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...

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).

Hi ... on your LG Ultra Fine are you connecting the Mac to the monitor through Thunderbolt or some other medium? Trying to find what is common here as I suspect you and I are doing something that most people do not, so wondered if it might be the connection speed or cable technology we're using...

Thealbs Chiming in as well that I have the same problem, also started several weeks ago. LG UltraFine 27-inch display, connected to Mac Mini (M1, 2020) via thunderbolt / USB-C, Mac Teams version 1.5.00.27260. Problem only happens when audio comes from the LG monitor, not a problem on headphones or internal speaker.
