Check channel and binding
Select the intended voice channel, press the displayed bind and confirm the indicator changes.
TACTICAL GUIDE
How do you set up voice chat and push-to-talk?
Select the correct voice channel, bind and test push-to-talk in settings, then confirm teammates hear you—if proximity sounds robotic, use the dedicated robotic-voice fix rather than only remapping PTT.

QUICK ANSWER
Select the correct voice channel, bind and test push-to-talk in settings, then confirm teammates hear you—if proximity sounds robotic, use the dedicated robotic-voice fix rather than only remapping PTT.
CHOOSE YOUR CURRENT STATE
Branch by what the other player can hear
A missing channel, a missing microphone signal and distorted proximity audio are different problems.
Check input routing
Select the active microphone, remove competing device routes and retest with one teammate.
Use the symptom-specific fix
Do not keep remapping PTT when the channel connects but audio quality fails.
PROCEDURE
Follow these steps
Open audio/voice settings and identify proximity, squad, leadership and command channels (names: verify in current build).
Bind push-to-talk for the channels you use; avoid conflicting with movement or helicopter yaw binds on PC.
Set input device/mic level in both OS and game; exclude the wrong default device.
Test in the deployment area or with a squadmate before relying on it mid-fight.
If voice is distorted/robotic in proximity, follow /fixes/distorted-robotic-voice-chat/ (Patch 1.4 resolved prolonged robotic VOIP; minor edge cases continue being monitored).
On PS5 audio cut-outs, check /fixes/ps5-audio-cutting-out/ (Hotfix 1 path) separately from PTT setup.
COMMON PITFALLS
Avoid these mistakes
- Talking on the wrong channel and assuming "VOIP is broken."
- Treating robotic proximity as a simple PTT rebind.
- Inventing universal "best" mic dB numbers.
- Helicopter pilots binding yaw and PTT to the same mouse buttons without checking.
QUICK ANSWERS
Voice Chat & Push-to-Talk questions
How do I enable push-to-talk in Hell Let Loose: Vietnam?
Bind PTT in the game's voice/controls settings and verify the input device. Exact menu labels: verify in current build.
Why can I hear but not transmit?
Wrong channel, unbound PTT, muted mic, or OS device mismatch—test each. If audio is robotic rather than silent, see the robotic-voice fix page.
Is robotic proximity voice a PTT issue?
Not primarily. Prolonged robotic voice was resolved in Patch 1.4 in collaboration with Epic Games. See /fixes/distorted-robotic-voice-chat/ for remaining edge case details and troubleshooting.
Do console players use push-to-talk?
Console voice uses the platform's radio/channel controls—verify the on-screen prompts in your build rather than copying PC key names.
