[PATCH] Enable AK4490 HIFI DAC on custom Rom

[Skrem339]

Hi. I've created a patch that enable AK4490 on custom roms. Previosly it was pasted on 4pda.
Sry for bad English
If you are using latest Ainur betas from telegram you dont have to flash it because since beta 3 or 4 UltraM8 helped me integrate this patch into mod. Also Ainur doesnt have bag with call

Updated Magisk version to template 15000

Known bags:
When you call somebody you can not hear your subscriber. Solution: just enable and disable speaker mode.

UPD. If you're using OREO Rom, you dont have to use this mod because it was integrated into Rom. Plus if you're using Ainur, you dont have to flash it too

I thought that it was enabled by default on custom roms anyway? Or is this patch only so it works for sure with ainur?

If I understood right, no, patch will work without ainur

I also thought that, but I dualbooted LOS to try if the 192khz hack actually worked with the AKM DAC (because it was supposedly the one in use) and it was too obvious that it actually wasn't in use. The soundstage of the other DAC is much smaller. Maybe with this patch we can put it @ 192KHz with Poweramp? Can anybody try?

Any chance that this will get integrated onto the ROMs themselves? This is the same as the Universal Bootloader stuff and the old TWRP it installs, we'll get to the point where we need to install dozens of zips to get a fully working system

p.s where can we get the Ainur betas?

Do you mean this patch is exclusively for Ainur to work with the DAC? Because custom roms have been working already in most apps with the AKM DAC.

That's what everyone says, but dualboot stock and a custom ROM and using sound in LOS is like toggling the sound switch to standard

Nope, it not only for Ainur because DAC doesnt work on Custom roms expect AEX.

Really? I thought DAC was running OK on LOS... What about Pure Fusion and other ROMs? They say that high quality DAC is ALWAYS in use... I want to know what to flash when my phone arrives, DAC was mainly the reason for buying it.

You want to know what to flash? Well this here zip is a start

Or stay stock lol

so no need for anything else just flash? even custom ROM?

i think it is only custom ROM. Wouldn't make any sense if it was for stock since you have the hifi switch

This is probably the best mod I've flashed on my phone. This + poweramp is magic. I tried Sauron (even joined the telegram chat) but it sounded very low and saturated. This is another story...

Awesome work, really.

What is your audio output setting on Poweramp?
I cannot get the Hi-Fi plugin to work.
Thanks dev for the mod

The Hi-res output? No, that doesn't work. But at least the AKM DAC is working. I'll try using the Samsung UHQA hack but I don't believe it'll work (it may just put the sd820 DAC at 192KHz

I enabled HiFi audio with the Lenovo Hifi line trick in the build.prop file, and i think i got a slight improvement, but it may be just placebo.

The effect is really noticeable on the highs with a FLAC file. I used a 192KHz file to test, and the highs were awesome, but the soundstage got reduced a lot (this was on stock, so I went from 48khz AKM DAC to 192khz SD820 DAC). I'll try on LOS today

 

[Dodgexander]

I would love to understand the workings behind this. Once you install this how can you tell it works?

Please don't tell me to listen because that's pointless with placebo effect. I'm simply looking for the technicalities that prove audio is being sent via dac with or without this mod.
