Hi, my 3ds plays sound fine usually, but in twilight menu it only plays it through headphones. This issue doesn't happen anywhere else. Can anyone help me?

Sorry for taking a while to reply. It happens in all of them. Is this a problem with my software? It doesn’t happen in any 3ds stuff.Please check if the issue happens on actual DS(i) game cartridges, your installed DSiWare titles, and/or in DS WiFi Settings and DS Download Play menus.

Check if you're able to change DS Profile settings in System Settings. (Other Settings -> Profile -> Nintendo DS Profile)Thanks for replying. It still hasn’t fixed the problem. Do you have any other ideas?
Yes, I canCheck if you're able to change DS Profile settings in System Settings. (Other Settings -> Profile -> Nintendo DS Profile)

If you actually changed/reverted the profile settings, and the issue persists, then I think you're out of luck.Yes, I can
