How to Troubleshoot No Sound in iTunes

Since iTunes relies entirely on audio content, it becomes useless if it loses the ability to play sound. If you have lost sound in your iTunes software, it may indicate a few common problems. Fortunately, you can resolve many of these problems on your own without the need for expensive repair, but you may need to troubleshoot a variety of possible sound problems in order to discover which is causing iTunes to remain muted.

Step

Check your main computer volume and the volume of your speakers.

Step

Check your iTunes volume. iTunes has a volume slider of its own, completely separate from your main system volume, that appears near the upper-left corner of your iTunes browser, just to the right of the "Play," "Forward" and "Back" buttons. Try sliding the meter to the right to raise the volume.

Step

Update iTunes. Visit the iTunes software page at Apple.com and download the latest version if yours is no longer current.

Step

Update the audio drivers on your PC. While this will not affect Mac users, Windows users may suffer audio problems if iTunes relies on outdated audio drivers. Also try updating any sound card drivers.

Step

Remove any third-party iTunes add-ons. Unauthorized plugins and other add-ons can negatively impact your functionality, so if you have added any of these features, try deleting them from the "iTunes Plug-Ins" folder.

Step

Windows users will find the folder here:

Step

C:\Documents and Settings\username\Application Data\Apple Computer\iTunes\iTunes Plug-ins

Step

Mac users will find it here: Users/username/Library/iTunes/iTunes Plug-ins
