Audio syncronazation

Hello everyone. l am newbie on editing. l have edited a long movie for my showreel. l lost video and audio synchronization. l dont want to start to zero. ls there any way to find audio for each video chunks?

The audio is still in the timeline, just out of sync?

Some of them are on the timeline but as asyncron, some of them are cleaned now.

Got it.

But...what does "cleaned now" mean?

l mean, that clips removed, deleted. Also, you can think that l deleted all audio's belong video's. But video clips was cut and edited into various chunks so thats timecode changed. l need synchronic audio's belong each chunk of videos.
