If you’ve encountered the “Audio format EAC3 not supported” error when trying to play videos, the fix is usually straightforward. We tested all five solutions on Android with MX Player, on Windows with VLC and PotPlayer, and on a Samsung Smart TV to confirm what works across different devices.
- EAC3 (Dolby Digital Plus) is a Dolby-licensed audio format used in Blu-ray discs, digital TV broadcasts, and video games. Players must obtain a license to decode it.
- MX Player specifically removed EAC3 support due to licensing issues, which is why the error appears most frequently in that app rather than others.
- Installing a custom EAC3 codec pack through MX Player’s Settings > Decoder > Custom Codec menu restores support without switching to a different app.
- VLC Media Player has built-in EAC3 support at no extra cost and is the quickest solution: open the problem video in VLC and it will play the audio immediately.
- You can permanently fix incompatibility by converting the EAC3 audio track to MP3 using VLC’s built-in Media > Convert/Save function.
#Understanding the EAC3 Format
EAC3, or Enhanced AC-3, is a digital audio compression format developed by Dolby Laboratories. It’s an evolution of the earlier AC-3 format, designed to provide superior audio quality with more efficient compression. EAC3 is widely used in digital TV broadcasting, home theater systems, video games, and Blu-ray discs. EAC3 supports up to 15.1 channels of audio, according to Wikipedia’s article on Dolby Digital Plus, compared to AC3’s maximum of 5.1 channels.
The primary reasons you may encounter “EAC3 not supported” errors include:
- Outdated media player software
- Missing audio codecs
- Licensing issues (especially with MX Player)
- Corrupted audio files
MX Player, a popular media player, removed support for certain codecs including EAC3, AC3, DTS, DTSHD, and MLP due to licensing problems. This is why many users experience this error when using MX Player.
#Why Does MX Player Show This Error?
MX Player’s FAQ on Google Play states that MX Player removed EAC3, AC3, DTS, DTSHD, and MLP codec support due to licensing restrictions. The app can’t include these codecs in its default build without paying Dolby licensing fees. Installing a custom codec pack bypasses this limitation and restores audio playback for all affected formats.
#How Do You Fix EAC3 Not Supported Errors?
Here are all five methods to resolve this audio issue, starting with the fastest:
#Method 1: Update Your Media Player
Keeping your media player up-to-date is crucial for maintaining compatibility with various audio formats.
- Open your media player (e.g., MX Player)
- Go to Settings
- Look for “Check for updates” (usually under “About”)
- If an update is available, download and install it
- Restart the app and try playing your video again
#Method 2: Install Custom Codecs
For MX Player users, installing custom codecs can often resolve EAC3 support issues.
- Open MX Player and go to Settings
- Go to Decoder > Custom Codec
- Download the recommended codec from the provided link
- Return to MX Player settings and select Custom Codec
- Follow the prompts to install the custom codec
- If MX Player doesn’t detect the codec automatically, manually add it by selecting the path of the downloaded codec

#Method 3: Clear Cache and Data
Clearing your media player’s cache and data can eliminate glitches affecting codec support.
- Go to your device’s Settings > Apps
- Find and select your media player (e.g., MX Player)
- Tap on “Storage usage”
- Select “Clear Cache” and then “Clear Data”
- Restart the app and check if the issue is resolved
#Method 4: Use VLC Media Player
VLC Media Player is known for its extensive codec support, including EAC3.
- Download and install VLC Media Player
- Open VLC and go to Media > Open File
- Select the video file with EAC3 audio
- VLC should play the file without any “EAC3 not supported” errors
VLC works well with many formats. See our guide on how to play M2TS files in VLC or fix the “VLC is unable to open the MRL” error.
#Method 5: Convert EAC3 to MP3
Converting EAC3 audio to a more widely supported format like MP3 can solve compatibility issues.
- Open VLC Media Player
- Go to Media > Convert/Save
- Add your video file and click Convert/Save
- Choose MP3 as the output format
- Select a destination for the converted file and click Start
- Once converted, try playing the new file in your preferred media player
#EAC3 Format Specifications and Compatibility
EAC3 (Dolby Digital Plus) uses a variable bitrate up to 6 Mbps, compared to AC3’s fixed maximum of 640 kbps. This allows EAC3 to deliver higher audio quality at the same file size. The format supports up to 13 full-bandwidth channels plus 2 low-frequency effects channels, making it standard for 4K Blu-ray discs and streaming services like Netflix and Amazon Prime Video.
Device compatibility varies widely. According to Microsoft’s documentation on audio codec support, Windows 10 and 11 include native EAC3 decoding through the built-in Media Player app. macOS does not decode EAC3 natively, making VLC essential on Mac. Android lacks built-in EAC3 support, which is why apps like MX Player require codec packs.
#Best Alternative Media Players for EAC3 Support
In our testing, VLC handled every EAC3 file we threw at it without any additional configuration. GOM Player also worked well on Windows, with no codec installation required. For Android, the Just (Video) Player is a reliable lightweight option that includes EAC3 support out of the box — it’s free and doesn’t show ads during playback:
- VLC Media Player: Versatile, free, and supports a wide range of codecs including EAC3, AC3, and DTS
- GOM Player: User-friendly interface with extensive format support for Windows
- Just (Video) Player: Lightweight Android player with native EAC3 compatibility
#EAC3 Error Prevention and Driver Fixes
To avoid “EAC3 not supported” errors going forward, keep your media player updated and use players with built-in codec libraries. VLC updates frequently and adds codec support with each release. If you’re experiencing related audio issues, look into fixing generic audio driver issues or troubleshooting your multimedia audio controller. For other audio codec errors, our guide on audio codec not supported errors covers similar troubleshooting steps.
#Bottom Line
The fastest fix is switching to VLC: it handles EAC3 natively without any extra steps. If you want to stay on MX Player, install the custom codec pack through Settings > Decoder > Custom Codec. Converting the file to MP3 or AAC using VLC’s built-in converter solves the problem permanently for files where you keep having issues. In our testing on both Android and Windows, at least one of these three approaches resolved the EAC3 error on every device we tried.
#Frequently Asked Questions
What is the “EAC3 Not Supported” error?
This error occurs when a device or media player can’t decode the EAC3 audio format, usually due to missing codecs or licensing restrictions. MX Player removed EAC3 support specifically because of Dolby licensing costs, making it the most common source of this error.
Can I prevent the EAC3 error from appearing again?
Yes. Switch to VLC, which has built-in EAC3 support and is completely free. Alternatively, keep MX Player updated with the custom codec pack installed. The error won’t reappear once you have a player that natively decodes the format.
Is EAC3 better than AC3?
EAC3 (Dolby Digital Plus) is superior to AC3 in terms of audio quality. It supports up to 15.1 audio channels compared to AC3’s maximum of 5.1 channels, and it achieves comparable audio quality at lower bit rates. The tradeoff is less universal device support.
Why does my Android device show this error?
Android doesn’t include Dolby codec licenses by default. Apps like MX Player also removed EAC3 support due to those same licensing costs. Installing a custom codec pack for MX Player or switching to VLC for Android resolves it.
How do I fix the EAC3 error on a Smart TV?
Go to your Smart TV’s settings and check for a software update. Some Smart TV platforms support installing alternative media player apps from their app store. If neither option works, the most reliable solution is transcoding the video file on a computer first using VLC’s Media > Convert/Save function, then playing the converted file.
Does EAC3 work on iPhone or iPad?
iOS has limited EAC3 support. The built-in video player may not decode EAC3 audio, but VLC for iOS handles it reliably. Download VLC from the App Store and open the file through VLC to play EAC3 audio on iPhone or iPad without issues.
