Unmuting the sound or increasing the sound volume often fixes the problem and restores your sound. Muted or very low sound is often a default sound setting in music or video playback software, and online video sites, like YouTube. Look for a speaker icon or sound settings in the software menu bar or status bar, and check if the sound is muted or turned down. Many software programs and games have settings for controlling sound output, and these settings can override the volume settings in Windows. If you don't hear any sound through your speakers when playing a song, video, game, or other sound-related activities, review the sections below for help on troubleshooting the issue.
