sound (audio) makes noise only in timeline

Questions & Answers
1

I have a background music which has no noise in original file.
When I play the music just using AudioSource (which means ‘not in timeline’), it doesn’t make any noise.
But when I play the music on timeline (using Audio Track), it makes noise a lot.
I have muted all the other tracks but it still makes noise.

When I say ‘noise’, I mean some sounds like short cracked sound.

(I have tested it on Unity 2017 and 2018)

Same problem here.
Unity 2018.2.5f1 (Win)
A sound played in the timeline had stutters.
Moved it out the timeline just to test it and the problem was gone.

I would suggest to file a bug. It doesn’t sound familiar and we would be interested in looking at a repro case.
