So, thanks to the researches forumchanin
rostislove91 it became possible to activate the DAC ESS ES9018K2M.
After simple manipulations, the DAC works everywhere (at least in all the players that I tested).
This requires only the root and your desire to squeeze out the maximum sound the phone tract.
All tested on a regular firmware 2.0.
1. Get the root (in the cap all there).
2. Download
В® AlsaMixer (Post by Neuropapa # 46920340)3. Download the file of the Management Board audio_policy.conf
https: //drive.google.c...mWlU/view usp = drivesdk?4. Copy Alsamixer audio_policy.conf and a telephone number (yet at any place, such as the Download folder)
5. Open Root Explorer go to the etc folder (located in the root), we find there audio_policy.conf file and copy it to any place (for example, in the root of the SD card).
6. Go to the folder etc through Root Explorer and do the right R / W
7. After Root Explorer copy file downloaded earlier (in step 3) audio_policy.conf etc in the folder (replacing the original file).
8. Expose right audio_policy.conf file as shown below T (long tap on the file, referred to as "authorization").
9. It is very important! Put back mode r / o on the folder etc.
10. Reboot.
11. Set Alsamixer.
12.Otkryvaem Alsamixer and looking for value Set_HIFI_es9018_State
13. Tapan Set_HIFI_es9018_State and see that by default is Close. Write the word Open, then apply.
14. Reboot.
15. Check whether all we've got. Insert the headphones opening any player, turn on the music (it is important) and go back to Set_HIFI_es9018_State. If you do so, as in the screenshot, so everything turned out. That is, when headphones are connected and playing music, the DAC is switched independently. Unplug your headphones or stop the music, it is deactivated.
Basically all you need nothing more. Sound more natural, assembled, with good separation of sound, good bass control, excellent detail, no porridge on complex compositions. The sound is no longer tired after a long audition.
In this tract rather dark sound, so fans of bright sound might be slightly disappointed. The slope in the dark side, I think due to the fact that the manufacturer did not bother to make at least some harness this path. Hence we have a bias in the dark sound and a very modest stage. But it's all garbage, the main thing, the main thing that kind of money we have and a great phone and a normal DAC.
A small addition. Due to the fact that after all the manipulations activated by the DAC, player Poweramp alpha build 703 now sees an opportunity to play HiRes audio on this phone (earlier this was not).
Therefore, all who want to fully incorporate it into this unit, the following will give short instructions on how to do it.
1. Download
Poweramp (Post clever_man # 48897310)2. Go to the sound settings and look for the "Audio".
3. Next, go to the Hi-Res yield.
4. Turn the switch to 1 and hit 2 GEAR.
5. The sampling rate set to your liking. audio buffer size set to "very high" (for some reason, the base value is rare crackles in the sound). We put the check where the number 3 (cuts off all jewelry poweramp and we only get a sound DAC + AMP player without additional processing).
Well, actually everything. use :)
I express my deep gratitude to our humble forumchanin
rostislove91 for the idea and its realization.
All sound good!
