I found a bug on your Teamspeak 5 client.
If you have activated Push to Talk and a hotkey has been set you can’t talk anymore if you mute and unmute the 5 times in a row and then log in to TS 3 only once.
Can you confirm your current client version, what is your sound input device, what is your operating system, what do you mean log into TS3 while discussing TS5 and does the TS5 window have focus while testing?
For me this description describes that the user is in flood protection and is still muted on server.
First time -> mute
Second time -> unmute
Third time -> mute
Fourth time -> unmute
Fifth time ->mute -> flood triggers here
Sixt time -> unmute won’ t trigger on server.
Join server with Ts3 and increase flood prevention.
I can not reproduce this with 5 mute/unmute actions in Beta21.
I tried to reproduce this and the only thing i found was that i could not unmute again after i was added in flood. Yea that’s also an issue we have to fix.
