V4A is an awesome mod for clarity and loud sound.
Atm I've just installed the updated version. We could share our respective settings mentioning if it's more for quality (XHiFI) or effects (FX).
Actually I use the recommended settings with Sony IRS and it works really really nice!
One of the best thing to have on our Android device!

Erisin ES2046B (4.4.4) installed and set up. Question regarding sound amplification

Hi all,
I've just installed and got everything up and running on this unit in my E46 and had a question regarding the audio quality when playing music.
I use GoneMad music player as it's got one feature I haven't found in another music app, standard star ratings support embedded in the music tags (all my music is rated), and as such have set up smart playlists that only play songs rated 4 stars, 5 stars etc. This way I can carry and sync my entire local library between phone, car and PC.
Now, I've toyed with the GoneMad EQ settings and can't seem to get the sound to be as crisp as I used to have on the Parrot Asteroid Smart I used to have before.
I installed PowerAmp just to see how much of a difference that makes to the sound quality, and indeed after tweaking the PowerAmp EQ settings, the bass is much richer and treble is clearer.
I have already set the Android headunit's "Amplifier" preset to bass and treble boost by the way.
I have enabled root on the unit, and essentially all I want is to be able to use GoneMad, but with the audio quality of PowerAmp. In the past on my Android phone's I'd installed Viper4Android sound and that's improved the phone sound output to headphones, but Viper4 doesn't seem to install the audio driver on this headunit once the app is loaded.
Can anyone advise on what I can do to improve the sound quality of the headunit without resorting to soldering the IC bypass? I know the sound can be improved via software, since PowerAmp does something the other are not doing, so can this whatever that is, be done via a root app?
Thanks!

No matter, fixed it, installed Viper4Android FX, updated Busybox and tweaked the Viper EQ and clarity modes to suit. Night and day difference. thie cheap Chinese head unit is now excellent everywhere.

what is Busybox? also, thanks for updating your thread with your answer. I'll be getting my Android head unit in a week or so, and I may need this fix too.

It's what various root apps like this use to run their features.

If you can afford it, worth spending a little more and going for the ES4046 model. It uses newer hardware (MTCD instead of MTCB in the above), runs on Android 5.1 and supports DAB+ (if you spend an additional 50 dollars on the DAB module). I have the above which is good for modding but development focus is moving to the later model so probably a little more future proof.

I've got another Erisin (ES3015V) and I'm pretty unhappy with the sound quality as well. Installed Viper4Android, which makes it better, but I'm still not happy. It can't compete with my original low end stereo (RCD310/Skoda Swing). Could you share what you did with the clarity modes specifically? Thanks!

Not the same high quality.
Maybe 40-50% of Note 9/S9 quality.
And you will need extra custom kernel installed like elementalX etc to give boost to volume.
By default only the stereo mod is not enough to take advantage full stereo and audio result.

It is a common misconception that stereo speaker mods break your earpiece, but most of the times you'll be fine till there are no distortions in the sound from earpiece.
I've reduced the gain in the initial version, will increase it once there are more testers.

Yep. Luckily the root software, Magisk is what you'll need to root, and install this module!

"It is a common misconception that stereo speaker mods break your earpiece, but most of the times you'll be fine till there are no distortions in the sound from earpiece."
Hmmm I'm still skeptical

Thought I try this for the OP6, as the latest update (9.0.2) for OP6 meant that the stereo speaker module stopped working.
This module, for OP6t, did not work on the OP6 in fact it messed up the pattern lock which meant I could not get into the phone.

You're right acervenky, it is working. Not sure why I was having issues, it's possible that the module from Chrisaw was causing the issue.

Well, I have not seen someone with a busted earpiece since 2013/14. I've always use these mods and my devices have been fine.

Will both speaker have the same volume and adjust accordingly if one tunes the volume up and down?

The top speaker will have lower volume, the volume of both speakers can be adjusted according to your preference by using the Cleanslate kernel & its application.

Works amazingly well with ViperAudioFX.

I am not able to install this mod on my 6T via magisk. Whenever I try to install it, the zip file is greyed out. (IIRC it's just a '+' in modules, right?)

I use the custom setting, and adjust the bands below the line. However you cannot use the Bass or Virtualizer with the speaker. The speaker is too small and weak for those adjustments IMO.

I'm missing Atmos as well. You may want to look at Viper4Android if you're rooted.

Yeah absolutely! Just installed viper and work the way should work...i assume that dolby not support pie at moment but i guess viper work for me now...

I'm still on 9.0... Tmo... I notice that it works on some streaming apps but not all. Works with Gmusic for sure. It does work on speaker as well. Not nearly the best EQ but it's usable.

I just got the T-Mobile 6t and I came from an LG G6 . And I noticed a big difference in sound quality in Bluetooth.
I had to recalibrate my car stereo eq settings in my car.
To me it's a downgrade in audio quality. Less bass and just doesn't have the umph. anymore.

Same here...came from v20 Bluetooth audio huge difference... volume is not that loud via BT i has dolby Atmos on v20 and sound amazing compared to OP...i used Viper to increase volume but seem it dont do anything...looking for a way to increase volume...

I didn't install yet but to involve in the discussion, for me compared to my nexus 6p it's a noticeable difference with the Bluetooth, it's better then I had before. Also via Android auto it's better quality then I had before.

I came from my trusty dialy driver the OG Moto X Pure -Rooted - with Sauron Audio Mod and Dolby Atoms EQ. The sound is phenomenal through BT even with the outdated codec. I hope to get the 6T to that level and even better. Patiently waiting to root my TMO Variant. On a side note; the sound from the 6T is pretty good through my gen1 QC35s.

Installed non root tmo.
It MAY be doing something but I can't really tell with the speaker...using headphones I can tell more(bass effect works etc)
I need to pay this phone off before I can root it LOL, that's a new one........just got it with EIP.
Viper is only reason I see the need to root tho. This phone is fantastic. Coming from s8.

I don't notice a difference, using Spotify or YouTube

After you install it.. Go and switch off the battery optimize for the app so it won't stop when playing music

AndroidAuto low volume

Does anyone face issues with low volume or lack of audio quality when using android auto?
I mean sound is ok, but its not as loud as other devices i used with AA.
I have tried the internal equalizer and dolby atmos, it helps a little but still not the same.
I have also tried the app EqualizerFX and so far seems better but not 100%.
Do you use any other method or app for this.
I am on the brink of rooting and going for Viper, but thats my last resort

i use poweramp pro ... it boost volume and bass for my buds - works a treat and it downloads the album art and instantly adds it to the track - quite nice

Have you upted the Bluetooth setting to loud.
In the media playback mode goto setting / sound setup/volume setup/Bluetooth audio.
Makes a huge difference on mine when using amazon music etc......

I ended up rooting and using V4A, sound is full and sounding nice now. (although now with root i have google pay issues - but i guess i use audio more often than gpay)
On stock no matter what i tried the sound was just dull.

1. Bluetooth on the phone has its own volume setting, I hope you pressed that volume up button on the phone, then said "OK" to earpiercing warning, and then pressed volume button up again until you reached max
2. Dullness of sound cannot be cured with any settings on the phone - in Bluetooth original data just streamed to the car (being compressed/decompressed along the way)
3. You can still play with audio setting to affect headphone jack quality - it helped me.

yes i know that.and yes that was basically the first thing i did.
and btw this issue with Android auto is not to do with bluetooth or jack.. it uses usb dac to stream auto and control to the AA interface.
anyways, as said Viper4Android sorted my issue, as it processes audio differently to the stock audio processing.
same as poweramp, has its own audio processing, also for usb dac
