Share system audio during meetings
During meetings we need to be able to share an online video with team members. Videos could be in Stream or Youtube or Vimeo or others. And this includes sharing the video sound. Currently we use normal Teams screen sharing, but all team members on the call can either hear or see, the video/audio are always asynchronous.

Thank you for your feedback. We’re happy to announce that Mac support for sharing system audio is now available to users who have opted into Public Preview.
Please see feature details here: https://techcommunity.microsoft.com/t5/microsoft-teams-public-preview/now-in-public-preview-channel-include-computer-sound-on-mac/m-p/2107853.
You can learn more about the new Microsoft Teams Public Preview program here: https://aka.ms/TeamsPublicPreview, and Teams administrators can find documentation to manage which users will see the Public Preview option here: https://aka.ms/TeamsPublicPreviewAdmin
Enjoy!

Please can you share the process to allow me to share computer audio in teams when using a MacBook Air. I have seen all the comments and right now nothing works. This is extremely frustrating as the "share computer audio" button does not exist.

We really need this option to be publicly available immediately. I had a situation occur today where I was forced to teach a class from home on my MacBook and I was unable to do so given that I can not change my administrator permissions with my district and I was unable to share system audio. It's highly concerning that almost a year into the pandemic and roughly eight months after the first thread addressing this issue was created, the software still has such glaring issues in it. I am very disappointed in Microsoft and upset that it is keeping me from doing my job.

UPDATE: First thing I discovered? This feature is only supported on certain Apple operating systems. According to MS, they only "support" the last 3 Apple OS - which would be BIG SUR, CATALINA, and MOJAVE. Since I run a large Apple lab I was able to test several systems. Sharing screen audio in TEAMS meeting does not work on High Sierra (4-systems old) and does not work on CATALINA (which is just 1 OS old). In fact with Catalina, I got the same "ran into a problem-give it another try" error message - and then it does not download the driver.
It works on MOJAVE - sort of. It will share YouTube audio and you can lower the video volume and continue instruction, and you can mute your mic without fear of losing the video audio. That's actually the expectation of this feature.
It does NOT share audio from DAWs such as Pro Tools - and I tried configuring my audio several different ways. I tried with and without my interface; I routed audio to default computer output, I even routed audio to the MS driver that downloaded. I could not share screen audio from Pro Tools out to my students at home during TEAMS meeting.
So far all I can get to function is YouTube. And - you'll need to share the entire desktop; choosing just the YouTube screen didn't work. I have not tested it with PP or other apps on my computer that may involve sound (I ran out of patience).
Ironically I had a meeting with a producer recently and he shared his audio from Pro Tools to all of my students without any issues, no problem - but we were in a ZOOM meeting!
So it's apparent that the feature we're asking for can actually be done. My guess is that that MS cannot figure out how ZOOM is making it work. So at this time I would say MS is not finished. Too bad they (MS) didn't actually read this blog with responses from actual users who are doing multiple TEAMS meetings with real students DAILY!

It now appears the "driver" is attempting to load, it gives me the message asking to do a one-time install of a driver (this is new). EVERYONE IN OUR COUNTY was working remote today due to weather, so this would have been great if it worked... However, I get error message when trying to the load driver:
"Couldn't install driver. WE ran into a problem. Give it another try."
HOPEFULLY this issue is ironed out soon, going to try it on other Macs tomorrow with different OS installed.

Can you please bring it into the app? I am not in the position to ask IT to modify admin settings..

For me, something goes wrong every time I try to share audio with both the “new” feature and the workaround when I try to use EXTERNAL HEADPHONES as my sole output. Both work well if I have the Built-In Speakers selected, either by themselves OR in a Multi-Output device including both the External Headphones and the Built-In Speakers.
On Teams, it works when I use the Built-In speakers OR the Multi-Out for the output settings. Any idea why I must include the Built-In speakers to make this work? I’ve included screenshots of everything mentioned. Thanks!

Come on Microsoft, what's up with this "phantom driver" that nobody has seen?? After all of the semi-fanfare - nobody can get this feature to actually work on a Mac.
And the best we get from MS is silence - no response at all. Great customer no-service.

Tested on two macs with latest Teams (1.3.00.33671 ) and latest Catalina OS (10.15.7) in Public Preview and Developer mode.
I now get the "Include computer sound" option, but the sound at the other end is clearly just the microphone looping back. If I mute the mic to stop any chatter, the sound of the video stops too.
Teams never asks to install a driver for the audio, and with the mic active, the sound is poor at the other end. -

Trialled this mornings Live Sound Class.
My admin had to enable Public Preview for my account, I had to enable it also through my Profile. Worked absolutely fine....but Teams only outputs in Mono.
Good luck teaching Stereo concepts

I get the option to share audio, but no driver install pops up - it still works though. I had to ask my IT support to enable Public Preview for me, then had to also enable via my Profile > About.
It seems to be working, but not if I use a headset - just having my output and input set to internal.

This feature keeps me from using Teams even though my organization pays for the whole ecosystem. At every opportunity I recommend switching to Zoom (less glitchy and faster).

I trialed Loopback (rogue ameoba) this morning a 15 minutes to see if I could bypass this problem. It did work, and then after the trial....white noise! It was expensive to but so I passed on it! However, just afterwards I saw a notification on my Teams app that there was an issue which needed to be fixed....it lead me to a download / upgrade of Teams.After restart of Teams ..... Good news .....my class this morning (post trial!) told me they can hear music from youtube, a powerpoint voiceover, a CD.....I'm sooooo afraid to restart the Mac now that its working!!!! What now???

Well, here we are again - so far nobody has reported anything positive. I've not talked to one Mac user at my school who got it to work today. Apparently none of the IT people in my county know anything about the "Public Preview Program" because when I ask about it they seem like they have no idea what I am talking about. So far the conclusion is that if you are NOT added by your TEAMS administrator to the Public Review Program, you will not get the driver to download.
MS - can you please just release the so-called driver so we can actually see if this new function will work?

Will this update be an "easy" update for users, for the admins to push a pkg with ARD? Zoom requires an admin password, each and "every" update it has...which gets annoying for admins, with 300+ Macs to deploy updates. Please say this won't be that way for us...thanks!

Yep, I'm experiencing the same thing, as are some of my colleagues who wanted to test this today (no audio driver is loading) - HOPEFULLY MS will be monitoring this and get the driver issue solved.
Just a hunch: It "might" have to do something with network admin having to turn the developer feature on from their side so we have full access. From MS website: "the option to turn on public preview is controlled in an admin policy." So while we toggle it on from our side and see the feature, "maybe" it must also be toggled on from the Admin side to the feature works - and we get the driver?" Seems more complicated than it needs to be...

I'm a teacher and Mac-user, I was waiting for this feature ... but it doesn't work!
I am in developer mode (public view) too, the button "share audio" appears but the driver-installation doesn't start. Happens on both of my Macs.
What's the problem ... ? -

Folks, it appears the "share screen audio" feature is "finally" out for Mac users (open the screen shot)! I am in developer mode (public view), but this should be released to everyone next week according to an email I received. I am online teaching audio production with over 100 students daily, working on both Windows and Apple OS. I did try testing this - and it did not work. The directions said a driver would load the first time - NO DRIVER LOADED.
Far too many novice Mac OS users who are never exposed to Windows machines (so they don't know what they are missing). and hence, they think they are sharing their screen audio in TEAMS meetings when in fact are simply looping their speaker audio back into their microphone (creating a feedback loop)... only to discover at some point that when they "mute the mic" - the folks in the meeting stop hearing the screen audio. FINGERS CROSSED MS FINISHES THIS JOB.

Are you trying to get Mac users switch to Windows devices or something? Because that is NOT gonna happen. Just release it already, everybody is hurting because of this!
Unbelievable...
