First case, I split audio and create sound file. There is no sound in the file I have create and the sound in the hold project disappear.
That explains why there is no sound, if you have not made any editing, you can just close the project without saving then just reload the video file again.
Second case, I don't spli audio but when I combine many clip together, sound can be listened by each clip. But when I choose whole project, sound disappear too.
It could be a codec issue, that is why providing the properties of the video will help us determine what really is going on. Just in case here are some of the codecs that you may want to install.
Windows Media Player: http://windows.microsoft.com/en-US/wind ... dia-player or just download the Windows Encoder at http://www.microsoft.com/expression/pro ... rview.aspx
Direct X: http://on-msn.com/aLrk0j (WinXP)
