I just got a simple Music Visualizer running on Zune (Modified version of the one found in the documentation). It works great, love it. Except for the fact that I don't see any way of controlling the Device Volume.

I can easily control the media player volume, but this cannot change the overall volume of the Zune it can only make the Zune quieter than the currently set Device Volume.

I was wondering if there is any way to change the device volume within a game, because it is sort of jarring to quit out of the game just to change the volume. If not is there any chance of this being added in the future? I'm guessing Zune Games aren't supposed to be able to access any system settings, but it would be nice just to have a true volume slider.

Would this be it? Its in the XNAdocumentation                                                                                                              ms-help://MS.VSCC.v90/MS.VSIPCC.v90/MS.XNAGS30.1033/XNA/Audio_HowTo_ChangeSoundVolumeLevels.htm

1. _{Create an AudioEngine, WaveBank and SoundBank at game start.}

2. _{During game update, call the Update method of the AudioEngine to allow the audio engine to process audio data.}

3. _{To retrieve a category of sounds whose volume you want to change, call AudioEngine.GetCategory and pass in the name of the category you created in the XACT project.}

4. _{Call AudioCategory.SetVolume on the retrieved category.}

5. _{Specify the desired volume, which typically is between 0.0f (silence) and 1.0f (full volume as authored).}

6. _{To make the volume louder than designed, pass in values greater than 1.0f (for example, a volume of 2.0f adds +6 dB to the authored level).}
