Working on Mi Mix 3, thanks!
If anyone gets Dolby working please let me know, I kind of like it more than v4a.
Seyaru can you please update for Mi Mix 3 (Perseus)? I've uploaded the mixer files to gdrive.
I've updated it myself, feel free to add it to OP.
It's not working anymore on latest Xiaomi.eu and Mi Mix 3.
Flash the latest xiaomi.eu weekly.
It's working on P Smart as well, will be testing more tomorrow.
