I had some major problems when converting the e/vc workspace into VS2008 solutions. I do not remeber all the steps but start by checking the audio-dev library. Starting in 1.1 there is a audio-dev library. You must convert this workspace and add to your project. Your project must also have a dependency to this lib. Benny has posted the link to the audio updates for 1.1 before. Look there it is not the same as the 1.0.x anymore. /Johan
