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.
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.

Well, I got the Samsung dock, and as much as I like the E4GT, the dock is terrible. Here's my experience:
1. There's a ton of line noise when the phone is docked but nothing is playing, just like with the Epic. I'm using the OEM charger, but that's not the problem--using the same charger, the Photon's car dock is absolutely silent. Samsung must be using some cheap electronics in this thing, and it's simply horrible. (Sorry for venting, but seriously...)
2. The software isn't nearly as seamless as the Photon's either. First, on the Photon, when you dock an app starts that essentially takes over the home button. That means you can move back and forth between the app and the home screens easily. On the Samsung, it seems like once you leave the Vlingo app to, say start a radio streaming app, you can't get back to the dock mode. At least, not without unplugging/replugging the dock connector, but that's extra wear and tear. If I'm wrong about this, please let me know.
Then, the Photon app allows for 4 custom apps to be assigned. That provides a great deal of flexibility, and again it's easy to go from one app to another and then back to dock mode.
Overall, the Samsung car dock experience is nowhere near the Photon's. Motorola really did a great job with this, and Samsung makes it look like they gave actually using the phone in the car zero thought.
What's everyone else doing to make this experience more usable? I'm still choosing between the Photon and the E4GT, and the car dock definitely is a mark in the Photon's favor.
1) Use bluetooth audio streaming for zero noise. Are you connected by the dock's audio out jack, or the GS2's headphone jack? I noticed better sound with the latter, but using BT is easier and sounds so much better.
2) Ditch Vlingo for CarHome Ultra. Extremely customizable and lots of great features, including up to 18 app shortcuts and auto-switching day/night themes. I love it.
You could make a profile in tasker that recognizes when the phone is plugged into a dock. Or you can make one for when it is rotated in landscape and plugged in. Then, you can enable an app to run, or have a list of apps that you can choose from. This is what I do with my phone and I don't even have a dock. It's awesome how much you can do with tasker!

I'd love to do that, unfortunately my car doesn't have Bluetooth audio. And I'm going from the dock's audio out to my car's AUX in. That's an idea, using the headphone jack, but I hate adding wear and tear.

Thanks again for the tip, that app rocks. In fact, it's better than the Photon's car dock app.
Now all I need to do is find some way to clean up the line noise and I'll be a happy camper.
Go to radioshack. Ask them for a ferrite core. Should be a ring of "ferrite" or iron. Make sure it's big enough to put the plug on your audio cable through. Push it through and wrap it around a few times and see if that helps. Also, running a separate hot lead and ground from your car battery to the cigarette plug you use should help. But the ferrite core should be easier/cheaper

call audio routing
Has anyone else been able to get call audio to route to the output on the dock? media audio comes out the port so I can hear that on my cars speakers but when I make a call it comes out of the phone speaker....
So, I've tried a variety of power adapters, USB cables, and audio cables, and the line noise remains. I'm going to try the ferrite core around the audio cable, but I don't think that's the issue--if you unplug the unit from power, the line noise disappears. So, I think it's just bad circuitry in the dock.
One would think that Samsung would have received complaints about this with the Epic dock (at least) and would have fixed it. Motorola managed to make a dock with excellent sound quality and zero noise, so it's certainly possible.
Otherwise, the E4GT is decent in the car with that Carhome Ultra app. Although, that doesn't really help with my decision between the E4GT and Photon, because with the Photon I could have the same dock app but also outstanding audio quality.
I can only assume the noise you are hearing is due to a Ground Loop/Hum.
It has to do with the fact that your power source is grounded to a different point than the stereo/speakers. the hum you hear is the difference in voltage's between the 2 grounds being represented as noise in the line.
for instance. I recently installed a new head unit in my truck, the unit has an AUX in and a USB port. If i plug my E4GT aux cable into the stereo and plug the USB charger into the port on the stereo - NO Noise. However, if i plug the phone to charge in another outlet (say, the cig lighter) then there is Line Noise everytime. The same principle applies when plugging your phone audio jack into any electronics.
Hope this helps shed a little light on the noize.

I hear you, except that I have two different docks that display entirely different behavior. Actually, I have two docks from the same manufacturer (Samsung, for the Epic and the Epic Touch) that have significant line noise, and one (Motorola) that does not. Note that these are all plugged into exactly the same power adapter and outlet and using the same USB and audio cables.
So, you'd need to account for the fact that the Motorola signal is perfectly clean in precisely the same circumstances while the Samsung's signal isn't.
I believe every word of it.
From what I know about Ground Loop Hum there are many weak links in the chain, and certainly some products behave better than others. The problem is still most likely the Ground.
One possibility would be that the manufacturer of the Moto Dock has included an isolator in the power supply line (or even in the audio supply line), and the manufacturer for the Sammys didnt.
My experience in this subject is with my Laptop/DJ setup making noise when plugged into audio equipment. when the power supply was plugged into the lappy, 60hz hum. Unplug it and it goes away. More than likely the problem was inside the computer or the power supply was just poorly manufactured as other models may not have the Hum. In my case i purchased a small isolater solved the problem. It may be possible to find one for a 12v car electrical system.

I actually hooked up an old RadioShack groundloop isolator to the AUX cable, and it got rid of the hum.
Something like this should work fine: http://www.amazon.com/GROUND-LOOP-I...QTRI/ref=sr_1_2?ie=UTF8&qid=1322958491&sr=8-2

Well, the salient point is that Samsung uses inferior components. It's possible to make a device that doesn't suffer from the problem, as Motorola has shown.

most times I've had line noise, be it from improper grounding or from cellular interference (namely from ground issues) the ferrite core fixed it. If it doesn't, the power isolation will. The reason the USB Ports on the head unit doesn't create line noiseis because it has isolation circuitry built in. The core is cheap. If that doesn't work, isolate power.

Okay, in the latest saga with the Samsung car dock, I noticed this morning that when I received a Bluetooth phone call, the TuneIn Radio audio I was playing didn't stop. Or, rather, it did stop once the stream buffer ran out, because I was on 3G and of course 3G data isn't available during calls.
Is this really how the Samsung dock works, that audio doesn't give way to Bluetooth calls? Or is that perhaps the CarHome Ultra app?
Still a bit frustrated with this aspect of the Epic Touch. The Photon's car dock works perfectly, including muting audio while on a Bluetooth call.
Grrr. I know, I know, if I like the Photon's car dock so much, why I don't I just stick with that phone... But seriously, Samsung, how hard is it to get this right?

I wonder if it might be the phone or the application. When listening to Sirius/XM radio without a dock, and I get a phone call, the radio keeps blasting away.
You don't stick with that phone because this one is superior in every other way. Its a minor issue. Why would you even have the aux input selected when there is no music playing? I have the noise too so I get it but ...yeah I just change the input when I don't need it.

So after seeing how disappointing the iPhone 5 is I upgraded to the One X. Im having issues when I have my phone plugged into my Aux port in my truck. Certain notes mainly snare beats and higher notes, there is some static and popping noises. I tried turning Beats off, different cable, but still nothing. Any thoughts?
I had a problem like that with an old phone. Turned out that my case was keeping the plug from going all the way in on the phone.
Check it out. Doesn't hurt to look.
Also try the phone it a pair of headphones to rule out the phone itself as the problem.

Static and other whining noises through the car audio when connected over AUX (and especially when the phone is charging) is a very common problem. There are many reasons, all of them are due to problems of your car and not the sound source (i.e Phone). It could be due to a poor ground, electromagnetic interference, noisy power input (to the phone charger) or a phenomena called ground loop. There are cheap ground loop isolators and noise filters (on Amazon and eBay) that you can use between the AUX port and Audio output of your phone to minimize these noises.
EDIT : More info on this thread.
I feel that it might be a combination of both. I got a little static with my Inspire 4G in the car, but if I switch to my SGS3, the static is way more noticeable. I really dot know what the problem might be as I've looked into it. My first thought was the 4G signal interference but I have yet to back up that claim.

Purchase a new AUX port, can be easily installed in most vehicles. Though it could be a bit expensive.
So ive got to say this phone has been pretty much awsome for the past 24 hours but I have found its first major short coming wondering if anybody else is having this issue.
SO here is what happens. I happily plugged my note 4 into the aux audio jack in my car and then I plugged it into the car charger. That is when I get this really annoying electrical noise through the stereo system in the car. So I was like hum that is weird my note 2 only did that if the jack was not plugged in all the way. Well when a sound on the phone plays the electrical noise goes away completely and I hear the sound or song or whatever audio is playing crystal clear. Then as soon as no sounds are playing as if the audio card in the phone is not being used its like it shuts off and lets all this electrical noise coming through the charging system of the phone. Then if say a txt comes in the electrical noise sound goes away the alert plays then after the alert plays the electrical noise comes back super annoying. Can hear the alternator in the car through the noise as well. Make me wonder if it is a software issue of some sort because the noise goes away totally whenever any program takes over the audio driver and plays something through the sound card.
Anybody else have this issue? Try it if ya have not would be interesting to hear reports on this. I do not have bluetooth in my car so could not test it. I always raise the phones volume all the way up when plugged into the aux jack so I have more preamping to the stereo.
Thanks
Haven't tried on the note 4 yet but I did have this same issue on the note 2. But it was more of a white noise. Very low almost TV static noise.

I've had this issue with multiple different phones - I don't think it is the software exactly.
The only time that would ever happen to me is if I was using my aux cable AND had my normal AC charger plugged into it (using an adapter for the car that turned the "smoking thingy" into an AC socket.) If I used an adapter for the car that just gave me a USB port to charge it through only cable it would never happen.
And this happens consistently - haven't tried with my note 4 though yet though.
Try it without your charger plugged in.

I agree without the charger plugged in there is no noise at all. But it is strange that the grounding loop problem only occurs if software is not playing any audio at all. It literally goes away when something plays audio I can hear it go silent then the audio plays then there is another 8th of a second of pure silence then the noise starts again. Or say you are listening to tune in radio or something and a notification comes up. It will pause the radio program and then you will hear the noise for a split second then a sound will play silent again then split second noise then the radio will resume playing. So between the hand off of the two audio programs playing a sound you hear the noise really weird.
I agree the AC adaptor made noise for me as well on the note 2 plugged into an inverter. But this is just my normal 12 v adapter that never had a problem with the note 2. Will be interesting to hear what more ppl say with their 12 v adapters.
My power adapter above 1 amp makes a lot of noise. Had a 2.x amp for quicker charge. Had to revert to 1.x amp charger to reduce noise.
