How to Change the Audio Output Format in Windows

Before you start

You can change the audio output format directly in Windows settings. This is a local system setting, so no online account or extra service is required. Make sure the playback device you want to configure is connected and recognized by Windows. Close any app that is currently playing audio or using a microphone if you want the new format to take effect immediately, because some programs keep using the previous device settings until they are restarted.

Step-by-step instructions

• Open the Start menu and select Settings, then go to System and Sound.
• Select the output device you want to adjust from the list at the top.
• Click Device properties or Properties for that output device.
• Under Output settings, open the Format dropdown.
• Choose a sample rate and bit depth from the available options for that device.
• Close Settings and restart the audio app you were using if necessary.

The exact wording of these options can differ between Windows versions. In newer versions, the format setting is usually shown under Device properties. In some older builds, you may need to open Sound Control Panel, select the playback device, open its Properties, and use the Advanced tab instead. The listed formats depend on the driver and the connected output device, not on Windows alone.

Keep the change reversible by noting the original format before you switch. If the new setting causes no sound or a distorted signal, return to the same dropdown and select the previous value.

Check the output

Play a familiar recording through the selected output device and listen for missing audio, clicks, or unusual distortion. You can also open the same device properties page again and confirm that the new format is still shown. If an app was already running, close and reopen it so it can apply the updated device format.

A higher sample rate or bit depth can be accepted by the system while the connected hardware still performs its own conversion. That means the selected option does not guarantee a measurable quality improvement, especially if the original content or the connected speaker or headphone hardware does not support the format natively.

Common problems and next steps

If no sound appears after changing the format, first switch back to the previous setting. Then check that the correct output device is still selected and that the volume is not muted. Restart the audio app and, if the problem continues, restart the computer so Windows can reload the audio driver cleanly.

If the expected format is not listed, the current driver may not expose it for the connected output device. Check for an updated audio driver through Windows Update or the device manufacturer's support channel, then return to the format dropdown. In some cases, an external audio interface or USB device offers additional format controls in its own app rather than in Windows.

Format problems can also appear during video calls or recordings when the input device and output device use very different settings. Background noise is not caused by the output format itself, but a badly matched rate can make capture and playback issues more noticeable. If the microphone sounds noisy or quiet, check the input device separately, reset its input level, and keep both devices on settings the hardware supports.
