The team has updated the default sound for Teams notifications so it is more noticeable. We are in final testing, with a goal to release the new sound by the end of this quarter.

Same here on Linux 1.3.00.30857 (64-bit).
I can see the playback channel is opening but no volume at all.
Even on Settings->Calls Ringtones selecting a ringtone the same issue.
That is quite annoying.
