Sound plays through the speakers when you wanted headphones. One app is far too quiet. The left side of your headset is louder than the right. A voice sounds tinny ever since you plugged in a new device. These problems all come from the same place: Windows’ audio output settings, which are spread across several screens that most people never see. Once you know where each one lives, adjusting them takes a few minutes.
Quick answer: In Windows 11, open Settings > System > Sound and choose your device under Output (“Choose where to play sound”). Set the volume with the slider. To fine-tune, select the device itself, where you’ll find audio enhancements, spatial audio, format, and, depending on your build, left/right balance. To adjust a single app, go to Sound > Advanced > Volume mixer. To switch devices fast, press Windows key + Ctrl + V.

How This Guide Was Checked
Audio menu names change between Windows 11 builds, and many tutorials still describe Windows 10 paths or older interfaces. This guide cross-checks several recent tutorials and manufacturer documentation. Where a setting depends on your Windows version or on your manufacturer’s own audio software (Realtek, Dolby, or a laptop brand’s sound utility), the text says so instead of presenting it as universal. If a screen doesn’t match yours, that’s most likely a version difference, not a mistake on your part.
Where Each Setting Lives
| I want to… | Where to go (Windows 11) |
|---|---|
| Choose speakers, headphones, or HDMI output | Settings > System > Sound > Output |
| Switch output in two clicks | Windows key + A (Quick Settings), then “Manage audio devices” |
| Change overall volume | Volume slider, keyboard keys, or Settings > System > Sound |
| Change one app’s volume | Sound > Advanced > Volume mixer |
| Balance left and right | Sound > Advanced > All sound devices, or device Properties > Levels tab |
| Fix a hollow or distorted sound | Device properties: audio enhancements and spatial audio |
| Switch to mono audio | Device properties, or Accessibility > Audio depending on your build |
| Choose the audio format (sample rate, bit depth) | Device properties > Format |
Step 1: Choose the Right Output Device
- Press Windows key + I to open Settings
- Select System, then Sound
- Under Output, in “Choose where to play sound,” select your speakers, headphones, or HDMI output
- Play a song or video to confirm
If the device isn’t listed, check the connection and see the troubleshooting section below. For Bluetooth headphones, pair them first under Settings > Bluetooth & devices > Devices > Add device.
The Quick Shortcut
Press Windows key + A to open Quick Settings, then select the icon next to the volume slider (“Manage audio devices”) to pick a device without opening Settings. Windows key + Ctrl + V jumps straight to the sound output page.
Step 2: Adjust Volume, From General to Specific
Overall volume. Use the slider in Settings > System > Sound, the taskbar icon, or your keyboard’s volume keys.
Per-app volume.
- Go to Settings > System > Sound > Advanced > Volume mixer
- Under Apps, drag each program’s slider
- Use the System sounds slider for Windows alerts
An app can also have its own output device. In the volume mixer, select the app and choose its output device. This lets you send a music player to your speakers and a video call to your headset at the same time.
Silence isn’t always a Windows problem. A headset’s volume wheel, a mute button on a speaker, or an app’s own internal volume slider can all keep sound at zero. Check those before digging deeper.
Step 3: Balance Left and Right
If one side plays louder than the other:
- Open Settings > System > Sound
- Under Advanced, select All sound devices
- Under Output devices, choose your device
- Adjust the Left channel and Right channel sliders. 100% is the default for both
Alternative method (works on Windows 10 and 11): press Windows key + R, type mmsys.cpl, and press Enter. On the Playback tab, select the device, select Properties, open the Levels tab, and select Balance.
Balance applies to the specific device you selected, not the whole PC, so set it separately for your speakers, your headphones, and any other output. If a headset stays lopsided no matter what you do, try it on another device. The fault may be in the hardware.
Step 4: Audio Enhancements, Spatial Audio, and Mono
Audio Enhancements
Effects such as bass boost, virtual surround, and loudness equalization can improve sound or make it worse, depending on your hardware. To turn them off:
- Go to Settings > System > Sound and select your device under Output
- Set Audio enhancements to Device default effects (or turn them off, depending on the option shown)
- For individual effects, open More sound settings, go to the Playback tab, select Properties, and open the Enhancements tab
If a voice sounds hollow, metallic, or muffled, switching everything off is the fastest test for whether an effect is to blame.
Spatial Audio
In the device properties, the Spatial audio setting lets you choose Windows Sonic for Headphones or leave it Off. It applies to the selected device only, not to the whole PC. Our guide on turning on spatial sound in Windows covers the full setup, including Dolby Atmos and DTS.
Mono Audio
Mono audio merges the left and right channels into one. It’s useful if you can only hear from one ear or share a single earbud. You’ll find it in the device properties, or under Accessibility > Audio, depending on your Windows build.
Step 5: Choose the Audio Format
In the device properties, the Format field sets the sample rate and bit depth. The default is right for most people. If you hear crackling, or an app refuses to play sound, try a different format and use the Test button to confirm. In the classic panel (mmsys.cpl), the same setting is on the Advanced tab.
If you’ve changed too much and want to start over, see our guide on resetting audio settings in Windows.
Bluetooth Headsets: Why Quality Drops During Calls
Many Bluetooth headsets drop to a lower-quality mode as soon as the microphone turns on, because the same connection has to carry your voice in both directions. On some Windows 11 PCs that support Bluetooth LE Audio, you can choose Mono or Stereo while the microphone is active by selecting the headset under Sound. Availability depends on both your PC and your headset. If it isn’t offered, a wired headset or a USB microphone avoids the trade-off.
Common Problems and How to Fix Them
The Output Device Doesn’t Appear
- Check the cable or power, and confirm the device is on
- Under Sound > Advanced > All sound devices, see whether it’s disabled, and re-enable it
- Run the troubleshooter: Sound > Advanced > Troubleshoot common sound problems > Output devices
- Update or reinstall the driver in Device Manager, under Audio inputs and outputs and Sound, video and game controllers. If Windows Update keeps changing the driver, see our guide on fixing Windows Update issues
No Sound Over HDMI or DisplayPort
Audio over a display cable runs through your graphics driver. Select the HDMI output under Sound > Output, then make sure your graphics driver is current. See our guide on updating NVIDIA drivers.
Sound Keeps Going to the Wrong Device
When several outputs are connected (speakers, a headset, an HDMI monitor), Windows can switch on its own. Set your preferred device under Output, disable the ones you never use, and check the app’s own output device in the volume mixer.
Bluetooth Headphones Connect but Sound Wrong
Remove the device in Bluetooth & devices, pair it again, and if the problem continues, see our guide on reinstalling your Bluetooth driver in Windows.
The Microphone Doesn’t Work
Output settings don’t control the microphone. Its permissions and device choice live elsewhere. See our guide on managing audio input devices in Windows.
Options Are Greyed Out on a Work PC
On a managed device, organization policies can lock some audio settings. Your IT administrator is the right contact.
Frequently Asked Questions
How do I choose the audio output device in Windows 11? Go to Settings > System > Sound and select your device under Output. You can also press Windows key + A to use Quick Settings.
How do I change the volume of just one app? Open Settings > System > Sound > Advanced > Volume mixer, then drag the slider for that app under Apps.
How do I send one app to a different output device? In the volume mixer, select the app and choose its output device. This lets you play music on speakers and a call on your headset at once.
Why is one side of my headphones louder than the other? Adjust the balance under Sound > Advanced > All sound devices, or in the device Properties on the Levels tab. If the imbalance follows the headset to another device, it’s probably a hardware fault.
Do audio enhancements actually improve sound? It depends on your hardware and your taste. If a voice sounds hollow or metallic, turn the enhancements off to see whether they’re the cause.
What does mono audio do? It combines the left and right channels into a single channel. It helps if you have hearing loss on one side or share one earbud.
Why does Bluetooth sound worse during calls? Many Bluetooth headsets switch to a lower-quality mode when the microphone is active. On supported devices, the LE Audio format option can help, and a wired headset avoids the issue entirely.
How do I put everything back to default? Use the reset option in the volume mixer, or restore defaults for a single device. Neither deletes any files.
