.DTSHD file extension
To open .DTSHD files on Windows, check whether your current player supports DTS-HD: try opening the .DTSHD file from within the player (File → Open) instead of double-clicking.
To open a .DTSHD file, use a media player or tool that can decode DTS-HD audio streams. If your default player can’t open it, keep the extension as-is and try a different audio-capable app or convert it in a media tool that supports DTS/DTS-HD.

How to open .DTSHD files
Use these platform-specific instructions to open .DTSHD files safely.
Windows
- Check whether your current player supports DTS-HD: try opening the .DTSHD file from within the player (File → Open) instead of double-clicking.
- If it doesn’t play, try a different media player/decoder that explicitly supports DTS/DTS-HD audio streams, or remux/convert the track using an audio/video tool that can handle DTS-HD.
Mac
- Open the file from inside a media player that supports DTS/DTS-HD decoding rather than relying on the default app association.
- If playback fails, remux or convert the stream to a more widely supported container/codec using a tool that supports DTS-HD input.
Linux
- Try opening the .DTSHD file with an installed media player via your file manager’s “Open With” (the file may be identified as audio/vnd.dts.hd or an alias such as audio/x-dtshd).
- If no app is offered or playback fails, install a player/codec stack with DTS/DTS-HD support, or convert/remux the audio using a media tool that can read DTS-HD streams.
iOS
- iOS typically won’t play raw DTS-HD elementary streams in the Files app: transfer the file to a desktop media player/tool that supports DTS-HD, or convert/remux it into a more compatible format on a computer before syncing back.
Android
- Android support for raw DTS-HD streams varies by device and player: if it won’t open, move the file to a desktop system to decode/convert/remux it into a more compatible format.
Security notes
- .DTSHD is an audio stream and does not inherently include scripts or macros, but opening untrusted media can still be risky due to potential decoder/parser vulnerabilities—prefer well-maintained media software.
- Be cautious with “codec packs” or unofficial installers offered by random sites to add DTS-HD support; prefer reputable sources and standard package managers where possible.
- If a .DTSHD file arrives from an unknown source and triggers crashes in multiple players, treat it as suspicious and avoid repeated testing in sensitive environments.

Can't open this file?
These are the most common causes and fixes when .DTSHD files fail to open.
Common reasons
- The file won’t play or opens with an error
- No associated app (double-click does nothing or prompts to choose an app)
- You expected video but only got audio
- The file plays but you get silence or wrong channel layout
Fix steps
- Try a different media player or workflow tool that explicitly supports DTS/DTS-HD audio streams.
- If you only need playback, remux or convert the audio to a widely supported container/codec using a tool that accepts DTS-HD input.
OS-specific troubleshooting
What is a .DTSHD file?
.DTSHD is commonly used for a DTS-HD audio elementary stream, with the registered media type audio/vnd.dts.hd. DTS-HD (including DTS-HD Master Audio) is a high-definition surround audio format that can include a lossy “core” plus a lossless extension, depending on the stream. Because it’s an elementary stream, it may not contain video or a container structure like MKV/MP4, which can reduce app compatibility.
Background
The .DTSHD extension is used for DTS-HD audio elementary streams and maps to the IANA-registered media type audio/vnd.dts.hd. In practice, you’ll most often encounter DTS-HD audio as part of a movie disc workflow or a rip/transcode pipeline, where the DTS-HD track is extracted as its own stream file rather than stored inside a general-purpose container.
DTS-HD Master Audio is widely known as a lossless format that can carry high-fidelity multi-channel surround sound, and it is often discussed as an extension over a DTS “core” stream. Whether a given .DTSHD file is lossless DTS-HD MA or another DTS-HD profile depends on the content of the stream.
On desktop systems, file association is often handled via MIME type databases. On Linux desktops in particular, shared-mime-info includes DTS-HD-related entries and aliases (including audio/x-dtshd), which can affect how file managers label the file and which apps are suggested. Even with correct association, actual playback depends on whether the installed player/decoder supports DTS-HD.
Common MIME types: audio/vnd.dts.hd

Common .DTSHD issues
The file won’t play or opens with an error
Many default media players don’t include DTS-HD decoders, and some apps can’t handle DTS-HD as a standalone elementary stream.
- Try a different media player or workflow tool that explicitly supports DTS/DTS-HD audio streams.
- If you only need playback, remux or convert the audio to a widely supported container/codec using a tool that accepts DTS-HD input.
No associated app (double-click does nothing or prompts to choose an app)
Your system may not have a registered association for audio/vnd.dts.hd (or an alias like audio/x-dtshd), or no installed app claims it.
- Use “Open with” and select a media player that supports DTS/DTS-HD, then set it as the default for this extension if desired.
- On Linux, update shared MIME associations and install a compatible player/codec stack if the file manager doesn’t recognize the type.
You expected video but only got audio
.DTSHD is typically an audio elementary stream; video (if any) is stored separately or in a container file such as MKV/MP4 in other workflows.
- Verify whether you received only an audio track; look for a separate video file or a container file that includes the track.
- If you need a single playable file, remux the audio into a container alongside video using a tool that supports DTS-HD.
The file plays but you get silence or wrong channel layout
DTS-HD is commonly multi-channel; playback depends on correct decoder support and output configuration (downmixing, passthrough, HDMI/AVR settings).
- Check your player’s audio output settings (stereo downmix vs. multi-channel vs. bitstream/passthrough).
- Try another player/decoder path if your current setup can’t decode or output DTS-HD correctly.
FAQ
What does the .DTSHD extension mean?
It commonly indicates a DTS-HD audio elementary stream file format, associated with the media type audio/vnd.dts.hd.
Can I just rename .DTSHD to .DTS or .WAV to make it work?
No. Renaming only changes the filename extension and doesn’t convert the underlying audio data. Use a tool that can decode/convert or remux DTS-HD properly.
Why does my system call it audio/x-dtshd instead of audio/vnd.dts.hd?
Some MIME databases (notably on Linux desktops) use aliases for detection and compatibility; audio/x-dtshd is an alias used in shared-mime-info while the registered IANA type is audio/vnd.dts.hd.
Is DTS-HD Master Audio always lossless?
DTS-HD Master Audio is described as lossless, but “DTS-HD” more broadly can refer to profiles that may include a lossy core plus extensions. The exact properties depend on the specific stream.
