Audio lag for all calls

Problems with audio/video sync using Zoom. Details below.

Issue: Other users on the Zoom call see my video approximately one to three seconds before my associated sound is heard.
OS: Windows 10, all updates applied
Internet: Cox cable, 150 Mbps, wired connection
Measured Internet speed: 96 Mbps
Latency measured by Zoom: ~ 40 ms
Calls started using Chrome browser or Zoom app, same result.

Attempted workarounds:

  1. channel bonding has no effect.
  2. Attempted to use phone audio per instructions at When selecting “Join Audio” button as instructed, a “phone call” option is not shown. Same for browser and app.

The phone call option, if it worked, would only be a workaround. The proper solution is to get either the app or the browser Zoom session to work as advertised.

Zoom developer’s forum issue 12361 seems to describe a similar issue. It was closed by Zoom on May 15 without any indication of a solution.

Hi @compata,

Thanks for the post. Are you facing this issue with Zoom client app or Zoom SDK? If this issue is with the Zoom client app, then this is out of the scope of what this forum is for(This forum is for Marketplace Apps), and we have no insights into the issue with the Zoom client. Please provide feedback to or try to contact Zoom client support at and one of the Zoom experts will be happy to assist you.

Thank you.

Thanks, Carson. Unfortunately, Zoom does not offer support tickets at this time. I’ve also been unable to find an associated user group. Any other suggestions?

Further, as mentioned above, what appears to be the same issue has been discussed on this forum in message 12361. Perhaps someone can comment on the solution.
