Broadcasting your background noise to 50 other players in Hell Let Loose: Vietnam is the kind of mistake you only want to make once. The game's voice chat system works differently on controller versus keyboard, and if you don't know the toggle behavior, you can leave your mic open through an entire match without realizing it. Here's exactly how to fix that.
How do you turn off open mic on controller?
The controller voice system in Hell Let Loose: Vietnam works as a toggle, not a hold. Press the left bumper once to open your mic, and press it again to close it. That single button controls the entire broadcast state.
To confirm your mic is active, look at the bottom-left corner of the screen during a match. If your name appears there with three white lines beside it, you are transmitting. Press the left bumper once and that indicator disappears, confirming you are muted.

The toggle design means you can walk away from your PC or console with the mic still open. After any callout, verify the indicator is gone before stepping away or letting background audio bleed through.
How can you tell if your mic is muted?
The bottom-left HUD indicator is your only reliable check. Your name paired with the three white lines means the mic is live. No indicator means you are muted. There is no audio feedback or separate mute icon, so the corner of the screen is the place to look every time you're unsure.
If you've pressed the bumper and aren't sure whether the last tap opened or closed the mic, do not press it again blindly. Check the corner first. Pressing it without looking risks toggling back to active when you intended to stay muted.

How does push-to-talk work on PC?
PC players using a keyboard don't face the same toggle problem. Voice chat on PC only transmits while you hold the assigned key. Release it and the mic stops immediately. There's no lingering broadcast state to manage.
The default key assignments break down by channel:
Hold the key, speak, release. That's the full loop for keyboard users. You don't need to manually disable anything afterward.
Quick tips to avoid open-mic mistakes
- After every callout, glance at the bottom-left corner to confirm the indicator is gone.
- Avoid spam-pressing the left bumper. One deliberate tap is enough.
- PC keyboard users have the easier setup here since releasing the key handles everything automatically.
- If background noise is a concern, keep the mic closed by default and only toggle it open when you have something worth saying.
