The sound does not work on my 3DS XL.

The speakers were cutting out for a while, but now they don't work at all. I tried ear buds to see if it was just the speakers, but there is no sound coming out of there either. There is no tutorial on how to fix the sound, just the mic. Will fixing the mic take care of the sound as well, or is there a way to fix the sound on its own?
