The OnePlus 6T is easily one of 2018's best value phones for many reasons, especially when it comes to rooting and modding. But like many new phones, it's plagued with the single bottom-of-the-floor speaker.
By utilizing the Dolby Digital Plus Magisk module by repey6, you can turn your speaker into one's puncture well above its weight. This works for both the phone speaker itself and your headphones as well. No complicated setup here – just a few quick settings and you're good to go!
Before you can begin enhancing the audio on your OnePlus 6T, you want to download the core module to make this whole thing work.
Once you've downloaded the file from above, make sure it's located in the "Download" folder on your phone.
Next, you must open the Magisk Manager app so you can begin flashing the file onto your device. From the main screen on Magisk Manager, tap the menu icon on the left, go to "Modules," then tap the plus sign button at the bottom. From there, navigate to the "Download" folder, followed by tapping the main installer file.
Now that you're back up, head into the app's drawer of your home launcher and you should find a newly installed app called "Dolby." Open the app and then make sure your media volume is low before proceeding. The normal volume level you are used to will be changed, so that's something to be aware of while using this module.
Typically, this option is now broken. Do not worry about it; you probably do not need it anyway.
When you want to watch movies, this option should make the vocal audio stand out more than usual while maintaining some bass for good sound effects.
While listening to music, this option should make the audio a bit more punchy with a bit more bass to enhance the audio.
This setting can be used to amplify the overall volume quite a bit.
While watching videos on YouTube or listening to podcasts, this option will specifically cut out the bass and soundtrack
You have two custom profile options (Custom 1 and Custom 2) where you can tweak the audio settings and make one for yourself.
When you tap any one of the profiles in the app, you will be presented with a new screen with multiple options to choose from.
