Not sure if this information is useful to anyone but here it is.

Basically after nougat update Poweramp music player's 24bit playback mode fails to activate (even with latest 704 alpha installed). So those audiophile among us might be super annoyed .

Solution, add this line to build.prop , this has enabled 16bit 192khz playback on aicp7.1.2

ro.lenovo.hifi_support=true

Small update , it seems that someone on the Poweramp forums has managed to enable 24/192 playback by tricking the phone into thinking it has Samsung software .
Anyone have any idea what he added to the build.prop?
If you want the best audio you can get out of your phone, install viper4arise. (and use esira/eleven)

Edit: Viper does not activate 192khz playback, because its useless (for a smartphone with only 1 aux output) read why here.

Hires audio is a complicated subject. I think it works for me because of the placebo effect ? Lmao
However, I'm also just a hobbyist looking to tinker around.
If I can recall correctly , most forms of audio mods on Android increases the noise floor by a significant amount, making everything sound quite messy (but I haven't tested arise yet) .

Just looking to share info around and spread the fun of tinkering

I had this problem with arise too, but you can reduce the "output gain" to reduce the quality loss while amplifying the signal (just remember to set it back if you need a louder signal, e.g. for small speakers). Like that i was able to completely anulate the small glitches and rushing/shizzling (or at least i dont hear it anymore xD).

I've tried dozens of sound mods (even changed roms for it) and the best (and most stable) solution for me is viper.
You however have to try around and install the arise modules one-by-one and then setting everything suitable for your needs (Profiles, add-ons like atmos).
But its worth it, even my 24bit 192Khz computer sound sounds bad now! :crying::p

Seems pretty fine to me but I didn't play with it much since non of my earphones seem to respond well with it
What Earphones do you have?

For my somic/Xiaomi In-ear's it works perfectly (Arise core+atmos +Sono's headphone profile) i only use Atmos for more bass (e.g. drum n bass/goa).

But Mi4c/s is a ***** concerning audio (i think to remember flashing rom for rom to get good audio, but thats some time ago) xD

Kz zse , zst
And a piston hybrid
Yeah smartphone audio might just be average unless if its a LG V series .
Either way I'm planning on saving up for a dac or perhaps DAP in the future haha.

The Piston hybrid sound damn good to me with Sonophilos headphone profile and dolby atmos (but i'm on Oneplus2).
Make sure you get a DAC thats supported by viper if you get one ;P

I bet this one will work, tested on redmi note 4 mido

Change ro.product.manufacturer=Samsung
And add these lines from audio lines= persist.audio.uhqa=1

Hope it works, thanks me later
This trick just send 192khz audio PCM data to Android audio resampler, after that audio data will be resampled to 48khz/16bit for output.

For me this line is the one that works.

However, in my hi-res output option, DVC is always enabled.
As it's conflicting with Dolby, how to forcefully disable it?
