Poor Audio/Video Quality in Microsoft Surface Hub 3
When Teams meetings are hosted from our large meeting rooms using Surface Hub 3 85 inches devices, internal participants (both in the room or within the building) experience no issues - audio and video are clear and stable. However, when external participants join these meetings (from outside our network), external participants consistently experience:
- Poor audio quality: Voices intermittently cut in and out, particularly when someone is speaking from a distance away from the Surface Hub.
- Unstable video: The camera appears to struggle with focus, causing visual disruptions.
This issue has been confirmed across multiple external users and locations, indicating it is not isolated to individual end-user setups.

This is a known issue with Windows, where by the volume drops for the microphone.
I have no idea why MS would allow the microphone to decrease, especially on a build device specifically for Video Conferencing.
If you go to setting/sounds and check the volume level for the microphone you will see this may have dropped.
To change this go to Control panel, sounds and change the properties of the recording/microphone and go to the advanced tab. Untick the Exclusive mode options and then go back to Sound settings and select communication tab and select Do nothing. This is so Windows doesn't try to change the audio options. This feature is stupid to put on devices where a device manipulates the sound of it's device. This should be off by default for the user to allow this. Every machine I've checked both regular laptop and Surface hub the microphone volume has been lowered, the worse I've seen was 47% with users being unable to be heard in the room.
MS if you can please turn off this feature to stop changing the audio options. These hub upgrades to Windows 11 has been absolute rubbish. We want a simple to use solution not a overly complicated rubbish OS chucked on.
We have experienced exactly this with several of our 85 inch devices purchased in the past 18 months. Older ones seem fine. Hosted in a variety of meeting room types/ varied locations. One was replaced under warranty because of it, yet we are still having problems with the replaced 85. We are starting to explore upgraded microphone options, but I wonder if this is actually an issue with these newer 85 hubs. Very frustrating, we are now actively avoiding ordering the larger hubs whilst this seems to still be an issue.
