[Q] low sound output on headphones - ZenFone 2 Q&A, Help & Troubleshooting

when i listen to music on my zenfone ,maximum volume is very low also music lags when using other applications,tried reflashing the firmware and other headphones but that didnt work any one got any idea?

two ways to get higher music volume on ZF2:
1) Turn off the equalizer in Music, that seems to help.
2) Get some different earphones, the Asus bundled items are significantly quieter than any others that I have tried. **Sorry, I see that you have tried others, but keep trying, I use Skullcandy and Jays, and both are much better**
With regards to the sound lag (its not just Musisc, it happens with calls and other apps too) when multi-tasking, Asus has been made aware of this (see the "Audio Issues" thread on Zentalk forum), and may, or may not be working on a fix....
Some people say that turning off System Sounds in settings reduces the sound lag, but I can't say that it has helped me. This is the single bug that most annoys me with this phone.

tried updating music fx plugin that came preinstalled to a newer version it improved the sound output a little bit,thanx by the way.

I think latest update (V2.17.40.12_20150515) has fixed this issue... Please update and check as many users are reporting that the bug has been fixed...
Full change log:
1. Fix location picker crash issue when attaching location info by Messaging
2. Fix Live Wallpaper settings issue when in landscape mode
3. Improve Camera App overall stability
4. Reduce the occurrence of the issue that words sometimes fail to come out when typing
5. Shorten the required time of setup calls
6. Fix outgoing call problems when using back key
7. Fix "No SIM or SIM error" issue when calling the phone number starting with 911, 112
8. Improve image quality in detail.
9. Fixed the audio sound maybe lag when using headset
10. Improve signal bar stability
11. Fixed the interruptions mode issue.
12. Fixed flip cover cannot support some apps issue.

I'm on 2.19.40.20 and still have this annoying issue both on normal audio and speaker, which is always too quiet for any hands-free or outdoor use
Is there any workaround ? (rooted phone)
Do you think that Viper4android or whatever could help to raise the sound levels ?

(I own an Asus Zenfone 2E so I don't know if this will work with the Zenfone 2) I disabled (AudioWizard/com.asus.maxxaudio) and rebooted. Tada! Headphone output is a crap ton louder! Hope this helps! I also deleted the MusicFX plugin. Don't know which one of those worked but one of them certainly did!
This is what I disabled using NoBloat(Remove spaces) http: //i.imgur. com/NO7dvls.jpg?1

Having your headphones suddenly become more quiet than usual, whether it’s on both earbuds or just one, happens quite more often than you’d think. Before we discuss how to fix the problem of your headphones being so quiet, it’s important that we understand why it happens in the first place.
Here are the most common reasons why headphones become quiet:
Issue With the Plug or Socket (For Wired Headphones)
Issue With Connectivity (For Wireless Headsets)
Device Settings
Issue With the Audio File
Issue With the Headset Itself
Issue With the Ear

[Q] Sound problem: audio almosts mutes when music app loses screen focus

Hi. Having a problem with my Desire HD, which is rooted and CyanogenMod version 11-20140703-UNOFFICIAL-ace.
When using the headphone output as a "line out" to an external speaker in an audio app, such as Winamp, Mixcloud or TuneIn Radio, as soon as that app loses screen focus, e.g. going back to the home screen, the audio level drops to almost inaudible. The only way to cure it that I have found is to unplug and replug the audio cable and make sure the music app remains in screen focus.
Checking the Volume Control, the Media Volume is not reset, and turning it up to the maximum 15, still results in very feeble audio.
Not using any effects in DSP Manager.
The problem is not repeated if using a set of headphones or the phone's internal speaker.
Has anyone any idea what is causing this behaviour - is it likely to be software or hardware based? Any ideas?

Thanks dr.patron99. I haven't time to do a full wipe and reinstall right now, but I will report back in a few days, to see if that resolves the issue. Thanks for the pointer. Hopefully this will help out others too.
cm 11
flash recent nightly with full wipe and you're done! :silly:
device: Desire HD
rom: cm11 m8.1
recovery: 4ext 1.0.0.6 r3 build 8
hboot: 0.85
Workaround found!
Update: I did a full wipe, and replaced the old nightly with the more recent monthly 11-20140710-UNOFFICIAL-M8.1-ace, but the problem was still there for me. I will have to give the latest nightly a go, when I have the chance.
In the meantime, I found a WORKAROUND, by doing some extensive searching. I found a posting on that cures the problem for me on the XDA help forum for the Sprint Galaxy Note II. You have to sacrifice "OK Google" in Google Voice to achieve this.
The thread is here: http://forum.xda-developers.com/showthread.php?p=52533351 - and I have adapted the steps, which are a little different in my menus:
Home screen > Menu button > Settings > Voice > "OK Google" Detection > UNTICK the box for "From Google Search app" - the back out.
Fixes my sound problems on testing with TuneIn Radio Pro and Mixcloud. I hope this helps others too, who need a quick fix to the problem.
The issue seems to occur whenever the phone's internal mic is activated. The volume reduced to a very low level after using the Shazam music recognition app, which of course uses the mic.

Misterious audio problem

Hi everyone, before anyone complains I did search for the problem everywhere and found nothing so I decided to post it here.
I'm going straight to the point since the problem has been driving me mad for a long time.
The problem arises when I use the ear speaker after that the headphones output is totally distorted but not before. I've always managed to do a reboot and everything is back to normal until I use the ear speaker again and the problem comes back. Something strange is that I only notice the distortion on any headphones or headset but never with a speaker such as a bluetooth speaker or via aux cable to my car.
I changed the firmware to various versions (stock and custom), changed the kernel, changed some build.prop settings, disabled the equalizer apps, changed the music player, disabled the Nuplayer and the problem keeps coming back.
Any ideas ?
Thank you for reading, hope someone can help me I'd be really thankful.
No one had this problem ?

Yes, i had it many times also. I think sound doesn't distorts. The reason for that is audio effects (or any other effects) stops working so sound becomes plain with no bass and other things. Some times force stop audio effects works but reboot always.

I disagree because tried freezing the audio effects app and keeps happening, also the same installing Viper4Android

Audio randomly stops working

So not sure what exactly is the cause but one thing that sometimes will cause all audio to stop working is Google play music. Sometimes when I start playing music (device speakers, not Bluetooth or casted), the audio will stop working in a few seconds as if all volumes have been turned down but they're not. Music playback is still going. Verified that when this happens no other audio works as well.
In some cases the volume slider does nothing when adjusting (slider can be moved but no change in actual volume output level) and playback is still going and then audio is lost.
Playback control buttons in play music become unresponsive and eventual play music not responding message comes up. Closing app doesn't fix and still no audio in other apps or system. Restarting phone doesn't help either really. Only workaround I have found is to cast to Google home, play for a few seconds on there (which does work) and then disconnect and audio on device is functional again. Sometimes cast workaround works without reboot, otherwise the reboot is necessary.
Anyone dealing with this too? Things I should look into for suspect causes? Any help greatly appreciated.
Edit: now when audio stops on device, things become a bit more unresponsive throughout device and eventually the device restarts on own without the play music not responding message. Power off and restart options via power menu are unresponsive at this time too.

Hi Jason, I have the same issue. When I play music, the upper speaker stops emmiting audio and the lower one suddenly lowers its volume (but the audio is at full volume in the UI). the problem is that is random and also affect the phone app. so if this happen and someone call me I cant hear it.
do you resolve it?
let me know,
thanks

I tested in safe mode and verified it was not a hardware fault. I suspected it was something that happened when I was using substratum and applied a theme to Google play music. Factory reset was my only way to resolve.
Same issue here with my Pixel 2. I notice this behaviour after using a Bluetooth speaker, and disconnect from it. Sometime i lost Speaker and Microphone access to the phone. If i connect back to a bluetooth device, audio/mic in the bluetooth device work's fine.
I i reboot the phone, i regain access to speaker and MIC... until the next time i use a bluetooth speaker. I didn't notice this behaviour until last week. I have this pixel 2 phone for 2 month now.

Bluetooth audio stutter/skipping

This is incredibly frustrating. I had none of these issues with bluetooth on my S8+ whatsoever.
So one annoying thing that stood out was the bluetooth on this device. It keeps skipping and stuttering tracks whenever I play it on my Bose QuietComfort 35. It's normal on all my other wired cans but I usually use the QC35 alongside my phone during commutes.
Just to clarify, I'll list down all the "fixes" that I've tried. Obviously NONE of them fixed, or even alleviated the problem.
Cleared cache (this one just doesn't make sense imo)
Removed battery optimization on my music apps
Turned off WiFi & Bluetooth scanning
Switch Bluetooth audio codecs
Updated to 4.7.6
and PLEASE... if you DON'T have this problem, do NOT post how you DON'T HAVE THIS PROBLEM here, I'm looking for fixes, not jokes. Thank you.
I also have a QC35 and I don't have any issue but I post anyway
Joking aside I'm using 4.7.6 and my QC35's firmware is 1.3.4 and using the HBC codec.
What's your bose firmware ?
What do you use as a music player ? (I'm using the default Google Play music)
And what do you mean my "It's normal on all my other wired cans" ? Why would wired headphones have stutters ?

Everything's the same as you except I use PowerAmp as my music player and SoundCloud for streaming (both stutters/skips as well). I stated that I didn't have this problem on my wired headphones just to clarify.
I notice the problem most when I'm commuting and I have mobile data turned on. It went even more haywire when I downloaded something on Google Drive. Hopefully it gets addressed with Android Oreo and the official Bluetooth audio codecs being implemented.
Oh bad me I read the you said it was normal to have stutters while being red... Night too short.
I'll trying PowerAmp to see how it goes.

I think it has something to do more with the connections. It goes even bonkers when I'm moving around rather than laying in one place.

I think I saw somewhere it's an issue with aptx HD, try to force Bluetooth codec in advanced settings to aptx or sbc.

I just said that switching Bluetooth codecs didn't work.
I'm having Bluetooth quality issues as well, particularly crackling and skipping. I noticed that if I download a file while streaming the quality will drop dramatically and the audio stream will crackle like crazy. I have tried all three codecs in nougat to no avail.
Should I upgrade to Oreo to get this sorted? Do custom kernels cause issues with the quality?
Thanks.
OnePlus 5t, theOne 7.1.1 (stock basically), viper4arise and Dolby
Update: when into EX Kernel Manager (specifically under the misc I/O settings), and change the I/O from ZEN to FIOPS. Not once has the music stuttered since, though I have only tested on SBC. If I get more results I'll bring them in.
Please note - I am on blu_spark, and I honestly do think it may have been the cause of the bluetooth skips/scratchiness. I turned off Dolby Atmos and Viper just to be sure.
Latest Oreo Beta build. Stream bluetooth, Pandora, iHeart and talk on the hands free no problems here. Lexus CT200h vehicle.
Would really check your cars manufacturer website. Most have a section where you can download latest firmware to a USB and flash your car to ensure you have the latest bluetooth firmware.
Working flawlessly on my car.
Anyone have any experience with the Oreo update?
Since updating to 4.7.6, I've experienced the following issues:
despite being connected to a bluetooth device, sound still comes out of phone speakers
static/distortion for a few minutes when initially connected to my car (2017 Chevy SS)
Upon connecting to car bluetooth, randomly the phone will call my phone number
I can usually fix these issues by either going into airplane mode for a minute or two or rebooting. Sometimes, I have to do this multiple times.
I've cleared cache but made no difference and I don't want to have to factory reset after every single update. Is it possible to flash factory images without nuking your data? You can do this with Google's Nexus/Pixel factory images.
I've got a different problem with 8.1 and BT audio. After upgrading to android 8.1, suddenly my car audio system doesn't receive songs data (artist, song, album). It's just display "no title".
Does anyone encountered similar issue?

Ugh, exact same issue. I don't suppose you're using a car with a UConnect system in it? Dodge, Jeep? All those crappy brands?
I am able to make phone calls just fine but I can't stream audio to save my f**king life. This happened right after the upgrade to 8.1 and latest update did nothing to fix this nor did it mention the issue. Has Oneplus even acknowledged the issue?
Im actually having the same exact issue, with Uconnect on a 2017 Chrysler 300s. Bluetooth skipping and sounds like crap. Have tried pretty much everything so far and no fixes
this what happen to me ...bluetooth to speaker klipsch ... sometimes got crack sound ...i mean wtf
Has anyone been able to figure this out? I'm still experiencing issues as well. OP5T and QC35.
I've been working OP support for almost 2 months via email and the cannot figure out how to fix this for be BT CALLS sound terrible,
I'm having problems with Bluetooth in a ford fiesta 2015. The phone is on 8.1.0 stock, no root. The device itself connects to the car perfectly, but fails to download the phone book, and says I loose signal when trying to make a call. The device registers that I've asked to call a certain person but nothing else happens afterwards.
I didn't have this problem on 5.0.4

Random loud screeching/white noise when bluetooth is on?

Recently, my phone's started to randomly shriek with white noise and it scares me silly. I think I've narrowed it down to when bluetooth is enabled and playing music (spotify).
Has anyone ever encountered this issue or could suggest what solutions I can try out? I've rebooted my phone and I don't want to immediately jump to a factory reset quite yet.

I have an AT&T LG G8 running Android 10 (SW ver. G820UM20k.) I've also had this issue for some months now. However, while I have Spotify installed I am almost never using it; the noise occurs anyway.
My usage pattern when it occurs typically involves going between YouTube, Chrome, and Twitter apps, and occasionally other social media apps. Often happens when playing a video or audio in the background, but occasionally get the noise when dead silent in between apps too.
I've noted that if I stop what I'm doing when I hear it and immediately switch the audio path back to the phone (via the notification toggle,) the noise often occurs again but out of the phone speaker after a short time.
Now, I've not experienced any random noises the past couple of weeks, but haven't found a definite solution either. Searching the internet for "phone random static burst" or "phone making loud noise randomly" yields similar complaints going back the last few years, across different devices (and presumably Android versions.) Disabling/ force stopping Chrome was a more popular suggestion that came up, as well as fiddling with the Bluetooth codec in developer options. (I'd also suggest making sure all installed apps are updated, if the bug is indeed related to apps mishandling audio somehow.)
Given the range of system specs with these similar complaints, my hunch is the core issue may have to do with certain Bluetooth stack implementations just having problems in certain scenarios. FWIW I have my Bluetooth currently set to AVRCP 1.6 (Default is 1.4) and audio codec to SBC (Default is System Selection.) In months prior when I had the noise issue, these were set to default. My Bluetooth earbuds (Sony WF-1000XM3) prefer to default to AAC codec but do support SBC; I believe I haven't had the noise since forcing the system codec to be SBC only. If nothing else works, may be worth toggling that setting and hoping it fixes the noise. Good luck.
