No, RealSound was not a Covox-like hardware dongle. It was PC speaker only. Play the first few minutes of Mean Streets or Martian Memorandum or Countdown in DOSBox and you'll hear it.

You could play music on the C64 by sampling the tape ports 1bit input and twiddling the sound chips volume accordingly.
You could of course store the samples too, to play back later, but doing realtime sampling into 64KB of RAM didn't exactly let you store much... And a 1MHz CPU didn't let you do much compression if you wanted to keep up..
I did this on an Apple IIe years before I had a sound card on my PC (or a sampler for my Amiga). It seemed so cool to me, even if I didn't exactly understand how it worked.
I know. Experiencing that made me learn about PWM, and I was able to reproduce, harshly, a voice sample on my 2 MHz 8-bit home computer, by bit-banging the tape recorder port's 1-bit output.
