How can I completely disable the new voice chat?

Wit PTT option, it makes you bind a key (without allowing modifiers). This could conceivably conflict with any game.

Are you supposed to leave it set on "Open Microphone" and then set the threshold to "off" and hope it never broadcasts?

The chat window can still be set to not open when steam starts. Ironically you need to open the freinds chat window and select the gear (settings) icon. You can still set yorself to invisible and/or offline if you so desire. I also set my mic broadcast level to zero but this seems to reset when steam boots up.

Push to talk means, that you transmit while pushing that button while being in a voice session.

Like a walkie talkie. At least that is what should happen.

Using new Steam UI, as you know Voice settings are moved to Friends/Chat window unlike main settings menu. And its default setting is "Open Microphone" which may conflict with some games' in-game settings in which default setting was set to Push To Talk like Left 4 Dead 2. Isn't it a conflict?

For example in L4D2 settings PTT is enabled but Steam setting is set to "Open Microphone". What mode will it use to transmit voice?

I hope they will remove it from Friends > Right click. I miss clicked soo many times...
