How to Set Default Microphone in Ubuntu Linux
Setting a default microphone in Ubuntu Linux tells your computer which audio hardware to use for voice calls, video chats, and sound recordings. Ubuntu 22.04 LTS and newer releases manage this primary audio input directly through the main sound settings panel.
Selecting your main microphone stops the operating system from guessing when you plug in multiple sound devices like a USB webcam and a gaming headset. Picking the correct device keeps your voice clear and prevents audio dropouts in communication apps like Zoom or Discord.
Open System Settings and navigate to the Sound panel. Under the Input section, select your desired microphone from the list of available devices to set it as the default. The input level indicator will confirm your selection.
