Hello , how are you? First, sorry for my english.
I need help, and I think that you would help me. I have a G3, and I've noticed that the earphones are making a noise when a sound is emitted. I've noticed too that this happen only in Lollipop ROMS (stock based).
I've installed Kit Kat and CM12 baseds and the noise doesn't appears. I already installed via Flash Tools and TWRP, with all wipes, but the noise persists. I've noticed the noise after I've installed the app Sound booster for G3.
I dont think that is hardware, because in Kit Kat and CM12 works perfectly. The noise happens too in all sounds of system (including music, video).
I've tested with more than one earphone. And before installing the app to boost the sound, it worked perfectly.
The noise doesn't happens in speaker.
Can you help me please?
I have this little noise too, but i note that it happens only when charging. Disappears when not charging. Probably an interference. Between earphone plug and charge
It's a fairly common lollipop occurrence. It happens in other devices too...

I've just noticed additional noise whilst music is playing (on top of the beeps when plugging in and hiss whilst no sound is playing). This noise is best describable as unwanted distortion on sound of particular amplitude, though a quick experiment just now makes me wonder whether the hardware design is bad. (AIUI G3 audio's handled by the Snapdragon MSM8975AC SOC, unlike my old Samsung S3 LTE which had a discrete Wolfson DAC).
This problem is also VERY audible on the bundled LD "QuadBeat 2" headphones, in both ears at various points. I'll see if I can get a recording of it.
Methodology:
I loaded the "Wave" signal generator app and tested various volumes - noise is evident at particular amplitudes. I set the variables thus: a 100 Hz tone, 30 seconds duration, varying amplitudes. Finally set Wave amplitude to 0.02, turned the device volume to max and listened to try and ascertain whether this noise was being introduced by the chipset or the Android OS.
Results:
There's very noticeable 'fuzz' and unpleasant distortion in the left channel, which goes away both under and over a particular amplitude threshold -- which leaves you with an annoying band of amplitude where you will always have additional noise overlaid onto the sound.
Frustratingly, this is often in fade-outs or quiet passages of songs where you're listening most intently. It also renders the G3 useless for any kind of analytical or accurate audio output, a crying shame. My Google Fu is lacking too, because I didn't see this thread before buying mine... I wonder if installing CM12 might fix it?
Unless this is a problem with the stock kernels and the way they handle audio output, I'm becoming concerned that this handset is faulty by design and I'm going to have to swap for another make. Until it died, my old S3 had great audio capabilities, and a nice chipset to boot!
I've sent a customer service request to LG specifically about this. Here's what I wrote:
I'm experiencing significant audio problems with my new G3 handset.
When headphones are plugged in with no audio playing, I hear two beeps in the left channel. Then, a low level - but constant hissing - in the left channel, until the sound chip is initialised to play audio. The right channel makes occasional warbly, 'squeaky' noise, seemingly modulating with CPU activity.
Also, since updating at the weekend to Android 5.0 Lollipop (OTA via the LG Software Update process), I have noticed that whilst playing any audio, if I adjust the device volume to around 50%, additional noise is introduced into the signal chain (audible as a dithered 'fuzz' over the audio content).
I have tested with various pairs of professional headphones (I am a qualified sound engineer) and the problems are present throughout. I am concerned that these are significant design flaws. Please advise if a software fix is available, and whether these are known issues with this handset.

I have found a workaround for this
I have tested 3 LG D855 and all of them have noise/static/high-freq leak from the processor out to the headphones. It might be a faulty design for the headphones amplification stage for headphones (when the headphones logo appears on the status bar). However, when using line level output (the jack appears on the status bar) the problem does not reproduce.
Therefore the workaround I've found is to trick the phone into line level output mode and then plug the headphones. To do this you need to plug in a 3.5mm jack extensor or a 2-to-1 3.5mm Y-adapter with no load, that's it, with nothing connected to it. At that moment, the phone will activate the line level output mode. Only after that you will connect the headphones, and you'll see there are no artifacts on the audio.
That being said, I'm not sure this will work with all kind of headphones as I have only tried with mines that are low-impedance ones, but on those it works perfectly. To be checked if the level of the signal in line mode is enough to drive other headphones.
In any case, it is a shame this happens with a high-end and expensive smartphone. I was hopping this will be fixed in a newer hardware revision but I got two replacements of mine and no luck. I have read somewhere this might be a flaw in Snapdragon 801, as it integrates completely the signal routings but isolates badly highfreq noise from processor stages, etc. etc. but I do not remember where I did read it unfortunately.
I hope this helps!
After update (probably the problem was before update too, but after buying I did update almost at once) I noticed that speaker below are the same loudness. But speakers on the top of device are very, very quiet. Do all have the same problem?
I did not check the loudness of the speakers separately, but I have experienced a problem that might be related. If I lower the volume to one of the two lowest levels, there are dropouts on the audio when watching a video. Do you experience the same problem?

What application do you use? Where do you see "one of the two lowest levels"?Make a screenshot of the situation when you hear dropouts, please.
Also check speakers separately by increasing volume to the maximum and putting your pointer fingers of each hand on 2 speakers on the bottom of the tablet. Then you will be able to hear only two speakers on the top.

It's happening in different apps, like Amazon Prime Video and South Park for example. By "one of the two lowest levels" I mean: Lower the system media volume to mute, then raise it by 1 -> lowest level; raise it by 1 again -> second lowest level.
There are also no specific situations in which the dropouts seem to happen. The dropouts are usually just 2 to 3 seconds long. It sounds as if the sound is dampened.
Thanks, I will check the speakers separately later today. I don't have the tablet with me at the moment.

I just tried playing on the "level 2" loop video with MX Player and didn't hear any dropouts. I cannot confirm the problem on my device.
Please. let me know the situation with two speakers on the top. Do they produce any sound? If they do what is the level of volume comparatively with the ones on the bottom? My speakers on the top is almost quiet. If I cover two speaker on the bottom with fingers or put the tablet on my skin on my laps (knees) I can hardly hear two upper speakers. Please, confirm: is it the situation of all devices M2-A01L?
yes that was what i was thinking

The two upper speaker seem to work correctly on my device. The volume of the right one is a bit lower, and seems a bit distorted, but both of them produce sound when I cover the lower two speakers. The lower two are louder, but that was expected.
I also realised that I'm on a different firmware version than you. Mine is M2-A01LV100R001C100B006

As I said before, the volume on the upper speakers is just a bit lower than the volume of the lower ones. But I can hear them perfectly fine when covering the two lower speakers.
my upper speakers were working loud and clear yesterday. today im pretty sure they are either not working or so low in volume that i cant hear them over the lower ones. Any ideas or suggestions? i did uninstall the harman kardon audio demo app.
I recently purchased a pair of Bluetooth headphones. They connect fine, but with the volume on max, they aren't very loud. I have used some Bluetooth headphone in the past and I had the same issues but I figured it was just those headphones. However, when I connected them to my iPad and turned it up, the were almost unbearably loud. Much louder than on my Pixel.
Anyone has that issue and been able to resolve it?
I did try disabling absolute volume but that didn't do anything.
My pixel is stock and not rooted.
I have three sets of BT headphones and all I run at volume lever 8-10. Max level would hurt my ears. Sounds like you have a hardware defect, likely the BT radio. RMA that thing.

Not necessarily. I've seen a video that someone was reviewing a pair of BT headsets and the Pixel 2 XL did have a lower output than the iPhone. I wouldn't be surprised if your BT headphones would be even louder on an iPhone too. Those and mine just happened to be loud enough for us but we don't know any better because we don't connect them to an iPhone.

I don't have that issue with my studio beats. Them things are very very loud on my pixel. I could put it to Max volume have the beats just hanging around my neck and you can hear everything perfectly that's how loud it is.
A few questions to help troubleshoot:
1. What BT headphones are these?
2. Do you have developer options enabled? If so, have you changed any BT codec settings there? If not, enable developer options and test various BT settings, based on the recommended connection for your headphones
I have a set of blueant pump airs and they are heaps loud - i can't go past 50% on my phone otherwise it'll do some serious damage.
After a RMA, I received a replacement Pixel 2 XL and noticed the speakers sound different. The bottom (right) speaker has more bass whilst the top (left) speaker lacks it. This is noticeable all the time for me. When I cover the speakers with my thumbs to identify the issue more, the top speaker sounds very different for vocals, drums and guitars. I'm not sure if this is normal for this phone as my RMA was for another issue with the top speaker so I am wondering if this is normal. I have read people saying the top speaker is quieter and a few with this issue but I'm wondering if it's an issue that can be resolved through another RMA or if it's normal.
It would help if people with Pixel 2 XL's test their phone speakers to see if they experience what I do. A good left right speaker test is https://youtu.be/hTvJoYnpeRQ and when you rotate your phone, the left and right speakers should flip and the audio saying left should have more bass as the phone flips the channels. It would also be nice if you would check with music to see more clearly.
All in all, should the speakers sound different or should they sound the same?
Thanks.
Wow never noticed that before yes the bottom speaker has more bass but both sound good. Probably an equalizer thing top is set for best speaking quality.

I think they're supposed to be that way. Mine does the same thing, unless be both have bad ones lol.
My one does the same thing - I was aware of it but your link made it pretty noticeable though. I don't use the speakers often so not a big deal for me.
Thanks for the help guys. Funny how no review channels talk about this.
I may be wrong, but I believe the bottom speaker is slightly larger. I recall seeing that on a teardown video/article.
My USB adapter
Long ago my pixel speakers worked just fine until one day I decided to play some music,and plugged and unplugged my usb adaptader and after that my speakers got damaged, I've tried hard reset and the problem still remains till this day.
Is anyone else getting an audio crackle when tapping the mic icon for voice typing? I remember this was fixed through software on my Pixel 2xl years back. It basically pops, sounds like it's clipping. VERY annoying.
Great...
Google still can't provide proper speaker and mic since Nexus 4. How many years has it been now they been providing worst audio and mic performance?

Did a factory reset to see. The microphone in google own messaging app didn't seem to crackle, but through Textra it did.
No crackle for me even on max volume.
What I did notice is that the stereo speaks are imbalanced in terms of volume. The selfie camera side speaker sounds way more "muted" than the charger side speaker.

Agreed. MAYBE the volume levels are the same on both sides, but the selfie side definitely SOUNDS different. I also dislike the way notifications sound. It sounds like it's coming from the back of the phone going away from me, making it sound like it's coming from a different phone a couple feet away from me.

Audio balance has always been an issue with Pixel phones, although they made a change to the series 5 which boosted the ear piece one was called adpative sound, maybe it works as well for 6

I'm not entirely sure there are speakers there. I can't find a teardown video yet.

Have you actually got the phone? All I've seen you do is comment after comment about how rubbish it is but nothing from you directly?
If you hate it so much don't get one.
No crackle for me. I use the mic often and play podcasts through the speakers of the day. The speakers are good, clear and can get loud if ineed them to.
The popping/crackling sound is happening on my pixel 6 non-pro model. If sound is playing and I either type or move around to different screens this happens. Looks like I am returning it.
So far I've only noticed pixel 6 pro speakers crackling playing genshin impact, easily heard on the main menu, but so far only noticed it in that specific title. Not while playing music or other games. So I'm hoping it's software related and I don't have defective hardware.
No crackle so far, just rocken Music.

Can you do a video for us, showcasing when this happens exactly and what kind of noise gets created?
Too late, returned the phone and earbuds. Between this, the lousy fingerprint reader and the phone randomly calling people, I am done.

I dont get how people get so many issues with phones lol... I've never had problems with any of my phones and I've had many...
My FP works 100% of the time, it is just a bit slower than the rest, but even then, just barely. I have a S21 Ultra in front of me right now and after testing both, I can definitely say that the S21 Ultra is a bit faster, the Pixel one is actually more accurate. I would prefer to have it in the back like previous models.
Having said that, if I did have those issues you described I would return it too.
I feel like it's a software thing, honestly. Because when i first setup myh device before I downloaded all the updates, there wasn't any audtio crackle at high/max volume. After I downloaded the updates, it's there slightly.
I don't have crackling or distortion, but I'm getting a good deal of sibilance from both speakers. Here is a definition of sibilance.
Sibilance
I listen to a lot of YouTube podcasts and videos and this is driving me crazy. I wanted to see if anyone else is having this problem before I see about returning the phone. Adaptive sound and balance control makes no difference.
I have a 6 Pro and have noticed crackling from bottom speaker since purchase when turning speaker on during phone calls. For me I otherwise really like the phone. I will be doing a repair or exchange once more phones become available.
I got my replacement brand new 6 pro, and now this one has distorted and crackling sound from the earpiece speaker. When i press the middle part of the screen anywhere.
I have turned off the adaptive audio, and I can hear the balance over blutooth changing. With one headset when listening to a mono podcast, you can hear the audio balance shifting randomly around.
With another bluetooth headset (my hearing aids), the balance starts out biased to the right, but the longer you listen the more it drifts to the left. Stopping and starting the audio stream immediately corrects it.
What is going on -- I have had every OnePlus Pro model since the 6, never had any issue like this.
Anyone have anything similar and or no how to fix? It is so annoying....
