It works fine for me, Here is how it looks on the logitech G510
Screenshot is from it on my own teamspeak server (didn't want to have a screenshot showing the AOD TS server)
Anyway, when someone speaks, it will show the active speaker over the title of the server (above the channel name) (I would prefer it to instead replace the teamspeak3 logo with the active speaker though)
Does anyone know when there will be a proper ARM version of teamspeak server? (would love to run it on a raspberry pi 2.0 since it has a decent CPU and 1GB of RAM)
