I have owned LG V30/40/50 primarily for music listening. The downside was to activate the high impedance mode (for earphones under 50 ohm), one had to go through various processes involving adapters and cables. The other option for rooted devices was to edit the MIXER_PATH_TAVIL.XML file. That triggered the high gain output permanently.

For V60, that option is not directly available. The reason is that /vendor/etc/mixer_path.xml is located in super partition making the file not editable. So you could only force the high impedance mode by using adapter or cable option till now.

Using Magisk, I have written two modules that will allow you to substitute the system file and put your phone in high impedance mode permanently. Magisk simply loads the edited files as the effective ones (disabling the system file). You will notice increase in volume/gain when you enable/disable DAC in sound settings.

So I have Viper 4 installed with my module without any problem producing enhanced sound output from V60.

INSTALLATION:

1. Download the attached modules. Do not make any changes.
2. Save it on your phone.
3. Go to Magisk module page and choose install from storage option.
4. If you already have AML installed then uninstall that first.
5. Direct Magisk to the file you just downloaded. Now install AML first.
6. Reboot.
7. Install the Mixer.zip second (for high impedance effect) with Magisk.
8. Reboot.

Enjoy!


P.S.: Audio Modification Library (AML) has been modified to accomodate this module. Now you can use this module with all audio modules in high impedance mode!
