Fairly granular I'd say, there's a bunch of customizations and workflows you could go through. I'm probably not your best resource for this though. Look here: https://macrodroid.com/. Source: over 2 years ago

I see many recommending Tasker. If you want an Android automation software, macrodroid is way easier and as powerful as Tasker. https://macrodroid.com/. Source: almost 3 years ago

I’ve kinda made it work by installing an application called MicMute that mutes the microphone with a hotkey, (something like CTRL + ALT + M) then using VIA to map that hotkey to a button on the keyboard. Source: about 1 year ago

Hello, I found this program: https://sourceforge.net/projects/micmute/. Source: almost 2 years ago

There's a free app on SF called mutemic. You can bind a keyboard key and have push to talk for your mic. Alternatively you can toggle it on or off as well. When you have the push to talk function you can toggle between always on or off by double tapping the keybind. It's a good compromise until we have the functionality in game. https://sourceforge.net/projects/micmute/. Source: about 2 years ago

I think the easiest fix I found right now is to download MicMute app (https://sourceforge.net/projects/micmute/) set it up to function like push to talk.. Then switch your voice activation to open in siege and you should be good. Source: over 2 years ago

But it's kinda hard to find the switch on the cord during gameplay. And the DAC is not that close to my keyboard. I think I would find a way to get a keyboard or mouse shortcut over those methods. MicMute is one app I found and might try if the in-game stuff doesn't work out. This might have bugs too. Source: almost 3 years ago
