Hello! That's right, I experienced the same issue on a few games with the mGBA port on 3DS. I believe it happens because of a frame rate drop in some games. The most obvious example I found is in the game Crazy Taxi where the frame rate falls under 40 fps instead of 60 fps, but also in F-Zero Climax (around 50 fps), and a few other games in which the frame rate drop is no so huge, around 55fps: F-Zero Maximum Velocity, Metroid Zero Mission and probably others. In these games the emulation speed doesn't seem affected much visually but the sound seem choppy indeed. Is it technically possible to improve the emulation speed on the 3DS port of mGBA? Or maybe at least could it be possible to use the extra power of the New 3DS to improve the emulation speed for the New 3DS owners?

mGBA already uses the increased clock speed and L2 cache on N3DS. Unless endrift got another trick up their sleeves there is not much that can be done here.

If you don't care about save states, button remapping, cheats and other convenience features and just want speed you can try: open_agb_firm. Keep in mind it's alpha software. Read everything carefully and expect bugs.

Thanks for your answer! I didn't know about that open_agb_firm. It seems promising even if it's in an early stage of development right now. I might give it a try.
