Hello fellow tinkers!

So I disassembled my Steam Deck to put in some ExtremeRate buttons. And after assembling it again I had no input on the volume buttons or any output/registered headphones from the jack.

So I bought a replacement audioboard and just switched it. Still no input or output. I checked the connections of the flex cable on the audioboard and it is good. The same for the connection under the heat sink on the motherboard. There is also no visible signs of kinks or tears in the cable.

So what am I missing ? Is there some hidden connection somewhere I can’t see that could have gotten loose ? I would really like to fix it myself if possible and not have it send in for repair.

Hope anyone can help !

Edit: My deck is the revised OLED, so it only has the one flex cable connecting the audioboard and the motherboard.

And for some reason the microphone still work. Which is weird since I thought the mic was connected via the same cable.

Edit II: For anyone following along, it was the ribbon cable that attaches to the audioboard, that had a detached connector. By applying a little bit of force on the ribbon cable the connection is restored, so I used my high tech super powers and fashioned a bit of cork to go in the back plate to apply a little pressure. It works but would not recommend as a permanent solution haha.
