[Galaxy S 4 Q&A, Help & Troubleshooting] krasCGQ:
The extra/local version (after 3.4.0 or whatever actual kernel version) is the changelist (correct me if it doesn't).

dpi@SWDD5922 #1:

dpi <- This is the username who compiled the build.

SWDD5922 <- Host PC where build is compiled.

#1 <- How many revisions have been done.

You can easily hijack these three values by exporting these before kernel build:

$ export KBUILD_BUILD_USER=<username> # Export a fixed username who build the kernel, ignoring current session's username
$ export KBUILD_BUILD_HOST=<hostname> # Export a fixed build host name where the kernel is built
$ export VERSION=<version> # Export a fixed revision, so it won't count at all at every dirty compile (make clean and build again)

If these values aren't set before build:

KBUILD_BUILD_USER is determined by 'whoami' command. 'whoami' command will always output your current username.

KBUILD_BUILD_HOST is determined by 'hostname' command. 'hostname' command will always output your PC's host name.

VERSION: It'll be 0 until a build is successfully compiled. Everytime build is compiled, current VERSION will be added by one and will reset when 'make mrproper' and 'make distclean' is passed from terminal.

As final note: It has nothing to do with the final kernel. The kernel might be compiled on different PCs.

Hey everyone,

i have Redmi 4 Not prime. i noticed the only difference is the display and battery.

I couldn't find a forum for regular redmi 4 and i was wondering.

Can i flash Redmi 4 prime roms to my Redmi 4???

Thanks

EDIT: i meant to post on Redmi 4 prime not here. please move the thread. sorry
[Miscellaneous Android Development] Nemorosus:
Redmi 4 and Redmi 4 Prime have the same batteries...? But anyways, no, you can't. Redmi 4 has a different SoC (CPU/GPU) with the Redmi 4 Prime.

Redmi 4A > Snapdragon 425

Redmi 4 > Snapdragon 430

Redmi 4X > Snapdragon 435

Redmi 4 Prime > Snapdragon 625

None of them is compatible.
[Miscellaneous Android Development] torecdude:
Where can i find ROMS for my device??

edit: so if redmi 3s has snapdragon 430 i can use its roms?? i guess not right?
[Miscellaneous Android Development] Nemorosus:
95% no without tweaking and porting many stuff. It's the same as Redmi 4 Prime and Redmi Note 4 (SD version). They both have SD625, but their ROMs aren't interchangeable. Not many ROMs right now, but try PDA.ru or the Xiaomi forums if you can't find anything here.

Redmi 4A and Redmi 4 don't have any custom ROMs atm except for MIUI.eu (I may be wrong, not 100% sure).
[Miscellaneous Android Development] torecdude:
Thanks alot!
[Miscellaneous Android Development] Kizoky:
Closest ROM you would find is the ROMs for Redmi 3S, they have the same hardware capabilities. (Same chipset, same display, excellent)

You just need to do a lot of porting to get it working

[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] mekanix:
Hi,

I am considering purchasing this phone and use it as a HiFi player. The reason is that it uses the Snapdragon DAC (same as the one inside HTC 10) furthermore, looks like the aptX/HD libraries, coming from Oneplus, work on it as well.

For those having this phone already, I have 2 questions:

- have you tested the sound quality on it with decent headsets?

- is the HiFi enabled at all times or only in it's music player? Some competitor phones display HiFi in the status bar to show the DAC is enabled

Thanks!
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] n00b_dr0id:
I have ordered the phone. Will confirm ASAP.

I thought it would have good DAC like Vibe X3.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] mekanix:
Tanks much - waiting your feedback :)
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] n00b_dr0id:
Received the phone today and tested the audio via Vivo XE800 and Monk plus. It's not good. The output volume is very low too. Monks which are 64ohms needed volume at almost 90%. Monks didn't sound as good,low end struggled. Vivo which is bright had even worse sound on these. Even speaker volume is very low. Tested via both poweramp and Neutron player.

Better buy a used Vivo X3 which has 9018k2m if you want just for DAP.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] mekanix:
Thanks n00b_dr0id, highly appreciated!!! Will continue using my BQ M5 (wolfson onboard) and will keep it a bit more; thought I can jump to a better, more up to date platform but looks like I have to wait
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] mekanix:
Do you plan to return or keep it? For the later, I guess you will test some custom roms - maybe the sound improves with a different rom...
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] Nordicus:
Of course, you should try on custom firmware based on MM.

At the 4pda conference there are feedback about the sound output Hi-res 24/192 using Poweramp (beta). And also additional mods Ainur pandora and Davine beats.

To amplify the sound, V4A and Magisk modules were used.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] n00b_dr0id:
I do intend to keep it and use custom ROMs since the Stock UI is pretty bad and hogs almost 45% RAM without any app running. But as I am reading a lot of complains online about this device's unreliability so I am not going to unlock the bootloader anytime soon to void warranty. Right now I am trying to find a 'certified' USB C to micro USB cable to connect an external DAC. If you guys have any idea about this pls do report.

P.S> Since this device doesn't have OTG I am not sure if external DAC will work. Will find out.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] Diesen_Dev:
Just received Z2. Well... It sounds pretty awful, expected more from this device. No software will help if hardware implementation of codec is bad.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] myeviltwin:
So you mean to say the speaker sound will remain like this even if we install a custom rom.. I remember for galaxy note 2 there was an add on to increase the volume to max
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] Diesen_Dev:
I have no claims to speaker, it's pretty loud for me, both on stock and custom. Zuk has the most loud speaker from devices that i owned. Just not satisfied by headphone sound. I listened it more, it's not so bad, but not HiFi level, as all phones without dedicated DAC. Anyway, Xiaomi Mi5 with same built in Snapdragon DAC sounds little better.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] tuxdude143:
From my experience the headphone sound is... Ok but not amazing. It uses the in built SD820 DAC and I've had an overall mixed experience. When hooked up to my Sennheiser HD 215's the sound given by the Z2 is passable but nothing special. After installing the Arkamys 2 sound mod (which is more of a tweaked codec than anything else) sound quality did improve a decent amount but it still isn't going to beat out a proper HiFi music player or hell even a sony droid phone.

In my opinion at least sound quality is... passable but it isn't going to win any awards any time soon. Stuff like the Arkamys sound mod do help improve it but again because the DAC is the one built into the SD820 it's kinda expected. I mean, for a phone at this price point a few corners would have to be cut somewhere. Either way if you're really serious about your music then just stick with your current setup.

Despite that though the Z2 is still a really nice phone and is well worth picking up if you want a nice powerful phone while you're on a budget

[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] n00b_dr0id:
Sound from Lyf Flame 1 which has same SD DAC has better audio compared to ZUK so it would should improve with custom ROM and with further enhancements like V4A it should help it reach it's max potential.

So I did the whole thing...installed AEX ROM and listened to my fav songs via the 'phonograph' app pre-installed in AEX and it did sound better than the stock ROM. In fact, it sounds exactly as SD DAC in my other cheapass phone. Then I installed ARISE system with V4A and profiles etc and it didn't make any difference for normal settings if you want coloured sound then those profiles can definitely be of your help.

Dear All,

I have Z2 Plus with AEX 4.6 ROM installed. I want to enable/use built-in DAC.

I have read in many forums/threads like:

https://xdaforums.com/lenovo-zuk-z2/themes/b-audio-mod02-06zuk-z2dac-haxdual-t3630841

This mod says that it will enable CLS_H_HIFI mode.

Then there is another thread:

https://xdaforums.com/lenovo-zuk-z2/development/rom-crdroid-v3-4-t3618780/page6

This says that it will enable S24_LE and CLS_H_HIFI both.

There is one more site, which talks on using something like high performance DAC enabler.

I am confused, which one should I use. Also, how can I see whether the DAC is actually enabled and working. I have read that someone has bricked his 3.5mm jack in the process.

Request your expert guidance to enable built-in DAC and experience 24-bit music. The only thing so far I have done is unlocking the bootloader, flashing TWRP and installing custom ROM like AEX.

Please help.

Regards,

Amit

For 24 bit FLAC playback make sure you're on marshmallow
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] n00b_dr0id:
Where does it say that phone has two DACs inside? DAC refers to digital to analog converter chip without which the digital signal from music files can't be converted to analog signal. If sound is being played that means it's been processed through the DAC. What am I missing here? Unless the phone has two DACs one low-fi and one hi-fi there is huge misconception. Also, 16bit or 24 bit doesn't really matter if the DAC quality is bad.

The only one customized ROM that works properly with audio hi-res is Paranoid ROM (24bit 96Khz).

I have tested only these three ROMs.

I'am use Radsone Player for test.

ps: poweramp is not useful for testing because it does downsampling.

Hi Juniofdm,

What configuration you did/have to test Hi-Res Audio?

I tried with Paranoid ROM and Radsone Player but no success. AIMP sounds louder in the same ROM.

My Configuration is just the Paranoid ROM. No custom kernel, no SHOX Mod and no Ainur Mod.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] juniofdm:
I tried with Paranoid ROM and Radsone Player but no success.

>>> How unsuccessful? Not play? Have a noise? Some error message?

AIMP sounds louder in the same ROM.

>>> It seems to work on hifi (observing his settings), but I will check with other ROMs to see if it is doing downsamplig or not.

My Configuration is just the Paranoid ROM. No custom kernel, no SHOX Mod and no Ainur Mod.[/QUOTE]

>>> I use only Paranoid Kernel without any customization.

I know that Radsone player does not downsamplig because in devices without HIFI (16bit 44.1khz) the audios get noises or cutting. If the audio is not compatible with the hardware characteristics, it plays anyway. Otherwise it plays with audio failures.

Radsone player:

Áudio file 24bits 96Khz + Phone 16bits 44.1Khz = Áudio failures, noise and clipping = No downsamplig. :good:

Other tested players (Play music, PowerAmp, Neutron):

Áudio file 24bits 96Khz + Phone 16bits 44.1Khz = Áudio job fine an clear = Have downsamplig. :(

This night do test with AIMPplayer in my Moto X Play (16bit 44.1khz phone), and in LineageOS(16bit 44.1khz without hi-res library files) with my Zuk Z2 (Hi-res hardware phone), and post the results.

There should be an application that shows the current sample rate and bits of audio playing... Would help a lot.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] n00b_dr0id:
Sample rates don't matter. It's a goose chase. AIMP is the way to go.
[Lenovo ZUK Z2 (Plus) Guides, News, & Discussion] juniofdm:
I give up trying. There is no way to know the true sound quality that is being playing on the smartphone.

If the music app says it's 24bits we have to believe... If the music app says it's 192khz we have to believe... :(

But it may just be the developer's disappointment to sell more...
