I broke the audio on my steam deck doing a shekl swap. It has to be a hardware issue but i took it apart and back together again like 3 times. Oh well, i got a aya neo geek 1s on the way, im sure ill miss the deck and continue to use bluetooth audio
I gave it a good look and you’re right im not finding a replacement for that part anywhere. I reckon next best option is scavenge it from a broken deck or send it to valve for repair at cost
