1 3DS XL has no sound nor mic input
Hello ifixers, 3DS XL has no sound, neither with internal speakers nor headphones. Microphone also does not work. I restored system but the issue persists. For headphone jack I test a difference in continuity when a jack is plugged and not (I guess headphone port seems to "switch" all right). I cleaned volume slider and it seems to have an effect because I can see the volume icon symbol going up or down in music player when I slide it, but still no sound output whatsoever. What should I be doing next? thanks for any clue

Hi! So, only the sound failed? It's probably motherboard related :(. Is the 3DS XL modded by any chance?

Hi, no it is completely stock, both at hardware and software levels

I’m afraid that the sound IC failed. Do you have any soldering experience? If not, you could replace the motherboard for a new one, but this is more expensive. Let me know if you need guides!

@dan0 I came to the same conclusion. Texas Instrument AIC3010D seems to be a BGA chip. If I can find a balled new one I think I can manage it. Putting balls on it I've never done that and honestly it seems a PITA. Do you have a good source for such a ready to solder chip please?

Can't say for sure :(. I would buy a broken donor motherboard (with a different issue obviously). And get the IC from there. Maybe @oldturkey03 knows a place where to get those IC's from. Sorry!
