Audio input devices, such as microphones, are essential for various activities on Windows and Mac systems, including voice calls, video conferencing, recording audio, and gaming. However, users often encounter issues with their microphones, ranging from no sound input to poor audio quality. Understanding and addressing these common microphone issues can significantly enhance the overall user experience and ensure seamless communication and audio recording capabilities. Here, we will explore troubleshooting steps for common microphone issues on both Windows and Mac platforms.
