The original IBM PC had a speaker in it, that was driven simply by connecting one lead to an I/O pin and the other to ground. The speaker could be driven only by a square wave. The sound waves were simply converted to a square wave turning the I/O pin on and off.
This hopelessly crude device worked rather amazingly well. Certainly far better than the sound samples in the link. I wonder if that technique could be applied to the implants.

Instead many nerves exist, each representing a specific combination of volume and pitch. These implants can't precisely target the nerves though, and end up hitting a random selection of nerves. That's the core of the issue.
