A Series S headset that's gone silent is rarely a dead headset. The fix depends entirely on which sound is missing — game audio, chat audio, or your mic — and those are three different settings. Sort out which one first, then go straight to it.
Triage: which sound is gone?
- No game sound at all → jack seating, the Headset audio setting, or stale controller firmware.
- Game sound fine, no chat → the chat-mixer slider is pinned to Game (this is the #1 cause).
- You hear fine but your mic is dead → the mic toggle, an inline mute, or a privacy setting.
Fix it
- Reseat the jack — properly. Pull the 3.5 mm plug out of the bottom of the controller and push it back in until it clicks. A half-seated plug gives intermittent or no sound, and on the Series S it can leave the chat-mixer slider greyed out. If that slider is greyed, push the plug in slowly until you hear a bit of static — that re-detects the headset and un-greys it.
- Fix the chat mixer. Press the Xbox button → Audio tab (the speaker icon in the guide). Find the chat mixer slider — if it's pushed all the way to Game, your chat audio is fully muted. Slide it back toward center. This tab also has headset volume, mic on/off, and mic monitoring for a quick check.
- Set headset audio correctly. Settings > General > Volume & audio output > Headset audio → set to Stereo Uncompressed, confirm Headset mic is on, and set mic monitoring above zero if you want to hear yourself. (Save Windows Sonic / Dolby Atmos for after audio works — they need a working headset first.)
- Update the controller firmware. Settings > Devices & accessories → pick the controller → Update. Connect it with a USB-C cable if it won't update wirelessly. Outdated controller firmware is a real, documented cause of a dead audio jack — and the step most people skip.
- Isolate the hardware. Try another headset on this controller, and this headset on another controller. That separates a bad jack from a bad headset before you buy anything.
If the mic specifically is dead in party chat
Game audio working but nobody can hear you in a party is almost always a privacy setting, not the jack: Settings > Account > Privacy & online safety > Xbox privacy > View details & customize > Communication & multiplayer → set "you can communicate with voice" to Everybody or Friends.
A couple of Series-S specifics
- There's no optical port on the Series S (or Series X), so ignore any "set optical output" advice — it doesn't apply. Console audio rides the HDMI link, so if you have no sound and no picture, you're looking at a Series S HDMI/black-screen problem, not the headset.
- The greyed chat-mixer glitch can come back after some system updates when the controller idles. It looks exactly like a broken headset, but it's a software quirk — reseat the plug (slowly, until static) to un-grey it rather than replacing the controller.
FAQ
I have game sound but no party chat — why? The chat-mixer slider (Xbox button → Audio) is pinned to Game. Move it back toward center.
The headset worked, then died after a console update. Update the controller firmware — that's a known cause of a dead audio jack after a system update. (Controller firmware also affects power behaviour, like a Series S that flashes and won't turn off.)
My mic doesn't work but I can hear the game. Check the privacy "communicate with voice" setting and any inline mute on the headset — the jack is fine.
Does the Series S have an optical output for my headset base? No. Use HDMI audio or USB for a wireless base; there's no optical port on the console.
