For anyone curious like me, here's a little more insight into what's actually being activated in high performance mode: https://github.com/PDesire/PDesireCoreKernel-Kitakami/blob/ce9f7c1111e227bee968304c682869c25ad5003f/Documentation/pdesireaudio/api.txt

Update:
After looking at the source code for confirmed WCD9385 devices like the Zenfone 8, I discovered that high_perf_mode has now become CLS_H_HIFI DAC mode within the kernel source code. I'm not the first person to look into this apparently, there has already been some successful work done to enable CLS_H_HIFI DAC mode here: https://xdaforums.com/t/kenzo-kate-audio-mod-30-04-19-shox-audio-mod-v4-reborn.3598455/

Unfortunately, the download links for that mod are currently broken. If I can manage to find a copy of that mod's files floating around I can use it to learn a bit more about activating CLS_H_HIFI DAC mode, otherwise I'll have to start from square one.

Wow, so it looks like someone was far ahead of me and has been able to come up with something that works for newer Snapdragon Devices: https://github.com/Briclyaz/NLSound_module_QCom

@FunkyNico you may want to check this out.

They have not been able to get HIFI mode working without issues yet though, but the mod itself is incredibly extensive and they have an incredible understanding of Qualcomm's audio interface.
