Changes under Vista: 
1. In Windows Vista, when changing the Speaker Configurations (on the Main tab
   in the Montego DDL Control Panel), a User Account Control ("UAC") window
   will appear asking for permission for the "Turtle Beach Audio Configuration
   Tool" – this is an operating system security feature that is new to Windows
   Vista.  In order for the Montego DDL Control Panel to make the Speaker
   Configuration change you desire while Vista's User Account Control is 
   enabled, you have to click 'Continue' on the User Account Control dialog 
   that appears. Since the Montego DDL Control Panel is scheduled to run 
   automatically following the installation of the driver, this UAC prompt 
   will be seen when the desktop is loading – 'OK' must be clicked to allow 
   the Montego DDL Control Panel to set the default 5.1 speaker configuration.

2. Due to changes in the way the hardware works in Vista, there are now 2 DDL
   modes to choose from - "DDL 5.1 Encoding" and "DDL Stereo Encoding".  
   The end result of both modes is the same – encoded 5.1 Dolby Digital Live
   output from the S/PDIF output.  The use for each depends on what type of 
   audio is being played. In XP/2000, when DDL mode is selected, stereo audio
   is "upmixed" so that it is sent to all speakers (not just the Front Left 
   and Right), and 5.1 audio is encoded "intact" into a Dolby Digital stream.
   Under Vista, the "upmixing" required the creation of the new "DDL Stereo 
   Encoding" setting – this is what should be used to allow stereo sources 
   to be pushed out in DDL mode to all 6 channels of a 5.1 system.  For audio
   sources that have discrete multi-channel audio (such as most popular PC 
   games), the "DDL 5.1 Encoding" setting should be chosen to ensure that the
   placement of each of the 6 audio channels is correct in the encoded DDL 
   output.

   NOTE: 
       When DDL modes are used, the Windows Vista Playback Devices should 
       have "Speakers" (not "Digital Output") selected as the default 
       Playback Device, even though the S/PDIF connection is being used.

3. "Stereo to Multi-Speaker" no longer occurs automatically in Vista.  For
   example, under XP/2000, if 5.1 Analog Speakers are used and a stereo MP3 
   file is played, the original 2 channel MP3 is "upmixed" so that sound comes
   from all 6 speakers.  Under Vista, the Speaker settings on the Main tab of
   the Montego DDL Control Panel function a little differently.  

   EXAMPLE 1:
   Selecting "5.1 Speakers" enables all 6 analog speakers so that the audio 
   from 6 channel sources can be heard in the proper output channels, but 
   does not automatically mix stereo audio to all of the speakers (that is, 
   a stereo file will only be heard from the Front Left and Right speakers).  
   In order to mix and match the number of audio channels with the number of
   active speakers, the Speaker Positioning (on the Effects tab) must be 
   enabled – this will expose a new control specific to Vista that allows you
   to "tune the speaker mix".  This is best explained with a couple of
   examples. If you wanted to listen to stereo MP3 files played through all 
   speakers of a 7.1 speaker system, enable "7.1 Speakers" on the Main tab, 
   then enable the Speaker Positioning on the Effects tab and choose "Stereo 
   Sources" from the 'Speaker Mix Tuned For' drop-down menu.  The virtual 
   speakers can be dragged around to alter the room sound, and the individual
   volume sliders on the Main tab can also be used to adjust the overall
   volume of each of the channels.  

   EXAMPLE 2: 
   If you are using stereo headphones and want to hear all channels of an 8 
   channel audio source in a more "spatially correct" manner than can normally
   be produced in stereo headphones, enable "Headphones" on the Main tab, then
   enable the Speaker Positioning on the Effects tab and choose "7.1 Sources"
   from the 'Speaker Mix Tuned For' drop-down menu.  Once "7.1 Sources" has 
   been enabled, adjust the speaker icons to create a better sense of space
   (i.e., move the front channels closer, move the surround channels further
   away, etc). Most simply put, when Speaker Positioning is enabled, the
   Speaker setting on the Main tab controls how many physical speaker channels
   are "open", and the 'Speaker Mix Tuned For' drop-down menu controls what 
   the number of channels the source audio has.  This allows for large number 
   of flexible settings. 

   NOTE: 
       The amount of speakers shown on the Speaker Positioning window will 
       always show which value is greater – the number of "source" channels 
       or the number of active physical speakers).

4. For proper Dolby Digital or DTS pass-thru to an external decoder (such as
   an A/V receiver), the S/PDIF setting on the 'Speakers' tab of the Montego
   DDL Control Panel should be set to "48 kHz"; additionally, you must set 
   the Digital Output as your default playback device in the Vista Sound 
   Control Panel.  Click Start > Control Panel > Sound and select 
   "Digital Output - Turtle Beach Montego DDL Device" as the Default Playback
   Device.

   a. Note that the Digital Output will be automatically selected in the Vista
      Media Center Setup Wizard if "TOSLINK" is selected as your speaker 
      connection type.
   b. Also note that in this setting, the S/PDIF Output functions strictly as
      a pass-thru – Environment effects, EQ and Montego DDL Control Panel 
      Volume Controls don't have any effect on the audio.

5. Making Speaker Configuration changes in the Montego DDL Control Panel while
   audio is playing may require restarting the audio application. 

6. If Voice Morph or Mic Echo is enabled but doesn't seem to be working, 
   make sure that the Microphone is set as the default Recording Device in 
   the Vista Recording Devices dialog box.
