Loss of Non-Call Audio on internal Speaker after update to B21 - ZTE Axon 7 Mini Questions & Answers

I recently upgraded to B21, and after a few hours media audio stopped working and notification audio has artifacts but these issues are only on the internal speaker but call audio still works. I've tried a factory reset, along with a variety of other debugging steps. Has anyone else had these issues?

Fortunately for me, my device is not showing any signs of this problem. If you've wiped the phone and the problem persists, I'd suggest contacting ZTE Support to see if they can help you out. You can also check out their 'Z-community' forums.
Good luck!

Sound randomly not working?

My sound will randomly stop working. This includes all sounds, such as the keyboard, selecting items on the homescreen, and watching movies or listening to music. A restart will usually solve the problem, but I have no idea what's causing it. Anyone else experiencing this or have a suggestion? Since a restart fixes it, I assume it is software related. I am running a fresh install of the most current EdenX ROM.
Anyone else?
I've flashed all the ROMs, used the unbricking procedure, wiped data and cache 1,000 times. Surely someone else is seeing this?
This has been happening to me as well, except that when my sound cuts out my Adam also emits a very loud static noise from the speakers. If I click things after that, it either makes the static noise or no noise at all. It has happened on every rom I've tried, including stock, and only a reboot will fix it. I emailed support and they asked me to send them a recording of the noise (I had offered to make them one to help them diagnose the issue).
I finally figured out what was causing this for me. I was restoring apps using Titanum Backup and the backup from my Android phone. There was something in there that didn't play well with the Adam, so it's not happening anymore since wiping everything and installing each app one by one.

No sound after flashing viper4Android

After flashing viper4android, the speakers are unable to produce sound of any sort. I tried flashing the factory image, and uninstalling the viper driver, but nothing seems to work. Any ideas?
I have the same problem. I can only get sound/video when headphones are plugged in. This happened to me right after installing V4A, I've been frantically searching and haven't found a solution yet.
Edit: Unrooting and flashing stock worked for me. Hope it works for everyone else!
i had the same problem this morning, i went back to stock and no luck, reflash pure nexus and vendor and still no sound at all, i wasn"t able to call, watch youtube videos, play music, not even able to take pictures and videos. ..
i call costumer service and they told me it was a hardware issue , so they send me a new phone,
Same here, getting the phone replaced by google.

Audio randomly cutting out S7 edge

I am experiencing random cut outs of audio during media playback through the speaker. Bluetooth and headset working fine. Notifications and other sounds working fine. Mainly during video playback, streaming and video stored on device, the sound plays for a few seconds then cuts out. I didn't have this issue before the most recent OTA update. I have tried factory resets, rebooting, wiping cache, even custom roms. Does anyone else have this issue? What is the solution?
I have the same issue as you. GS7 Edge Verizon. I can't find any solutions out there yet :crying:
Same issue. The only thing that I can add is that when the speaker cuts out, if I switch to phone, make a call, and then put the call on speakerphone, then hang up, the problem is fixed for a few minutes.
Does anyone have a solution for this? Surely its a common issue. Unless my phone is on charge I can't use apps like spotify, listen to podcasts or radio unless I keep the screen on.
Any luck?
I have the issue on a sm-g930F. Samsung support just says i should send them my device but thats not my plan. I called them and sayed i want a update of the firmware but they refused me and just sayed i have to send it to them because they can not make a update without my device is seen. I really hope someone sends his device to them that we can get a new firmware . Iam on android 7.0 official samsung update but this bug is in 6.0 the same .
Anyways i need a soöution for this. Its a softwarebug i know, because nexus 6p users and nexus 5 users expirienced the same ****in error. Please help out.!!!
I was experiencing audio pause or stopping after an OTA upgrade to Nougat on my stock S7 Edge Duo (G935FD), when using Pocket Casts podcast app to play files stored locally on internal memory. This seemed to happen primarily when using wired headphones or bluetooth speaker, and some minutes after the phone screen turned off.
I tried wiping the app cache, reinstalling the app, wiping phone cache, full phone wipe, reinstall stock Nougat via ODIN, TWRP & rooting phone, disabling Samsung App Power Saving via Titanium Backup (com.samsung.android.sm / com.samsung.android.devicesecurity). Only when I booted into SAFE MODE did the problem go away. So I used TB to disable pretty much everything I could recognise as an app I had installed.
Eventually, after much tinkering I seem to have narrowed it down to some combination of Quick Connect, Google Chrome and Android System Webview. I have disabled QC and Chrome and I no longer have any audio issues. When I unfreeze/freeze Chrome or Android System Webview I get an audio issue as the app freezes/unfreezes.
I had same problem and ı thought this problem can be related to an app ı installed. And it was. When i uninstalled Sputnik news. My problem had gone. If u have it, uninstal. If u dont have, may be one of other app causes. Try uninstalling each app, and find the app causes this problem

No Audio Output from 6P

Hey guys! I am not able to listen to music or open youtube videos or even do anything related to output of audio of my phone. On Google play music, I get "Couldnt pay tax requested" and on youtube I get playback error. I am not able to make calls as well.
I have flashed numerous images and the issue still persists. If anyone could guide me towards the right direction that would be great.
I bought the phone 7 months ago and suddenly this incident took place. I was running stock 7.1.2 when this happened by the way
Thank you for the help.
First of all, 7.1.2 is a Beta stage not a release.
Second, If you can have sounds on other options such as ringtones and so on, then it is an OS issue and a clean flash might solve it.

Thank you for the reply.
No sound from Ringtone as well. Like no audio is playing on my phone at the moment.

So how can you tell if it isn't a hardware issue and not Android problem?
I haven't heard of what you are describing as being a known bug in 7.1.2. You can try a factory restore but personally I would do a clean flash of the latest stable Google image and see if it fixes your problem. And I would use the flash-all.bat command like Google suggests rather than flash all the parts individually like the Heisenberg guide on XDA tells you to do. I don't suppose you are running any audio mods on your phone? And you checked the obvious? Your phone isn't in Airplane Mode, Do Not Disturb isn't activated, sound shows the various volume levels aren't at 0?
Having same issue, no audio at all from speakers, cant play youtube / googleplay music or videos, headphone jack does not work eighter, wont even detect the headphones, soft reset/ hard reset wont work, havent tryed out rooting and changing rom or reverting from 8.0 (currently running), apart form audio everything works fine, im still trying to figure out warranty as its still in its period, but without proof of purchase they are beeing jerks so far, so im rooted with some ideas is ive had previous experiences with phones, might it be possible for audio drivers to go missing or messed up? or should i take it to a repair shop and see how much theyll ask for it? or shuld i just upgrade to something better and let this brave hero die alone, maybe use as hotspot in my car haha

Audio Crashing

I apologize if this ends up being long winded, I want to lay out all the details.
So I recently purchased (what I had believed to be) second hand Nexus 6P. It is in perfect physical condition however, no signs of ever being used. Battery is great, performance is great, speakers are great, camera amazing, and screen is perfect. However two odd things started to occur which I believe stems from the same issue. When hanging up phone calls the hanging up process would hang for a long while and either eventually hang up or the system would soft reboot. After reboot notifications are still set to priority only "call management", although it is easy to adjust and bring it out of that. However no audio/mic works at all (Play Music and YouTube give an error that they cannot play). No audio from speaker, or from headphone jack. I could however connect to a Bluetooth speaker and audio plays just fine. I then went to do a proper shutdown of the phone (using the power button menu), and when I manually booted it back up all audio works find again. I plug in headphones and start listening to music on Play Music. After a while however, playback fails and all the audio on the phone is once again dead...queue soft reboot. And repeat the whole process again. If I'm listening to headphones and I do anything to activate the microphone, audio crashes and go through the whole process again.
So I decided to make sure it was all up to date all the way to OTA 7.1.2. Once I did and I tested, the same issues above occurred over time. So then I thought maybe if I used Nexus Root Toolkit and did a full manual wipe and reinstall of 7.1.2 factory image from Google. Phone issue initially went away, but audio playback through headphones persisted and eventually the phone issue manifested itself again.
Today I decided that I do a full wipe again and try and install Pure Nexus 7.1.2, non rooted with BeanGapps and vender image (following the entire process here to a T.) I have not been able to replicate phone issues, however the audio playback and headphones issues are easily repeatable.
TL;DR - So this leaves me with a few things;
1. I can use the phone by never connecting it to external audio source perfectly fine, no problems at all.
2. Phones calls may sometimes get stuck at hanging up, and the result is a crashed audio system.
3. The only way to temporarily solve this issues is to shutdown via holding down lock button and Power-off using the menu that appears. And then manually starting the phone back up again.
So I'm not sure if this is a hardware or software issue. The fact that it persists between full wipes and reinstall of different roms makes me think it to be hardware. Although the temporarily fix of proper shutdown and manually start back up makes me think the OS/Kernal is somehow "clearing a buffer" or something in it's proper shutdown process. Which without doing leads to the audio system being completely down. Therefore on soft/dirty reboots the audio system is still down.
As an added bonus my sim card was a Micro SIM, before I opted to take the scissors to it instead of buying a nano sim. It works (so I thought), it just doesn't fit in the tray quite right. I tested recently with a proper nano sim from a different phone, and everything worked perfect. Then I swapped my franken sim back in and...it worked perfectly fine.
I did search for this issues in previous posts but all I could find was this. The issue (s)he describes is exactly the same issue as me, but his/her solution does not seemed to have worked. I am inclined to try doing a full wipe again and flashing completely stock older version though.
Any help, suggestions, etc are greatly appreciated. And thanks to the developers of Pure Nexus, it seems to be very polished and I'd love to use it daily driver.
Since you are having the issue after a clean install of stock and a clean install of Pure Nexus I don't see how it could be anything but a hardware issue. You could try to flash a custom kernel if you really think the kernel is an issue but I doubt that it will do much good. You could also try a clean flash of a different rom (I recommend Dirty Unicorns which is very smooth and stable) but again I doubt that it will do much good since you seem to have a hardware issue. You might have bad memory which is getting cleared when you reboot the phone.
I fear you may be correct. When you talk about bad memory, I don't want to misconstrud what your trying to say. Would there be a buffer for the DAC for example that is bad? Or do you mean the RAM or the flash memory itself?
It is very disappointing. This phone is perfect otherwise. I'd like another 6P, but I am concerned I then get one with battery issues.
