I'm no hardware guy, but from what I understand, doing the audio is much simpler. It reads some memory registers from the RAM, but then it does something independently from the rest of the computer, and the audio output is also independent.
For sprites, you'd have to have a completely different TED though, I think. There's no way to "add" something else to the screen that is getting generated. It's not like you could have an "IF" to check "is there a sprite here?", etc. So, I'd say something like that is "impossible", or rather, cannot be done with a simple extension card.
Well, maybe someone more knowledgeable could either correct me or explain it better.
