Windows 10 Audio Controls Explained
Windows 10 audio is managed through a handful of tools that don't always feel connected: the tray volume icon, a dedicated Settings page called App volume and device preferences, and an older desktop mixer called sndvol.exe. Understanding how they relate makes it much easier to fix a muted app, switch outputs, or find per-app sliders without hunting through menus.
This hub page walks through each built-in tool and links out to focused guides on volume control, the mixer, sound settings, and per-app volume — plus where EarTrumpet can simplify things further.
The tray volume icon
Clicking the speaker icon in the Windows 10 taskbar notification area opens a small flyout with a single master volume slider and a list of available playback devices. It's fast for a quick mute or volume nudge, but it doesn't expose per-application controls — for that you need the panel below or the legacy mixer.
App volume and device preferences
Windows 10 keeps its modern per-app audio controls in Settings > System > Sound, under a link labeled App volume and device preferences. Here every app currently producing sound gets its own volume slider and its own output/input device dropdown, so you can send a game to your headset while keeping music on desktop speakers.
See windows-10-app-volume-control for a full walkthrough of this panel.
The legacy sndvol.exe mixer
Right-click the tray speaker icon and choose Open Volume mixer, or run sndvol.exe from the Run dialog (Win+R), to open the classic Windows Volume Mixer. It's been part of Windows since Vista and still works fine in Windows 10, showing vertical sliders for the system and each running app.
Details are covered on windows-10-volume-mixer.
Sound settings and devices
Beyond per-app volume, Settings > System > Sound is also where you pick your default playback and recording devices, manage device properties, and troubleshoot sound. Read windows-10-audio-settings for the full menu layout.
Where EarTrumpet fits
EarTrumpet replaces the tray flyout with a single popup that combines master volume, per-app sliders, and per-app output switching in one place, so you rarely need to open Settings or sndvol.exe at all. See eartrumpet-for-windows-10 and follow the setup steps in eartrumpet-windows-10-guide.
A few practical notes
Beyond the built-in tools, many people run into the same handful of questions repeatedly: why an app is missing from a mixer, why levels reset after a reboot, and which panel actually lets you change an app's output device rather than just its volume. The focused guides linked throughout this hub — covering the volume mixer, per-app volume control, and every volume setting location — walk through each of those scenarios in more detail than a general overview can.
Frequently asked questions
Does Windows 10 have a built-in per-app volume mixer?
Yes, two: the modern App volume and device preferences panel in Settings, and the older sndvol.exe desktop mixer.
Where is the volume mixer in Windows 10?
Right-click the taskbar speaker icon and choose Open Volume mixer, or open Settings > System > Sound > App volume and device preferences.
Is Windows 10 audio different from Windows 11?
The underlying audio engine is the same, but Windows 11 combines mixer functions into one redesigned panel while Windows 10 splits them across Settings and sndvol.exe.
Do I need third-party software for per-app volume in Windows 10?
No, it's built in, though apps like EarTrumpet make the controls faster to reach from the tray.
