How to restore full audio codec support (AC3, DTS) in MX Player, Android's best video playback app

How to restore full audio codec support (AC3, DTS) in MX Player, Android's best video playback app
Due to some licensing issues, many loyal users of what's arguably the best video player for Android sooner or later find out that the sound in the movies they just loaded for that long-haul flight wouldn't play in MX Player. 

We are talking AC3, MLP, DTS or Dolby here, which usually means that if you load a high-res, high-quality container with your favorite TV series, you might be unpleasantly surprised that the sound won't play mid-air, when you don't have access to the Play Store to get an alternative like VLC or KMPlayer. 

Moreover, why would you have to give up the amazing MX Player for such a small nuisance? The thing is, you don't, and here is what you have to do to restore full audio codec support with MX Player on your Android device, courtesy of XDA-Dev senior member ktsamy:

1. Download the AIO 1.7.32 codec package zip, and transfer it to default Downloads folder on your Android phone or tablet. This all-in-one package contains the codec versions for hardware decoders there are - Arm v7-Neon, Arm v7-Tegra3, Arm v7-Tegra2, Arm v6 VFP, Arm v6, Arm v5TE, x86, MIPS - preventing you from trying to determine which one you have on your gear;

2. Fire up MX Player, and go to Settings>Decoder>Custom codec (scroll to the end of the list for that one);

3. Point the basic file browser to the aio.1.7.32 zip file you just placed in the Downloads or another folder of choice;

4. The MX Player will automatically pick the right codec for your device, and restart itself to finish the process;

5. If you want to check if the codec pack has definitely been set as default, go to the three context menu dots up right, choose Help>About, and you should see it reading "Custom codec 1.7.32" - this way you will know that the right codec has been installed properly for sure. If for some reason sound doesn't play, check the Settings>Decoder options, and set it to "Use H/W+ decoder" or "H/W+ audio on S/W video," if you have set software video decoding previously for some reason;

6. That's it, you can now play any video file with sound on your beloved MX Player. Enjoy.

I used to enjoy watching movies on my tablet but since I "upgraded" from my Nexus 7 2013 to the Galaxy tab pro 8.4 it's been a nightmare. Almost none of my movies or series will play. I have tried different players, tried a custom ROM, converted the movies before I transfer them to the tablet and nothing works. I have even followed these instructions before and they did not work. It only says format not supported or something like that. I'm so dissapointed. :(

Tab pro 8.4 has a snapdragon 800. It shouldn't have this problem and should play even 4k.

I have this problem once with my Galaxy Tab S 8.4, no movie files no matter what format will play. I know something is up. I reboot the device and everything is back to normal. It only happen once, so if yours happen every time I think it could be hardware issue.

Well it is not with every movie. For example it plays three of ten and it is frustrating, but i have noticed it plays DivX format so I will try to convert them to that format to see what happens.

If ANYONE says it doesn't work, YOU'RE WRONG, THE INSTRUCTIONS SAY TO COPY AND PASTE = PLACE+ TRANSFER THE FILE TO YOUR DEVICE "DEFAULT" DOWNLOAD FOLDER. THE ZIP FILE AS IS. MXPLAYER WILL DO THE REST OR FOLLOW THE EXACT INSTRUCTIONS. Disclaimer, I have MX Player PRO and it's WELL WORTH THE MONEY, I UNINSTALLED ALL OTHER PLAYERS CAUSE EVERYTHING PLAYS WITH MXPRO. I DON'T WORK FOR THE COMPANY EITHER...

On xda forums you'll find a new version of this codec pack (for mx player 1.8.0). Just do a google search "MX Player Custom Codec with DTS & AC3 Support (by ktsamy)". Part in the brackets not required.
