I want to build a .Net application for processing audio, and distribute it using ClickOnce deployment. I need access to a raw audio pipeline. Which audio library should I be using? I've heard the managed libraries for DirectSound are a dead end. I need as little as possible to be installed on the client's machine. Anything outside of the ClickOnce process isn't going to work.

NAudio might be a possibility, but isn't there potentially a separate driver install? There's also SlimDX.

It's a shame -- the managed DirectX libraries seem to work nicely and from what I've read, DirectX can be included in the ClickOnce install.
