How to Change Audio Track In Dual Audio Movies On Android (VLC, MX & Samsung)

---

I was feeling nostalgic this weekend for those classic Hollywood movies—the ones where incredible background scores and iconic sound effects mattered more than CGI.

I fired up an old favorite on my Samsung phone, but because it was a dual-audio movie, I immediately hit a wall: the default player made it surprisingly hard to change the audio track.

After a bit of trial and error (and some frustration), I finally got it working. The 5.1 channel Dolby Digital sound added a depth that was impressive even on basic earphones. While Android downmixes 5.1 audio for stereo output, features like Dolby Atmos or Spatial Audio can use multichannel audio to simulate a 3D soundstage—depending on your device’s audio processing. A player like VLC helps ensure proper decoding of the audio tracks, though the final spatial effect is handled at the system level.

If you're having trouble switching languages on your device, I've got you covered. Here is exactly how to change the audio track in dual-audio movies on Android using the native player, VLC, and MX Player.

What is a Dual-Audio Movie File?

A dual-audio movie file basically has more than one audio track built into a single video file. These tracks can include different languages such as English, Hindi, or Spanish. Most dual-audio files use the MKV format, which supports multiple audio streams and subtitles.

How to Change Audio Track Using Android Built-in Video Player

Here's a step-by-step guide on switching the audio language in dual-audio movies on Android. I am using a Samsung phone that uses the Samsung video player app. The Samsung video player app easily recognizes multiple audio streams (if encoded) in a movie file. Check the step-by-step guide below.

Note that I'm using a 5GB Blu-ray MKV (.mkv) movie file to test this tutorial on a Samsung Galaxy phone.

1. Make sure to copy the movie file on your Samsung phone. If you're using a Blu-ray quality movie then it may either have a .mp4 or .mkv format and file size may range up to 5GB. So, make sure your phone has enough storage space.
2. After copying the movie file to your phone, open the Samsung Gallery app and tap the movie file once to start playing it.
3. Now tap the three vertical dots in the top right corner and then tap 'Open in Video player.' Samsung Video Player opens up and starts playing the movie. Do not skip this—if you just watch it in the Gallery preview, the audio settings won't show up.

4. This is what the Samsung Video Player interface looks like—pretty straightforward once you’re in.

5. Now tap the 'three vertical dots' in the top right corner again and select the 'Language' option.
6. You'll see multiple audio streams to select from right on your screen. A movie can have multiple dubbed audio streams such as German, French, Spanish, and Japanese. Tap the audio language to select, the movie will immediately switch to your selected language.

7. You can now enjoy the movie in your preferred language.

If you're using a non-Samsung phone such as OnePlus, Google Pixel, Motorola, or Xiaomi then you can check if their built-in video players support this language switch feature. If the feature is missing then you can simply switch to VLC media player.

If your phone’s built-in player doesn’t support audio switching, you can use third-party apps like VLC.

How to Switch Audio Language in VLC Media Player (Android)

VLC is an advanced media player for Android that supports almost every video format. The good news about VLC media player is that it is totally free. Here's how to change audio track in dual-audio or multi-audio movies in VLC media player for Android.

1. Download and install VLC media player for Android from Google Play Store.
2. Open the app, grant file storage permissions and start playing your movie.
3. You'll see an interface like this below. Take a few seconds to check on its video player controls.

4. Tap the 'Audio & Subtitles' button in the VLC player controls. Under 'Audio' tap the desired language for your movie and then tap the 'back' button to return to the VLC player.

5. Rotate the screen to landscape mode to watch the movie in full screen. You can simply hold your phone in landscape mode, and VLC media player zoom will automatically adjust the video to 16:9 full screen.

How to Switch Audio Language in MX Player (Android)

MX Player is quite popular as an OTT platform. You can also use it to play your favorite movies but it is not as versatile as VLC as its interface is quite bulky.

MX Player offers useful features, but its interface may feel heavier compared to VLC Media Player for some users.

1. Open the desired movie file in MX Player and switch to landscape mode (full screen) by rotating your phone's screen.
2. Tap the 'Audio/Music Note' button to open the language options. This button is not visible in portrait mode, so, to access it, tap the 'three vertical dots' menu button in the top right corner and tap 'Audio language' option.

3. Once you tap the button, you'll see the list of audio streams your movie is encoded with. Tap the desired language to switch.

Use Network Stream to Watch Movies If Your Phone's Storage Is Low

You won't be able to transfer large movie files to your phone if its storage is nearly full. So, let's assume if you have some 50 movies and wish to watch them whenever you like.

It is not practical to transfer all those movies to your phone due to limited storage. 50 movies may total around 200-400GB or more in overall file size. Android phones typically do not have that much storage.

So, what's the best way to watch movies on your phone without transferring them every time?

For this, you can use Samsung's Network Storage Manager which is built-in to the Samsung My Files app. The Samsung Network Storage Manager allows you to access a shared folder or a drive partition from your PC's hard disk using local home WiFi network over FTP (File Transfer Protocol) or SMB (Server Message Block) protocols. This shared folder from your PC can contain hundreds of movie files as PCs have larger storage spaces often ranging from 500GB to 2TB or more.

However, this method is exclusive to Samsung Android phones. Samsung Network Manager is not available for other Android phones. However, you can use VLC media player's local network streaming feature or check if your phone's file manager doesn't support network storage management.

FAQ: Got Questions? I’ve Got Answers.

Q1. Why is there no sound after I switch languages?

It’s incredibly annoying, but this is usually a codec issue. Basically, your phone's built-in player doesn't "speak" the language of high-end audio formats like DTS or AC3 (Dolby Digital) or eAC3 (Dolby Digital Plus). To fix this instantly, just open the file in VLC—it has most of the "translators" (codecs) built-in so the sound actually works.

Q2. My subtitles are in the wrong language now—how do I fix that?

It’s a classic headache: you switch the audio to English, but the subtitles are still stuck in the original language. Since dual-audio files usually pack multiple subtitle "tracks" too, you just need to tell your player which one to show.

If you’re in VLC or MX Player, tap that same Subtitles/Speech Bubble icon where you changed the audio. You’ll see a list of available subtitle tracks—just pick the one that matches your language and you’re good to go.

Q3. What if the voices don't match the lips (Audio Sync issues)?

This happens all the time with dubbed movies. If the audio feels "off," don't panic. If you’re using VLC, tap the audio icon and look for "Audio delay." You can manually nudge the sound forward or backward by a few milliseconds until it perfectly lines up with the actor's mouth. Problem solved!

Q4. How to check if your movie file supports dual or multiple audio streams?

Open the movie file in VLC media player and then tap the 'Menu' button (three horizontal dots) in the bottom-right corner. A list of tools/options will appear on the right side. Scroll down this list and tap 'Video information.' If you see multiple entries for 'Audio' section here, your movie file supports multi audio streams.

Conclusion: Enjoy the Show!

There’s nothing like getting lost in a classic movie with the perfect sound setup. Whether you’re sticking with the Samsung Video Player or leveling up with VLC, switching to your favorite language should only take a few taps. Don’t let a "dual-audio" file intimidate you—once you know where the settings are hidden, you’re in total control of your movie night.
