Hi, if you don't have to play simultaneously with students, Zoom or 
Jitsi (FLOSS) can do it. I use jitsi for online course and it works 
nicely, but with some latency, so no way to play with students. If you 
have to play with them, Jamulus can do it with good settings (no wifi, 
you must have 2 computers, one for jamulus 'server' - no need a real 
server, just the jamulus server app- and another for jamulus app). But 
students needs a computer and sound card, etc... Zoom (which have a 
Linux app) or Jitsi can be used on phone/tablet or computer, so more 
flexible but doesn't allow to play simultaneously without problematic
