Audio has become choppy, noticing delays every few seconds

We are using lib-jitsi-meet and custom UI. For the past few days (around a week now) we have been noticing the audio has become choppy, and we are noticing a delay in the audio every few seconds consistently irrespective of the the network status, even with very good network user is facing this issue. I have checked the packet loss it is 0% and the bitrate upload is almost 50% more than the download. Can you please help me out.

Has there been an update or a changing part in the past week?

No, we did not make any change.
