If you right click in your bin and create a new Bars and Tone element, add that to a new timeline, does that file/sequence exhibit the same behavior on playback?

[Mauro5FC6]

thanks, yes it does the same thing, tried different settings of timelines, fps, resolutions, and codec but still doing it. 

[Jeff Bugbee · Accepted solution]

If this is happening in a new sequence with bars/tone, codec and resolution is likely not the problem here.

Some people have reported going into settings and setting Default Audio Input to None can resolve this. Can you check this out?

[Mauro5FC6]

Jeff! thanks yes, that works perfect! 

at least for now, i wonder why of this ? 

Many thanks to everyone !
