OWA aka SPDIF
I dont see it on the usermanualare there pin-outs somewhere on the boards? Which model? Sorry I forgot to mention it.
Pi plus or in generaly the H3 boards.
Thanks 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 repoorangepi-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.
