Zoom and Windows 11

With the latest version installed, I am told that my machine does not support virtual backgrounds. The help page does not list W11 among supported operating systems! Will that be corrected on the W11 release date?

      The changes made by the ISP seem to have worked. No more dropouts deep enough to cause trouble.

      So now I have my backgrounds and can Zoom happily.

      Cheers

      I just bought a new computer with Windows 11. I do online trainings. Since switching to my new computer I am having problems with zoom. After 30 minutes, voices become chopping. I can't hear my participants. I keep upgrading and that doesn't do anything. Zoom support tell me I need to upgrade and pay at least $50. a month to even get chat support. They said submit a ticket. I did and and received an email that they can't respond at this time and to look through links. So disappointing. I have Teams and going to check that out.

      It may be due to W11 using more memory.  Open Zoom-Settings-Statistics and check what is the memory utilization according to Zoom.  If your Overall utilization is too high, try closing your browsers (and anything else using lots of RAM) and see if that helps.   I assume you have enough bandwidth, but closing the browsers would help with that too.

      My Zoom sessions are also interrupted by bursts of gargling.  But I believe that someone on my internet fibre is paying more for bandwidth than I am.  

      Run Resource Monitor to see dips in bandwidth almost to zero. This is followed by a burst of activity as Zoom tries to catch up.

      When advising Zoom users with similar problems, I suggest closing all browsers and using Ethernet rather than WiFi; if WiFi is the only option, make sure that nobody else is using the same WiFi server (that is, other laptops and phones), set all phones to use cellular data instead of WiFi.  But often the problem is not bandwidth but memory availability in the same device.  Closing the browsers helps with that too.

      A helpful suggestion, but not the answer.  This occurs when I am the only active user on that router.  The same bandwidth dips occur away from Zoom, when I am uploading a video recording.  I have FTTH, but of course there will be a shared fibre or process in the system that serves a multitude of clients, one of which might be hogging all the bandwidth in bursts.

      My suggestion would be to take screenshots of Resource Monitor during the call, and to give your ISP a hard time.

      Cheers

      Hmmm, I am not sure a dip in the network utilization indicates a bandwidth problem.  Fiber is not shared, the way cable is.  If your network utilization drops it may also indicate that you are running out of another resource, and you are not ready to use the available bandwidth.  I would check your memory and CPU usage at the same points in which you see a drop in network traffic.

      The dips are reak enough, and occur on file uploads as well.  But the ISP tells me that they have made some changes at their end, so I will see.

      Missing frames in the linear prediction encoded voice data causes the gargling.  Could the data not be buffered, so that there is a second or two of silence, followed by a catch-up at 1.5 times speed?

      Cheers

      The forum layout is so badly organised that I cannot find the post that I am trying to reply to.

      Maybe there is a setting to show posts in chronological order, but it is far from obvious.

      Still 'reply' is being shown instead of 'post to forum'.

      Since backgrounds are now working, maybe I should unsubscribe. But there is still the issue of garbled speech during bandwidth dropouts. 

      Since it is possible to understand speech when played at 1.5 times, maybe a dropout should cause a pause, followed by the buffered content to be played at 1.5 speed to catch up.

      Cheers

      The dropouts due to bandwidth problems may be in the participant streaming out or in that receiving the stream.  Also, buffering and requesting a resend will cause a huge audio-video sync problem.  I am not sure what I detest more, garbled sound or lack of sync.  I guess it depends on the contents; for a conference garbled sound is the more serious problem, for music streaming bad sync is much worse.

      Glad you found your backgrounds. Zoom quality is way down with Windows 11. I give trainings via Zoom for a living. About 30 minutes in voices become choppy--they come in and out so I can't make out what participants are saying. My trainings are interactive. I attended a workshop yesterday. Same thing happened. What's frustrating is you can't chat with a zoom person unless you pay $50. a month or more. I am already paying. You can't talk to someone or use the live chat feature. You can only submit a ticket. 

       

      Awful!!!
