Hi,

I'm wondering if anyone tried to use Microsoft Temas either web version
or desktop app... Web version does work but making audio/video call
isn't officialy suppported, so you need to spoof user-agent to make it
partially working - but from time to time MS change something and it
just stop working. In the past weeks I was able to make audio calls, now
it's not possible (neither Firefox nor Chrome)

I tested my webcam and mic on https://www.onlinemictest.com/ and it's
all working, so problematic is the web application from MS.

Desktop application - here are two options, one for Linux, one for
Windows. I tried to run the Linux version using linuxulator,
brandelf-ing all the binaries but with no success...

How do you think - are there any chances to make the desktop app working
in out FreeBSD desktops?--


Yesterday I tried to call my colleague via Microsoft Teams web-app 
(latest Firefox on CURRENT, spoofed User-Agent). Yes, there is no audio 
and video at all in both directions.


If I run desktop version with linux strace and it crashes. I think it 
because of unimplemented cgroups calls. Both Microsoft Teams and Skype 
are Electron applications, that tries to run chromium in isolated 
environment.

The Linux version is buggy. The microphone often doesn't work.

Wine seems to be 1 bug away from running the Windows version:
https://bugs.winehq.org/show_bug.cgi?id=48775
Since I am forced to use Teams, I might take a look at it soon.

I tried that too... and still trying to get it to work. Now I have a
problem with current emulators/wine-devel - amd64 version does not work
at all, emulators/i386-wine-devel does not support staging, which is
required to build runas.exe.
Building emulators/wine-devel from ports on i386 chroot (with staging
enabled) throws some errors which I can't cope with:

I even tried to copy runas.exe from some other wine binary build, but
I'm not sure it's the way to go - wine throws exception, which tells me
nothing :)

At work I use Teams on a daily basis and it's more and more pain in the
a** having problems with audio/video calls. Switching to other OS is the
last thing I'd like to do...

BTW Some of my coworkers use Linux and they don't have much problems
with desktop app, although it's quite cpu/memory hog.

Thank you, that should help me get started.

I have 14 years and 295 patches worth of development experience with Wine,
so hopefully I'll get further.
