Digital to Analog Converter (DAC) - a device for converting a digital (usually binary) code into an analog signal (current, voltage or charge). Digital to analog converters are the interface between the discrete digital world and analog signals.

Activation methods
Since a very large number of questions, disputes and flooding have already accumulated, I will argue based on an opinion and explanations that are authoritative for me.
In general, I would not do anything to improve the sound except This instructions plus specific settings Neutron Music Player (Post adbo # 8042908)
but nonetheless, we always strive for excellence.
Let's go!
A MANDATORY condition is to make a BACKUP system before manipulation, it is safer and easier to experiment with. Use only ONE of the presented experiments at a time, that is - they made a backup - activated the dac - not to their liking - we return the backup - we try another way, only this way, it will save the system in frequency and save the mess in the sound.
Final patch for activation from a local music lover and74
Addition to the instructions for the activation of the DAC
Who has not yet activated a DAC, you can try to activate it with either a patch
Another way to activate a DAC - carefully, the kit comes with a Noozy player and ViperFX- the basis of fashionAmplio
A small educational program on running sh scripts in android - why the hell should I know about running scripts, you ask! And I will answer - suddenly you are an ardent opponent of the root, and your ears wanted to indulge in an amazing melody, in this case, read this article
Well, suddenly, someone else has not installedRadio
The solution to all issues
"The fact is that the manufacturer will not inject the DACs into the device and do not activate it at the same time. This is at least stupid. The core for the DACs needs a driver that tells the system its bus. Because in 5.0 they removed the layer-internal system frequency limit , and ES9018 is absolutely omnivorous, it is concluded that even on the most halim firmware your DAC is turned on and working fine. Even on the Galim runoff everything works fine and there are no restrictions and everything that you have imposed on yourself.
The only thing that leaves much to be desired is the poorly implemented soft audio path, which implies both the DSP component and some flinger elements. Amplio in this regard is a little more than enough. Why fence gardens and reinvent the wheel? I don’t understand.
What does ALSAMixer do? it allows the standard media library to pass the entire stream through the chip, and this, in turn, creates cross-distortion and little thermal noise from the excess work of the piece of iron.
ALSAMixer is obtaining access control for alsa drivers from under the system, conveniently displayed through the switch and having a toolkit that can control gain on buses, including DAC and CPU codec bus. It’s not capable of changing sound if you don’t touch it. "

Settings - a joy for the ears
We turn off the lyrics, ratings, 64-bit processing and volume equalization in the main menu. In the discretization menu, select “audiophile.” In the audio equipment menu, reduce the hardware delay to 80, turn off the basic driver, audio focus and dithering and enable “access to usb DAC”, “follow for the frequency of the source. "

Friends! A patch on the skeleton of the mod В® Amplio version 2.0 has been releasedPPTV King 7 - Discussion (Post by and74 # 57762926). Who is looking for a sound with perfect :) detailing is what you are looking for! We put, try, write reviews.

I looked at the presentation of the body - it seems that hi-fi audio is implemented only in the S version ... sadness: unsure:
PPTV King 7 - Discussionhere you need to fix small errors.
Instead of 88000, you need 88200. And after 88200, 96000 goes right away, and here it is 32000 by mistake. Well, it’s okay. The multi-sample was launched with such lines, the main thing was that its frequencies were 44.1.48.96 and 192 kHz.

I looked at the presentation of the body - it seems that hi-fi audio is implemented only in the S version ... sadness
and here you are mistaken))) here is a quote from a review from the reputable ixbt site:
“There was a great deal of embarrassment at the fact that there wasn’t a word about the sound at the model’s presentation and it’s quite clear why: the fact is that by default the sound of PPTV King 7, although good, does not give out everything that it is actually capable of. To unleash its potential, a whole procedure was invented for which Root rights are needed. The first part consists in replacing the audio_policy.conf file with frequencies higher than 44100, which in my opinion is completely redundant. Then, we recommend installing the AlsaMixer application, in which you need to change the Set_HIFI_es9018_State parameter to Open "I don’t know if changing this parameter strongly affects, but with the new driver from Alsa the sound becomes noticeably better."
and here is another quote from the same review:
"The sound quality is really just excellent. I can compare it with the Meizu MX4 Pro and Gigaset Me smartphones. The sound quality of the PPTV King 7 is closer to the Meizu MX4 Pro, they have approximately the same detail, but Meizu gives a more“ murky sound, "at that time how King 7 gravitates towards transparency. The sound implementation of Gigaset Me is noticeably better than both of these models, Gigaset has even higher detail, slightly tinted high frequencies and there is not some “analytic sound” that is felt in King 7. PPTV. By sound capabilities, I would put PPTV King 7 one step with Meizu MX4 Pro "

no instrumentation or tampering
Well, in this review, and some measurements are present)))

some measurements
Hokadi here is another reputable site giving full technical specifications

can an autopsy reveal the truth to us? )))

I won’t talk about the non-name of the Chinese, there Zopo was different, and some versions of TCL ...
I am happy to agree that I am wrong ... but evidence is needed ..

Hokadi but they have a difference of 30 bucks in the pink version))), so you can play it safe and take S

But there’s nothing “respected” in this site or in the like,
Xokadi , Well, the fact that the people laid out the photo at the beginning of the topic, disassembled by king, the ess chip was clearly visible there.
As you can’t see, I saw the photo with my own eyes.

disassembled king, there was clearly visible chip ess

You need to search, but one hundred percent ess chip is visible.
and where to look for something? in the header there is no photo of the disassembled smart, it is only with the cover removed, but they don’t even take out the battery there))), will you have to find it yourself in your purchased phone, and if it is not there? then what to do? to China send back?
that's why I try to buy such non-names)))
