Buzz/Static/Noise with earphones - LG Optimus 2x

Hello,
using the earphones I noticed that it does a really annoying thing, in a situation with no audio in playback whenever you press something that is supposed to make a sound like open an app or menu navigation you hear a static buzz noise, like if the audio was "initialized" followed by an evident noise that stops after 2 seconds (unless soon after you press something else that makes a sound), that stops with an another buzz, corresponding to the audio being "closed"... so imagine what happens when you're surfing or exploring the phone with no music playing how annoying this is.
I'm worried because I read this is an android general problem and I'm planning buying a player based on android.
To make it simple it seems like instead of the earphones port being used constantly when you connect them it only sends an analog signal when a sound needs to be reproduced causing this constant buzzing. Is there a solution for this?
Using cm7 202

Hi,
I'm not really sure about this issue, but I do experience the same thing, im using modaco GR5 with stock kernel. This issue is there ever since I bought this phone.
I read somewhere in xda that the way LG assembled the hardware in o2x is not really good, even the crosstalk while using headphone is said to be one of the worst. The noise/buzz/static you are hearing, might be coming from electrical leaks that end up audible on the earphones you wear.
Cheers!

I noticed this since the first day I used the phone.
At first, I thought It was something with my earphones (Razer something), I tried the LG earphones that comes with the phone and the same "problem" happens, this is a little irritating.

Guess it's hardware.. Happens on CM7/VorkKernal and stock rom too.

It is extremely irritating

[Q] Horrible sounding audio

I was wondering if anyone else has been experiencing really bad audio quality on the captivate, or if anyone knows what might be causing it?
I tried looking for info but all i found was regarding bad audio on froyo.
Im running 2.1 JH3, and I had the problem with JF6. I was using pandora and it sounded horrible (with both roms). I tried some other audio from the web today and it still sounds bad. Any ideas?

Go into the settings for pandora and check the better audio quality box. I've noticed with out that pandora sucks

I tried that, and it isn't just with Pandora. This is the only thing making me miss my iPhone....
Is it like cracking and popping?

What I'm hearing, is that when I some music files, it sounds like it is really low quality. Like an mp3 compressed to 48k (or less). The singing in a song is hard to hear, it all just sounds muddled. Listening to music in the browser and Pandora both had this effect. I haven't loaded any mp3's yet (been busy learning and rooting, etc) but I have downloaded a few ringtones, and they don't seem to experience this issue.
Listening to Pandora has been both through the built in speaker, and the headphone jack to a speaker system. Horrible on both. Also, I was using Google's Listen to listen to the most recent episode of the Engadget Podcast, and with the volume all the way up on both the Captivate and the sound system, I still couldn't really hear it. I unplugged and listened to it over the phone's speaker, and it was audible enough to hear, although not at all loud, even at max volume.
Thanks a million for the links to those threads! I searched and searched and couldn't find anything relevant to my issue. Did you have prior knowledge of those threads, or did you find them by searching? If so, I'd like to know what keywords you used (if you don't mind). I'm always trying to improve my ability to help myself, so I'd appreciate it. It's late now, so I'm going to fully read those threads and try the fixes in each tomorrow. I'll report back. Also, I'll test my wife's Captivate to see if it has the same problem. **** it, I'll do it now.
Results: Pandora sounds fine through the internal speaker, when plugged into the speaker system (iPod dock w/aux in) it immediately sounds like ****. Perhaps the bad quality is only when plugged in, I might have just thought the internal speaker sounded bad because it's tiny. I'll retest my phone in the morning.
Well i just kinda stumbled onto the thread when i was looking to see the source of the crackling and popping I sometimes hear. Though you could scroll down to any page of a thread and see the tags associated with it.
And to me it honestly sounds like a singular issue with your captivate. The sound is loud and clear on mine. Even Pandora is fine for me
I did some more experimenting. At first I had hope about the headphones EQ fix, because I figured out that it only happens on audio that is plugged in to the ipod dock. When using a headphone to tape adapter in my older boom box, the audio sounds fine. I'm going to try switching out the cables and try the other input on the dock.
And, it happens on both mine and my wife's phone.
Thanks for the info!
OK, I'm an idiot. It was the 3.5mm cable (exacerbated by the samsung EQ issue). Thanks everyone for the help.

[Q] Bizarre issue with headset when plugged to PC

I'm of course talking about the stock headset that came shipped with the Galaxy S. The earphones work like a charm when plugged to the phone, but if I want to use them with my laptop, the sound I get is very distorted (it sounds like all the bass is minimized and speech is garbled).
The strange thing is that the sound output goes back to normal as long as I am holding the button on the headset. I want to know whether anyone else has had this problem and can help fix this problem.
I know this problem isn't exactly related to the phone, but I couldn't find anywhere else to seek a solution.
It is a known issue. Headsets for Galaxy have swapped ground and mic lines (in relevance to most common headsets), so this is the reason...
Yeh. Same layout as nokia n97 headsets. Annoying

[Q] Sound quirk - is this normal?

I bought a Galaxy Note a month or so ago. I'm not sure if this happened before the ICS update or if it came with it as it's still all a bit new. I'm wondering if the following behaviour is a fault (hardware or otherwise), is a setting that I can alter or if it "just is".
I use the Note a lot to play music especially at night as I'm going to sleep, when I have the Note on either the quietest volume setting or something close to it. I have noticed that when the volume level is low on quiet passages in the music it drops out altogether. This is quite noticable as any background hiss (on older recordings) drops to silent then comes back in again as the music approaches a louder passage. It does the same on video.
It can be quite annoying and very distracting. If I turn the volume up (past about half way on quieter, older recordings) the problem vanishes completly so it looks like an issue with the pre-amp or DAC?
I have tried different audio players and different headphones with no change. I have also tried playing music without headphones (using the in-built speaker) and think that does it also, although it's harder to tell.
The wierd thing is googling around I can't find anyone reporting the same problem, which makes me think I possibly have a fault. Any ideas? Could someone else with a Note on ICS try the same thing and report their findings?
Test is: find somewhere very quiet. Play some quiet music on the Note and turn the volume right down until it is barely audible with the earphone pressed in. Try different pieces of music and see if the sound drops out on quieter passages - for me, it does.

I found this happening on a fade out of a song (Bjork - Play Dead). On volume 1 the sound would cut out much earlier than on volume 2. It sounds like a classic noise reduction technique kicking in - designed to reduce hiss.
Not much pop music is mixed like this any more I don't think. You'd certainly notice it more on Classical music where the dynamic range is far greater than Pop.

Perfect - yes, that describes my problem. And yes, it is classical music where I find it most noticeable (especially older recordings which tend to be quieter with quite a bit of background hiss). I wonder if there is any way to diable the noise reduction...?
Appreciate your help. At least I now know I don't have a faulty device. Massive thanks.
By the way the best answer I have so far is to play on higher sound levels and use an set of headphones with an old style (non digital) volume control to bring the sound back down to a reasonable level at the earphonesd. Pretty poor solution really - had hoped for better from my lovely new Note.
+1 big problem for my...and now...not solutions...waiting...
I have this issue since Samsung replaced my mainboard. It happens on stock ICS and CM9. I haven't tried Gingerbread.
Could this be a hardware problem?
Is there any fix to this yet, this is exactly my problem, good tip about using an in-line headphone volume control though
The same bug. Please fix it somebody.
I too have this problem with my new Galaxy Note (ICS 4.0.4). I'd be interested to hear from any Note users that *do not* have this problem when playing back audio at low volumes. If you don't notice the audio completely dropping out, please list what version of Android you're running. Thanks!
I guess we need some more experimentation to see if it's a hardware or software issue (or both).

Hi,
I am quite sure this is a software bug. When my note was using gingerbread, it was OK. It started to behave this wasy after the (official) ICS upgrade. Some of my friends are using unofficial ROMs (4.0.3 or 4.0.4) and it is ok - I tested it. So my conclusion is that samsung put some software trying to reduce noise in low audio volume, but it's not working as it should be...
More people are stumbling upon this noise gate problem:
http://code.google.com/p/android/issues/detail?id=35861
http://forum.xda-developers.com/showthread.php?t=1717425
I experience it on ICS and also on CM9, only with headphones plugged in (not when listening to music via bluetooth on the Sony MW600).
It does not occur on Gingerbread, but I don't like to use that ROM as a daily driver...
Can anyone confirm if there are custom ROMS that do not have this behavior?
Or is there maybe some way to replace the ICS media playback service with the GB one?
Well, all ICS-based custom ROMs I've tried suffer the same irritating behavior.
And it also turns out that GB has the same kind of noise gate, but the threshold seems to be a lot lower and therefore it doesn't kick in that often.
But I've just installed a CM10 nightly, and that seems to solve the issue.
my 2 cents
I can confirm, that I have similar problem.
I have the problems only when watching movies. the sound just cuts off when the character stops speaking, so it cuts off the background sound.
I tried different kernels, ROMĀ“s... same problems on GB, ICS, CM9...
I have a hillBilly solution that works for me! When ever the sound cutting starts, I just change the volume for one level. The cutting will off course repeat... but it's indeed better than listen to the clipping...
For black clipping I use highest brightness and film screen mode. It does the trick for me...
But it just pisses me of when I realize that I have the phone with ****ty screen, sound and bricking danger...
wtf sammy... i just cant belive that i paid 540 eur for this, its sad

Just flashed latest PA, and its till there!
Im not an expert! Does anyone remember a background noise reduction option while making a call in GB??
I cant find it in ICS or PA. I think that this background noise redustion system is causing the cutting. It must be somehow connected.... im not an dev or anything but my gut tells me that this could be!
anyone?
Take care
DonLaDroid
OK all, let's figure out what ROMs don't have this problem, and start bugging the Devs to try to fix it on the others :laugh:
Well, I just noticed that the sound cut-off is also back on the unofficial 08/31 build of CM10. It was much less noticeable on the 08/28 build. :crying:
The difference between the two builds is a huge decrease in sound volume: build 08/28 was much louder than the latest one. Maybe the noise gate simply doesn't kick in so soon when the system volume is cranked up. You basically get the same effect when turning up the volume completely and turn it down with an inline analog control - as suggested by StarFishUK in post #3.
So my question would be what makes the volume louder on 08/28?
And how can I get that 'cranked up volume' on newer CM10 builds or preferably on ICS roms? Any ideas?
By the way, I totally agree with your 2 cents DonLaDroid. I never had this much trouble with my old Dell Streak...
Haven't noticed this myself (CM10), but i've noticed something incredible annoying in CM builds, and that's when i'm listening to music with headsets and i'm increasing the volume, it seems that it's "missing" a couple of steps. So when i'm increasing the volume it'll go from 5 to 8 in one step, and not 1,2,3,4,5,6,7,8,
It should be: 0,1,2,3,4,5,6,7,8
But it is: 0,1,2,3,4,5,8
How to test this problem. ..
Go to a quiet room.
Set audio level to one (one click up from silence)
Play some music with soft passages.
For me, the sound shuts off during quiet audio for speaker and wired headset. Note that this isn't simply an absence of sound. The sound turns off then suddenly starts again in the middle of a louder passage.
Bluetooth doesn't have the problem.
A gentleman on one of the Kernel threads believes this may be a hardware issue. The sound clips to cover noise from the speaker.
All, it seems that this is a "feature" of our phone. We will need to contact Samsung for the word on if this is a hardware issue or of it can be fixed via software. Right now it seems this happens in all ROMs, Touchwiz or AOSP.
Workaround is to use Bluetooth or a wired headset with an analog volume control.

Speakerphone SOFTWARE "Issue?"

Hey guys, I've noticed a weird bug with stock 4.2.1 on my Nexus 4, and was wondering if anyone is experiencing the same thing. If not, then perhaps it is the hardware and not the software, but the nature of this bug has lead me to believe it is software-related.
Let me first say, right off the bat, that I have had no other issues with my phone, and that when I play games or watch movies, the volume is loud, clear, crisp--just all around excellent. However, when I use the speakerphone on a call, it seems to be... quieter than everything else. So I tried playing around with it, and discovered something interesting.
The next time you're in a call, put it on speakerphone. Note how loud it sounds to you. Then, turn the volume down one notch, and then put it back up to the max volume again (I've only experimented with it being at max already, then turning it down one notch, and then back up).
Does it sound WAY louder? And does it sound distorted, almost overblown? Why would it be like that during a call, and why would adjusting the volume down and then back up again have such a result if it was NOT software related? And, furthermore, why would it be blown out and distorted here where as for everything else it sounds superb?
Let me know your thoughts--maybe I need to RMA? I got this one at T-Mobile (I didn't have to pay the equipment installment due to my current plan, so it was cheaper to buy it @ $200 from them).
Thanks!
Same Here .. I believed it was the only with this problem since no one had said.
I think is Software Issue.
Yeah I noticed that no one had mentioned this, but I believe if it's software then it must be affecting everyone. At least, it should be affecting stock users. I guess I noticed this sooner because I use speaker phone when I'm driving in the car, since my ragtag bluetooth receiver that outputs through a tape that's plugged into it and inserted into the tape deck only transmits music and notifications, not calls--for some reason--over the car speakers. Just got sick of plugging into the phones headphone jack every time I got in and out of the car! lol

See but mine doesn't crackle or do any of that stuff during calls or anything else. And it's not blown out sounding during anything other than calls where I have lowered the volume and then put it back up to max right after. I don't think the problem is the same as it is here, it just seems similar, for sure.
Also, when not on speaker phone, the in call volume is perfect and without issue. It's limited to specifically what I mentioned in the original post.
Thanks for the reply, but I'm talking about it being overtly loud and only being so when adjusting the volume down and back up to max, and that prior to that, the volume is just a bit on the quiet side at the maximum. Not crackling/popping/etc!
cool..sorry about that.
Exact same situation with me.little buzz while on call nothing else.

Galaxy Note 5- Audio Glitches When Listening To Music

Audio issue - please help
I just bought the note 5 from tmobile 4 days ago. It's an amazing phone, however I am having an issue with the audio. I'm not sure if it's something internal or if my earphones are broken. Basically when I play music through my earphones, the song plays normally. But at random moments I can hear random noises. The noises come in at random moments in the song.
I noticed this pretty soon, but didn't make much of it at first. Now, on my bus ride to school it's finally gotten to a point where I can't take it. The music gets warped for like a millisecond, but that happening multiple times in a song just got a bit too much.
I have not checked if this happens when using the speakers or using another pair of earphones. I'm using the pair that came in the box. As I said I'm on the bus, so I can't blast music through my speakers. However I was playing music yesterday through speakers in my room and now that I think about it I didn't notice any warping. When I get to school I'll borrow someone's earphones to see if my pair is just broken.
But yeah are any of you having this problem? It's a big deal cause I listen to music a lot through my earphones.
Love your thread, man. This happened to me too but I wasn't 100% sure and I couldn't reproduce it. Now I know it's a problem. I just hope it's on everyone's Note5 too because then it would be a software problem that'll disappear soon. Otherwise we may have to go for exchanges. What ROM are you on? I'm 100% stock N920CXXU1AOH2.

I just registered to say I'm having the same exact issue when listening to music through the headphone jack no matter if I use headphones or the Aux input in my car. I hope this is a software issue and gets fixed soon.
I haven't seen this issue yet but I havent been listening to much music lately anyway. Will check it and get back. I am more concerned about the S-Pen sensitivity issue. Also started a thread for it here
http://forum.xda-developers.com/note5/help/samsung-galaxy-note-5-s-pen-sensitivity-t3205683
It was happening to me on stock not rooted with Bluetooth and pandora. It was only happening with WiFi on but I haven't noticed it since I'm rooted on custom kernel and rom
I think it happens only on certain frequencies because when I listen to podcasts I never have the issue.
Yes I'm having the same problem when playing music through the auxiliary port or the phone's speaker it's self. Randomly sounds like someone has the hiccups in the background. Have you found a fix?

From what I've come across, it seems like an issue with VBR MP3 files. I was able to fix it using Poweramp as my music player, as it uses a different audio processor than the stock Samsung one.
Also, the update released a few weeks ago also seems to have fixed the issue.
I had the same issue in the older firmware of my Note 5 920I. The latest update OJD fixes the problem. Not facing anymore glitches now. It's definitely a software bug and has been solved by Samsung. Please update your device normally. No root required.
Use Don't Pause
There's an app called don't pause. What it does is when youre listening to streaming music that when you get a notification that you wont get the gap in space (pause) in the music. The paid version removes ads. Ive been using it since the KitKat days with my Note 3 and it works well.
Radio
can I add radio app to not 5 ?
I face audio prob too. Note5 no root, stock 5.1.1.
When I feed digital signal to ext. dac, if use Scale up 385khz then pop and click happen (i use Neutronmp).
When scale up 88khz this phenomenon reduce and when no scale up used, sound is smooth.
Also hf player upscale to 192khz is ok.
Note2 and Lenovo A7-30 and S4 is okay when do the same thing with same neutronmp version.
No solution till now
Depending on if the issue is with your actual audio or if its coming from the music player will be two different things. I always recommend doing a quick restart on your phone or trying to leave it off for a little bit if its having any issues. Usually this will work if there is an overheating issue. You should also try doing an update which can fix problems in the software. If its with your actual music player then these are some of the best music players for the galaxy note 5 hands down https://fliptroniks.com/best-music-app-for-galaxy-note-5/

Hey Guys,
I am also experiencing the same issue when listening to music via the headphone jack. Something that I noticed was, when the screen is switched on, it works perfectly. As the screen is switched off, the music gets warped and scratched.
Anyone found a solution for this problem?
