Using for Media Player in Car = Buzzing Sound

I use the phone as my media player in the car. When I plugged it in to the AUX on the car stereo AND it is on the charger there is a buzzing and whining sound. This was almost an instant return. However it seems to be that it is only in that condition if the phone is not outputting any sound. Once I engaged GPS, or MP3s the buzzing sound goes away (not quite but actually gone). I need to test more for long pauses in between navigation prompts, but it seems to be ok as long as some app is planning to make a sound to the headphone port. Maybe a power saving feature?
I never had this with my EVO, my Wife's Epic 4G, or any other phone I have owned.

I experienced the same phenomenon on an LG g2x. Only would buzz when NOT playing sound.
EDIT: not in a car, this was on an A/C adaptor at home.

the noise you are hearing is from the alternator of your car.( the whinning) go in your car hook up your phone and charger and give it some gas, you will hear what i mean. there is nothing wrong with your car or phone, its actually something that is rather common, so dont worry. you can buy a '' 3.5mm ground loop isolator to hook up and it should take that sound away.
hope this helps

using it as a usb drive, is better than the aux input
the phone isnt grounded very well, and will cause some noise issues
and the headphone output really isnt that strong in comparison to the evo series, imo

What receiver are you using? I tried the C3, but when it was fully charged fro some reason the sound goes to crap.

Here is a video of the noise. Note the car is NOT running. All the noise you hear comes from the stereo aux and phone. When I plug in my EVO, or the wife's Epic 4G there is NONE of this.
http://youtu.be/YoqdwVlpBAQ
It really freaks when panning and zooming.

I read this post this AM and decided to do my own testing. I used a Monster Cable 3, a generic Radio Shack cable, and something I found in a parking lot for the AUX, and 3 different car chargers and 2 different ones for the AC tests. I also tested with the music app, navigation, and no apps.
The results:
no apps - popping noises no matter what combination of cables or chargers I used
Music - popping noises when not playing music no matter what combination of cables or chargers I used
Navigation - popping noises when not navigation nowmatter what combination of cables or chargers I used
It seems that if you have something generating sound the popping sounds are gone (or at least mutted to the point where I didn't hear them). Otherwise, you get all sorts of odd noises as reported by other posters.
The car chargers were a BB charger, an iGo charger, and a Motorola charger and the test was repeated with both the engine running and just in AC mode (to keep the chargers active). The AC chargers were the out of box charger and my BB rapid charger.
I also repeated the tests with my wife's Evo and my old BlackBerry tour. Nether of those phones exhibited the same issue although both picked up some minor alternator whine when I was driving.

I can't tell what truck you got splashing through the puddle in your profile, but I am driving (having this issue) in a Nissan Frontier. I too tried several cables and chargers always with the same result. I even ran power from my Motor Cycle and Audio to the Truck AUX and still had noise.
So then I tested this in my wife's car (Chrysler Sebring) and the noise is not there, gone nada. WTH?
I took advice from someone else on this thread and hooked up a Bluetooth receiver to the aux and that works fine.
My conclusion is it must be something between my Nissan Aux and this phone when connected directly.

[Q] Loud "pops" when using the Samsung vehicle dock

Hi there.
I just recently bought my SGSII, and even more recently received the Samsung vehicle dock/holder with charger and line out. It seems like a quality unit, and it sounds very well when playing music etc, but there is a huge annoyance: Every time android initializes some sound, whether it be when the music player plays the first song, the voice in the google navigation program, or a system sound, a loud "popping" sound can be heard. I tried turning all system sounds off, but it's very annoying when using the navigation program. Has anyone had this same problem?
Other than this, the output from the unit is loud and clear (no volume issues), and there is not much background noise. I considered the wiring on my 2008 VW touran, but that should be good. I also tried it on another car (Jeep with an aftermarket stereo). I have used an iPhone with a similar style dock (ie one that splits the USB/dock connector to a charger and aux) without these issues earlier.
So, has anyone else experienced the same problem, or should there be no pops? Could it be a defective unit? Otherwise, could it be due to some bug in the OS? I have the latest official build from Kies. (2.3.5, I9100XXKI4, GINGERBREAD.XWKI8).
Thanks in advance.

I have a Alpine indash monitor and when I use the USB connection and hook up my phone and mount the storage ( to play music over my stereo) it starts to play a loud popping noise till it finds all the music files on my phone. For example if I have 50 songs it pops 50 times. Really really annoying cause I I hear is popping noises before my music starts to play

So is this with the USB cable straight to the GS2 or thru the vehicle dock's USB?

Samsung Norway just got back to me after having tested their own devices, and it seems they also had the same problem. So they just told me that that's the way this thing works. Which is very strange, I can't imagine they don't get more complains. Surely, noone wants ear wrecking noise before any message from the navigation app or music player?
Are there no fellow vehicle dock users out there who can confirm if this is normal?

I'm using the desk dock and I have the same problem, never found a solution, I tried several roms and kernels

Thanks for your reply. Seems very odd, almost as if there is some firmware/software problem, something emitting an audio signal that shouldn't be there. Let me see, wasn't there a thread about making your own usb to charge/audio out here...

I received the car dock the other day and have encountered the same problem. Any time the android system "does" something other than just playing the music, terrible loud pops occur.
Between this and the fact that the call audio is not routed through the dock's 3.5" jack has me considering returning it! I wish this fact was better explained in the Samsung literature on the dock.

I also considered returning the unit, but I think it might be a software flaw. At least, it should be possible to make a software workaround (drivers/firmware) for this, as it seems to be caused by audio initialization in the phone. Is this something for the developers? Do any of you have experience with same kinds of accessories with other brands using a micro USB connector as dock?

this has got to be a bad ground. the only time i get a pop is when i place/remove the phone from my dock or plug/unplug the usb power and i blame that on a bad ground for the usb adapter in my cigarette lighter.
if it doesnt pop while off usb power than its the ground plain and simple
edit: sorry for hijacking this thread but could you post a screen shot of the car home or desk home app?

I can't imagine this being due to a bad ground. Its a 3 years old car, and i've also tested the unit in a brand new Citroen c5 with the exact same pops. In addition the Norwegian Samsung people say its the same with their units. Out of curiosity, what firmware are you running on yours? I'll see if I can arrange a screenshot.

3.5mm Headphone jack not registering...

I have a Sprint Galaxy Nexus running CNA 3.4.1. I've only used the headphone jack maybe twice before to listen to music and everything worked just as it should. Recently however, i tried plugging in some regular headphones and when i played my music it came out the speakers. So i tried a few different headphones and some speakers and still the same problem. The little headphone icon that usually shows up in the status bar doesn't show up. I looked inside the 3.5mm jack and its clean, no lint, bent wires, anything. But no matter what i do i can't seem to get any headset to work. I'm forced to use my bluetooth adapter for my speakers.
This isn't a grave issue as i may rarely use headphones at all. But knowing that option isn't there anymore is just an inconvenience.
Any help appreciated. No rush. Just wondering if anyone else ran into this problem and knows how to fix it.
Thanks in advance.
UPDATE: Turns out after trying to play music through my bluetooth adapter it doesn't work. Bluetooth is connected, my speakers are hooked up, and the music is playing on my phone. Just no sound at all. This is a big deal! It's as if my phone won't play audio through anything but the internal speaker.
Again any help is appreciated.

Return to stock ROM to see if that fixes the problems. If not, it's likely a hw issue that headphones aren't detected.

I did that and still did not recognize it. Feels like my only option left is to open the phone and see if something was disconnected or get a new one.

static noise when plugged in car

when i plug my phone into my car to play music its fine. when i use my car charger and play music at the same time tis fine but the second the music stop i hear a static noise from my speakers (which is attached to my galaxy)
this static noise is an imitation of whatever my car is doing at that moment (if im reving the engine the static will resemble the revs, same with turn signals)
anyone else experiencing this problem?

It's feedback from the car electrical system. Usually a bad alternator ground or corroded battery cables, or even the cables going to the starter.

Damn, I was hoping this wasn't a problem on the gs3. It is probably the only true thing I don't like abut my skyrocket.

I'm assuming it isn't a stock deck? Check your ground and of possible try a new location.
All in all though, Androids micro USB is a horrible horrible connection. Every Android phone I have ever owned makes some sort of hissing sound while charging and listening to audio through the headphone jack. Even the Google Nexus does. But the iphone doesn't. Go figure.

On my i747m, I could not use the USB port to listen to music while I was charging via cigarette lighter. There is a definite design flaw. I bought an Ibolt dock and am not able to use it the way it is intended. Even when I wired it myself from scratch (I'm a sound tech) it failed.
Not only does it make white noise and static between songs, but there is some kind of GATE that kicks in 1 or 2 secs after any music pause....it cuts the noise in half but it still remains...and the act of cutting, is an irritant in itself. Further more, even when your playing music, the NOISE is fighting for sonic real estate. I can hear it. I am trained.
So for me, I am running the audio out of the headphone jack. It's 98% better but still not 100%. I don't get the classic REV issue...which has to do with grounding and/or cable shielding. But, if I was you, I would go to The Source store and pick up a Ground Isolator. They have one specific for car issues like yours.

Its a ground loop.

It MIGHT... be a ground loop.
It might NOT.
Read my post #7.
If your using USB audio, there is an internal design flaw NOISE issue independent from any GROUND issues. (at least with my i747m) I can reproduce the machine like noise in the car, on a desk dock, on a separate stereo system. The Ground Loop isolator did not help my issue but it's worth trying if you get the hum/car interference noise from usb and/or headphones.

[Q] Finicky connection with car audio jack

*Edit:*
Just so those who just joined in this converstation don't get too dragged into it, I've resolved this issue simply by buying what is called a ground loop noise isolator adapter. It's main purpose is to remove the static and whining noise you hear from your speakers when you plug your phone to the car charger while connected to the speakers. But at the same time, it is keeping the signal from the aux cable of your car on "hot" so that when you plug in the phone, the phone immediately picks up the aux signal and stays connected. I basically killed two birds with one stone by getting the adapter. Here is the adapter I purchased:
http://www.amazon.com/gp/aw/d/B001EAQTRI
I will make it clear here that this aux connectivity problem has nothing to do with how cheap or expensive your aux cable is. You can use the most expensive cable or the cheapest penny cable out there and if the problem exists between your phone and your car's aux, then it won't resolve it. Either change your car's head unit (which is a stupid thing to do) or simply get the adapter. Don't return the phone over this problem, its just a dumb move. The phone is amazing. LG will have a patch for it or someone will make a ROM that tackles the problem.

Hello all,
was wondering if anyone else with the G3 (not sure if it matters, but I have the 851 variant) is having a hard time getting their phone working with the audio jack coming from their car. I drive a 2007 Scion tC and never had any problem of weird issues connecting any of my previous phones (Moto Atrix 4G, LG Nitro HD, GSIII, Nexus 5 just to name a few) to the audio jack in my car. I'll just plug it in and it connects just fine.
But for some odd reason, the G3 is having tons of issues. When I plug in the audio jack to the phone, I see the audio jack icon pop up up top next to the clock, but then some times it will just disappear on its own. Other times, it will stay there, but when I play a media, may it be music, or video from any app, the sound will play out of the speaker on the phone and not the car speakers. Unplugging it while the media is playing and replugging it again will not change anything, but if I stop the media playback, unplug it and then plug it back in, and the icon reappears and then I tap play immediately, the audio will then come out from the car speakers. Some times I have to do this multiple times to finally get it to work.
The strangest thing is, this does not happen if I plug anything else to the G3, such as a headset or an external speaker or any other devices, only in my car. It even works fine in any other car as far as I know. I've tried different audio cables in my car but it still does the same thing, so it doesn't seem to be the cable.
Is there some kind of sensor in the phone that detects connectivity of the phone to another device? I realize that when I plug in the phone to my car, the car speakers makes a couple of whining noises before it goes quiet, sort of sending or receiving a signal from the phone.
Can anybody please help me? I want to say that the phone is defective, but I can't proof so since it works just fine with any other devices. Could it be the head unit in my car is incompatible with the phone? Any advice is appreciated. Thanks!

Thanks bfranklin, I didn't realize there was another thread about it. Wish all the G3 are under the same group.

I noticed i get some crackling feedback when i hit play on a track.. but then it works fine and even with moving the aux jack it doesn't keep cracking... just on initial play/loading of the music player

I have to plug the cable in very slow or it won't work.

That was my trick initially but eventually even that didn't work. Someone mentioned to try plugging in a charger first and then plug in the aux cable and that worked. But now I bought a ground loop noise isolator and that has resolved the problem completely. I also don't get so much popping noise and no whining noise when I charge the phone while the car is running. Here's what I bought:

If you use low quality Audio cables like Monster sells it will be higher resistance than a quality cable and should register without issue. The phone struggles with discovering the connection.

I'm gonna disagree here bc I'm using a cable from a Wal-Mart discount bin, which is I'm thinking the cheapest kind available, and it doesn't work right.

I was not saying that. If you use Griffen cable at 14 . or monster cable at 20. Or rocketfish at 18. They all work the same. Just not buying that it is a cable issue. Hardware more like it. I actually just order a eBay cable for .99 cents to prove this totally wrong.

This has nothing to do with cables. I literally tried over 6 different cables and nothing worked between my phone and my car's aux port. Yet I used the same cables in my friend's car (old Nissan sentra) that has an aux port and they all worked fine with the phone. Also used a cassette aux adapter kit in my gf's sister's old SUV and it works fine with it.
This is purely hardware compatibility issue. Some head unit's aux port stays hot at all times, others don't. Some probably reacts faster than others and connects immediately so the phone doesn't drop connectivity before engaging. Again, like I've mentioned, you can either circumvent the issue by using the "charge phone first then plug in aux cable" trick, or simply buy a ground loop isolator adapter which keeps the connection hot. LG will fix the problem eventually. It was an annoyance, but a minor one, and i can't be any happier with this phone despite of the connection issue.
