    Well thank you for all the past effort put into this modification. I can see that it is well thought out.
    I’ve started on the Jagdroid conversion and am still waiting on parts to do the touchscreen updates, however I have got as far as doing the CD player modifications.
    Some of the things I’ve learned is that a good quality fine tip soldering iron is needed for this mod. I managed to lift a couple of pads off the boards by using an older iron. Anyway once I got hold of a better tool I was able to repair the errors and get things working.

    Well nearly working. The external SPDIF feed isn’t behaving at the moment with just noise when I connect it to the odroid C2 SPDIF output and ground. Not sure whether it is the odroid or the CD player mod at the moment. Sound from the CD is good and the A-MEM switches the relay. I have no convenient way to isolate between the two as my only SPDIF output is the odroid and my only input is the modded CD player.

    There are a couple of questions that perhaps someone has come across.

    Does the odroid C2 always output sound on the SPDIF? Even when no HDMI is connected?

    In the Jagdroid instruction it is a bit unclear on the SPDIF connection because the circuit diagram shows the main board going to relay common and the board on the CD mechanical mechanism going to NC. However the photo instruction shows the common going to “CD transport”. I’ve connected the relay common to the bottom main board. Is this correct?

    Yes I believe you get SPDIF output without the HDMI connected.

    If you are talking about the photo here: https://lh5.googleusercontent.com/ik...6M1XVgz_J=w572 then it shows the Common going to the ribbon cable (on the main board) as per the schematic.

    Not quite sure why you are getting noise, it might be worth checking that the tape isolating the ribbon cable pin is covering the pin correctly, and not and letting the two signals clash with each other?

    Thanks for the suggestion, I'll have a look at the tape or perhaps remove the cable entirely just for a test.

    I couldn't access the image link that you provided, so I'm not sure what it shows?
    I was using the webpage https://sites.google.com/willcoxonli...-player-aux-in and the 29th image.
    The image I was referring to was this one:
    https://lh6.googleusercontent.com/Eo...D7TDp3ql2=w572

    My relay has the common on in the centre between the NC and NO. The image seems to show CD transport on the centre pin.

    Your relay has different pin-outs, the one I link to in the parts list is this one: https://cpc.farnell.com/omron-electr...vdc/dp/SW03294 which has the common pins closest to the coil.
