A lot of people have a ton of Blu-rays which are contained in the .mts format that fail to open and play on Windows Media Player. It is even weirder to see the image moving but no sound at all. Windows Media Player .mts no sound issue seems quite bothering to most people? Well, check this out and you won’t be disappointed.

Part 1: Why Windows Media Player Plays MTS Files with No Sound

Before we get started, let me answer a general answer to some users who don’t really understand .mts format. An MTS file is a video saved in the Advanced Video Coding High Definition (AVCHD) format. It is the standard video format used by many Sony and Panasonic HD camcorders. It is also used for storing high definition video on Blu-ray discs. Yes, most of your home videos captured in camcorders are contained in this type of format.

Windows Media Player is one of the most common media players in the world. It plays almost everything and it is handy to use even for beginners. However, when it comes to playing .mts files on Windows Media Player 11, you can hardly make it happen. Why?

Part of the reason for the failure of .mts playback on Windows Media Player is because this format is not supported natively but fortunately, Windows adds the support of .mts file format since Windows Media Player 12. It is said that it still shows no sound on some occasion during playback. This is because Windows Media Player lacks codec support to decode .mts in order to play the file smoothly and completely. You now have two options to remedy the no sound on Windows Media Player issue, first of which is to convert .mts to Windows Media Player compatible format and second is to install the codec again. Let me walk you through these two solutions one by one shot that you can fix the Windows Media Playerno sound issue successfully.
