[DEV] Voodoo Sound for Optimus 2x and G2x

Hi!
After a ton of requests from you guys, I finally decided to take the challenge to write a Voodoo Sound port for this WolfsonMicro WM8994 powered phone.
So I bought a device just for that, because it was just impossible without.
As stated previously, this phone don't have a proper sound driver, or at least not a Linux Kernel driver.
There is some kind of non-standard userspace audio implementation inside /system/bin/nvrm_daemon.
This daemon sends directly i2c commands via a NVIDIA proprietary API, which has an interface running as a bunch of foreign code in Kernel in order to access the hardware.
Why this port is a real technical challenge, requiring a fair share of reverse-engineering, lots of head-scratching and a very hacky state of mind?
Because it's not supposed to be possible. But, eh ^^
I have an Optimus 2x since a few days only so I don't have much experience about what needs to be improved, apart from the obvious:
- Sound quality.
- Headphone amp volume.
- Creepy speaker output.
As usual, most of my work is under GPL and Kernels developers/packagers are welcome re-using my patches.
If possible, I'll also write an in-app implementation, not requiring a patched kernel in Voodoo Control Plus.
You can follow the dev work here:
github.com/project-voodoo/linux_lge-p990/commits/froyo-voodoo-sound
I commit code real-time so if you're curious you don't have to wait for release to play with it!
PS: targets are Optimus 2X official and CyanogenMod, G2X official and CyanogenMod

That would be real great... yeah sound quality needs a boost up. Thanks in advance.... i have big hope for it to work

Me too, that would be great

sounds great, can't wait

Awesome !
Yeah damn proprietary drivers. Wanted to port your stuff from the nexus s but then yeah.. nearly everything is closed : /.
Anyway you are way more skilled then me so let's see what you can do
For headset boost you can have a look at this https://github.com/VorkTeam/vorkKernel-LGP990/commit/7db46bc4a778dc89d6de7d1550c8e3b3d0fe00a1.patch . It's just a finished sysfs implementation started by lg. DebauchedSloth wrote it (found it here ). He wrote a app for it too Github.

Freaking awesome! SGS, Asus transformer and now 2x, you're rocking dude!

Looking forward to this and will make a donation as soon I HEAR any improvement on my LG O2X CM7 running device.

Nice can't wait for this!

With MIUI coming officially next week, it would be nice if it is included too. Just a suggestion but welcome onboard the O2X community

Brilliant
Voodoo sound is the main thing I really miss having from the Nexus S

neeeeed
can't wait

really hope you can make this work

does this mean that a2dp will work after youre done?
if yes this would be frikkin awesome

This is perfect! The sound (n battery) is The main reason for not using fr org. For me its a trade off because I really line the org. camera. This way I can stay org. With great sound! (FR org. Sucks I think).
Thank U

Sorry for this noob question but what is difference between voodoo sound and dsp manager or volume+ ?

No pb!
Voodoo sound work directly at hardware level.
This way I can fix issues at the lowest level, use the full potential of the sound chip, increase quality.
Other solutions are software effects: cannot improve the sound quality or increase the volume for real, eats some CPU and add latency.

BTW I found theoretically how to hook Voodoo Sound driver without flashing a custom kernel yesterday, I'll try the concept today.
This way, Voodoo Control Plus should be able to load the driver on rooted devices.

sounds good when do you think it will be ready

[SOUNDMOD][05/05]FidelityXAudio - Ultimate high fidelity audio

I'm building a new ROM for my new Xperia Z right now mainly for even better audio quality. However, it'll take a while as I plan to try rebuilding audio driver library file for lower latency. Right now I'm on vacation staying at my parents' house so I decided to build this sound mod for Samsung WM8994 devices instead since I have good chance to reunite with all of them right now.
FidelityXAudio is based from PureXAudio for Xperia Z/ZL made by ZeroInfinity. I asked him for permission to derive his works with mine for all-in-one sound mod I plan to release for various devices that support Alsa driver. For this first release, it'll support Nexus S, Galaxy S, Galaxy Tab and Galaxy Tab 10.1 and all variants. Installing this mod will give you the following features below.
Features:
Rooted & Busyboxed - This will replace current root and Busybox with latest SuperSu and Busybox. Since most root access for Xperia Z I tested are so unreliable getting bootloop after mounting system rw, I'll force better ones in this package to avoid that problem.
exFAT support - If you're using Android JellyBean ROM but still not have exFAT support yet, this may help you getting one. It works for Xperia Z/ZL but haven't tested for others yet.
init.d support - This isn't cheap recovery flash init.d script. It'll execute init.d script with root access from hardware boot script level so it works far better than conventional ones for locked bootloader running stock kernel.
Xperia Fidelity script - It's ultimate sound quality mod script I've been developing for years. Not only get you better sound reproduction but also make your system smoother as well.
PureXAudio engine - As FidelityXAudio is based on PureXAudio mod, most PureXAudio features are availble except audio effects and specific sound card stuff. I may consider adding them back later though.
Low latency tweaks - My tweaks inside PureXAudio for lower latency Alsa configuration. Not sure how much of it works though as real measured hardware latency won't change without modifying driver.
Mastering 64-bit quantization - The most accurate 64-bit floating point quantization in Android. I usually end it with 32-bit integer mode but this sounds better for crazy upsampling level.
DSD128 audio processing at 5.6MHz - This will give you high resolution audio simulation. The real sampling rate will still be 44.1KHz but with 128x upsampling for audio processing before downmixing is really something.
Fidelity nVIDIA audio configuration - Optimized for more direct bitstream with lower latency. Only for Tegra devices though.
Removed DSPManager for more solid audio performance - This mod breaks DSPManager in CM ROM so no point in keeping it and you probably won't need it anyway after hearing sound with this mod.
Download: PureXAudio v1
You can't flash this on other devices as it can break audio with incompatible sound card configuration. I tested on my Nexus S, Galaxy S, Galaxy Tab and Galaxy Tab 10.1 and they're all working fine. Guess not many people still use them nowadays but they're great ones for sound quality wise. I'll update again for APQ8064 based devices in next version after releasing new Xperia Z ROM.

Wait I'm trying it will report back soon:thumbup:

Yeah its working well and i can hear a little bit difference in the sound but the music sound is loud now So, its working awesome :victory::highfive::good:

I can use this on 4.2.2 rom ?

It's designed for JellyBean ROM so yes.

Yes i tried on a JellyBean 4.2.2 Rom and it is working well :good::good:

Don't know if its a placebo but I seem to be able to crank up the volume much higher now before it starts to sound distorted, on lower volumes I cant hear any difference
anyway thanks for the mod will start using it daily and probably damage my ears :laugh:

Huh?.. can you speak up.. I can't hear you over this great mod!!

someone please reup this, thanks

Will this mod work alongside voodoo sound, or is it an alternative?

It works alongside with Voodoo Sound. Actually, I added my own Voodoo Sound tweaks as well. Some may not like it but that's what I prefer.

What headphones/earphones/speakers do you usually use with your devices?
This information is useful for me. Thanks! :good:

I used to try all in market years back but now I don't really care much even R10/Orpheus failed to make my desire go wild now.
My current favorite earphone is Martin Logann Mikros 70. Not very bang for bucks but easy to wear with mic and bass sounds like speakers with dynamic driver in that long housing.
My current speakers is Rockport Ankaa. I like it more than its newer Avior models.

hello I flash this but I don't think is working for me..i don't find any different ...
I install busybox again with busybox.apk is ok ??

If you already use other soundmods, maybe it's possible that this won't work. Otherwise, I don't see any reason why not as I already included root/busybox/init.d stuff.

I don't use other soundmod.. I don't know maybe I don't understand the sound ... for busybox I install 1.21.0 ..

It works on JellyShot 4.2.1 v1.3? I flash it with CWM? I have Voodoo sound... It works fine too?

i'm sure that you will make this face when I tell you that i'm using CyanogenMod 7.2...
... so the question: it's only for 4.2.2 roms or it will work with every android os?

Should there be an app to control this?
Me Gusta!

Galaxy mini system optimization

I mean to reduce the consumption of RAM and speed up the application for galaxy mini. I heard about PROGUARD but this program does not want me to work (only works on jar files and not apk) In short, wants to speed up the system by an independent editions. Give me some examples. I use android 4.2.2 cm 10.1

i think odexing would help.

I can oddex rom , but what's next

Suggest you to try Seeder... it reduces lags really effectively..
Also,despite I am not sure if it does work on cm7(i think it works) you may search for V6 Supercharger. .

Problem with using CM10.1 is eventually the phone becomes very laggy and slow.. Our phone isn't very capable of handling JellyBean the way we expect it to.. Try seeder as mentioned above..
P.S : For speed and nice gaming experience (as per our Mini Standards) i really prefer CM7.2 modded with seeder, adrenaline engine or similar script along with Chainfire 3D (Actually Works very well for me!) Just felt like sharing

[App]NooTuSound Alpha

Hey Ho
In my free time i have develop an app (made in one hour) by far not ready, but i thing you can test them.
The features are Headphone analog Volume up to +1 .
High Performance mode.
Tune Speaker more bass and good balance without distortion.
Louder speaker mod but with the tune speaker mode with less bass (to reduce distortion).
This is not a big thing but i can learn developing android apps and why not share it
ther will be bass boost mode.
- save settings and boot
- headphone plugin set
usw..
but without eta:silly:
need Alsamixer driver !!!
link down for the first alpha release :laugh:

You should share it in android development and hacking thread to get more testers.
Too bad for you i'm not into music or audio thing, so i can't test it.

Forgot about Voodoo sound?

Hey guys,
I was looking for a good quality mp3 player recently to use with my entry level ATHm20x and it was a surprise for me to find out that the old SGS had the best audio chip among phones. So, now i use this phone mainly as a audio player. flashed cm10.1 and installed voodoo control by supercurio and the sound quality is amazing.
I just wanna ask if the newer roms runnig android5 or 6 or support this voodoo sound? (roms with stock kernel)
Im currently on jb 4.4.2, its smooth and fast, how does new builds compare to this?
And its amazing to see the amount of dev support this phone getting, there's something magical about this little thing.
cheers

They do. Not sure about other LP/MM ROMs but i was able to play 24/96 flac files on Resurrection Remix using USB Audio Player Pro, without resampling.
