. So check the debugfs node again for the codec and see if it is there …

$ sudo cat /sys/kernel/debug/asoc/codecs

Regards,
Jon
