Since the 2.0 update, upon joining a MP mission (eden, dedicated or otherwise), VON is stuck on no matter what channel you are on (side, group, vehicle, direct, etc).
Upon pressing your PTT button to attempt to stop it, has no effect... it is constantly 'hot-mic-ing'. This happens to any player that joins a MP mission with their PTT button in Arma 3 bound to any key. It also happens whilst joining and not pressing any PTT button.
Whether TFAR mod is loaded or not makes no difference.
After some testing... In order to STOP the hot-mic, one needs to unbind ALL PTT binds within Arma 3 BEFORE joining a MP server, therefore rendering in-game communications useless (unless using external communications mod, eg TFAR or ACRE mod via TeamSpeak).
Upon further testing, it seems it may be related to a mod. Using pure vanilla (no mods loaded), vanilla infantry, binding PTT button and loading in to MP Eden, the VON initiates (turns on, then disappears), but there is no 'hot-mic-ing'. Will test further.
Upon further testing, I have found the cause of the issue with having VON stuck on (hot-mic) and being unable to turn it off. Please see the updated 'Steps To Reproduce'.
Using purely Arma 3 Vanilla (NO mods loaded), I can now replicate the issue 'Always'.
The only way that I have been able to temp-fix this issue is by setting "disableVoN = 1;" in my 'server.cfg' file to disable all 'vanilla' VON, and then use 'Task Force Arrowhead Radio' mod via TeamSpeak3 for communications.
Please replicate and report back findings.
