Static noise on MS Teams during powerpoint screenshare (Mac)
Hi, I've used Teams for a few years and this is a new problem for me in the last 2 weeks.
In Teams, if someone else shares their screen with a Powerpoint, I have very loud static noise so that I can't hear anything else and they can't hear me. I have to read captions/use chat. The noise stops as soon as they stop screen sharing.
It's only when they share Powerpoint. If the same person, in the same meeting, same set up, swaps to sharing a PDF of that Powerpoint there's no problem.
This has happened several times now - different meetings, different participants, different days, same problem. I've restarted etc. I updated to Monterey (12.6) after it started, but that didn't solve it.
Any suggestions on what I should try next?
UPDATED:
In one case, it seems to happen when they share their powerpoint by selecting from the 'powerpoint live' list - it doesn't happen if they share by selecting the 'window'.
- I somewhat fixed it by :
- deinstalling Teams : https://answers.microsoft.com/en-us/msteams/forum/all/how-to-completely-remove-teams-from-mac/2499239d-d491-43cb-a9c1-acbee7223b8d
- I also un-installed the teams Audio in /Library/Audio/Plug-Ins/HAL (not sure if this makes a difference)
- Installing an older version (NOT ticking on "installing the audio driver"): https://microsoft-teams-for-mac.en.uptodown.com/mac/download/75962667
- Preventing automatic autoupdate of microsoft programs (no way to prevent the automatic update of Teams only)
Not the best solution but at least one can interact with others... I am experiencing the same effect but slightly different scenario - and it started happening two weeks ago also.
I get this loud static noise when I share a PPT via Teams. I can't hear anyone else and - strangely - nobody else can hear the status even though it is deafening on my side. This is where *I* share the ppt slideshow, and does not happen when others share theirs with me.
I have a MacBook Air running the latest version of MS Teams for MacOS and use an Apple Studio Display.
I have tried all sorts of options but can't work out how to stop it.
I have now isolated these issues to the use of the Studio Display when sharing Powerpoint slides to an audience. It is only that combination that gives the issues and it fails consistently.
If I change the MS Team device settings to use the internal MacBook Speakers and Microphone then it works fine. As soon as I send them to the Studio Display it provides an incessant, loud, static noise to me... but no-one else can hear it.
Will try and report to Apple.
Same issue here not linked to studio display but a LG ultra fine display. It happens indeed when others share their screen using the powerpoint live function while we use external display audio : very loud static that none one else can hear. Switching to the internal speakers/microphone fix it but going back to external display audio during the same call show the same symptoms. One needs to leave teams or at least close the call and join again.
Interestingly, the static stops when the person stops sharing using powerpoint live.
This is very annoying and the latest Teams builds do not help (I just experienced the issue with the 1.5.00.27968 build).
extra info : -using an Apple M1 Max MacBook Pro on OSX 12.6 + LG ultra fine 5K (firmware up to date), all office apps up to date.
extra info on the setup of the one sharing using powerpoint live : Apple M1 Max MacBook Pro or PCs on Windows 10 (all up to date).

Just wanted to chime in and say we are also experiencing this problem with our Mac users (Mac OS 12.6, both Intel and M1 chips) on Teams Version 1.5.00.26358. Static audio for certain mac users, and the powerpoint slides turn purple/magenta for many Windows users on the call. It just started happening about 2 weeks ago for one mac user who presents a lot on calls -- his audio gets a loud static noise, and then the Windows users see magenta slides (inverted color?) instead of white background slides. It does seem to be specific to Powerpoint Live sharing, and LG UltraFine displays. Our org is currently trying to test whether it's specific to the audio of the LG Ultrafine Displays, or video, or both.
- I have the same issue (when used with the LG 5K monitor). Currently I have not found a fix. This was the case using Monterey as well as Ventura (which I just upgraded to.) Microsoft Powerpoint Live does not work because of the amount of STATIC NOISE.
Microsoft - please come up with a fix. Thanks.I'm having the exact same issue with a Mac Studio Display as well.
You have Microsoft Teams Version 1.5.00.28558. It was last updated on 10/29/22.
I'm having the same exact issue. Only way to solve for it is to plug some headphones directly into my laptop and switch my audio output to "External Microphones".
More broadly, Microsoft Teams does audio on the Mac in such a strange and unique way. None of the other video-conference tools I use have anywhere near the same number of issues. It's gotten so bad that I'm now actively asking coworkers and customers to use Zoom or Webex instead.
- I always use headphones and external mic - and that static noise is loud.
I've taken to asking people not to use powerpoint live - and if I'm in a situation where that's not an option, I take off my headphones and use live captions to try to follow their presentation until they switch the powerpoint off.
It is so annoying. Will Microsoft ever fix it?- Can someone else test this - I'm just in a meeting with the usual issue - someone's sharing on powerpoint live and I get the noise. Put the live captions on etc.
While they're still talking -
I pulled out the connection to my external monitor - noise still there.
I plugged the connection to my monitor back in - and the noise has gone!!
Game changer (for me) if this is repeatable.
Also experiencing this. MacBook Pro (16-inch, 2019), OS 12.6.1, Teams 1.5.00.31156.
Only happens when I (or another meeting attendee) use PowerPoint Live.
I did some experimenting by changing audio settings on my Mac (not in Teams), toggling from my MacBook, my Studio Display, and "Microsoft Teams Audio Device".
At one point I was able to get the sound from my Studio Display without static after randomly choosing different output sources, but don't recall exact sequence that worked.
- Same issue here on two MacBook 16's with LG monitor. We have to switch to the MacBook speaker during Powerpoint Live sessions.
why2022 I was able to fix this by removing the Teams Audio Driver:
Goto
/library/audio/plug-ins/Hal
delete the "msteamsaudiodevice.driver" folder
restartUnfortunately that folder not appear to exist on M1 Macs
Just writing on the off chance that anyone has managed to find a fix for this yet? It is still plaguing me and, as I keep my MBP in clamshell mode most of the time, is major friction to juggle things around when I decide I need to share some slides mid-meeting. Otherwise, I would have left the audio using there MBP audio permanently but the microphone doesn't work in clamshell.
I have the exact same problem when presenting PowerPoint Live in MS Teams on Mac. I have the latest Teams version app (1.6.00.4464) and the latest audio drivers. Why isn't there anyone at Microsoft addressing this issue that a lot of people seem to have?
