I have a problem about Jetson NX audio.
I designed custom NX carrier board for our customer. The carrier board has an audio codec(SGTL5000) so I modified device tree for it(not overlay method). The codec work find util commercial USB audio codec plug & unplug.

And also I tested overlay method it has same result.

SGTL5000 codec does not work (No sound )after rebooting. The only way to resolve this issue is full flash using flash.sh.

I haven’t been able to figure out the exact cause yet, but it’s not a hardware issue I think.

Seek help from those who know about it.
