no sound on timeline

[#1]

I edit my video and everything was fine but in one moment when i drag the video (WITH A AUDIO) from the project to the timeline I can see only video. On the picture you can see that if I'm looking to my project window and look to my video it shows me that there is sound in the video, but after I drag to the timeline there is no audio, can you help me please to solve this problem.
