maybe you should try and see which one you like the most. I think that the DAC is used on other roms. But depending on your headsets you might or might not really notice. for example a low impedance headphone will be benefitted by the DAC as it has lower noise

I'm not sure what the difference is between Qualcomm DAC and "hi-fi" DAC. My guess is whatever the case is, you're getting a lesser quality audio experience with anything that isn't stock, especially as there is media distortion on the AOSP ROMs.

Also, understand that a DAC is a hardware feature. This isn't something "developers" are touching and the incompatibility experienced is because of the software support, or lack thereof.

I would ask this question in the ROM thread, I'm sure the owner of your ROM would have more to add.
[ZTE Axon 7 Questions & Answers] pinkywinky:
Thanks! I had a feeling it was, but the mixed answers were bugging me so I had to make sure. And I do have decent headphones, its just wouldnt be easy to do an A/B comparison without the switch.

You could just use AINUR SAURON. I belive it forces use of the HiFi DAC by default with modded drivers.
[ZTE Axon 7 Questions & Answers] Choose an username...:
how can it do that, if it's not a device-specific mod? If the DAC is not coded into the device itself i guess you won't be able to use it since it has no driver

No, it does not.

Yet...

---------- Post added at 06:24 PM ---------- Previous post was at 05:53 PM ----------

Just to provide you a clear answer on this, because it seems to be missing in the responses:

No, you are not utilizing the full sounds potential if either of the following are true...

1. You are not using low-impedance, high-quality headphones.

2. You are not streaming high-quality media (pandora streams at 192 kbps, if I remember correctly... not really considered HQ, even though pandora's settings indicate such)

3. You are using a custom ROM based on Lineage or any other AOSP-based software, unless one of these ROM compilers have built their own drivers and integrated software to make use of the DAC hardware.

Understanding how a DAC works is critical. It is hardware, which requires firmware support, which requires software support.

You simply won't get the same sound quality/output that you see with the stock music player and a high quality mp3 or FLAC file.

If most of the music you listen to is streamed, or you are connecting via bluetooth, I wouldn't worry so much about it.
[ZTE Axon 7 Questions & Answers] LazerL0rd:
It recognises ur device in a special installer and then patches the driver config to tell it which DAC and soundcard to use.

---------- Post added at 10:20 AM ---------- Previous post was at 10:18 AM ----------

It does actually. That's just a different mod to remove ALL software effects and go straight to the DAC or Hexagon DSP.

SAURON does the default software effects (maybe optimised I think) then runs it to the HiFi DAC of the device being used. For ALL applicaions and ALL sound. IT configures the alsa config file (which inturn the ALSA driver uses) to use the correct soundcard and correct DAC that the installer finds.
[ZTE Axon 7 Questions & Answers] pinkywinky:
No I definitely agree. But we do never use the Qualcomm DAC. We have 2 akm das, and the issue is what one of them they use. The Qualcomm DAC isn't even wired in our phone
[ZTE Axon 7 Questions & Answers] pinkywinky:
So, you are right and wrong. Our phone does not use the alsa configs at all. However, apparently someone worked with the guy who makes SAURON, and set it up so it routed the audio through the the encrypted files that ZTE gave the rom makers for audio. But you do have to use the be Alta versions found on their messing in app (should be a link in the post). Our phone supposedly works with SAURON since beta 4, but not yet in the official. It may have some effect, but not what you think it does
[ZTE Axon 7 Questions & Answers] pinkywinky:
Well I wasn't really asking anything. It's pretty a known point with our device. ZTE did not handle unlocked bootloaders well, and a lot of our audio level is encrypted, which I believe is due to the Dolby hardware we have present. But all in all, our device performs fantiasticly audio wise, despite the few hiccups
[ZTE Axon 7 Questions & Answers] Choose an username...:
Nope, not like that. We have the Snapdragon DAC, the AKM DAC, and the AKM ADC. The ADC converts analog signals to digital (microphone).

You can either use the Snapdragon DAC or the AKM DAC.

The switch on stock lets you use the AKM DAC or the SD DAC (lower power consumption, it seems). It CAN get to 192KHz seemingly since Poweramp detects it as Snapdragon 24-bit PCM, and it really DOES sound better with the Samsung UHQA hack, but there's nothing proven really.

On the other hand, the AKM DAC is there, it can be selected while using Poweramp, and I believe it has more soundstage and more defined bass. But on stock the UHQA hack will simply enable the SD DAC.

Now there's one thing that I'm not sure about. You know how there's a zip to force the use of the AKM DAC on LOS based ROMs. Well, it works. Now the thing is that I tried the UHQA hack here... The equalizer is sort of much more responsive, dunno about that. But it seems to be outputting at 192KHz as Poweramp says so. And this is definitely the AKM DAC, not the SD DAC as it would happen on stock. Thing is, I can't really hear much of a difference

I used HD360 Pros, they use the 380 Pro drivers which are 32 ohm. Not too low but there is still a huge difference in the highs with the SD DAC.

I'd like anyone with hifi headphones to try the same (LOS + AK4490 patch + Samsung UHQA hack + Poweramp 704). I think it's the closest we'll be to 192KHz on the AKM DAC outside of the stock player, what with MaxMP taking more than half a year to update the GUI of Poweramp lol

[MENTION=7372544]warBeard_actual[/MENTION] Am I wrong on anything? I have zero knowledge on the inner workings, all of this is basically empirical
[ZTE Axon 7 Questions & Answers] Choose an username...:
[MENTION=8260867]pinkywinky[/MENTION] Update, I just found out that the Ak4490 patch + UHQA hack somehow manages to route sound through Viper4ARISE. That's why I had to lower the bass sliders a lot. Disabling Viper actually improves the sound quality some, but I'm still not 100% sure that it's 192KHz
[ZTE Axon 7 Questions & Answers] RobboW:
Maybe try uninstalling ViPER driver and turn off ViPER?

Have you had a play with Jet Audio yet?

Use the AM3D plugin and don't need EQ turned on. Sounds fantastic. Great soundstage, has a warmth Viper lacks and manages a great punchy bass line.

With the sound I'm getting, debloat of system is the only real use I have for root so it's still locked up fully.
[ZTE Axon 7 Questions & Answers] Choose an username...:
You sure that AM3D actually processes at 192KHz? That's like the whole point of the UHQA hack and the huge FLAC files. For example Viper says that it processes at 48k

Plus I've never been able to make AM3D work, i've read somewhere that it only works in Marshmallow?
[ZTE Axon 7 Questions & Answers] RobboW:
I don't have any files like that to test with, that's why I asked.

The plugin works fine, you can trial it and see if it works for you. Don't have to pay straight away. Remember to turn on the 32 bit processor in settings.
[ZTE Axon 7 Questions & Answers] joaste:
Not sure this helps, but you can get hi-res audio files for testing from here.
[ZTE Axon 7 Questions & Answers] pinkywinky:
So unfortunately you are almost right. But our phone NEVER uses the Samsung DAC. So we have 2 dacs, the hifi one which is the AKM 4961, and the non-hifi one(which runs the speakers and the audio output for the switch that's not hifi in stock, the AKM 4490). Our phone is actually not at all wired for the DAC off of the cpu, ZTE actually bypassed the stock Android version of audio. There are actually encrypted files (unfortunately due to us having Dolby hardware). All of the roms actually had to work with ZTE in order to get audio to work.

So in other words, if the audio upgrade does not involve those file, it does nothing
[ZTE Axon 7 Questions & Answers] pinkywinky:
So if we do our phone correctly, we should need no software. If you like the sound than all on you, but unfortunately all you are doing is possessing **** with our coupon. But yea viper sucks, it limits audio to 44.1khz. It can't do any more. Viper is a **** hole for good audio
[ZTE Axon 7 Questions & Answers] Choose an username...:
The AK4961 is an ADC, NOT A DAC! What makes you think that ZTE added another crappier DAC for the speakers?

The AK4490EN is the DAC our phone uses, as stated in Asahi Kasei's own website. It is a low-power QFN package chip designed after the AK4490EQ.

The AK4961 is an Audio DSP Codec which basically allows for recording features such as always-on voice recognition (That weird Voice Unlock thing in stock) and noise cancel.

A quote from their website:

"The AK4490EN inherits high quality sound technologies of the AK4490EQ that has been adopted by many audio products since it was launched in 2014. Axon7 is the first smartphone to launch in the market using this ultimate sound solution.In addition, the AK4961 enables a natural sound recording by utilizing a derivative of AKM's advanced ADC technology used in today's recording studios enabling a professional level PCM recorder. This key feature is utilized during Video recording, Karaoke and other multimedia applications. This recording performance is also improved by an advanced noise cancelling algorithm running on the AK4961."

And this is an Android Authority review of the older ZTE Axon:

"The Axon phone boasts a “Premium 32-bit” AK4490 DAC which supports sample rates up to 192 kHz, features five digital filters, and AKM’s “Velvet Sound” technology. This is coupled with an AK 4961 codec used for recording functionality, which offers four differential channel 24-bit ADCs that operate up to 96 kHz."
[ZTE Axon 7 Questions & Answers] Dodgexander:
I'm confused, what is this UHQA patch and how do we know what hz sound is routed?

Even if we have a display showing 192kHz we still don't know if any resampling is going on.

Also for the sake of testing surely this should be done on stock first to eliminate any possibilities the custom patch could be throwing in?

It's annoying the specifications of our dac support these formats yet it's held back by proprietary blobs. Argh

[ZTE Axon 7 Questions & Answers] pinkywinky:
Yes I agree with you. But the 4961 is the adc, but it is also the non-hifi dac. It has 2 responsibilities. But our phone never uses the snapdragon, which is what I was trying to get at
[ZTE Axon 7 Questions & Answers] LazerL0rd:
Yeah, sorry about that. I took a break from SAURON's dev team and only recently caught up to action. I can tell you in the next release we'll be including a few more goodies for the Axon 7 that should help.

The effect also depends on which ROM you are originally coming from, as I have noticed some PA/AOSPA ROMs do not take much effect from SAURON.
[ZTE Axon 7 Questions & Answers] Choose an username...:
Hey, do you know if there's any way to confirm this? We have no idea whether the DACs we can select are the AK4490EN and the SD820 DAC or the AK4490EN and another DAC on the AK4961, as the other guy says. Would there be any reference on the files, or whatever?

It sounds weird to me that the codec chip would have another DAC inside, even if it is low power.
[ZTE Axon 7 Questions & Answers] LazerL0rd:
I guess the "encrypted files" he mentioned ROM devs are using might reference them.

Mixer paths XML is also a good place to look for audio routes.

I think tinymix could help with that, although some phones don't have support for it. You'd have to ask one of the other AINUR devs ( [MENTION=6366997]UltraM8[/MENTION] or [MENTION=6037748]Zackptg5[/MENTION] ) or even better - the guy who helped with the Axon 7 support (not sure who he is).

PS - I'm currently without a phone so it's pretty difficult to debug stuff, sorry mate.

So far I love it. One of the first things I did was download Google Now launcher, as I was coming from a Nexus 6 and had the Nexus 5 before that, and the Nexus 4 before that. So yeah, I was really used to stock(ish) Android. I can deal with most of the software changes I'm dealt with, it's no big deal to change the way I used to do things. Sometimes I think purist Android users can be over the top, but that's like anything else in life.

It's fast as hell once I turned off animations like I always do. WIFI reception seems average, and so does the network. I love the thinness of it. (remember I came from a Nexus 6 which is wide as %$#@) It feels like it was made for my hand.

I'm obviously not going in order here, but even the unboxing experience was very nice. Very neatly packaged in a slick white box that screamed quality. And they included all of the necessary accessories to have a nice first impression. They included a USB-C to Micro USB converter for those that need it, a plastic screen protector, a clear case, a quick charge wall unit, and an over-the-top sim ejection tool that can be attached to your keychain. Nice. Sometimes it's the little things that really matter, and you can tell a company actually cares about its customers. Anker is one of the best when it comes to customer relations. Keep that in mind when buying cables or chargers.

After watching some of the Youtube reviews of this phone, (after I bought it) I was a little worried if I had made a mistake. After getting it and using it for a while, all of those concerns are negated. It's just fine, and a hell of a deal (I got it for $329 from Newegg). Even me being a long time Rommer and rooter, I don't feel the need to Rom. (that may change) Google Launcher works great, so I'm happy.

There's a bunch of tweaks I have to do yet, but so far it's been nice. I have no issues whatsoever. It's just a good solid phone for what you pay. $329 is actually a good price at this point. And even cheaper if you don't mind gently used. Thumbs up on this phone.

I had much the same experience with mine, loving it at first, and also coming from a Nexus 6. I'm planning on selling mine now though as I've been unable to unlock the bootloader to get root and custom recovery. The stock software isn't bad compared to some, but compared to the freedom you have with the Nexus 6, being stuck on stock unrooted kinda sucks.

It's been kind of a pain trying to sell it again not at a significant loss though, so I'm thinking about trying to give it another go and unlock the bootloader. I was running into the problem of not being able to mount the SD Card in recovery to flash the B20 firmare.

It really is a great phone hardware wise. I absolutely love the bright, vibrant screen and the speakers are great. Plus I like the look of the phone overall. If I could just get the software I wanted on it I could live happily ever after, lol.

Sorry for totally off-topic, but I have no idea what you mean with flashing the B20 firmware. If it's the same process as the A2017G just using axon7tool (axon7toolkit might do it too, and probably easier) works. After you have TWRP you can spam the SD card option under Mount and it'll mount itself eventually. Or use the USB cable via MTP on TWRP. but again, what B20 firmware?

I don't know if I'll be able to help you, I just read most guides for the A2017G. Try axon7toolkit since it supposedly works for all 3 versions and can unlock your BL.

And the review, I honestly don't know what kind of mind control ZTE uses on the stock ROM, but I'm constantly going back to it after trying other ROMs. It works nicely if you don't count the things they break on every update, but hey, it gives a little of thrill to the whole situation (Will they fix Google Play?

[Android Q&A, Help & Troubleshooting] cognitivedissonance:
Hello, I'm traveling out of the country soon and it's going to be a major change for me because I'll be going from an unlimited data plan to a very restricted amount of data. I have a lot of background processes, push notifications, syncing, etc going, which normally consumes a lot amount of data.

When I'm out of country, I want to essentially stop all data and syncing save for whatever VoIP and messaging solutions I choose.

So for example, I want to limit Gmail, Facebook, Instagram, Snapchat, Google app, and other the other stuff that's constantly using data, pushing notifications, etc, but still have messages/calls come through on Hangouts, Google Voice, Skype, Facebook messenger, or whatever I decide to use. Ideally I'd like to download Google or Waze maps on GPS (I believe they both cover Italy) and then turn off data and only use the GPS radio. Still, if I need to turn data back on for Google Maps, or to check my email, I don't necessarily want data and syncing turning back on for all other apps, and I don't want the app to continue using data when I'm done with it.

I also want to ability to remove the limits on all the apps as soon as I'm in WiFi. However, WiFi can be unreliable, so I don't want to enable data for everything and accidentally have the WiFi drop and the 3G/4G turn on. I assume this means turning off the radios, however, I don't want to lose the ability to text/call (emergencies only) so I'd want to leave that particular radio on.

Is there an app or Android feature that would let me play with data usage in this manner? I'm rooted running stock 6.0.1 on my Nexus 6P.

Thanks!

PS. Unless Tasker is a lot more fool proof and easy to learn/setup than it used to be, I just can't use that as my solution right now due to lack of time before I leave.
