Audio Channels (For Windows® Vista/ Windows® 7 only)
This setting only appears in Windows® Vista/ Windows® 7. Windows® Vista/ Windows® 7 delivers
the audio channels to the audio driver according to this setting, no matter what the original audio
content is or how many channels they have. Therefore, you need to set this in accordance with your
audio content before you play it. This setting is synchronized with Windows® Vista/ Windows® 7
system speaker configuration and changing the setting during playback stops the audio playback
program. You may have to restart the program after changing this setting.
Close all running applications before changing this setting.
