I have a new development with sound in Premiere. There is no sound playing clips in scene bin, the monitor will not play sound, scrubbing in the timeline, also no sound. BUT if you go to the individual soundtrack (you can see the audio waveform) in the scene bin or timeline and double click to open it up in it's individual audio clip window, sound plays fine.

The sound also play in Windows media player etc, and other sound play.

Please help me....
Ta in advance, Melskius
