V30 Quad DAC Root Bybass fix - LG V30 Guides, News, & Discussion

Ive been playing about with this phone now and making a rom and in my expericance so far and from somthing @ChazzMatt said that I realized something was not quite right and it happened after i flashed a new 10c kdz and did the normal thing twrp + Magisk + Viper that i found the Quad DAC to not be switching on. Volume at 50 is nowhere near what i should be with it on compared to off. Ive found something in the build prop but im not sure if its just a coincence or this is actually doing something but 2 things might be the cause of the DAC not switching on.
1. Persist.audio.dmb_hifidac = true
2.Persist.audio.hifi_dac = off
Ive found that playing with these options and rebooting causes the DAC to switch on again. Maybe someone else can confirm exactly which of these keeps it working.

In custom CM/LOS ROMs with the 2016 ZTE Axon 7, which also has a quad DAC, devs could not use the quad DAC for audio processing. They had to use the Qualcomm Snapdragon audio processor -- as ZTE would not release proprietary source code for their award-winning quad DAC.
I believe stock based custom ROMs still had access -- as those were just debloated, tweaked ZTE firmware.
(Last time I checked was a few months ago, so if devs overcame that hurdle, then good for them. I only know the situation last time I looked.)
I do not know about the LG V20 custom ROMs, either stock-based or CM/LOS. LG V20 of course also has quad DAC. I've not researched. Maybe someone coming from V20 can tell us, either a dev or a user?
It's just the quad DAC on this phone is one of the main selling points, so you want to make sure it's being used if possible... Your ROM is stock based, but LG does have limits in place. For instance, it checks for impedance. And there's things you don't want to break.

Can confirm. After last twrp session updating to magisk 15 killed the quaddac.
Setting the values as follows and rebooting brought it back.
persist.audio.dmb_hifidac
true
persist.audio.hifi_dac
ON

Ok that's strange as I had it working on different settings.
Having just replaced my v30 twice. USB port broke on 1st phone then a vertical line was on the 2nd one I got. I'm now on my 3rd phone with your settings but nothing happened till I switched on viper master power and rebooted. There's some weird impedance thing going on with it.

Yeah it's strange. Everything worked last time with old magisk (I had to go back to stock and reflash twrp after updating to magisk 15 got me a bootloop)
It seems odd that rooting changes such things in build.prop

I woke up this morning and plugged my phone into my speakers and then later in my headphones I noticed the dac not coming on despite not rebooting since the last time it worked. So I actually switched off the dac and kept plugging in the headphones until I noticed a difference in the sound and then the dac just came on. No reboot needed again.

It's very strange. I noticed a short lag in sound when I tried to switch on/off dac and settings. As if it was about to change something but very delayed. Seemed like something was trying to do something but got stuck and never turned on settings or dac.
That was before I changed build.prop. After that all worked well. Like said before.
Could be that when i played around little more it would have switched on without changing build.prop. But did not have time to test because i was commuting.

What headphones do you have? I think it is to do with this. I just bought the Sennheiser HD630VB's which are only 23ohms. I also have the Momentum 2.0 over ears and the HD650s but ive only tried with the 630s and i suspect it needs 50ohms to really switch on DAC which in turn having Viper on would cause the checker to trick itself into thinking im running a higher impedance set of headphones so i need the dac on.

Atm im on vacation. I will look into it when I have the time. FYI I have ath m50x and teufel move inear
Sent from my SM-G935F using Tapatalk

so i've looked into it. my HP have 32 and 16 Ohm impedance.
they trigger the dac on when i connect them (after i changed the build.prop. it never stopped working for me again)
judging from this thread connecting higher impedance HP will trigger higher power output modes, but the dac is always on in the same way

If somebody was thinking battery test on youtube video streaming, i did that and got 8h 2min sot. Full brightness and volume.

can someone help me? have the feeling that my dac does not run since I use viper4android

with me the dac does not run with viper4android

Don't use that then. Instead use this:
Whiskeyomega's V30 Sound Mods
https://forum.xda-developers.com/lg-v30/themes/whiskeyomegas-v30-sound-mods-t3757115
What LG has done as made a bad job of the mixer_paths_tavil.xml which includes references a ES9018 which was never put in the phone or any phone AFAIK.
But what I have just noticed is if you are using a set of low impedance headphones, It goes through to the low power sound device chip but keeps the HIFI DAC switch working so the EQ can still work. Unless you make it think you are running a different type of headset which it calls "Advanced" which is high impedance then it runs to the decent DAC and there are no problems.
I have also noticed in all the mixer_paths_tavil.xml from around the world markets that there are differences in settings which should be the same. Which is what could account for some people saying Low Impedance still runs through the same decent DAC and some people saying it doesnt. Either way mixer_paths_tavil.xml is a maze of old and incorrect information.
So with that in mind. I'd Like to share the results of my work with more always coming.

Besides these standalone mods, some of this is implemented in at least two stock-based ROMs.

I do not want to use only the DAC, but also viper4android

Those mods improve the DAC so you don't need viper4android.

Ok, I have to try it. but there is no way to use both?
because in the first posts was that someone has used it together with viper

can it be because I installed a Costum Rom because the DAC is not running?

have the deep_buffer file restored. Now the DAC is running with Viper4Arise. I did not have to change any settings in Build.prop.

[Q] [RANT] Australia Vodafone LG G3 issues.

Hey folks,
Recently I purchased a LG G3 on contract from Vodafone Australia (I got the G Watch free so it was a sweet deal). Although I had been using an iPhone prior to this, I'm in fact an Android lover and fan. I was using the iPhone due to unavoidable circumstances (no cash for a new one and this one was lying around at home). I did a lot of research and reading up before going for a new phone and decided on the G3, given its killer specs and impressive reviews.
But it's been two weeks now and its just problems after problems. I've not even rooted or installed any mods or such.
Audio issues - Inability to connect to external device via AUX cable. Like there's a lot of hissing and static but no audio output.
Until recently, my Audio Technica ATH M50's were working fine but today I discovered sound is playing only from the left speaker and the right one just hisses and crackles. Like when i navigate menu's and make selections, the hissing fluctuates.
Also, when I put a call on speaker phone, the mic does not work.
Yet again, when I use the handset speaker for a normal call, it hisses and crackles.
Overall I'm really disappointed with the audio performance. Everything else is alright considering the device is running an OEM skin along with factory settings.
My question is, are there any fixes for the above issues I have listed? Are they hardware based (not fixable) or software based (potentially fixable via a firmware update or mod, if and such when one becomes available) Does anyone else in Australia on Vodafone have the same issues? If so are you considering trading back on warranty for a new one. And yet again, what is the guarantee that the new device will be rid of all these issues?
Thanks,
Sezy.

Use the warranty
I doubt it's Vodafone's fault, most probably lg's
The real problem with Vodafone is the coverage. It's only good for cities. I used to use Vodafone, now I'm on optus.
Exactly the same as I said here

I think a headphone amplifier would perhaps solve the 'issue'
Sounds like an LG issue. I'll also add that my included LG headphones are a lit quieter than any other pair i use

headphone sound stinks!

I am using an unlocked ATT G3 on cricket. I use Iheart radio while exercising, walks etc. I have noticed my wifes 39.00 ZTE phone has better sound through the headphones.
I have downloaded and installed countless equalizer programs through play store. They all seem to lower an already low volume.
I picked up an IDOL 3 from ebay and the sound is terrific.
Is there any hope for the G3?
Thanks
Try viper for android i use the expert settings can change how your phone completly sounds
I was under the assumption that the phone had to rooted to use this. Mine is not

Sound isnt as loud as other phones I have owned and there is very little bass and sounds like a transistor radio.
Sorry for so many questions but besides the headphone sound I really like the phone and would prefer to keep it rather than the plastic idol 3 I just purchased to try.
Does anyone know of an equalizer that works on this phone without rooting?
Thanks again for putting up with my quandary!!

Audi A4 Android unit feedback

Hello guys im creating this topic in order to find out more about this particular unit, ive already been searching the forum but i cant seem to find opinions on this unit.
Im thinking in buying this one instead of rns-e (original audi) because not only it is cheaper, but it also offers a lot more options since its an android unit. altough its a chinese unit and thats kinda what makes me get one foot behind this buy.. Is there anyone that has the same unit? or same hardware/software that could give me some positive/negative feedbacks?
The unit its this one.
http://www.ebay.de/itm/231594075480?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT
Quadcore 1.6
1024x screen
1gb ram
Heres a video of it working, appearance its similar, and hardware its the same i think

Thanks in advance for your feedback mate.
Can you tell me if the screen is good against the sun light, even on full brightness? Can you actually read things there while theres light in it?
How about the sound quality? Bass?
Thanks!!!
Hi @Ezreal,
I have that one (manufacturer KGL) installed in my Exeo and it works pretty well, only thing I am missing is the radio station/song names and well, of course the navigation instructions in the FIS/DIS screen that you can get only with the RNS-E...
Everything is working fine and would recommend that 100%, although I think I remember the original radio sound better. But that was over 1 year ago when I had that.

Well thats my fear too, i know that the rns would sound a lot better than this one, but well its expensive, and old, its not even touchscreen, although its OEM and wont have problems with GPS/Sound quality..
Do you recomend giving like 360€ for a chinese radio?
RNS its like 550€ +.......
Depends on your needs... If you want to have your car full OEM, then for such a difference go for a RNS-E, but if you want to have all the possibilities that give you android, then China radio... You can install tomtom + all the apps from android for instance and is more customizable...
If you use the gps a lot, I would decide the China radio, if it is only to have MP3 + basic gps functionality + full integration then go for the original one. Your decision

The thing is. I would like to have a radio that could reproduce videos like concerts and stuff, and many more stuff.
The RNS wont read video files.. but has a really nice sound quality, which i dont know if the chinese radio has since its not OEM.
I have a radio 1 din on my A4 and has a really nice sound quality, and bass etc. Im afraid i will lose that quality if i go chinese radio and not OEM.. What do you think?

Then go for the Chinese one. RNS-E will not give you out of the box what you are willing to play.
Sound quality in the Chinese one I think can be improved via de equalizer just adjusting manually the values, but didn't tried yet several combinations. Anyway it is not bad quality sound not to choose that one because one because of that, but I think it is little bit below the standard radio. I may be wrong as it is just my point of view.

But how about gps for instance? Does it work well? Crashes? Bugs?

Regarding music sound, I use the app "bass eq" and really notice the difference for better
Try Viper4Android!
Hi, I'm looking at getting one of these for my Audi A2. Currently the only option for the A2 is to purchase A4 RNS-E and modify it to fit the dash of the A2.
The question I have, which relates to your units, is that the Eirisn ES2028A states a resolution of 1024x600, and the pumpkin 11-C1220-UK-A states a resolution of 800x480.
Can anyone confirm if the Erisin does actually have a higher resolution screen, as I was on the understanding that they are all made by the same company (HuiFei), then distributed by different resellers (Pumpkin, Erisin, Eonon, Joying, etc).
Any help would be appreciated.

Well according to ebay, pumpkin is 800x, I think the others are all 1024x, but cant confirm 100%
Thank you for the quick reply.
Is it worth going for the higher resolution screen?
I've seen more info about Pumpkin versions than Erisin, so wasn't sure if it was worth going for the lower resolution screen and getting a possibly more robust headunit.
I'll keep an eye on the Erisin units then, unless the others update their screens.

Well i dont think its a huge diference between resolutions since the screen is only 7"..
If it was a TV i would go for higher resolution, but again, i can be wrong because i never saw both standing near me so i could test it.. I would wait for experts to come and take our doubts out..
But the price its kinda the same.. the 800 one its the same (sometimes bigger) than the 1024.. according to ebay..

For sure, it's nice to have another Audi on here with the same issues... my volume level is constantly up to about half (15) just to hear anything, then up to like 25 with the windows down and rolling.
Viper4Android installed, with the stock firmware EQ's basically all the way up and the "loud" setting on, has made a significant difference. I'm not sure why V4A says you don't have root... but I would reinstall it right after doing the root password and adb password in the system settings. I have constant root on the Malaysk ROM, so I am not sure.
I am also thinking about hitting up the guys on this website... http://enfigcarstereo.com/audi_radio_installation.html . They have all sorts of aftermarket gadgets for our Audi's that help overcome aftermarket stereo issues. I am looking at the "Enfig RWH-AUD2-HILO" as a possible solution for the low audio/factory amp problem.

A3 - USB TYPE-C to 3.5 mm jack

Hi
A bunch of new phones ditching the 3.5 mm jack and using the usb for audio. As I read, those headphones offer a better quality. I listen music on my phone somethimes 3-4 hours/day and I value quality. There are adapters to convert my 'normal' headphones to type-c. So my question is, will it work on A3? And if it does, is it even worth it? Would I get better music quality with my beloved 3.5 mm headphones and an adapter? Those things hard to come by in my region, I just wanna know if it worth the hassle?
just install viperforandroid and adjust the quality yourself.
Can I do that? It requires xposed right? Last time I checked(couple weeks ago) there was a problem with versions and I was afraid of bricking the phone.
unlook developer options (search for random tutorial on the internet) and search for "usb cofiguration" -> a3 2017 is capable of it, but i belive it wont change the sound quality. Better look for some badass headphones.

You don't need Xposed for V4A, search for Viper on this forum and you'll find a thread with a reply by me for more info. Can't post the link RN bc i'm on the go.
If you take your music listenning serious, then you should throw away this phone, buy decent headphones and usb DAC, plus have your music in lossless format, if you dont have, it is waste of time...
Ps: I advice you not to bother with install Viper4FX since it works on software level and it is just equalizer...

Very disappointed with audio. What are my options

Hey guys.
I have a Pixel 2 XL and have had it for about 6 months now.
Overall I am pretty disappointed with the audio out of the phone. I am using my Ultimate Ears TF10 through a Dragonfly Black and it sounds much worse than just the TF10s through my iPhone 6s (not using the dragonfly)
I can see a few options here and seeking some feedback.
1. Root the phone (I have read on here some custom ROMs will give better gains over USB C.
2. Get a pair of Bluetooth headphones (I don't really want to do this since I already have a good set of IEMs. Also are there any restrictions with Bluetooth such as compression etc.
3. Sell the phone and go get an LG v30 with its quad DAC.
Overall I'm pretty happy with the phone but the audio is very disappointing and I spend a few hours commuting today so it's a real let down.
Let me know what everyone thinks
Thanks guys

Root using Magisk and install the following modules.
Viper4Android FX Materialized
Ainur Sauron
Audio Compatibility Patch
Audio Modification Library
Those four modules should improve the sound quality.

Hey guys.
I have a Pixel 2 XL and have had it for about 6 months now.
Overall I am pretty disappointed with the audio out of the phone. I am using my Ultimate Ears TF10 through a Dragonfly Black and it sounds much worse than just the TF10s through my iPhone 6s (not using the dragonfly)
I can see a few options here and seeking some feedback.
1. Root the phone (I have read on here some custom ROMs will give better gains over USB C.
2. Get a pair of Bluetooth headphones (I don't really want to do this since I already have a good set of IEMs. Also are there any restrictions with Bluetooth such as compression etc.

I am surprised you are having such a bad expierience.
The USB only audio (no headset jack) advantage is that you can use better DAC/Amps than on a regular smartphone.
My measurements of the various ones out there all show pretty decent specs (with some exceptions).
The stock Google dongle is excellent (it's a custom Realtec chip), I am testing the new one this weekend. Sure, using my gain control app will get you a bit cleaner tracing but whether that's audible or not, hard to say.
Apt X bluetooth with the Mee BT adapter is also very good.
I wonder if perhaps your transducer(s) in the headphone/IEM aren't working properly. That happened to me a couple of years ago with my SE846 and it drove me nuts until I figured it out.
Another thing to check: What source are you listening to? Your own rips (and what player), Spotify, G music etc? Let me know and we can go from there, as the problems vary between each one. Do you use the on board equalizer or any equalizer? If so what gains, bands?
I just tested the new dongle and re evaluated the USB audio in Pie - the implementation is substantially better and the gains are now properly optimized.
So, I don't think your issue is a Dac dongle problem, unless it is defective.
Thanks for the help so far guys.
Source is Spotify 320 kbps.
I don't think it's the headphones as it sounds fine when I plug back into my iPhone.
I might do some more testing this afternoon when I get home as my wife has the same phone.
I also have a pair of MEE X7 Bluetooth earphones and I am more impressed with these via Bluetooth (yes they are boomy but I can tell that the Bluetooth dac isn't being restricted)
I'll fill in once I have tested on my wife's phone tonight

Considering I'm on Android 9 as we speak, yes.

I couldn't tell you were running the Pie.
Thanks!

I don't exactly advertise it. ?
I'm running those same audio mods and have no complaints with sound... Are you sure you have everything enabled in magisk property? Is V4A showing "processing =yes" when you are playing music?
My P2XL is not rooted and on Pie.
The only thing I've really missed, so far, is Dolby Atmos.
Since it's not available for Pie, I've been holding off rooting.
While searching for an audio booster, I found this app. Believe it, or not, it sounds almost as good as Dolby Atmos. I'm still tweaking it.
