In another thread, I posted:
Critical Error: No sound (Ubuntu 20.04 LTS)
In several Teams meetings, I log into the meeting and can see my conferee partners, but I can't get sound, or they can't get sound. A total fail. I'm doing this in Ubuntu. I make sure that my devices are all set properly, I go to the "Sound" app in Ubuntu and set the Sound settings correctly, to no avail. Today, we were able to use phones to connect for a one-on-one call but I've missed being able to participate in critical meetings.
There's a solution posted on the web that involves turning off the new meeting experience. That won't work: I don't have that option (I'm using the free version, installed with sudo apt install ./teams_1.3.00.30857_amd64.deb).
Given that Teams cannot reliably be used, my firm is avoiding any Teams meetings, advising clients "Teams doesn't appear to be reliable, can we switch to google-meet or Zoom?". But some firms are hard-coded for Teams, so I'd like to get this fixed.
The normal Microsoft advice to "Check to ensure your drivers are up to date, if they are, and the problem persists, reinstall Windows 10" is obviously not gonna work here...
Shyamal Debnath replied and asked some questions, and suggested that I cross post here. Also, suggested I use the tag linux-teams. Done. So here's my reply to Shyamal:
Shayamal, thanks for a constructive response. So I'm using Ubuntu, and my understanding is that the only reliable way to use Teams on Ubuntu is to use the browser-based solution. That is, IIRC I read somewhere that the Linux/Ubuntu app doesn't work. [NOTE: See thread in this forum "Can't join meetings as guest from Linux Teams app's newest version any longer"]. When I click on a meeting link to open up Teams, and use the Teams linux app, the meeting apparently isn't recognized. So I'm using the web-based solution.
Ubuntu's sound setup is neither as simple nor as reliable as Win 10. I have a Jabra Evolve 75 (BT, noise cancelling) and an Jabra Engage 75 (BT, DECT, no noise cancelling) and once I'm in the meeting and can see the other folks, apparently nothing I do gets either of those devices working. When I boot I open the Ubuntu "Sound" setting window and select Jabra 370 (mic and analog out, respectively) for sound. The Jabra 370 is the USB dongle that has the BT connection in it, and it works with my Evolve 75 headset (which has a mike).
When I open my free Teams, a popup windows opens asking if I want to open a program (xgd??.open - can't recall exactly) and after I do this the web dialog offers connection via the web interface (as I said, the app just doesn't work). The picture pops up fine. But nothing I do (changing settings in Ubuntu's "Sound", changing settings in MS Teams, restarting the application, ... nothing allows me to hear or fellow meeting attendees to hear me.
Other apps (including browser based solutions like YouTube, and other conferencing programs like Zoom, Google Meet, Skype, webex all seem to work fine). It's just that when I log into a teams meeting I have no confidence that it will be useable.
I'll cross-post as suggested. Once again thanks for something constructive.
