[LG V20 Questions & Answers] dartinbout:
Hi all,

The amount of dis-information being spread about the DAC is a dis-service to the efforts LG has made to provide us with a way to record and listen to hi-res music. I understand if you have a model, from a carrier. that didn't include the app, or you don't have any actual high resolution music to test, or a pair headphones that have an impedance lower then 50-600 ohms. Your complaint should be with your carrier, not the engineering that went into this.

To stress this further, you need 3 things to take advantage of this ability. The LG "Music" app, known hi-res files, DSF, WAV's FLACS of 24\96 and above and most importantly, a set of cans that will trigger the 4 way DAC.

As noted but the LG engineer that is quoted here.

The Quad DAC’s low power mode shuts down three of the four DACs when they’re not needed, to increase battery life when playing lower quality audio or using lower quality "headsets. – Ken Hong, global communications director for LG"

http://www.androidauthority.com/lg-v...lained-713587/

I have used the HD recorder extensively, in the last few weeks. Live music, recorded at 24\192 plays back on the phone at 24\192 and when transferred to my pc, with a soundcard that outputs 24\192, it identifies it as a 24\192 track. No other music application, that I've installed, will play back the recorded music, on the phone other then either the HD Recorder or "Music" at that rate.

The next person to claim the phone is throttled, should document those 3 elements before any more of such nonsense should be promulgated.

This phone is really spectacular and after making full use of it's abilities, I've grown tired of these unfounded allegations.
[LG V20 Questions & Answers] hykhleif:
so why don't you graciously show us that you can play high res 192/24 without down sampling before shooting such a long answer. Unless you want us to blindly just believe what you wrote.

This in my books deserves a law suit against LG and can be easily won, as false advertising is a big slam to the main selling point of this phone

I use high end iems called empire ears zeus R, also sennheiser ie800, and a full size headphone Oppo Pm1, so please do not try to show off by saying what iems or headphones we are using. My iems zeus r alone cost 2100 USD and the Oppo Pm1 is a very expensive palnnar headphone as well

also I know how to trigger the hifi quad dac by plugging in a cable adapter first and I check in the settings that shows an external source hass been connected but simply everything gets downsampled, and I use high res files 192/24 and dsd files
[LG V20 Questions & Answers] charlie.s:
Thanks for an informative post. I don't quite understand why technical information about the design of the V20 is so hard to find. I am not faulting LG alone as few if any OEMs bother to back up their sales claims with hard facts and well-reasoned academic discussions. Why don't we see any white papers prepared by the engineers who are responsible for designing improvements in sound reproduction and for that matter, just about any other "ground-breaking" advances?

Instead, we see string after string of comments by anonymous users and outside "experts" and it is impossible to separate fact from fancy. It is frustrating.
[LG V20 Questions & Answers] Emerald Core:
Thats why not to believe anything written in here nor on any review site.

As head-fi ancient forumers always say, use your ears to decide.
[LG V20 Questions & Answers] mlknez:
The LG V20 has an extra DAC chip called the Sabre ES9218. Here is a fact sheet about that DAC:

http://www.esstech.com/index.php/en...udiophile-features-mobile-devices-first-time/

---------- Post added at 04:49 PM ---------- Previous post was at 04:47 PM ----------

I submitted my testing results to LG and they were able to reproduce. They are in concurrence and are looking for a firmware solution. This was difficult as I don't speak Korean well.
[LG V20 Questions & Answers] charlie.s:
I appreciate your contacting LG in all of our behalves and I also appreciate that they are willing to work with you towards a solution. You might wish to point out to them that a whitepaper outlining the means in which the ESS chip is interfaced to the V20 (both hardware and software) would be real helpful. While a datasheet from ESS is informative, it is a far cry from explaining the behavior of the entire audio system when, for example, high impedance earphones are connected.

There is too much smoke and mirrors involved in this industry. Thank heavens for places like XDA to cut through the b.s., though it would sure be welcome to hear the cold facts straight from the engineers.
[LG V20 Questions & Answers] mlknez:
The big question is how they were able to miss such a huge problem and how none of the carriers nor any of the the reviewers caught it.
[LG V20 Questions & Answers] justthefacts:
All I know is that no other phone has sounded this good plying MP3 music through the aux cable in my car
[LG V20 Questions & Answers] mlknez:
I have no doubt that your mp3 files sound better on this DAC than any other you have tried. Just like I'm sure that driving a Lamborghini at 60 mph feels great also.
[LG V20 Questions & Answers] @rbiter:
Lmao.
[LG V20 Questions & Answers] dragion:
Thank you for "your" thoughts on this issue.

I would like to know is it possible to advise me how to see if the stock music player on the V20 show the output of the audio on the V20...especially 24/192 tracks.

According to my post with PowerAMP Alpha 704, the V20 is actually "down sampling" the audio to 48 kHz.

I'm able to see this via the information displayed from the app.

The question now is if PowerAMP Alpha is the better player compared to the stock Music player on the LG V20?

I know this was true coming from the V10.

The above question can be addressed by anyone who has any information about this...thank you.
[LG V20 Questions & Answers] mlknez:
The part of the phone that records audio is the analog to digital converter (ADC) NOT the digital to analog converter (DAC).
[LG V20 Questions & Answers] midmadn:
What do us Sprint owners do? We didn't get a music app other than google play music, amazon music and sprint music zone. Can the LG music app be downloaded anywhere?

Thanks, Jack
[LG V20 Questions & Answers] dartinbout:
Power Amp's forum's are filled with requests to support the DAC in this phone. The Alpha worked for the DAC in the Note 7 and S7 Edge. The LG Music app is not sophisticated enough beyond identifying the properties of the file being played. I don't see a log file anywhere.

As an experiment, get a high impedance headphone (50-600 OHM's), play a high res file of a song. you know well. Listen to it in Power Amp and then LG Music. If the most sensitive testing device you have doesn't make you cream in your jeans when you hear it through LG Music, I'm not sure what else to tell you. Use your ears.

As for documenting, it beyond that, all I have to test this is my custom Auzentech Sound cards' line in, and it identify's it as High Res and sounds exactly like it when played from my RAID.
[LG V20 Questions & Answers] Koont:
Any of you guys tried LGs Music Flow Player? To me, it sounds better them the others. You can get it on Smartworld.
[LG V20 Questions & Answers] jagwap:
I'm going to follow with interest. This is going to run and run, until someone plays a > 24kHz tone out of the headphone socket.

By the way, I know of plenty of so called high end networked speakers from hi end brands that will play back your hi-rez files, after resampling them all to 48 or 44.1kHz. It isn't uncommon.
[LG V20 Questions & Answers] mlknez:
It's not any good.
[LG V20 Questions & Answers] robroy90:
What does one need to get in order to fully leverage the DAC? Is there a set of reasonably priced over ear cans that will enable it? What should I be looking for? Will a mini-jack to RCA cable work for connection to a stereo, etc?
[LG V20 Questions & Answers] mlknez:
At this point in time, you cannot FULLY leverage the DAC until LG fixes their firmware issue. However, There are 3 things to go into quality sound:

1. High quality recordings (you have heard of garbage in - garbage out. It is very true here)

2. High quality DAC (you have an excellent one in the V20)

3. High quality speakers (external boxes, headphones, earphones, etc.)

Don't worry about impedance here unless you get a very hard to drive headphone (usually above $1,000). Your music taste will dictate what headphone will make you the happiest. Audition a lot of them. If you are really about recreating the recording the most authentic way possible, make sure that you get headphones that don't emphasize a certain frequency range at the expense of others. Make sure that they cover the range of human hearing or better (20hz - 20khz). Make sure that they fit well and are comfortable.

A 3.5mm stereo plug to 2 RCA plug adapter/cable will allow you to plug this device into a stereo that has RCA inputs You could also use a 3.5mm Male to 3.5mm Male stereo plug to plug it into any speaker system that takes an analog 3.5mm plug for input.
[LG V20 Questions & Answers] robroy90:
Thank you. I appreciate the info. I just wanted to make sure I didn't need headphones with feature "X" or audio player app "Y" to take advantage. I guess we wait for a firmware update in the meantime?
[LG V20 Questions & Answers] midmadn:
I tried that. It won't load unless it detects a wireless music flow device. It's like a whole home music thing. It's not just a straight up music app.
[LG V20 Questions & Answers] Oyeve:
The DAC in the V20, IMO, is crap. I barely hear much of a difference regardless of what player I use. I find, again, IMO, the V10 DAC much better. Much more of an impact that the V20.
[LG V20 Questions & Answers] mlknez:
The DAC in the V20 is better, but you need to have a quality music file and quality speakers to notice the difference.
[LG V20 Questions & Answers] @rbiter:
Yeah. Definitely try on your surround or home stereo. These sound awesome with my onkyo 3009, parasound halo amplifier and RBH speakers. Smoother than my BD COPs and DT770 pros.
[LG V20 Questions & Answers] Koont:
You have to hit the menu button, top left corner. Select "my phone" and bam. There's your music player.
[LG V20 Questions & Answers] Oyeve:
I downloaded the DAC fix for the V10 on the V20 and noticed a much better improvement. Strange that the builtin DAC switch doesn't do this. I use PowerAmp (beta) and the V10 fix works great. So, my opinion has changed. The V20 DAC is great, the LG implementation stinks.
[LG V20 Questions & Answers] mlknez:
I believe, that all you are doing is turning on high-gain mode.
[LG V20 Questions & Answers] Oyeve:
Probably. I gave up on it anyway as I always use my fiio amp and get good results without dac sw switches. I just wish it was consistent. Goes from normal device to external device to high/low impedance with every plug in and unplug.
[LG V20 Questions & Answers] midmadn:
The quad dac definitely works with Neutron using Beats Studio headphones.
[LG V20 Questions & Answers] mlknez:
Of course it works! Your Ferrari will also work if you only want to go 70mph, but some people would be unhappy if it didn't go any faster. Those people content with driving the speed limit on standard roads won't notice any difference either, right?
[LG V20 Questions & Answers] midmadn:
I'm confused. Is this the long version of Beats suck?
[LG V20 Questions & Answers] PsiPhiDan:
No, he's mad that LG has limited the capability of the DAC. While great, it's not at its peak ability due to firmware issues. It's like a Ferrari that cannot get to full speed, but it's still an enjoyable ride.

As a side note, Beats don't suck but are massively overpriced for what you get. I also don't like the heavy emphasis on bass but that's personal preference. :)
[LG V20 Questions & Answers] jagwap:
I agree with your personal preference on bass emphasis.

Continuing the analogy: emphasised bass is like 1970's American saloon suspension on a Ferrari. It may be fun but it's not right, tight or correct.
[LG V20 Questions & Answers] mlknez:
Smart Post!
[LG V20 Questions & Answers] Get Ur Noob On:
So LG could fix this with a simple patch? Also does anyone know if gonemad music player utilizes the dac or not? Shouldn't apps like Gmmp and poweramp bypass the android audio engine and therefore not downsample?

Sellers only shipping locally for now. In case y'all don't know g market is an online web market in Korea and they're legit. Got some hard to get Samsung accessories from there and only had to pay a small premium. I just want one whole kit with the cradle and like a 6 pack of batteries. Ugh.
[LG V20 Accessories] MidwestDrummer:
You can be the kit easily on eBay from Korean sellers.
[LG V20 Accessories] @rbiter:
What do I need 6 cradles for and the would be around $400. I want one whole kit and some legit batteries which I'm sure will sell for $20-30 when LG gets their act together.
[LG V20 Accessories] prinzhernan:
I'm asking my friend in Korea to look for it but the LG shops are saying they are out of stock? WTF?
[LG V20 Accessories] wing_addict_usa:
Resell for a profit
[LG V20 Accessories] @rbiter:
Hustlers are buying them all up and selling to other regions. LG needs to step up their battery manufacturing anyways. They make excellent batteries and now Samsung has contracted them for future phones. In The meantime they need to step on it and get some on their website for the USA region. Why release a flagship phone with a removable battery which is getting more and more scarce these days and PROFIT. I know LG aint hurting that bad for money but they definitely need to step up the profits in the mi ile division.
[LG V20 Accessories] @rbiter:
The hustlers are buying all the stock and getting the jump on it to make a few bucks.
[LG V20 Accessories] kms108:
Have you tried www.ebay.co.kr they have a few, it's a shame that I can't send batteries out of hong kong, we have them readily available at USD 30
[LG V20 Accessories] prinzhernan:
That's so sad. My only hope are friends coming from Hong Kong now since my friend who just flew back from Korea said that he went to 4 shops and all were out of stock.
[LG V20 Accessories] CHH2:
Saw the kit on Amazon yesterday for $68-69 but decided to wait and see if it gets cheaper.

I was able to buy it on eBay on Oct 17, for $57 from a Korean vendor. Came FedEx on the 19th, OEM part no issues...

Sent from a TMo V20
[LG V20 Accessories] kms108:
so have you checked out www.ebay.co.kr
[LG V20 Accessories] prinzhernan:
I have but unfortunately they can't ship batteries from Korea to my country because of safety concerns.
[LG V20 Accessories] kms108:
Which country is that

---------- Post added at 05:51 PM ---------- Previous post was at 05:39 PM ----------

If i'm guess correctly, you are from Philippines, there is a seller on ebay korea who ship to Philippines free of charge. the cost is USD 55.5
[LG V20 Accessories] prinzhernan:
I actually tried 3 sellers and they ended up refunding because they can't ship batteries due to restrictions I guess the whole note 7 thing. My dad had an extra Xiaomi battery shipped a few months ago with no problem. Gah stupid Samsung.
[LG V20 Accessories] kms108:
Ill check out if china allows shipping out batteries, may be I can help out.
[LG V20 Accessories] prinzhernan:
Oh that sounds great thanks!
[LG V20 Accessories] kms108:
Can't help you with this either, china has also stopped sending batteries. you're out of lucky, looks like you will have to wait at your end, in your country, don't you get two batteries.
[LG V20 Accessories] @rbiter:
So how is China shipping phones to other countries? They allowing corporations with permits or something? And is too risky personally to try and dupe the system?
[LG V20 Accessories] kms108:
Shipping batteries as a end user is not possible, but as a corporation, they have a license to do so. In hong kong you have to submit the battery to EMSD (government body) to test and if safe to do so, they will issue a safety report.
[LG V20 Accessories] prinzhernan:
It's all good. Thanks for trying!
[LG V20 Accessories] @rbiter:
No it's not. I was trying to him as an international smuggler. You're ruining my chances. Ugh.

Jk. Thanks kms. Happen to know any other reputable online retailers from Korea by chance? I came across g market by chance around galaxy nexus and note 2 days.
[LG V20 Accessories] kms108:
You can send this place a link from any shop or auction and see if they can make the purchase, there service isn't very expensive, and I have used them before for stuff I cannot buy.

http://www.avecko.com/buying-service/about-buying-service/

This place has them, they ship international and have the battery, seems cheap.

Works great on TyTN with 6GB SDHC and WM6

At first it gave me a "Unknown Device" on Windows-XP

-> menu ->troubleshooting -> Disable RNDIS on Active

Problem fixed ;-)

Then it gave me CRC-errors while copying

-> menu ->troubleshooting -> Disable concurrency

Problem fixed ;-)

Now it works, not only on my desktop-pc but also on my mediaplayer (external USB drive with TV-connection).

Hello all, I'm trying to get into kernel development for personal use (at the moment :D). Currently, the kernel boots and has the features I currently wish for it to have (and it actually performs amazingly well!), but it won't connect to the camera for whatever reason. I know it's an issue with "my" kernel because I restored the stock one, and the camera opened up just fine.

Below I've provided some links to help with diagnosis. Although I am looking into this myself, I'd appreciate some crowd sourced help with this!

Yes, I know I'm running Flyme, and a beta version of it at that. Yes, I understand there's going to be issues since it's a highly modified OEM ROM. I also admit I'm a bit of a noob when it comes to this and that I have very little coding experience with C (other than C#, which doesn't apply to this situation). But I'm looking at this as a personal learning project, and I hope to get some insight on how to fix these sorts of issues in the future on my own!
[Google Pixel XL Questions & Answers] johnciaccio:
I have had the Pixel XL for a week now and I have found some interesting features not scene on Android 7.0 on my Nexus 6. Mostly related to Project FI I think although there was more here are two that I can think of.

1. Project FI app asks if it can test and optimize my cell signal.

This took about 5 minutes.

2. Google Connectivity Service (Wifi Assistant) asks if I would like to protect this connection?

I was using public wifi at Walmart. After saying yes it took about 30 seconds for the VPN key symbol to show up.

None of this happened on my N6 or my wife's. Both on latest update.

I know there was more but what I can remember right now.

If anyone has noticed others please let us know!
