Screen vs sound

[AudreyBa]

Hello

When recording on zoom, there is a difference between my lips on the screen and the sound coming out of my computer. It's a new computer, a performant one with windows 11 (video HD 720..) Could you guide me to find from where could be the issue to  settle it ? Thanks !

p.s. on my computer, video and sound (and my lips) it's alright and when I transfer my video on YouTube also.
