Solving the Issue with VLC DTS Decoder 'VLC DTS decoder'

If you're experiencing problems playing back DTS (Dolby TrueHD) audio through VLC media player, despite having all necessary codecs installed, follow these steps to troubleshoot and resolve the issue.

1. Ensure Proper Codec Installation

Firstly, verify that your system has a functional copy of libdts-9.0.x or higher installed. You can check this by opening a terminal/Command Prompt as an administrator and running:

```

dpkg -l | grep dts

where libdtds.dll

```

2. Update VLC Media Player to the Latest Version

Ensure that you're using the latest version of VLC media player, which should include all necessary codecs for DTS decoding. To update VLC on Linux-based systems:

1. Open a terminal and run:

```

sudo apt-get update && sudo apt-get upgrade

```

2. On Windows or macOS, navigate to 'Help' > 'Check Updates'.

3. Reconfigure Audio Output in VLC

Sometimes, the audio output settings within VLC might be causing problems with DTS playback:

1. Open VLC and go to 'Tools' > 'Preferences'.

2. In the Preferences window, switch to the 'Audio' tab.

3. Underneath 'Output device', select an HDMI or digital surround 5:1 (if available) option.

4. Reencode Your Media Files

If none of the above steps resolve your issue and you're playing back ripped Blu-ray discs (.mkv or .mp4), try reencoding them using a tool like FFmpeg:

```

ffmpeg -i input.mkv -c:a dts -b:v 5000k output.mkv

```

This command will transcode the DTS audio from your source file to an mkv container while maintaining its original quality.

5. Check Your AV Receiver Settings

Lastly, double-check that your AV receiver is set up correctly for passthrough mode with HDMI-ARC enabled:

1. Refer to your receiver's user manual for specific instructions.

2. Ensure the correct input (HDMI) and audio output settings are selected in both your TV/AV receiver and media player.

If you've followed all these steps and still encounter issues, consider seeking additional assistance from a professional audiovisual technician or VLC support forums for further guidance on resolving this problem with your particular setup.
