Summary: Sound plays through the monitor instead of headphones, or the 3.5 mm jack is ignored? Fix default output, jack detection, and Realtek audio on Windows 11.
Recommended app: PC-Troubleshooter — https://www.mytechnician.tech/apps/windows-troubleshooter/ (Microsoft Store: https://apps.microsoft.com/detail/9N7RWKW8SP24?hl=en-us&cid=mytechnician-web). Optional; every step below uses built-in Windows tools.

## The Problem
You plugged in headphones but audio still blasts from speakers, or Windows shows **Speakers** when you want **Headphones (Realtek)**. Volume works—just through the wrong device. That is different from [no audio at all](https://www.mytechnician.tech/tips/fix-no-audio-windows-11/): here the stack is alive but routing is wrong, jack detection failed, or Bluetooth grabbed output.

> **Bluetooth headset pairs but wrong device?** [Bluetooth not working](https://www.mytechnician.tech/tips/fix-bluetooth-not-working-windows-11/) first, then pick the headset below.

## Quick Checks
1. Plug **fully** into the green 3.5 mm jack (headphone icon), not mic (pink) or line-in.
2. USB headsets: try a rear motherboard USB port, not a front header.
3. Unplug HDMI/display cables briefly—Windows often jumps audio to **monitor speakers**.

## The Fix: Step-by-Step

### Step 1: Pick the Right Output (Fastest Fix)
1. Click the **speaker** icon in the taskbar.
2. Click the **arrow** or device name above the slider.
3. Select **Headphones**, **Headset**, or your USB device—not **Speakers** or **Display Audio**.

Or: **Settings** → **System** → **Sound** → **Output** → choose the correct device.

### Step 2: Set Default Device in Classic Sound Panel
1. `Win + R` → `mmsys.cpl` → Enter.
2. **Playback** tab → right-click **Headphones** → **Set as Default Device**.
3. If you see **Communications** tab → **Do nothing** (Windows won't duck volume to the wrong device).

### Step 3: Enable Jack Detection (Realtek Laptops and Desktops)
Many Realtek drivers pop a dialog when you plug in—if you clicked "don't show again" and chose wrong:
1. Open **Realtek Audio Console** or **Realtek Audio Control** (search Start).
2. **Device advanced settings** (or **Connector settings**) → enable **Disable front panel jack detection** **Off** (wording varies—you want detection **on**).
3. Unplug headphones → wait 3 seconds → plug back in → choose **Headphones** when prompted.

No Realtek app? **Microsoft Store** → search **Realtek Audio Control** for UWP builds.

### Step 4: Disable Unused Playback Devices (Stops Auto-Switch)
1. `mmsys.cpl` → **Playback**.
2. Right-click empty area → **Show Disabled Devices**.
3. Disable **HDMI**, **Display Audio**, and duplicate **Speakers** entries you never use—leave one speaker + one headphone entry.

Windows stops "helpfully" routing Netflix to the TV you disconnected last week.

### Step 5: Reinstall Audio Driver (Jack Re-Enumeration)
1. **Device Manager** → **Sound, video and game controllers**.
2. Right-click **Realtek(R) Audio** (or your USB headset) → **Uninstall device** → check **Attempt to remove driver** if shown.
3. Reboot—Windows reinstalls; then install the latest **Realtek + chipset** pack from laptop/motherboard support, not a generic unknown package.

### Step 6: USB and Wireless Headsets
* **USB:** **Settings** → **Sound** → confirm the headset is **Default** and not **Disabled** in `mmsys.cpl`.
* **Wireless:** **Settings** → **Bluetooth & devices** → device → **Connect** → set as output in Sound. Some buds need **Headset** vs **Headphones** profile—pick the one with stereo music, not hands-free phone quality.

### Step 7: Front Panel vs Rear Jack (Desktop)
Front headphone headers are wired to the **HD_AUDIO** pins on the board—wrong BIOS front-panel mode breaks detection. Plug into **rear green** port to test; if rear works, front header wiring or BIOS **AC97/HD Audio** setting is wrong (check motherboard manual).

## Still Wrong Device After Updates?
1. [Create a restore point](https://www.mytechnician.tech/tips/create-system-restore-point-windows-11/) then roll back the audio driver.
2. Run **Playing Audio** troubleshooter: **Settings** → **System** → **Troubleshoot** → **Other troubleshooters**.

## When It Is Hardware
* Jack crackles when you wiggle the plug—worn front panel or loose solder.
* Only Bluetooth works, no 3.5 mm ever—broken codec or missing front-panel cable on DIY builds.
* [Microphone](https://www.mytechnician.tech/tips/fix-microphone-not-working-windows-11/) on the same combo jack needs a TRRS plug or split adapter—audio out can work while mic does not.
