If you have a soundcard and speakers capable of 5.1 sound, this can be enabled 

via the included DirectSound output plugin:

 1. Set the correct speaker setup configuration in Windows, and set hardware 

    acceleration for audio to 'full' via Windows Control Panel > Sounds and audio 

    devices > Speaker settings > Advanced)

 2. Go into your soundcard's control panel and make sure 5.1/7.1 speakers are selected

    instead of stereo speakers.

 3. In MediaMonkey, go to Tools | Options | Output plug-ins and set DirectSound 

    as the output plug-in if it isn't already.

 4. Click the 'Configure' button to configure the plugin and enable hardware acceleration

    (in MediaMonkey 2.5 you'll need to switch to the 'Device' tab).

 5. Make sure your sound card/chip is selected as the Output Device.

Any changes will take effect after playback is restarted.



Note: If the 'hardware acceleration' checkbox is greyed out in MediaMonkey 2.5, make 

sure that the sound card drivers are up-to-date.



If that doesn't work, try upgrading to the latest version of DirectX at:

For Creative SB Live & Audigy sound cards, try enabling CMSS in the EAX Control 

Panel, and remember to move the Front/Rear slider down (e.g. from 100% to 0%).



If that still doesn't work, you can try the following alternative output plugins (untested):

 o Wave 5point1 plugin: http://www.winamp.com/plugins/details.php?id=122003
