volume mixer

The volume mixer in Windows 10 and Windows 11 is a built-in tool that lets you control the volume level of individual apps independently from the system volume. It is commonly used to fix low or quiet sound, troubleshoot silent apps, and manage per-app audio output devices. Common issues addressed include one app being much louder than others, apps not producing sound while system sounds work, and muffled audio. Solutions often involve checking the volume mixer sliders, disabling audio enhancements, changing audio formats, and updating drivers. The volume mixer also allows you to assign different output devices to different apps, such as sending music to speakers while keeping a meeting on a headset.
