Troubleshooting MKV Files with DTS Audio Tracks on LG CX TV

Troubleshooting MKV Files with DTS Audio Tracks for LG CX TV

LG CX TVs are known for their excellent picture quality and versatile features. However, some users have reported issues when playing MKV files with DTS audio tracks using the internal video player. This article aims to provide a detailed guide on how to troubleshoot this issue and enjoy your MKV files with DTS audio tracks on your LG CX TV.

Understanding MKV, DTS, and LG CX TV

MKV (Matroska) is a popular container format that can hold various video, audio, and subtitle tracks. DTS (Digital Theater Systems) is a high-quality audio format often used in movies and music. LG CX TVs support MKV files, but the internal video player may not recognize DTS audio tracks, resulting in no audio output.

Troubleshooting Steps

To troubleshoot this issue, you can try the following steps:

1. Update the TV firmware: LG regularly releases firmware updates that may include improvements and bug fixes. Check the LG website for the latest firmware version and follow the instructions to update your TV.
2. Convert DTS to another audio format: You can use a video converter tool to convert the DTS audio track to another format supported by LG CX TV, such as AC3 or AAC. There are many free and paid video converter tools available online, such as HandBrake, Freemake Video Converter, or Adobe Premiere Pro.
3. Use an external USB device: If the above steps do not work, you can try playing the MKV files with DTS audio tracks from an external USB device. Connect the USB device to the TV and use the USB playback feature. This method bypasses the internal video player and uses a different playback engine that may support DTS audio tracks.

Using an External USB Device

To use an external USB device to play MKV files with DTS audio tracks on your LG CX TV, follow these steps:

1. Format the USB device: Make sure the USB device is formatted to FAT32 or NTFS file system. LG CX TV supports these file systems for USB playback.
2. Copy the MKV files: Copy the MKV files with DTS audio tracks to the USB device. Make sure the file names do not contain any special characters or spaces.
3. Connect the USB device: Connect the USB device to the TV using the USB port. The TV should automatically detect the USB device and display the USB playback screen.
4. Select the MKV file: Use the arrow buttons on the remote control to navigate to the MKV file you want to play. Press the Enter button to start playing the file.
5. Check the audio output: After starting the playback, check the audio output. If the audio is still not working, try changing the audio output settings on the TV.

Code Block Example

Here is an example of how to convert DTS to AC3 using FFmpeg, a free and open-source video converter tool:

This command takes the input.mkv file as input, copies the video stream without re-encoding, and converts the audio stream to AC3. The output.mkv file contains the converted MKV file.
