This is only a problem with MS teams.
Under normal use teams will disconnect and reconnect USB devices over and over again. I know it's the usb devices as the computer gives the audible new USB device "bing bong" sound. Often teams will also show that new camera or mic is even present during this process. This most commonly occurs at the start of the call. But for more than 50% of calls this can occur upwards of every 30 seconds or less during a call. There are sometimes events where the usb device is known to teams yet does not operate. EG showing that the camera and/or mic is present but they do not operate.
Note: No other applications suffers from these issues. Teams is a chromium based application and yet all the other chromium applications do not have these issues.
I'm using fairly standard usb devices. Currently I'm using the Logitech Streaming Cam. A rather ubiquitous camera. But other devices suffer the same fate.
When making a test call there generally is never an issue. The number of participants in a meeting does seem to loosely correlate to an increased frequency. But it happens in 1:1 meetings a lot. I do mean A LOT.
Generally over time the overall experience of using teams on this laptop with exactly the same equipment is degrading. As new teams patches come out it generally is getting worse. It is now common to simply dial from a phone into a meeting just so I can talk without interruption. The migration from old teams to new teams only seemed to amplify the problems.
Now it should be noted again. These devices have no issues what so ever in any other application. No other application has pauses stutters or even the usb disconnect re-connect issues. If I were a betting man I would put the blame on how teams is reading and clearing the data buffering coming from the devices. As it fairly obvious that teams is somehow controlling this.
