Just use 3.5 to 3.5mm jack to get high ohm mode on and you will get gain you want. No need to root your phone.

I have the sony wh-1000xm3 with 47ohms. To trigger the Amp into high impedance i also plug in just the cable, wait for 10 secs then insert in hp.

Anyway, yes in high voltage mode the clarity is better after 65+ volume. But on the 70-75 my hp starts to show their limit. It only applyes to me an my hp.

Now, seriously, who can listen to more than 50+ volume more than 1 minute? ? Or with 75 more than 5 seconds? ? ? ? Maybe i should try some Pioneer hp for dj's... Expensive ones...

Anyway, LG is light years ahead in smartphone audio departament compared to sony, apple, Samsung, Nokia etc.. Now why did I write apple? ? ? ?
[LG G7 ThinQ  Themes, Apps, and Mods] Type2501:
I know I can force it into aux mode with a cable extend. But it didn't fit very well in the pocket. And it is unnecessary in the first place.

BTW, I don't root my phone because I have to change one value about AVC. I would like to mod the kernel, debloat , try custom roms and the good bits to Magisk. And you know how good LG software update is, my old v20 is still a few months behind in security update.
[LG G7 ThinQ  Themes, Apps, and Mods] redrol:
No kidding, the Dm6 gets ultra loud with the G7 in aux mode. Waaaay to loud. I am around 20-30 in that mode generally.

I have Philips fidelio x2 headphones and i dont notice any changes in audio when i turn the hifi quad dac on or off .. The audi is underwhelming compare to my cheap usb dac on computer. Dont know if its normal.
[LG G7 ThinQ  Themes, Apps, and Mods] Inerent:
Hifi quad dac is diffrent from high power impedance mode Amp. 2 diffrent things.
[LG G7 ThinQ  Themes, Apps, and Mods] ShadoV90:
[MENTION=1091275]freddy85[/MENTION], that's because your headphones have less than 50 ohm impedance. In that state amp have -15dB volume.
[LG G7 ThinQ  Themes, Apps, and Mods] freddy85:
Okey, thanks. What is the best way to force it to high impedance mode if any? i like higher volume.
[LG G7 ThinQ  Themes, Apps, and Mods] ShadoV90:
You have i think 3 options:

1. Plug an extension cable, which forces aux mode (-6dB) and next headphones. Phone will stay at aux mode.

2. Buy an impedance adapter (i think 75 ohm should be enough)

3. Unlock and root phone, and edit mixer_paths_tavil.xml then force AVC to 0 which takes off any limits to volume AND with bonus you can force CLS_H_HIFI mode in low impedance headphones. Because default option here is CLS_H_ULP which is low power mode. And HiFi Function (in tinymix) is set to off, but idk what it does.

With third option you are able to make powerful setup.
[LG G7 ThinQ  Themes, Apps, and Mods] freddy85:
But if i unplug the adapter will it stay at high impedance mode until i plugin headphones?
[LG G7 ThinQ  Themes, Apps, and Mods] ShadoV90:
I guess not. But here you can read more. It's LG V30 topic, but our phone have the same DAC, and pretty much the same "problem" with High Impedance Mode/AUX mode.

I haven't noticed better sound quality when activating the quad dac option, though i guess one would need dsd files or the like and decent headphones to notice any sound quality difference?
[LG G7 ThinQ  Themes, Apps, and Mods] Inerent:
Yes, that is correct. Dsd, mqa, hifi flacs and good headphones.
[LG G7 ThinQ  Themes, Apps, and Mods] redrol:
No that is not correct, with good cans you can clearly hear a difference in the quad dac.
[LG G7 ThinQ  Themes, Apps, and Mods] dinoc:
True, just got a pair of high impedance Soundmagic E50C, they have 50 Ohm and you can really feel the difference when you activate Hi-Fi DAC
[LG G7 ThinQ  Themes, Apps, and Mods] cesarleeds:
Hi guys

I just ordered a LG G7 Fit, i currently own this Meze 99 Classics for which i use a balanced cable, since i drive them with an Astell Kern Kann.

In order to used them with the LG G7 i will also have to include an 2.5mm to 3.5mm adapter, so my question is, will this trigger the Hi Fi DAC?

It is my understanding it should, since you guys are using 3.5mm extenders and they do the trick.
[LG G7 ThinQ  Themes, Apps, and Mods] xeizo:
Yes, any 3.5mm plug not connected to anything will trigger it
[LG G7 ThinQ  Themes, Apps, and Mods] TheDannemand:
Just to confirm what others wrote, you definitely should be able to hear the difference when toggling the HiFi Quad DAC settings. If nothing else a tiny delay.

If you don't hear that, there's probably something preventing the DAC from activating. I've seen it happen, but only once over a year ago. Restarting the phone solved it.

And it doesn't require High Impedance earphones or headphones. The main difference of those is to increase the the volume level, and maybe a slight difference in noise (that's not even certain) which nobody is likely to hear anyway, since noise is already infinitesimal in this DAC.

It doesn't require HiRes music to hear the difference either. The ESS DAC performs beautifully on CD quality 16/44 tracks. But of course make sure it's a good recording, and not a poorly compressed MP3.

And finally, be aware that unless you are using UAPP, Neutron or PowerAmp (the latter requiring particular settings) CD quality music will be up-sampled by Android, which introduces some artifacts, as described in the thread linked below.

OK, then tell me why while in dumpsys it shows 44.1/24bit packed (attachment 1) and in tinymix it shows 48/24 bit packed? (attachment 2) Why even logcat tells me that input is OK 44.1kHz but then output is set to 48kHz? (attachment 3)

Settings are ok, bit perfect was selected etc.

Creator of app tells that it completely bypasses Android audio system... but it's not. It sends audio through direct_pcm stream. (JetAudio can do it too).

Here's proof.

EDIT: Oh and one more thing. If you are using DTS:X at the same time, then it's a problem with that kind of behavior.

If input is 44.1kHz then eagle (DTS) is using tuning for 48kHz. (attachment 4)

If i set REAL 44.1kHz mix in android (you can set it via files in android) or 88.2kHz, then eagle will use tuning for 44.1kHz and output will be correct, even with Tidal.

[MENTION=8116982]ShadoV90[/MENTION]:

I go by what my ears tell me, then audio_flinger dumpsys for confirmation.

With which app are you playing?

My preferred player is UAPP. It doesn't "completely bypass the Android Audio system", since it plays with the AudioTrack API and routes music through audio_flinger. But it does manage to bypass the Mixer by converting 44/16 to 44/24 and using the offloadable flag. At least that's what my ears tell me and what audio_flinger dumpsys confirms.

This is pretty far from the topic for this thread. I mentioned the upsampling issue in my last post, but only as a side comment. The thread I linked is specifically about that, and ways to avoid upsampling -- of which I only know the apps mentioned, but would love to know about others. And even more about possible system-wide ways. I know, shameless self-promotion, but this is a topic dear to me :o

Oh, I forgot: If you're on Pie, all bets are off for now. According to reports LG messed up the audio in Pie: Depending on what you were playing just before, even HiRes music now gets re-sampled (which wasn't the case on Nougat and Oreo). UAPP has a solution in the works. See the link at the end of the up-sampling thread,
[LG G7 ThinQ  Themes, Apps, and Mods] ShadoV90:
As you can see with icon on screenshots, i used UAPP.

I'm on Pie, but the same was on oreo. What's messed up, it's just loading stock files before magisk works. You can "fix" this by typing in terminal:

su -c killall audiiserver

And all files will be loaded again if you changed something.

What your ears tells you it's just placebo effect sir.

I don't want attack you or anyone, just what i believe isn't just ears, but proofs as well and i give 3 proofs that UAPP don't work like it's intended.

Btw i have system wise solution for avoiding resampling. I mean resampling by not integer count.

You can force deep buffer output for headphones and primary output for speaker Set sampling rate to 44100 or 88200 and 16/24_packed/32 bit and voila. 44100Hz tuning and double of that output. This will avoid that artifacts. Because resampling by adding 0 to every second sample is way more safe.

I will add screenshots later, because now i am at work.

With regards :)

ShadoV

EDIT: as you see with that kind of operation you can set anything you want :)

You can set even 192000Hz :D

EDIT2: I forgot. I used Tidal this time.

[MENTION=8116982]ShadoV90[/MENTION]:

Oh, I have tons of test outputs to confirm what my ears tell me. As I wrote, while I trust my ears, I don't ONLY trust them. I've been working with other head-fi members on this for a long time, as you will see if you care to check the links I gave you.

Once again, I am deeply interested in what you have to share about sample rates, but I will NOT engage that discussion in this thread, where it is far beyond the thread topic and clearly beyond the interest of other participants. Surely you must have noticed that nobody else engaged your previous posts in this thread, despite their useful content. In me you found a taker, just not here.

If you respond in the thread I linked -- or create a new thread about sample rates, if you prefer -- I will be very happy to engage that discussion.

BTW, I am on V30 which doesn't have Pie yet. And personally I am not updating until the audio situation has settled on Pie. We assume it's the same between V30 and G7, but there are significant differences in the kernel structure and the ESS driver between V30 and G7/V35/V40 etc, so it is possible that some things are really not the same. But again, beyond the discussion for this thread.

A note of clarification to what has previously been posted here: AVC has nothing to do with Automatic Volume Control. It is Analog Volume Control (as opposed to digital) and refers to the OpAmp component of the ESS DAC. This amp is an integrated part of the DAC, not a separate component engaged only in High Impedance mode (as was suggested earlier in this thread). And the DAC has two (not three) amplification modes triggered by its driver depending on impedance of the plugged in headset/earset: HifiOne (<50ohms) outputting 1Vrms and HifiTwo (>50ohms) outputting 2Vrms. Aux mode (>600ohms) is a hybrid mode implemented by the driver, which uses HifiOne combined with AVC settings to increase volume when connected to an external amp.

Enough, I'll get carried away :o
[LG G7 ThinQ  Themes, Apps, and Mods] Zoki88:
So if we want to change, for example, to AUX mode, we change not only AVC, we must change two things: AVC AND headset type, and for AUX it would be AVC 6-7, and headset type 3, right? 2 is for high impedance mode, and 1 is normal mode(strange order). If that's true, then what is Master Volume used for?
[LG G7 ThinQ  Themes, Apps, and Mods] ShadoV90:
The only thing you must edit is AVC Volume. Aux mode or High Impedance Mode have just higher (in that file lower) value of analog volume. Mode is set when G7 "see" impedance of headphones.

Setting Master Volume value higher will cause quieter audio.

Setting Headset type will give you nothing. When i plugged in 56 ohm headphones (type 2), it will trigger HIM no matter what i write to headset type.

Remember, headset type is there because of their avc volume.

Something important: in default state, every "normal" file will be played in 16 bit and higher avc on sensitive headphones will cause hissing/static noise.

If you trigger playing in 24_3LE (24 bit packed) or 32 bit mode via some players like UAPP OR proper edits in some files, you will be able to get no noise and louder output when you change AVC.
[LG G7 ThinQ  Themes, Apps, and Mods] Zoki88:
Thanks a lot, just one more question: i suppose that where i have to change that AVC volume depends on which type of device i plugged in (normal, aux), for example do i change avc in <path name="headphones-hifi-dac"> or in <path name="headphones-hifi-dac-aux"> or in <path name="headphones-hifi-dac-44.1-aux"> etc, right? Or i change for any type of device in same path (first one)?
[LG G7 ThinQ  Themes, Apps, and Mods] ShadoV90:
<path name="headphones-hifi-dac"> covers most situations for low impedance headphones.

<path name="headphones-hifi-dac-aux"> covers most situations for aux device and so on.

So if you will change AVC volume here it will be fine.

But if you want to be sure that your change will cover all situations, then change AVC for proper headset type.

You can experiment with that, but be careful, change only value numbers here, because if you will change something in name, or delete one character too much, you will end with endless boot screen or no sound via headphones.

[LG G7 ThinQ  Themes, Apps, and Mods] ShadoV90:
I assume that you have v40 with pie.

If you changed avc and nothing happen, then maybe lg does the same thing as in g7 pie.

Try to install material terminal (or if you have any then ok), plug headphones and type (while not listening anything through headphones) su-c killall audioserver

When you do that, then write here if any change occurs (or not).

Can you send file which you edited?

I want check few things.

And which method of root you have? Magisk or something else?

If Magisk then do you have AML installed?

IDK if you know or not, but AML (Audio Modification Library) is module for Magisk and it is necessary because edited files will be overwrite with default files after reboot or you will be not allowed to edit.
[LG G7 ThinQ  Themes, Apps, and Mods] gaurav_15:
Edited mixer_paths_tavil.xml.. I have magisk but I haven't installed aml.. Should I install it first n edit the mixer_paths_tavil.xml later?
[LG G7 ThinQ  Themes, Apps, and Mods] ShadoV90:
Yes. Exactly. First install AML and next edit your mixer_paths_tavil.xml. After reboot you should have louder audio. If not, try that killall option, then write pls if you are successful or not :)

[LG G7 ThinQ  Themes, Apps, and Mods] ShadoV90:
Last question. Plug in your headphones. Run terminal app and type su -c tinymix.

Search for ES9018 AVC Volume and tell me which value do you see.

If 0, then this is max power of amp. If 15 then for some reason modification didn't occur.

Somewhere in tinymix (half bottom) you should see something like what is in screenshot.
[LG G7 ThinQ  Themes, Apps, and Mods] gaurav_15:
It's showing 14 for avc volume..
[LG G7 ThinQ  Themes, Apps, and Mods] ShadoV90:
In my mixer_paths_tavil.xml avc value of 14 is for headphones-hifi-dac-44.1

IDK how it's in your phone. In LG V30 value of 14 is in every case of low impedance headphones.

So, try change value to 0 in "headphones-hifi-dac-44.1"or in every avc volume.

Maybe that will help.
[LG G7 ThinQ  Themes, Apps, and Mods] gaurav_15:
I have changed avc value to 0 in mixerpaths but still in terminal it shows 14..
[LG G7 ThinQ  Themes, Apps, and Mods] ShadoV90:
Then i'm sorry. I can't help you. Something must be wrong.

I don't have LG V40 and i can't check what's going on.

These methods should work. But i don't know how V40 is working in this matter.

Maybe somewhere is second mixer paths tavil, and android is checking this file instead right one in vendor/etc... i don't know.

I will ask UltraM8, creator of Ainur Audio mod, maybe he can solve your problem. You can try to install Ainur Sauron mod. It have proper modifications in mixer_paths_tavil.xml as well as other modifications in audio. Try that, maybe this mod will help you.
[LG G7 ThinQ  Themes, Apps, and Mods] FluffyDiscord:
So what kind of setup do I need to get to have bit perfec source > player > dac&amp > headphones (is it possible with poweramp even ?)? Can you make like a summary of modifications needed for Pie G7 ?
[LG G7 ThinQ  Themes, Apps, and Mods] ShadoV90:
To have a bit perfect playback in LG G7, you need just an application which supports direct playback. Direct playback is always bit perfect.

Problem is when you are turn on DTS:X because it use different tunings (44.1 kHz and 48 kHz), and it depends on which sample rate is using. During direct playback 44.1 kHz in tinymix i see 48 kHz and DTS is using that higher samplerate tuning. This is mostly inaudible, but can cause effect that sound is "better" :D with punchier bass etc. than with source 48 kHz. But if you are purist then you will not use DTS at all :)

AFAIK Jet Audio plus, USB Audio Player PRO have these properties. Probably Poweramp, Neutron etc. too.

I don't know how it's with Tidal, because i am using "high" bitrate option. I didn't buy HIFI nor master. And with normal and high setup app is using compressed audio offload which is similar to direct output, but with compressed files like mp3, aac etc.

BTW. even with high option i see that there are some songs with *TADAAA* 22050 kHz sample rate and it automatically sets to normal for that songs :D

Audio mods

for LG G7

are mostly focused on forcing high analog gain for low impedance headphones.
[LG G7 ThinQ  Themes, Apps, and Mods] FluffyDiscord:
Yeah I dislike DTS:x, it destroys the audio, the effects are too strong. So no audio_policy changes needed then. Alrighty

If you are interested in hifi sound have you considered rooting & installing viper4android? What are your thoughts on viper. I'm going to root my lg g7 hopefully but not until I have every step in correct order and nothing left out (in my mind). Once I am confident and root do you think viper4android would be an asset to an already, redy to go hifi capable phone? I ask because viper has given me greater volume and sound quality on my other phones. 99% of play store apps lower the volume greatly as you increase bass/treble. I like my eq sliders in a U curve as I'm a hip hop head & love bass and treble high but without the volume dropping. With viper you can increase bass/treble greatly & even get louder volume after doing so, why can't other eq developers achieve this?
[LG G7 ThinQ  Themes, Apps, and Mods] FluffyDiscord:
Hi, first of all, there is nothing "HiFi" about viper4android. The opposite, you may say, as it forces 16/48 mode and may add unwanted sound color or even low white noise. Louder sound does not mean higher quality, that's a simple illusion.

I have had viper4android since Android 4 on many devices and I loved it, but back then, Android audio was ****, my audio files were ****ty mp3s, and my on ears were cheapos for 10 bucks, so I had to help myself. Now, thought, as I got better files (flac rips or decent opus files) and in ears (tin audio t2), any EQs are irrelevant, as these in ears have pretty clean sound and I can adjust the fine details in my Poweramp player (I am tuning 4kHz down by 1.5db). With this setup I have the exact audio I like for my ears. No need to other DSP units.

Back to the discussion, I think something is wrong with your settings, as my G7 can drive 250ohm dt990 pro just fine. Now then, I am rooted and so far I have tried only jamesdsp, which does not work at all. Stock rom is limited with audio modding. You will loose the stock's clean sound after flashing custom rom and you will be locked to 16/48. If this does not bother you, then go ahead.

SUMMARY: The hardware increases the quality dramatically, rather than software. I don't know your listening device - over ear, in ear, Bluetooth something, but to increase your enjoyment, search for something with U signature ( I myself love V), something more expensive and try that, also try to get proper audio files (or decent rips).
[LG G7 ThinQ  Themes, Apps, and Mods] TWiiTCH:
Yeah when I really think about it you are right I admit it. In highschool my buddy had 2 JL audio 12 inch competition subwoofers in his car with a box holding around 4 to 4.5 cubic inches of space in it. He ran the subs at 1ohm mono with a 14,000 watt amp and I got used to feeling the music. I guess I miss that and those days.

You made a great point that viper would limit me to 48khz and 16bits. I last used it on my Nexus 5 and have it on my android tv box rigged to stream to my stereo and I love the warm lows from tight kick drums to 808 bass booms that actually rattle the house. I overdo the db volume and bass but I love it. I'll finish by saying you convinced me to stay stock. Having the possibility of 96khz and 32bits I think it is, heck even 24bits is good. No need to put a leash on what a good set of headphones on this phone could do for me. Right now I'm using beats EP on or basically over ear headphones. They were 129.99 here in Canada when I bought 2vweeks ago.

https://www.cnet.com/products/beats-ep/specs/

I found out when I got home they were designed for iPhone but the work great. Only 1 issue, gotta use mechanical vol + - on phone. Mic works and can change songs with ? cord too. Right now I'm running poweramp & getting a 4 out of 5 for sound. AAC in m4a format at 128kbps. Step up the recording they'd be real sweet. Thanks again! ✌️

I'm out now, just had to share details. I'm OCD for real, pretty bad. Sorry.
[LG G7 ThinQ  Themes, Apps, and Mods] FluffyDiscord:
Beats are warm and bassy, not much of a U shape. But heck, if it's the sound you are satisfied with.

Since we're on the topic and I've been up all night trying to get viper4android onto my LG G7 which luckily I didn't succeed now that I have being given the knowledge behind the inner workings I just wanted to share with you all the top three apps I like, does not mean you have to by any means, but the ones I like and use the most are in this photo with number one ranking at the top and the bottom is my third choice. I think Power Amp has always been my go-to and it was my first audio that actually made me feel like phones would eventually sound better and better and gave me some hope so it's my go-to tried-and-true. Second of all is jetaudio, and if you'll notice under the logo there is something about 32 bit sound engine but I don't know what difference it makes or how quality and refined they have made it so far but I threw it in so people could see it's there in the settings if you want to look for it and give it a try. And last of all is Onkyo HD or hi-fi music player. It's a pretty basic application but the equalizer and whatever they have done under the hood has given it a big place in my heart and I always switch back and forth from all three of these with power amp getting the most play time and the other two are about 50 50. Are there any other Audio Apps out there since I found these ones a few years ago that I might be missing out on in terms of sound and functionality and all around dedication by the Developers squeezing out every bit of performance in their app that anybody could recommend to me? If so just give me a shout because I love talking audio and will join in whenever possible. I'm usually on XDA once daily minimum so I will keep an eye out four interesting recommendations and I will test every one of them. There seems to be more and more popping up but it's the quality of sound that doesn't seem to be changing.
