Context In some scenarios we have a bad system set up with loud speakers and sensitive microphones in both ends.

On one end it's an open microphone in an office room that is supposed to be useable for anyone in the room (so not possible to use push-to-talk on that end).
In the other end there is a laptop with loudspeakers, builtin microphone and sometimes long latency connections ( push-to-talk can be used on this end).

In these situations talking from the laptop (2) will result in a lot of echo and it's very difficult to communicate.

Describe the feature you have in mind Describe alternatives you've considered I have a few different ideas to solve this:

In the room (1):

1.A. Mute self when others are speaking 1.B. Change Audio in sensitivity when others are speaking

On the laptop (2):

2.A. Deafen self when talking (push-to-talk-and-deafen) 2.B. Mute others when talking (push-to-talk-and-mute-others)

I'm not sure which of these would be the best, but I'm leaning to 1A as the one that would solve my particular issue in the best way.

Research direction: Review the audio processing module in Mumble to understand how audio streams are handled. Implement a feature that automatically mutes the local microphone when remote speech is detected, or adds a push to talk and deafen mode to prevent echo.
