The most common cause is outdated or incompatible audio drivers. Missing enhancements in the audio settings or hardware limitations with USB or 3.5mm jacks can also be an issue. Additionally, settings like “Allow applications to take exclusive control” may interfere with the boost option.
1. Run the Recording Audio Troubleshooter
Before trying anything else, run the Recording Audio troubleshooter to detect and fix issues like driver conflicts or incorrect settings. It can automatically identify why the microphone boost option is missing and apply fixes, saving time and effort.
2. Change the Port Used to Connect the Microphone
This issue can be caused by the type of port you’re using for the microphone. Some ports, especially USB connections or improperly configured 3.5mm jacks, may not fully support audio features like microphone boost. Changing to a port directly connected to the sound card (like a dedicated mic jack) may activate the boost option and resolve audio enhancement issues that weren’t available with the original connection. If you’re using a Realtek driver, you’ll get a prompt to identify the device that was plugged in. In this case, check the box for Mic In and hit Ok to save the changes.
3. Update All Windows & Sound Drivers
Some users have fixed this issue by updating all Windows and sound drivers. Outdated drivers can cause compatibility issues, preventing features like microphone boost from appearing. Updating ensures your system uses the latest software versions, which can restore missing options by resolving conflicts between your hardware and the operating system.
4. Buy a PCI Sound Card
Upgrading to a PCI sound card provides better audio control and can resolve missing microphone boost issues. Unlike built-in sound chips, these cards support advanced audio features and come with drivers that unlock options like microphone boost, improving input quality and volume.
How to Increase Microphone Volume in Windows
If your microphone is producing low or unclear audio, adjusting the volume in Windows can often fix the issue. By increasing the microphone level in the sound settings, you can improve input levels without needing the specific “boost” feature.
