[Fix] G8X Quad Dac on GSI Roms - LG G8X ThinQ Guides, News, & Discussion

Hi.
For people that are unaware some LG phones have almost and even no custom roms at all, that is the case with the G8x which is a shame for such a great phone,
fortunately something called Generic System Image (GSI) exists, it is a way for to get a custom rom with basic functionality for a wide range of devices.
I love the Quad Dac, it is one of the main features of a flagship LG phone, unfortunately it almost no developer owns an LG phone anymore so nobody is fixing it on GSI roms.
fortunately i found a kinda dirty way to fix it.
there are quite a few steps, so please be careful and pay attention:
1) On a stock (i used a11 iirc) rom Flash crDroid, other roms may or may not work
2) Flash TWRP and reboot to recovery
3) Flash your favorite GSI, i used crDroid 9.1
4) Flash Magisk, Flash Disable_Dm-Verity_ForceEncrypt if you dont want your data encrypted
5) on the magisk app flash LG-G8X-hifi-quad-dac-fix-GSI.zip
6) Reboot your device and a new "Quad Dac unavailable" icon should appear on the status bar edit
7) Plug in your headphones, touch it and enjoy!
Bonus* Hold the icon to enter the app and modify some stuff
Bonus 2* DP Should work, idk if Dual Screen works since i dont own one
Bonus 3* AOD also should work.
Just to clarify, i didnt develop neither the app, the files or the scripts, this was based on Fasheng's job,
the files were replaced from Lineage 19.1, i just put everything together so if something doesnt work
i may not be able to fix it.
Also, this may work on other LG devices (like G8, G8S, V50, V50s, etc) if you provide a rom for it.
you can use stock rom as a base but this may not work for you.
Changelog:
1.0.0 - Initial Release
1.0.1 - Removed incorrect steps on the description and readme
Enjoy your music!

Hello, thanks for the contribution, I got mine too work on my g8x. I was wondering if you could maybe share the APK as well. Mine only toggles on and off but won't launch the app.

i did it with TWRP, in order for the DAC to work you need to flash crDroid zip for this device as a normal and then you flash your preferred GSI.
There are plenty of guides on the internet for flashing a GSI, i can give you this one but any should work.
