Hi Ernie, You should be able to download and use the tool below to generate 7.1 channel test audio: http://www.microsoft.com/downloads/details.aspx?FamilyId=72F6F2FA-0ABE-4A92-9DD0-FD35B966825C&displaylang=en If you want more details on this then goto: http://www.microsoft.com/windows/windowsmedia/howto/articles/creating71audio.aspx This will provide you enough information to generate the test audio. You should be able to use "Winamp" as a test tool/application for multi-channel audio. Thanks, Neetu.
