My school district is slowly moving to hybrid bringing in more students. I am tasked with setting up classrooms so that teacher's can do video and audio presentations for students both in the school and students still doing distance learning.

Here are were I am limited. The school doesn't have the network infrastructure to accommodate having 2 computers in each classroom.

Every classroom has only one network jack that is already connected to an IP Phone. The IP phone is being used as a switch to connect to the existing computer giving it an internet connection.

I tried some testing and setup the existing desktop to extend to the smartboards so that the teachers can work through just one device. Teachers have no problem moving the Chrome tabs and windows to the smartboards for presentation.

However, the audio will need to play on both the teachers headset and their speakers in a way that doesn't cause feedback. Which is not possible.

I am now having audio output for Google Meets through speakers only and mic through their headset. Which they are not happy with.

Has anyone implemented a better solution for their own districts?
