Some Questions

I was looking at the documentation for sound and there doesnt seem like there is much. I am looking for something like FMODs sound channels. So than I can just easily the sound volume for all: music, sound effects and dialog as well as master volume. There also didnt seem anyway to muck around with the pitch (though its less important).

How do most people handle it, some sort of sound manager script?

I am also looking for a combobox?
And a way to make the configurable input in the browser.

I have two scenes. Main Menu and the game level. I want to keep both of them in memory (so you can press “escape” and go back to the main menu). Than in the mainMenu press the resume button which would simply switch states back to the game but there doesnt seem possible.

AudioSource does actually have a pitch property. Also, have you seen the free FMOD plug-in?

There’s no combobox control as such in Unity, but you might be able to put something together using the GUI system.

Do you mean you want to let the user redefine the controls (keystrokes, etc) from a web player?

You can switch between scenes using Application.LoadLevel. However, the loaded scene completely replaces the current scene, so you can’t temporarily switch out of a game in progress and then switch back. You can use the GUI system to display a set of menu options briefly without changing scenes.
