I have been running ATI All-In-Wonder 9000 Pro for about 2 months with no problems, but I recently installed a Santa Cruz sound card, and various ATI functions have stopped working acoustically. First, the packaged ATI File Player (for avi, dvx, mpeg) outputs video but no audio. And the TV-In-Demand function (records TV-out to the harddrive) also lacks sound play. But the regular TV viewer and the DVD Player play sound just fine, and playing the sound works when playing the same avi, mpg, files on WinDVD some of the time. Can anyone help? I'm not a real tech expert, so any help would be appreciated.
