MKV is a popular container format that can hold video, audio, subtitles, and picture tracks in one file. It is open and free without patent or license restrictions and is widely used to store multimedia content, such as movies and TV shows.
However, some MKV files may have no sound when played. This article explains the potential causes and provides 6 feasible solutions.
What Causes the Problem of MKV File No Sound
- Unsupported MKV Audio Codec
- Corrupted MKV File
- Outdated Audio Drivers
- Unsuitable Media Player
#Cause 1. Unsupported MKV Audio Codec
Audio in the MKV file can be encoded by various codecs, such as AAC, MP3, DTS, AC3, and FLAC. Generally, audio encoded by MP3 or AAC is compatible with most video players. However, if the MKV file uses a DTS (Digital Theatre System) audio codec, it can’t play in some video players.
#Cause 2. Corrupted MKV File
If the MKV file is damaged, it can also cause the MKV file no sound or even no video. MKV files downloaded from unauthorized sites or unverified sources can be easily corrupted. Furthermore, there are other factors that can make MKV files corrupted, including improper transfer, device crash, unreliable media player, memory card issues, or improper video conversion.
#Cause 3. Outdated Audio Drivers
Audio drivers play an important role in the quality and performance of the audio system. When you encounter a file with no sound issue, you can suspect that the sound driver is one of the causes of the problem. Because proper audio drivers can make your audio hardware work seamlessly with your operating system and software. There may be various audio problems, like no sound or malfunctioning audio features.
#Cause 4. Unsuitable Media Player
On the one hand, if the media player doesn’t support playing MKV files or MKV files encoded with DTS, you can’t play them successfully. On the other hand, if your media player is installed improperly or is outdated, it may also result in audio problems, such as no sound or audio fading.
