if it is not too late, make PA17 accessible or at least confirm that it is not possible.

Thanks

i have OPC and i am also very interested in SPDIF output... would really appreciate any hints on this. Where is PA17? Is it posible to connect coaxial to that pin?
Thanks

I have an OP Zero 2W and I see in the H616 manual that it should have the OWA block (spdif output) on pin PH4. This pin is available on the gpio 40 pin connector on pin 18. I see that for the H5 based boards, there is the dt overlay available in github repo orangepi-xunlong/linux-orangepi : sun50i-h5-spdif-out.dts.
I tried to modify the H5 overlay to suit the H616 base devicetree, but I get 'not found' errors. The error doesn't say _what_ it cannot find.
See the attached spdif.dts. Can anyone point what I did wrong?
Also I guess the ahubdam needs to arrange the 'connection' to the OWA, but I cannot see something obvious I should set in the alsamixer.
