Random Actions in Default Music App? - ZTE Axon 7 Questions & Answers

I haven't been using the default music app because randomly it does an action after a while of playback, pretty much every few minutes; back, forward, pause, whatever, it random action just randomly happens. I've wondered if I somehow accidentally used some sort of gesture or touched the screen, but it happens when the screen is off as well and there doesn't seem to be any gesture that would affect the music app anyway. Does anyone have any idea what can be causing this?
I've been using PowerAmp which doesn't seem to support the A7's DAC. I have it set to 24 bit sound in the last Alpha of PowerAmp (which was many months ago, I've given up on any update for PowerAmp ever arriving) but after side by side sample comparisons they do sound different. The problem is I'm not sure if there's a slight volume difference between programs causing that, or if it's some setting, or if it really is due to the output being done on different DACs resulting in the differences. Pocket Now's video stating it only outputs 16 bit downsampled audio has also stuck in my mind, but despite contacting them twice on different social media, they never responded. That's infuriating, making a bold statement like that, then never providing an explanation and leaving it ambiguous, never stating if the downsampling was at software level, firmware level, or anything.
So I basically have no idea what the hell is going on with the audio on this thing in any way, from software to hardware. That's incredibly frustrating considering the DAC is a major reason why I bought this phone instead of something else.
Edit: I forgot to ask, what software should I use to confirm what sort of bit rate depth the Axon 7 is outputting? I have a Sound Blaster ZxR for recording, so I can plug the A7 right into that.

I can't tell you how to test the depth of the audio coming from the cell. If you can't tell the difference is there any real point? It it just a matter of wanting the product you thought you were paying for?
For the other issue, a really simple thing you've probably done already is checking that ZTE's voice software isn't enabled for media control. An old S4 of mine would go "back" any time a sound remotely like a short "a" played.

I can tell a difference, on the default music player it sounds better, for example instruments sound more crisp and separated from the rest of the audio. The issue is that I can't tell if that perception of more crisp/separated sound is due to a slight difference of volume between programs which is difficult to perceive. Just to add to the confusion, different songs seem to have different volume levels on each player, which aren't consistent. For example song A may be louder on PowerAmp, but song B is louder on the stock player. In those cases where the songs are clearly different volumes (maybe 10% of the time) it makes it extremely difficult to tell which one sounds better to me. This is with all equalizer/Dolby settings disabled.
Humans easily mistake higher volume for "better" quality in various ways. That's really the reason for the "volume wars" or whatever it's called; music was often mastered with levels just blasting instead of balancing the audio properly.
What I was asking is what free program can I use to record audio from my phone to check if it's outputting 24 bit audio? But on that same note, yes, I suppose that would also let me directly measure volume as well.
As for the voice recognition, I'll try disabling that and see if it helps, but isn't that supposed to only work when holding down the back key anyway? Also, often when it did a random command like next or previous song, I was silent.

Ah, I see. Sorry to not be helpful whatsoever.

Hmm y somehow ZTE has volume differences. I also noticed it if i enable/disable Dolby Atmos.
But i also think that ZTE set up some DSP stuff on AK4490/61. I would be happy if there was an app which could change DSP etc settings of this DACs :/

I also noticed the fluctuating volume, for me it's via bluetooth.
It would progressively become quiet and when the next song starts it would scare the crap out of me (much louder), then repeat.
Rarely, it would continue to play randomly after I disconnect from bluetooth (not immediately after).
So it would be nice if someone found a good music player that takes advantage of the DACs and not exhibit random behavior -- alternatively if this was fixed that would also be good.
EDIT: For me, it happens in a certain volume range in the upper end. Anything lower or higher this does not happen.

Audio issues (stuttering and granulation, artefacts)

I'd just like to see if anyone else is getting any audio issues, as I've noticed a few small things that marr the otherwise excellent audio quality that I get while listening to music:
- On bootup, the startup.wav sound often stutters, or is finely granulated.
- While navigating through menus, sometimes the audio stutters/is granulated. If I'm right, it correlates to the cpu clock speed being ramped up due to coming out of "sleep" mode. This is just speculation of course.
- Whenever audio is played, there is a very quiet but audible (with a reasonable set of headphones) click, followed by a quieter "hiss" which then plays throughout the audio being played, and for a short while after.
Now this last "symptom" I've heard on many audio devices, some much worse than others, with a rare few having no noticeable noise whatsoever. The Dell Streak I owned for a short time had a relatively loud and distinctive "click & hiss" combo - it was one of the reasons I changed to a Galaxy S. It just surprises me that a device where many people are praising it's audio playback qualities (for me) has some issues.
Anyways, I'd like to hear some thoughts on this, and maybe some people who have no issues whatsoever, with quality headphones, could show me that my particular device needs replacing - or that it is common to all devices.
I get the stuttering on start up everytime, I was also listening to some audio last night with headphones and there was lag and stuttering, I didnt hear any hiss but it was not a smooth process expecially switching between apps with music player running, it froze up for a few minutes.
I also tried going through the music player menus and not everytime but sometimes it would stutter just going into settings, at times this phone frustrates me more than my G1, but with the G1 i expected that, especially running eclair roms.
RUNNING JG5
I'm partly hoping that maybe FroYo, with it's cpu usage benefits, might help with the stuttering.
I'll also try to do a decent recording of what I mean later on tonight - Im at work with a laptop at the moment, so the recording quality is dire. I have no idea what I'm doing in terms of impedances/loads either - it means nothing to me
e: I've had a look in the other threads regarding audio - the one about the default EQ is interesting it must be said, but there are no direct implications for the issues I'm hearing here.
I should post my software version as well, though the problem has been endemic to the phone rather than the currently flashed rom - I currently use JM2, overlaid with SamSet pretties, Mimo's kernel and LauncherPro.
2 phones here with a hiss/whistle artifacts during the talk :-/
I recorded a vdieo the other day & the audio was totally trashed - all I got was gargling crackle. It was bad enough that I thought I'd got water in the speaker aperture! But playing music is fine (to my ears, anyway).

[working] sound issues and hardware/software link

Hello there everyone.
I am working on few of problems faced by Nexus regarding its sound quality and other issues related to hardware and software. One of the device has confused me completely is been addressed at the end of this thread.
Mostly, according to my experience, the sound is very loud compared to its previous model of Nexus 7 2012 which had mono speakers while this is loaded with two stereo speakers. Using it in portrait mode has best sound experience.
However, if you try the surround sound option via Google Music, the sound isnot really loud. Just without it, I have noticed best performance.
Also, in MX Player Pro, I have seen that with good headphones, you can increase the sound upto 30 (rather than normal 15) yet you can not do the same whilst using the speakers. It could be due to codecs.
Overall, the sound is loud in a quite environment but hardly noticed in busy areas with background noises like streets. shops etc even on its full sound.
However, some devices do have a bit low sound which could be increased by modifying files a bit but this is kind of increasing your speakers output more than it is optimised to be used for. Thus, sound may break and might be distorted. I am trying to find a combination where an optimum balance could be achieved but I haven't been successful. (If anyone has these values, please share)
I havenot come across a speaker problem related to hardware where no sound was coming out of it. Although, few devices do have different maximum sound if measured in db (3 to 5 db on same track)
THE DEVICE
The device came without its top speaker working and after opening it up and checking the speakers, both speakers worked. I thought the reason, it was not working was due to software. I tried looking into it deeply through software modification without any luck.
One day, after heavy gaming out of curiosity, I just turned on songs to check if both speakers were working and viola, both were working out of no where without any software modification (I gave up and reset the Nexus to give it for warranty claim the next day).
I was overjoyed and till next day, both speakers were working perfectly until I did some heavy gaming again and the sound vanished after charging it (It got hot again during charging)
This has happened twice and today I was gaming with sound turned on and nothing. The device top speaker didnot turn on for a second even like two times it happened before. Both that time, my device was silent while gaming.
I suspect some wiring issue but still not sure, I am now a bit sceptical to open this Nexus again and void the warranty as I have already have taken the back lid off few times. I do not intend to heat it with soldering Kit as I have damaged Htc Sensation a while back doing that. Any Suggestions about this device in particular?
How have been your experience with sound quality and do share any mods you have find useful and have tested.

[Q] Audio Jack Issues?

Just came across a disturbing report in a very recent Droid Life review of the Note 3 (from a list of N3 reviews posted on this forum) concerning "Audio Jack Issues". Anybody who treasures their hearing and uses their phablet for audio material (including movies, music, audiobooks, etc), especially using earbuds or headphones, might want to "listen up." The following is an excerpt from the review:
"...When listening to music through the 3.5mm jack, you are sometimes met with a very weak sound. It’s as if the sound of the music isn’t “full” or quite loud enough. Then, after a few minutes without touching anything while at full volume, the volume just explodes and you are left deafened by the surprise volume attack. Some people are pointing towards low-impedance headphones being the issue, but I have had the problem on multiple pairs of headphones, in-ear buds, through car decks, and everything else. It’s a very frustrating and reoccurring issue that I wish Samsung would find a cure for. Until then, I fear listening to music out of this device because I don’t want to go deaf. It might sound crazy, but it’s a very real issue that I experienced over the course of time I had the device."
I've had 3 Samsungs: a flip-phone a few years ago, a Fascinate 2 years ago, and currently Galaxy S3, and just preordered a Note 3. Of the three previous phones, two had infrequent but definitely-occurring audio issues where the volume changed unexpectedly. The flip phone blew out my ears once, and swore after that would never buy another Sammy (what a kidding-myself that turned out to be). What's unnerving is this seems to have appeared intermittently in multiple samsung phone models (the article reports yet another audio jack issue in the S4).
Chatted online with a VZW customer service rep. about this, who was really no help (wasn't her fault, i guess). She just regurgitated the company standard lines--14 days to return, restocking fee, can get a replacement if the problem occurs, etc. But she pretty much stated if there turns out to be a Note 3-specific issue, the customer is stuck with that model of phone; don't expect help from the carrier other than replacing with an identical unit might likely have the same problem; if you enjoy any kind of audio produced by the phone's audio jack, use it at your own risk. (Even more dicey is that it's intermittent--no guarantee you'll be able to demonstrate it to the carrier's service rep.)
Furthermore, i was one of those who got a free continuation of unlimited plan (thanks to the VZW ordering "system glitch" last weekend), which has been reported in the last day that VZW is going to honor contracts which show unlimited data. This rep completely contradicted that and claimed my data will be capped at 2gb at activation time. So with this diametrically-opposed chatter from VZW, what is one supposed to believe? Really suggests getting a satisfactory resolution from any carrier on a brand-specific phone problem like this to be wishful thinking.
Any thoughts or has anybody experienced thru-the-audio-jack sound issues with sammy phone products? My take is i'm not going to be on the bleeding edge of this one, too much of a hearing risk, cancelling preorder and wait for more reports on the N3 as time goes by.
For sure something is wrong with mine. (tmobile N3) The output levels are maybe half or less what my N2 can put out. I have carefully setup audio systems in my house and car, and it is unusable. Its also not USB compatible with the new Kenwood KMM 100u deck that plays FLAC files. It must be a glitch they can fix, i hope! The jack SQ sucks right now.
I hope mine won't have this problem.

I got that the first time you said it.
im experiencing this too with an AU Telstra Note 3.
ive tested it a bit and it seems like its 2 separate things to me, but I could be wrong.
firstly it seems like all EQs either crash or just lose their settings at random moments. this can be things like between track changes or when the 3G signal drops out. if you go back into the EQ panel it will kick in again, almost like it was off and you've launched it again.. very annoying. ive verified this with both the stock EQ and noozxoide. the difference in volume is minimal though, its more quality / bass / whatever EQ you use.
the second part with the volume dropping out completely only happens to me between track changes. if i pause the music for a couple of seconds then play it again, it will play at normal volume. fast forwarding between tracks is the most obvious since every other track will be minimal volume, and the ones in-between normal volume.
ive only tested this with google music. although my phone isnt stock now, the same behaviour was there out of the box. using etymotic earbuds with reasonably high impedance but i doubt thats the issue since pause/replay fixes it.
Doesn't happen to me on N7player or PlayerPro. (nor on videos in Dice, MX or VLC.)
Try not using stock apps if you have the issue. Might just be a stock problem.
I can't test Google music, I disabled that. Stock player itself is too annoying for me to try.

Got the same here. N9005 with Google Play Music. Sometimes it's also (it seems) input-triggered. Sometimes when I push Menu or Back button, volume goes down and when I open Browser volume goes up. I know this sounds like voodoo and I'm completely crazy but I got this situation some times now.
With original sound files this problem came very often but after installing sound mod, it became seldom but not solved.
Annoying!

I actually moved to the stock sammy app since it was irritating me so much. i have to say though, that if you can be bothered syncing a playlist to your phone that the sound is much better through that... hard to pick fault with.
i set up galaxy adaptive sound first, which is the one that plays high med low tones through left and right channels on your headphones independently and lets you tune it. found a much more balanced tone coming out after that, to which I then applied higher bass EQ settings from within the sammy music player and it sounds pretty good. some distortion on really heavy bass tracks at high volume, but very nice otherwise. MUCH BETTER than variable bass and audio volume on the google music player.
i think samsung neglected to test the standard music APIs and borked them, but their own proprietary ones work fine. the adaptive music filter doesnt work in any player apart from the sammy one I read.
since i cant cross-flash regional roms without voiding knox warranty i havent tried the updated EU roms, but maybe they fix it there?
Experiencing same problem on my AT&T note 3. Google Music tracks will randomly apply a shoddy EQ setting that is either too loud or too soft. Then the next track will be normal. It explodes my ear drums constantly. I have the EQ set off also, but that doesn't seem to matter. Also unplugging and re plugging the headphone jack "fixes" the issue as well. I'm pretty annoyed by this problem.

audio hiss after 4.4.2 update.

<<SOLVED>> The moto G Opamp is not very efficient. It struggles to go down to 2Ohm stable. This means average earbud type headphones rated at 16Ohms. will have hiss and other artifacts. Higher impedance headphones. 40-70Ohms have much better sq. Much above 70Ohms and I suspect the Moto G won't be powerful enough to drive them.... so, that's the sweet spot!
Hey,
Since I updated to kitkta4.4.2 I notice there is a significant background hiss listening with headphones.
As soon as you use an app that activates the audio jack the hiss kicks in, it is constant, not volume dependent. If you turn the volume down to zero, but the app keeps the sound output active the hiss remains.
when the app is closed, the hiss abruptly stops (presumably when the sound API deactivates the inbuilt opamp to save battery)
I'm about 90% sure this wasn't present under 4.3 or was far less noticeable.
I'm not being picky either, this is bad enough that it would make using the phone as a walkman at a low or moderate volume unpleasant. From experience I'd estimate the hiss at approx -20dB.. this is similar to the hiss you would hear from your average desktop PC fan at idle under your desk..
can anyone test this too, on 4.3 and 4.4.2?
Oh, and use earbud headphones or good closed cup ones. Open phones, unless you are somewhere very quiet won't give a good idea of the hiss..
thanks
Can confirm this on 4.4.2, too bad I didn't see your post before updating, as I don't really remember how it was on 4.3 :/
You don't actually have to use earphones, it's noticeable through the speaker, too (well I'm in my room alone and I put my ear close to it). However, I wouldn't say it's very significant - when using earphones I can hear it when muted, on the 1st bar after mute; on the 2nd you can't really say if you hear it or is it your imagination; and on the 3rd bar it's unnoticeable.
I can't notice any hiss in 4.3, even if I use a headphone amp. No clicking sounds either when the opamp turns on.

this is what I was worried about. I didnt notice any hiss before either, and I had it connected to a car stereo so would amplify the issue (if it was there).
maybe something did change in the audio settings/drivers then. I have already tried dissablying all the dsp stuff with no luck, still the hiss and click when the opamp switches on/off.
Maybe it was there before though, and it's bad luck with the phone, rather than the OS version.
I have got UK Retail 4.4.2 and I have tried to replicate this. I have tried YouTube, Spotify Play Music and TuneIn. I do not experience a hiss!

Under 4.3 to save battery I disabled apps I wasn't using, including the Audio Effects app, and google play. When you disable them it forces you to 'uninstall updates' which I didnt realise at the time, but I think may have been specific to the moto g, as you cannot redownload them from playstore, or update them.
Would someone be so kind as to upload the FULL apk of their google play and and Sound Effects, from their stock 4.4.2 build?
Im pretty sure this is down to the software API that activates the opamp. (as it is very distinct), it even happens when you activate audio by using the rocker to increase the ringtone volume!?!?!???
It sounds like listening to a really cheap mp3 player with a low S/N ratio...
** edit I mean 'Play Music' not 'google play'
Hi,
I actually just registered to say this was very much present on my moto g on android 4.3 and is still the same on KitKat. It definitely sounds like a cheap mp3 player. Does anyone know of a fix?
Thanks

Now this is getting weird. I think I'll install the ota to see how mine behaves. The G's audio quality decent enough imo. Probably above Android smartphone average. But what I like the most is that it's 100% silent, regardless of the volume setting, headphones or the amp.
Having said that, I will still get a USB DAC solution for it, which luckily has native support on both stock ROMs.

I don't see how this is on-topic, but of course, you can download the update either on Wi-Fi or mobile data.
I don't know what you mean with "hiss", but since I updated mine (today - uk), i have started to notice some "clicks" in musics, that i didn't have before.
I was using PlayerPro, turned off the equalizer, uninstalled and reinstalled it again, and it was solved.
Google music, had no issues.

by hiss, I mean hiss. It is probably around 18KHz, and is similar tot he sound of RF interference on a stereo (alsmost like the snow screen sound on a tv).
It is not volume dependent so it is defenitely downstream from the DAC, and must be the opamp or downsteram from the opamp in the phone. It is most likely from a poor ground some where in the audio path (assuming the opamp isn't awful, anyone know the chip?). It could be due to the single board set up of the Moto G mainboard design. I'm guessing here, but if the PCB has the audio channel close to any of the ground of power channels, this would explain my hiss. If it is built to tight tollerance, this could also explain why some people have it, others don't.
In laymans terms, I'm saying the audio signal is 'dirty. If anyone has every used a PC with crappy audio on the motherboard, they will know exactly what this problem is like. When no program is using the audio driver, the board puts the audio to 'sleep', when you open a program that uses that audio driver, the audio wakes up and you get some hiss, noise through the audio and pc speakers. This is exactly what I experience with my moto G.
if im honest, it's unlistenable, however I'm a bit of an audiophile so I can appreciate for most people they won't see it as a problem..

I found 4.3 to already be noisy with the hiss when using my earphones, which have a low attenuation and so even low volumes sound loud on them. To get around this problem I bought an attenuator which connects between the phone and the earphones. Then I set the phone audio to maximum, and reduced the volume using the attenuator. Setting the phone audio to loud means the hiss volume is low compared to the volume of the sound coming out of the phone.
This is the attenuator I use:

this is a possibility, but its not ideal... sadly this is looking like a hardware issue not a software one though as if it was software, I'd expect it to be upstream of the opamp. The fact your attenuator solution works, is more evidence this is a downstream issue . (as implification induced noise increases with the square of the volume (assuming a logarithmic volume scale))
I'm on 4.4. I notice a slight hiss when music is coming out of the phones speaker, though its completely undetectable if the phone is at around half volume. No hiss when coming through headphones.

Please can you test something, with some sensitive in ear headphones (or in a quiet room if they are normal headphones.)
>Connect headphones to phone
>Make sure ALL apps are closed.
>turn the phones ring volume to zero
>you should hear silence.(regardless of what headphone volume is)
>On the home screen, Press the Up volume rocker 3 times quite quickly.
>On my phone, the headphones go from silent to Hiss, then I hear the 'Beep'.....'Beep' of the volume increase on top of the hiss. Wait 2 seconds after the second beep and you hear the Hiss abruptly stop, and you are back to silent.
I have this problem with all audio activity on the phone, but the ringtone volume trick is the easiest way to demonstrate it.

Or even easier, just press the volume down or up button once in any direction with headphones plugged in. Regardless of what it was set to and becomes set to, you will hear a faint background hum/hiss be emitted through the headphones for a second. This is fairly normal on any phone and even most audio devices. I don't know what you expect really in a smart phone that costs £129 in the UK. It is a compact environment to build so much electronics into and will never be a hifi device.
I tested with 3 phones on my desk right now and they all have a hiss when you first do something to make audio come through the headphones like quickly play and then pause a track. In fact, one phone (Samsung Galaxy Ace Plus) has not only a hiss, but a screech/high pitched whine as well. All of these "noises" that are detectable, become undetectable when volume of anything is turned up past the first or second bar anyway.

I'm on 4.4. I notice a slight hiss when music is coming out of the phones speaker, though its completely undetectable if the phone is at around half volume. No hiss when coming through headphones.

This is a fair point, and I agree is not surprising given the phones price. I think the reason I have posed this question was to a) determine if it could be software related (4.3 vs 4.4.2) but It doesn't looks so. b) Is it universal, or could be a slight lottery and maybe my phone is worse than others. As some people say they definitely have no issue. (granted it could be subjective)
Also, I would say, although it is present in most devices to some degree, it is noticeably worse on this phone than any other I have had. Multiple sony erricsons, galaxy Ace, Nokias.. And my last phone Galaxy S2 had extremely clean audio production. (i compared directly with moto g).
I do concede I am an audio snob though, so don't like listening to poor quality. I never really expected to use the moto g for music, but would have been a nice to have.

Yeah, it seems to me too that you are a bit more on the audio than most people
By the way, I was wondering up to which levels can you really say that you hear the hiss? As I've said before, for me it's definite hiss when muted and 1st level, weird feeling on the 2nd and I can't hear it from the 3rd.

Depends on the music. pop music which has a lot of mids and highs, the hiss isnt noticible from notch 4 up maybe.
Quiet music, classical, R&B & hihop with a lot of bass beats but not many highs, you can hear the background his up to maybe 2 notches off max. But its acceptable from maybe half volume.
tbh it's more of a shame than an issue. I didn't expect this to replace a decent mp3 player, would just have been convenient is all.

Some kind of weird auto volume levelling while using bluetooth audio

Hi guys,
I am using bluetooth audio in my car and I noticed just after buying this phone, that when I set phone volume to 100% (in general, any volume above 67%), which I always do, since stock audio is not much powerful, volume changes rapidly during a song. To be more specific - I listen to electronic music and during every kick, volume goes down and up in the gaps between them, so it sounds like a wave. Higher frequencies or silent passages are loud as hell, lower bassy sounds are silent and this changes 2-3 times a second. It rips my ears off.
With my previous phones used in this car (LG G3, Zenfone Max 3), I never had this issue. I even tested some very cheap phones, every single one of them was ok, sound was not even distorted on max phone volume. On any bluetooth headphones it's the same case, so it's not car audio issue. Also when using corded headphones or aux, sound is perfectly fine as it should be.
What I already tried to fix it:
Messing with every setting in developer mode
Unpairing smart watch (just in case)
Tried loads of different audio players - with no EQ on, just flat
Reset to factory settings
Nothing helped. I lost almost a month with Asus "so called" support, I even shot a video for them with clear evidence what is happening. No help, except they tried to make an idiot of me. I get angry just thinking about that communication with them. Am I really the only one with this issue? I don't believe that warranty claim would solve anything and I really want to keep this phone.
Any help would be really appreciated. Thank you.
Try this, Goto Developer Options, activate the "Disable Absolute Volume" toggle (see screenshot). Disconnect and reconnect your Bluetooth connection. Hope it'll work out for you.

Actually, this was the very first thing I tried. Just to be sure, I did it once again together with disconnecting and reconnecting as well, nothing changed...
How about set whatever player you are using to be not battery optimized? I haven't been able to try any fix since I seldomly bluetooth connected to my car stereo. Or try, bluetooth volume control from Playstore maybe?

I am using JetAudio and optimization is turned off. Tried volume control you suggested, but it makes no difference. Sound is still messed up.
I use Shuttle as music player, bare in mind that every recording has a different mastering approach, thus volume levelling could be varied, especially on first pressed of classic records. Usually I am amplifying low signal wave records manually. But to keep away from such trouble, I suggest Spotify since it has normalizing feature, or turn on this feature if it is available in your music player.

I use poweramp.
It really help you. Give a try.
Do not use any third party equalizer app with Poweramp,use it's own eq .
I use CM's audiofx since it has somewhat subtle enhancement, aggressive sound tweak is nice but after 10 minutes or so, it tends to hurt my (old) ears. So most of the time I turn off EQ in order to preserve original sound, not that always works though, especially when it comes to mainstream records.

I am listening to my offline archive, not using Spotify etc. There is no way how the source file is affected - maybe one, but hundreds of tracks? Nope. If I have 67% volume or less set in my phone, sound is fine (but overall volume is low, since stock audio has no other amplifier. But when phone is set to 100%, no matter how loud I set car audio, sound gets wavy then. No other phone ever had this issue, I tried direct comparison as well.
I managed to do some test for a whole album on my way home, I could declare the volume level as well as connection was quite stable with no apparent bitrate drop. As a matter of fact it's superior than realme 2 pro which was suck big time in audio department. Although it is no comparison to my now dead lg V10, at this price point I can safely say I'm quite satisfied. The stereo is neither after market nor android auto.

Thank you for your efforts, so it looks like this is issue on my side. I already contacted seller and I will apply for warranty claim, because there's nothing more I can do.

I also have the same problem with my Bluetooth headphones (Sony WH CH400) which does not happen on my Redmi 3S (PE 9).
Songs can't hit the high frequencies and sound gets lowered down.
I googled and apparently its the stock Bluetooth stack that doesn't let the bitrate go above certain amount and needs some patching which Asus may not do.

@Junglista what did you do? found any workaround?

Not yet, I read briefly the forum you advised, but I need to dig in a bit more. Anyway, even this the closest cause, I don't believe that this is issue is bitrate related (but I may be wrong). I still can hear high frequencies in music, but when bassy part comes in, it's like someone turns higher frequencies volume down, so you can hardly hear them. And when bass is gone, volume rises again to "match" volume of lower frequencies. I still did not apply for warranty claim, because according to the forum you posted, I don't want to give up early and try patching the stack (if I will be able to somehow). Nevertheless, I know exactly what reply I would receive after 30 days at after sales service - issue was not found.

Hey! Literally i have the same problem. I have the same phone 4 gb variant. I previously used a phone with dolby and now this phone sucks. I think every phone unit has the same problem.

I've requested a developer to implement this in his rom. Let's wait and hope the issue to be addressed by our amazing community, else our only hope is Asus Pie update.
PS. I have the exact issue, maybe I explained poorly. lol.

I've reported the bug on ZenTalk. I encourage everyone to report there too because it should be Asus' duty to fix this bug on stock rom.

Hey i found a way to tweak up things. The new omni player is on xda. It has a setting called output method. Select the OPEN SL ES. .ur problem will be solved.
