[Q] Static / Engine whine only when no audio is playing - Galaxy Note 4 Q&A, Help & Troubleshooting

My Samsung Note 4 has fairly loud "static" that sounds like it's picking up the internal electronic noise (also slight engine whine when the engine is running) coming through the headphone line when plugged into USB power in my car.
This only occurs when there is no audio playing. As soon as any audio plays, the static/whine goes away 100%.
I would normally first troubleshoot other things besides the Note 4, however, I've used various other mobile devices in my car and they all have had zero noise.
This is using the AUX input in a 2007 Honda Civic via the headphone jack and powering it via a 12v cigarette adapter to 2A USB plug.
Anyone else experience this? It just seems very strange that it only happens when there is no audio playing and the fact that no other devices I've tried have this issue. (Various IOS devices and a Nexus 7 don't exhibit this problem)
Thanks for any suggestions!
Update: Swapped USB power adapters, USB cables of various brands including the OEM samsung cable and various audio cables with no change.
I've found that the noise is there with just the power hooked up. (engine off) The "static" changes as I use the device, so it appears it's picking up the internal electronics "noise".
It just really makes me thing it's not a hardware issue if the "noise/static" goes away as soon as any audio plays. Then a second or so after the audio stops, the static kicks in again. Not certain if I should exchange the device.
Update 2: After more googling, I see that others have had this same problem and as silly as it sounds, someone made an "Aux Noise Filter" application. I tried it and it did cut maybe 95% of the noise.
The app shows a date of Aug. 2013. Just seems silly that the problem has been going on this long??

[Q] Playback through Car aux connection

I play audio podcasts through car's aux in and just plug in the other end to my Focus's headphone jack. I have noticed that many times the podcast suddenly lowers volume to nearly inaudible levels and happens intermittently.
Once the problem shows up if I
- play songs, the volume level is fine
- stop and start playback of podcast, the problem persists.
- unplug and continue playback on Focus' speaker, the volume level is just fine
- unplug and plug it back in and the problem goes away.
- never have this problem when playing back over headphones (when in gym)
I have this problem only with Podcasts and don't get it at all with songs or videos.
Anyone else noticed this?
Audio output sucks on this phone, that is for sure. Major issues. Sorry to hear about yours.

how so? i'm not having any problems at all.
Did any of you notice it's not your standard 35mm jack? The headphones that come with the phone are clearly deeper than the standard jack, and have two bands around it instead of the normal one.
I presume you are using standard cable to connect to car's aux jack....
I would check to see if there is a special samsung accessory to make the proprietary jack into a standard aux output?
Samsung are notorious for using this style of jack on their phones. The Galaxy line of android phones use the same jack.

that is weird. i hook mine up to my car with the same jack i used for my iphone with no problems. in fact i am under the assumption the sound quality is actually better than with the iphone.
maybe this is a canada thing?
The plug is set up to use headsets with the microphone, and may not work well with some older stereo audio cables. However, I have used it with a podcast and found it to work quite well. I suggest trying another cable, cuz the Focus works fine.
The line level output of the 3.5mm jack is approx. 40% less than that of the iphone, or my HTC Tilt2. That is the issue I have and that others have commented on.
For instance, iphone plugged in playing on my car stereo, Panteras Cemetary Gates @ 320kbps MP3 is mind boggling loud at 50% volume on the car and 100% volume on the iphone. With the Focus the car stereo volume needs to be at 90% to be equal to the volume of the iphone.
Also, since the Focus needs to be at 100% and the car stereo nearly 100% you hear the phones whining, hissing and popping and every non-music portion.
Super lame.
There's some volume problems that I've noticed on the Focus, in that it's not consistent through playback sessions and such.
The iPhone 4 uses a Cirrus Logic codec with an integrated headphone amplifier, the Focus seems to use the built-in codec with it's headphone amplifier, which might not have the same amount of oomph.
I've measured a 7-8dB lower volume on the Focus when using a line-out cable to an Audio Precision test machine.
Thanks for reporting that! Great post.
Does anyone have this problem?
Ok, I have a mp3 car adaptor that I used with my Tilt and Tilt2 without any problems. Rich sound and bass. I plugged in my Focus (just got it last night) and music only comes out one speaker.
In my '95 M3, I run an Alpine HU (9814 IIRC) with a Line in Adaptor, I run very HD (thick) gold plated lines and a Splitter (all from Monoprice.com, one goes to my portable Sirius, other pops up by my center console sunglass cubby, split happens under the passeger seat) and I usually have my 120Gb Zune attached to it, but I tried with the Phone the other day and it worked great. Played a Tool concert and it sounded as good as the Zune. Like the Zune I set the volume to about 80%, still had plenty of head room for serious volume in the Alpine. (only way to listen to Tool is LOUD!) I do run an old school Pioneer Amp, Pioneer Kevlar Components, 2 JL Audio Stealth Boxes (each is an 8" Sub).
I want to escalate this issue but I need you guys to quickly reply on the MS forums so that it gets taken seriously. Please hit the "I need an answer too" button and give some sort of descriptive reply.

I hope that his is a software side optimization since we are able to make the volume higher with the diagnostic codes.
I added my vote there.

I have a second complaint. When I stick a headphone jack in the mic turns off, it probably is expecting an inline mic with the headphones. My problem is when I then go to pull out my headphones the phone doesn't notice and will continue to not hear. It takes two or three times reinserting and pulling out the headphones to remidy this. Is anyone else haveing this issue.

Same problem here. But is worst, I connect the Focus to my Car Auxiliary jack to use it as a mega speaker, I mean, when someone calls I can hear them, but they can not hear me. The microphone is dead when I plug it in. Someone knows a fix for this?

Can't say that I have a fix for it, but it may be the connection your cable is making with the jack in the phone. I do the same thing, have the phone mounted in a jack around the same height as my head unit and people hear me fine when I speak during a call. I am currently using a cable from radioshack designed for recessed headphone jacks. Can't think of the brand off the top of my head however.

Hi pal, thanks for the reply, but I couldn't understand very well your explanation. What is a recessed headphone jack? What is the head unit?
Thanks in advance!
I have not noticed this problem however the microphone shutting off is very annoying and funny since at&t says texting while driving is unsafe yet i have to unplug my phone while driving to turn on speaker and talk. they need to fix that ASAP

Audio Distortion Under Certain Circumstances

I use my phone as an audio player quite a bit, but I've recently noticed and issue and I was wondering if anyone else had similar problems or perhaps even overcome them. When I have my Vibrant plugged in to a power source and I plug in my headphones everything sounds fine, but if I'm plugged in to power and connect a line out cable (e.g. a male to male cable for connecting to a car stereo) I get a really nasty hiss as well as other audio artifacts. I have tried numerous combinations of different power and audio cables, headphones, and audio sinks (car stereo, home stereo, computer audio in, etc.), but the result is always consistent.
Power + AUX cable = bad audio
Power + Headphones = Good audio
AUX Cable - Power = Good Audio
Has anyone else seen/solved this with their phones?
I assume you are talking about car charger and aux out and the noise that increases as your speed increases. If that's what you are talking about I get it to. Something needs to be grounded. Exactly what I don't know. I would ask a car audio person. If I'm not mistaken all radio components ie. radio amp are grounded that's why you don't hear it. Let me make this clear nothing is broken. More like this configuration was not planned for. I'm thinking the cig lighter is not grounded by car maker. Hope this helped.
In the car audio world I seem to recall some issues with Pioneer units when an owner somehow accidentally made a bad connection. It seems that a tiny fusible link in the unit would blow, and a ground loop noise would get introduced into the system. The fix was to ground the RCA cable inputs to the stereo chassis.
Not a viable solution in this case. I also recognize this may have little direct bearing on the problem, but wonder if somehow a poor power/audio connector in the unit is/has caused the same sort of problem to rear it's ugly head.
Step 1 I think - Do you have another Aux cable to test that as a poor ground on it may have developed from just bending and twisting in normal use.
Go to radio shack and pick up a ground loop isolator. That will get rid of the feedback noise.

I also have the same sound in my car. I remember way back when I thought I was a cool kid and rocked the big subwoofers in my trunk I had the same noise. Then I learned that you couldn't have the power cable running up to the battery and rca cables going to the head unit next to each other. You had to have them separated meaning one would have to go along driver side n the other along passenger side. I tried that and presto no more noise. Its the interference of electricity generated from the alternator. Hence, Faster the engine/ alternator goes, higher the noise pitch equalling more interferance due to the higher voltage/current running thru the power cable. Sorry for all that useless info lol!! Quick fix is don't have the power cable plugged in at the same time. The sound goes away, for me at least. Hope it works for you. Other than that I wouldn't really know how to fix it with a cell phone unless that isolator thingy that the other guy said to buy would work.

You should tweet @supercurio
if anyone would know, he would
This has nothing to do with software. This is basically electrical interference in audio channel because the audio is not grounded and power plug from cigarette lighter USB is grounded. Get the isolator, they are usually less than $20, just make sure all the inputs/outputs are what's compatible with your setup.
Mine plugs into AUX port on the car, then i have a 3.5mm Y splitter, one end for phone/mp3 player the other for Sat radio.
Thanks for the tips guys; I think I'll pick up an isolator and give that a try. Unfortunately, the local Radio Shack only stocks isolators for RCA jacks, not 3.5mm, so I'll have to wait at least a few more days until it gets here.
The isolator finally showed up, and it worked perfectly. Thanks again for the advice.
Sweet, now get a flux capacitor and find a straight stretch of road. At 88 mph you'll be going at 88mph with a flux capacitor!

[Q] Aux Output on N9005 (SG Note 3)

I have tried every search term I can come up with and short of going through every post in the Q/A on the Note 3 I can't find a definitive answer on this one.
I have noticed many other devices have the same or similar problems
I am trying to use my device to play to a car radio via an Aux cable, without much luck. It has a constant humming in the background, I have tried it with a few cables and a FM Transmitter and get the same results.
No issues with headphones at all
Humming only when it is plugged into the charger, very quiet (Nearly silent) if not plugged into the charger
Tried many different combinations of cables and chargers
Is there an easy fix?
One alternative I am looking for an A2DP - FM Transmitter but it has to be USB powered as I have a 5 port charger in the car, all the ones I have seen is powered direct from the power socket. I have used A2DP direct to another car radio and it works clear as day which is why I am exploring this option, as well as the ability to skip tracks from the remote control.
I use my Sony Bluetooth handsfree for that. It works like a dream. The only issue is charging: older models can't connect to phone while charging. You should check this before you buy your BT handsfree.

Do you hear that humming when phone is plugged to charger, but engine is not running?
Does the humming change voice or get louder with higher RPM? This is pretty normal on cars that phones keep noise when playing music through AUX while charging.
So most probably your car alternator causes this. One possible way _might_ be to ground your cigarette lighter 12V(?) output from car straight to battery or/and put something between + cable that gives 12.0V to your phone charger, no more no less, since every car I have had the voltage on cigarette lighter depends on RPM. While engine off it gives what battery has (~12V) and when engine running on high RPM ~14.5V
One more way would be grounding your phone to your car, but that might be a bit hard, and I don't know would it do something bad to phone either lol
Hope this helps.
I remember a similar issue occurring a long time ago. Had to do with the screen brightness being turned down.
Does the problem also occur if you set the brightness to 100%?

Galaxy s7 Edge Major problem with headphone jack & Bluetooth

So i just got my phone on march4 and i found out 2 major problems on my s7 edge i did a research and seems to be im not the only one with this issue.
1- Bluetooth doesnt work with any wireless speaker i can connect the phone to the speaker but the music come from the phone speaker.
2- the headphone jack make static and horrible noise when you use a aux cable (for example i use my phone on my car with a aux cable and this static breaking noise is problem) now seems to be that the cord doesnt go all the way in into the headphone jack which is a huge concern to me.
3- when you are trying to listen music or audio trough the 2 option above the volume rocker only change the Ringtone volume not the Music/audio volume another big problem.
4- the stock music player is gone
A last i call samsung regardless the problem and they told me they will escalate the situation and they told to go to my carrier to order a replacement if i want to. so people remember you only have 15 days to return or get a replacement if you have the same problem.
All audio related - Sounds handset specific? Good luck on the replacement

1- i am using it in my car as bt speaker listening to pandora no prob
2- using jack for speakers at work all night pandora no static (change ur aux maybe?)
3- perfectly working for me
4- i dont see it too lol i see google play music and milk music thats it
I can't believe that these issues could be in all S7! In my opinion, it sounds like it's a faulty handset
We ordered two S7's and we are having the same noise issues with headphones. It makes a horrible noise but only when we are in the house. If you go outside, the noise stops. We have tried various things like disconnecting the wifi and nothing works. The headphones worked fine with the S5
1 is an easy fix simply user error, swipe down on the top of the screen and you should be able to select an "Audio Path/Audio Output" and from there select your speakers or headset. As for the static interference, it's hard to say what the source is from but it only occurs (at least for me) in high volume settings. Either get a shielded aux cable or use a portable amp, which is what I've been doing. If you do return it, keep us updated, I'm curious if if the static is "normal" or a defect.
Samsung's music app can be downloaded from "Galaxy Apps"
My husband and I got an s7 edge as well and we hear the same static noise when it's plugged into the aux cable. I've been thinking about taking it to my att store to see if they can help.
Static noise fix!!!
First you want to open up settings and go into sound and vibrations then you want to scroll down to swap sound quality and effects when you have an aux cable plugged in go ahead and switch the HQ upscaler from off to on and that is your solution to fixing static noises with the galaxy s7 and the galaxy S 7 edge. Everyone's welcome
I'm having the static issue as well. As soon as I touch the headphone jack (on the cord) the static is noticeable. The volume also changes.. Tried 3 different headphones, all the same.
Does this happen to anyone else?
Static issue is gone. However using the audio cable plugged into the auxiliary port in my car the audio sounds as if I'm listening through the speaker on the bottom of the phone but it's coming through the car speakers. I've tried every different setting in sounds and equalizer setting and nothing works. Looks like I may be sending 4 phones back and going with the G5
I am also having issues with the Galaxy S7, static noise from internal speaker and headphones. When you restart the phone it goes away and sounds crystal clear. I am not sure what could be causing this to randomly start, and why doesn't it happen constantly and it goes away when restarting the phone? The Samsung tech support agent said maybe an app I have on my phone is causing it. It happens with YouTube and samsung milk music, I'm not sure why only sometimes. Also it's weird that it happens in both samsung headphones and the internal phone speaker, even at low volumes.
Stock music player is not gone. Its in sam market. Taken away to make the software as bloatwarefree as possible. Blutooth through car speaker also works fine here.

Just curious if anyone has tried to use an auxiliary cable and plug it into the auxiliary port on their car stereo? How is your audio coming through?

Mine is having exactly the same issues as yours! The only way to avoid such noise is to use the BLUETOOTH speakers/headphones. What can we do now? Ask samsung to give us a new s7edge to try? Is S7e all like this?
I have a lot of static through car speakers with auxiliary cord
I've now tested 4 different headphones, 3 of them give static at the lightest touch to the headphone jack, 1 works perfectly fine.
I've never had this issue with any phone before and I have no idea what's causing it. UHQ setting doesn't make any difference.. Is it the IP68 rubber inside that's causing it?
I haven't got any of these audio issues, but allow me to list the devices I use:
BT to Mazda 6. No issues.
BT to Sony SBH-80 headphones. No issues.
BT to LG 'sound base' LAP250H. No issues.
Wired to Sennheiser sports headphones. No issues.
What I would say with aux cables, is that the quality of the cable can be the problem. If you've bought a very cheap cable off eBay then you might want to try a better quality cable - see if you're lucky enough to test one from an audio shop but DON'T let them talk you into buying some stupid £20/$20 3.5mm jack.
For bluetooth the phone will need to recognise the device as being able to play audio. There's two bluetooth outputs detected by my Mazda; I can either have the car take audio only, phone only or audio+phone. Now obviously a bluetooth speaker should default to taking audio, but I wonder if the speaker itself is at fault?

I've tried both of our Galaxy S7 Edge and S7's and different types of audio cables and with every one of them there is a problem with poor volume level where I can max the volume on both the car stereo and the phone and there's no bass. I've even taken them to Best buy and tried them on aftermarket radios and produce the same results. The samsung rep gave me the 800 number to Samsung.
I want to know if it's a hardware or software issue.

PSA: The bundled USB-C to 3.5mm adapter distorts at high volumes

The official Google adapter distorts at around the top 3-8 volume steps.
I discovered this while setting up an AUX input in my car. When stepping it down to around 7 below the maximum, the distortion goes away completely. It appears that the DAC inside the adapter is not of sufficient quality to drive 3.5mm audio at full volume.
Most users won't ever run into this because they (shouldn't be) won't be running their headphones at full volume, but it's something that's good to know. I initially thought it was a cabling / grounding issue on my AUX unit until I was able to troubleshoot it with enough trial and error to isolate where the problem was coming from.
For reference, I could run my Fire HD tablet at full volume with no distortion.
