Push to talk "not working" — here's the fix

You're not blind: there is no setting literally named "Push to Talk". Voice defaults to open/toggle transmission, and the binding you want is hiding under a different name.

The fix — confirmed still accurate at launch

  1. Open Settings → Controls.
  2. Find "Radio channel On/Off" — this is the voice transmit toggle. Rebind it to a comfortable key and use it as your PTT/mute switch. Community-confirmed in the "PUSH TO TALK" Steam thread ("the name is misleading, but it's there") — a player replying on launch day confirmed the setting is still at this exact location in the shipped build.
  3. Controller: default transmit is LB / left bumper (Xbox layout).
Launch-day bug: voice keys stop responding mid-session. Multiple players report the transmit bind working for the first match or two, then silently failing — no crash, mic just stops transmitting until you rejoin. One player: "worked for like 2 games and then just stopped... spent the last 2 hours trying to find a fix"; another: "sometimes it works but in toggle mode, not push to talk. And sometimes it doesnt." Reports cross two independent communities the same day — Steam ("In game voice chat keys not working") and Reddit (r/HellLetLooseVietnam, "Anyone else's voice chat not working?" / "voip not working? or a quiet bunch?"). If it happens to you, the community workaround is leaving and rejoining the server, or Options → Audio → VOIP Disconnect/Reconnect. Update: Team17's own Aug 12 known-issues blog officially confirms a related bug — proximity chat audio can sound distorted/robotic (already fixed in Squad/Leadership chat, still being worked on for proximity), and a squad losing its Squad Leader stops being heard in proximity chat entirely. That's a plausible official-side explanation for some of these reports; a fix is in progress with their VOIP partner. Full list on the voice chat page.

Why it feels broken

The HLL series routes voice by channel (local / unit / command radio), so the binding is named after the radio channel, not "push to talk". If your mic seems always-hot in proximity chat, check the voice activation/toggle mode in Audio settings too. The naming confusion made it through to launch unchanged — it was one of the loudest playtest complaints (17+ separate threads) and the shipped build didn't rename or relocate the setting.

Waiting on a fix and stuck without a mic? Fire missions still work if you can type the numbers — our mortar & artillery calculator turns two grid references into range, azimuth and elevation in one line, short enough to paste into chat.

Last verified Aug 14, 2026, ~04:30 UTC (launch day) — fix location re-confirmed by a same-day community reply; intermittent-failure bug documented from live Steam + Reddit reports, now with a plausible official-side cause from Team17's launch known-issues blog.
