I want to start by stating that we have already carried out several tests, in which 2 laptops and 2 xiaomi cell phones have been used.
I can attest that the problem is not hardware because with the Discord app the problem does not occur with any combination of devices
Why don’t we use discord and that’s it? because latency is high and we only need to communicate on the same LAN
Well, that said. The problem is that when we are connected to our lan server, if we have two devices connected, one of them hears everything that is played on the system, such as YouTube videos, its own voice and the voice of the other person.
As indicated above, we have done tests connecting different combinations of devices (2 pc, 2 android, 1 pc and 1 android, etc …)
Depending on the device combinations the “ECO” is heard on one device or another …
What we have been able to identify is that in the devices that the TS3 account of the first person is associated with, the “ECO” is not heard. It is only heard on devices that are associated with the account of the second person.
I can say that it is not a TS3 problem, because it also happened with a Mumble Doker server
As server data: OS: Unraid (Linux), Docker TS3
both accounts are TS3 server administrators
