How to make videoconferences work on Linux with Chrome and Teams PWA?

Question

I'm using Fedora 40, which uses pipewire to manage audio services (instead of the legacy pulseaudio app), with Linux kernel 6.8 (using Intel SOF drivers). My company is now upgrading to Teams v2.

With such configuration combination, Teams PWA (Google Chrome) is not working anymore for videoconferences, as it is not detecting any audio input or output device, even being properly set (I'm enclosing some logs).

Wow can it be fixed to make teams work again?

Thanks,
Mauro

Answer 1

Does this issue persist all the time?

Yes.

Have you tried to change another browser to see if it works?

No. Teams on Firefox never worked properly. Also, at the corporation I work, everything is optimized to run on Google Chrome.
