Distorted audio output from the headphone jack? - Xiaomi Redmi Note 5 Pro Questions & Answers

hello, I recently bought my note 5 pro, and it's been almost 10 days, worked fine for a couple of days but now whenever there is a word starting with the letter 's' or something similar the audio gets really distorted and has a crackling effect, I've used different earphones, tried different auido/video files it still happens
sometimes it randomly fixes and I get normal music, but most of the time I still get the distorted sound, is this a hardware issue with the headphone jack or a software thing? I'm using the latest stable 9.5 miui update. (updated via OTA)

Same here...

Once 9.5.x came, this sound problem is here. There is distortion in the highs, and changing the enhancement head sharpens it too some extent but not everything. 9.2.x was perfect. And present 10.0.0.x is better but not completely resolved.
I believe its a software bug or incorrect tuning.

I had the same issue in MIUI.... After changing to lineage it was fixed.

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

VS985 CM13 Audio Issue and Other General Questions

I have the latest version of CM13 on my Verizon LG G3. I don't remember when exactly this started, but it was recent. Any audio through the headphone jack makes strange noises. It started out at as white noise, very quiet, and as far as I could tell, only around when audio was not playing. Now it has progressed to being quite a bit louder, with the most annoying addition being the crackling/distortion/chirping sound that plays along with any audio, even louder than the audio when above 3 clicks of volume. It sounds very similar to a blown transducer in my earbuds or headphones. That noise switches ears at random, though never during listening. There is also an extremely loud popping noise when I turn the equalizer on or off. I have fresh installed CM13 and that didn't help. I know all of this is an issue with CM13 because I tried two other ROMs today, the latest version of Skydragon and XenonHD, the former lollipop and the latter marshmallow, and neither made those noises. (Neither of which I can use by the way, because I couldn't get either to realize I had a SIM card). I also tried all of the same headphones on other devices, and no noise. I'm open to either a fix for the audio issue, a fix for either of those other two ROMs so that I can just switch to one of those, or even a third ROM you know that actually works, but I'd like best to fix CM13. Aside from all that, Mortal Kombat X runs really laggy on my phone. How could I get it to run better? I score 47,000 on the new Antutu, what is the highest possible with my device? I don't want to get into overclocking, because the game already near melts my phone after a while and eats battery, but I'd be interested in hearing about what's possible with it anyway, along with other methods of speeding up. I've also been interested in dialing screen resolution down to 720p, which would help the problem and save battery, but I haven't been able to find a method that works. Thanks for reading if you got this far!
I'm having the same issue.
Fresh install of cm13. Only when the audio Is playing, and every time I start and stop the audio, it makes a loud pop.
This is a software issue, is there a fix soon?

No idea, that's what I'm asking. I fresh installed too. I have a really loud pop when turning on or off the equalizer, which I forgot to mention.
I've had the headphone issue for at least a few weeks on the CM13 nightlies. Flashing the 777 kernel (R22) fixes it for me, so it must me an issue in the CM13 kernel.

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

Problem with troubleshooting

I'v got problem with my N7100. It's custom rom and rooted, but problem seems to appear in different roms so I think it may be coused by hardware. Firstly I had the problem with sound, no sound during calls, broken headphone jack and random noises from bottom speaker. I replaced the call speaker module for new but probably not original one. But I still had random noises like cracking from big speaker. So I replaced it for one from another phone. Now I see that when I start the phone everything is okay, but after about 30 min sometimes less, sometimes more like an hour, the sound in both speakers is gone, and phone is either very very slow, almost like one operation per few seconds (YT videos crush when I tried to check the sound), or rarely acts very fast, and YT videos play at seems like 2x speed but still with no sound. Now I have no idea what's cousing these and how to fix it. Please help.
Specs:
Not original battery but phone show it's good 3,9mV
Kernel: 3.0.101-Haxynox-g8cd0810
System: 13.0-20160907-UNOFFICIAL-n7100

Audio problem on LinOS 18.1

Hi, there!
I'm having an issue with audio on LineageOS 18.1. Whenever any audio is played through the phone's speaker (videos, music), the material pauses after 5-10 seconds and when someone calls me or the alarm goes off, the sound is interrupted every 4 seconds. When I connect Bluetooth headphones, videos and music play without any problem. I had a similar issue with MIUI 12.5, then I switched to MIUI 12 and the problem disappeared.
At that time, I thought it was a software problem, but now I'm confused. Where should I look for the cause of the problem? Is it software or hardware related?
I would appreciate any tips.
I was having increasingly bigger audio problems on LinOS 18.1 (including complete loss of sound through BT), so I upgraded to LinOS 20. The problems still persist, with varying intensity. I tried using the 'Disable Headphone' application, but it didn't help either. Am I understanding correctly that the audio/BT on the phone's motherboard is malfunctioning?
