Awful sound quality to my car's AUX in.

Hi there --
I'm a recent convert to the GS3 (and Android in general) from an iPhone 4. About all the music I listen to in my car was from my iPhone, and I want to do the same with my GS3, however, the sound quality from the 3.5mm jack to the AUX in on my car's deck is absolutely awful. I have to turn the volume much higher than I ever did with my iPhone or iPod, and even then the sound quality is very poor -- there is very little punch/bass in the music.
I've been researching a possible "USB car dock cable" which would allow me to get line out audio (rather than through the regular headphone jack) through the USB port on the bottom of the phone, but it seems the only solution is to buy a dock or DIY the cable yourself, nobody seems to sell them (and I'm not really willing to DIY a cable).
Any ideas what I might be able to do to improve the audio quality? I absolutely love the phone, but this is a pretty big caveat for me.

Mine sounds great, do headphones sound ok? Maybe your aux port is effed up. If that's the case exchange it ASAP. Are you rooted? Custom rom? Stock?

Headphones sound fine from my GS3, and other devices (iPhone/iPod) sound great on the same AUX jack in my car.
I am rooted running the leaked Bell Jellybean Touchwiz ROM.

Be interested to see what replies there are to this. I have the exact same problem. I find the volume is way too quiet and if I turn up the audio on my stereo I get an awful hissing noise. I have no problems on my sensation XE, only GS3. Headphones work fine so I seriously doubt its the aux port on the phone.
I have found some info that might help as your rooted.....

I also found that first link, but it only works on the International version of the GS3, I have the AT&T i747.

I have a 07 lexus, with an older bluetooth profile that does not allow for streaming music. I found a belkin product, caraudio connect, that will create a streaming a2dp profile through my aux port. On my s3/att/ics (stock), everything worked great. I had a profile for my phone audio and another for my media audio, and could connect both at the same time. This was great as i did not have to switch to aux for phone calls.
However, i had issues with hiss, drops, static, engine noise, etc. I had used many ground loop isolators in the RCA/car audio world, but never one on a 3.5mm stereo (double pole) connection. After adding the inline isolator from my aux port to the belkin product, my engine noise disappeared! I also found that when i updated to JB (CM10/sapir), both bluetooth profiles could operate at the same time without any interference issues on each profile.
If you have any questions on my rig, let me know.
parts:
Sorry, im new so it doesn't let me post outside links.
belkin: Part # F4U037tt
Ground loop isolator: Check out amazon, PAC Ground loop isolator for 3.5 MM applications. should be about 10 bucks.

Interesting topic. I've had issues with other phones where the volume couldn't be turned all the way up, as that would cause distortion. Have you tried turning your volume down a couple notches? I use my phone plugged into my car stereo all the time with zero distortion.
Could be hardware problem?

I just got the galaxy s3. Moved over from iPhone land. But am disappointed with this issue.
When I use the aux in via headphone jack and charge at the same time I get a horrible whine cracking and popping noise. This is unusual to me as I never had this issue with any of my I phones (3g and 4). This seems like a glaring oversight on Samsung part.

Car Audio & Galaxy S3 as head unit - there is no "Winning".
Okay, so for those of us who like to use our phones as a car stereo media source, there just is no 100% "Winning" that I have been able to find.
ANALOG USB AUDIO:
Sure, both TouchWiz and some AOSP ROM's support this. But there are two issues.
1) TouchWiz sucks (IMO).
2) The sound has "low level background noise" (IMO).
3) AOSP docking does not work properly, such as the CarHomeUltra does not get to disable the "home" button like it's supposed to.
DIGITAL USB AUDIO:
Okay, TouchWiz supports it but has lots of "cd-audio type skipping sounds" from time to time. No current AOSP ROM supports it. And because the USB-OTG connector requires certain pins be used on the connector, you lose the auto-dock feature regardless of ROM.
BLUETOOTH AUDIO:
It's a crappy sound for audiophiles. It's just so down compressed, it's useless for some ears.
APT-X BLUETOOTH AUDIO:
Better quality audio, but AT&T has already warned me once that I will lose my Unlimited Data plan if I keep using Bluetooth to my car stereo. And bluetooth in general is a "quirky" working technology that irks me sometimes.
What do I want? I want to be able to use a USB-DAC on an AOSP ROM and keep the auto-dock feature.

He's a little wrong there. Apt-X is an audio codec that is installed in some high end phones, and is starting to become the standard. Currently no car stereo has the capability of using this codec, but they will probably be on the market by the end of the year. Apt-X is preferred over A2DP because it is loss-less, so the audio quality is the same as plugging your phone in with a AUX cable.
AT&T is blocking you from using the Pandora app on your head unit, because technically it is tethering. The app simply sets up an Ad-Hoc network, and uses the phones internet to stream Pandora that runs on the car stereo.
But...To answer your original question, I would suggest using the standard headset port on your phone. The DAC on the USB plug is generally software driven, and will not give you as good of sound as the standard headphone jack can. If your not satisfied with the quality, get CM10 and DSP Manager to fully customize your sound.

CZ Eddie,
I feel for you...because I am going through the same dang crap.
I am surprised you have not corresponded more with me bro. There is hardly anyone out there that seems to be on this One Handed docking quest. Even though there have been HOW MANY MILLION S3's sold...we are in an unpopular niche.
The skipping that I experience is most severe when listening to MEDIA while dialing out, during a call, and during an incoming call ringing. It is like a stuck skipping CD digital like sound. The author of SoundAbout app, is trying to help me solve this issue but he does not have the usb/otg/dac arrangement that we do. One version of his app, eliminated at least the stubborn perpetual skipping, but has a byproduct of losing the media stream after a call...which requires unplugging/replugging the usb cable.
I had such a terrific setup with my old HD2. It was a lightly modified card dock but one handed docking providing POWER and AUDIO via 2 ports, usb and headphone jack. What I am sure I will have to end up doing, is having to connect the Headphone audio out by HAND as a 2nd step. At least, I will have NO SKIPPING, and all audio including CALLS coming into my car deck without any weird bumps!
If I had chosen to go USB analogue out, I get really bad noise but only when charging. Somehow, when it's charging, I get hiss, switching sounds, clicks etc. I can almost 99% confirm it is not ground loop type issues.

1) Regarding aptX: probably, it won't be aptX Loseless that makes it to car stereos, but simply aptX. The Loseless codec looks to be targeted for professionals. But, still aptX is still many times better than the ugly old SBC codec.
2) The codec will change, not the protocol: AptX replaces SBC (not A2DP). A2DP (the transfer protocol) can use whatever codec it wants. So, whenever the car stereos are released, it will be A2DP with aptX. CSR has already released an aptX Bluetooth chipset for car stereos...someone just needs to pick it up and use it now, haha!
3) Concerning BT streaming and "tethering": not to derail this thread since you already have one about this, but I think they're bluffing hard. That representative is confused and wrong. I imagine if you pressed them to provide evidence or explain what their definition of tethering was, they would fail magnificently.
----
BT is reliable for me; I mean, it's as reliable as my WiFi when I want to use it. What quirks have you experienced?
--
For enabling docking -> hmm...what about using a NFC tag? This one enables docking modes. Or, maybe use a Tasker to detect Bluetooth connectivity?

Auxiliary cord.

IMO an audiophile would never want to use their phone as their main audio source.
And you do realize that achieving true audiophile sound quality in a daily driver is all but impossible?
If your streaming Pandora your not getting anywhere near lossless quality so why not use Bluetooth? Bluetooth audio streaming has come along way. If your standard audio file on your phone is a 320kpbs mp3, your not missing anything streaming via Bluetooth. I was once skeptical about this until I finally found a good pair of BT headphones.
I'm interested to hear more detail about your car audio setup. My setup is decent, better than most everyone else I know and IMO the only difference I can hear between Bluetooth streaming audio from my phone and the music on the sd card in my stereo is the over equalization from being equalized by the phone and again by my sound processor.

Normal Bluetooth vs. other methods has an obvious degredation on the sound for me.
Yes, Pandora sounds bad even when the "high quality" selection is checked off and I pay for the higher resolution.
But, normal Bluetooth makes Pandora sound even worse, according to my ears.

Wow. I hear a boatload of difference between Bluetooth and otherwise. But I'm 42 years old and maybe my ears are just more fine tuned than yours are.
I'm using APT-X [high definition] Bluetooth right now and it's the best compromise in sound & convenience I've found so far.
I keep meaning to write up a DIY on how I have things set up. Just haven't gotten around to it yet.
Btw, you're is "you are" and "your" is not.

I wouldn't full on call myself an audiophile (too poor to be one as student) but I love higher end sound. I personally prefer an aux cord for sound, it's a little less handy I guess but so far gives the best bang for your buck as far as sound goes.

Depends. If your charging cable is too close to the aux jack you'll get electrical feedback. Had it happen with my FM transmitter...I have one of those 1->2 12V adapters with a USB port. Whenever the USB port is used it produces quite a bit of it.

I have to agree with most of what has been said here on the S3 not being up to snuff for car audio. First I will say its my favorite phone I have ever had. Just about everything else about the phone rocks. But when it comes to car audio, I have to say its the ONE and only thing I will give props to my old iphone...using the usb direct to the radio that not only played the highest quality music, but it charged it as well at the same time with one cable and nothing else to do was kick ass. I dont get why if Ipods and Iphones can make this work so well, why cant these guys? I know most stereo makers lean heavily to the iphones and android as a whole is sorta looked over for the most part, sure it may work with android, but they have all the hardware and most things are geared towards iphones. I use either a samsung hs3000 for bluetooth audio or just give up and use the aux, but neither is as good as the iphone on usb. Even the ipod/iphone on aux is not as good as usb. So it works, but your settling for sure.
Alot of times I still will just put the ipod in the car if I really want the better music quality, but I would much rather have an all in one with my phone for music, nav and calls while driving.

Seen a few stereos with mirror link that look like they would be great for android. Almost bought a sony with it but decided against it due to having to go back to a touchwiz rom as well as I'm hoping miracast will make an appearance in some stereos in the future.

Hissing over headphones.

Hi everyone, with my headphones I'm actually having this housing sound kind of like white noise until I crank the volume to the max. For a better example any audio over headphones sounds like when you have a cassette adapter in your car and you crank your decks volume but keep the volume on your device really low.
Currently I'm running Skynote 8.2 and when I first noticed it it was stock. Then I tried the AC!D sound mod. Although I don't think it did anything but now I'm at a complete loss. I get my music through 8tracks but I also have some music on my sd card and I've noticed the hissing in YouTube videos and when I stream stuff over my network on vlc.
Attached are pictures of the headphones I have, I'll also have screen shots of the AC!D mod.
TL; DR: I hear dead people. ...

Well it's a bummer that it happens on stock and custom ROMs. You may have leftover files from other sound mods if you have used more than one. I know on some mods you have to make changes in your build prop and restart. I am completely stock and I tried two EQs both of those caused a white noise in Netflix. The stock EQ sounds pretty good in Google Music but does not seem to do anything for Netflix it does lack the white noise though.
Edit: Find a pair of headphones with a lower impedance like 8 or even 4 Ohms to see if that helps. I know you tried another set but maybe they had a higher impedance also.

Having the same issue with my Sony mdr headphones. Does yours also loose wifi when this happens?

[Q] i started to hate all my music while listening to music on bluetooth

I started to really hate all my music because of the crappy sound that is generated while I listen to music on my bluetooth sony car stereo .
It really sucks and honestly i don't know who to blame is it the phone, is the stereo is it the bluetooth sound capabilities, is the kerenel
Any how listening to bluetooth music sucks sucks big big time on my note 2.
I tried all players poweramp, neutron and all other players
I tried noozoxide, I tried awsome beats all suck
I feel the music especially the vocals get lost in the bass of the woofer, I feel as if the vocals are light and so dull and all I can hear is the annoying treble or bass, if i try to lower the bass I feel my ears are getting annoyed from the irritating sharp sound, I simply Just hate my phone now. If I lower the treble I feel all is going downhill, also playing with the equalizers just f...ks up music quality.
I owned previous phones and at least I used to enjoy listening to music over bluetooth but now I simply don't anymore with note 2.
I don't know if anyone has a magical solution for this, I know many people will blame it on the blutooth but i got myself the sony BTMEX 5100 which i thing was designed to play music over bluetooth.
I don't know if still in this age we still have to use wires to listen to music I hope bluetooth streaming audio quality will improve
I remember even back in the 80s the sound quality of music coming from car stereo cassettes was music more enjoyable than what i get now from this note 2
I really wish someone to shed some light of how to enjoy music over bluetooth

I got tired of that too. I just got an aux cable. Wires suck, but it sounds a lot better.

I'm not having any issues at all with my bluetooth car stereo, plays all my music fine, running thru 2 amps running 6x9s 6.5 inch front and 12 inch sub. I'm using stock odexed rom with a custom kernel. Have started using ViPER4Android audio mod to, mainly for use with headphones. So I'm thinking it's got something to do with your setup and not so much the phones issue.

so you say you enjoy the sound quality over bluetooth
so you say that its the phone set up, can you elaborate on that, you mean I am using not so good rom ( omega 16 ) or could be the kernel, because I am confused which is responsible to deliver good quality sound over bluetooth
I know that I bought a good car stereo
I Have a big question does the sound over bluettooth quality get affected by the kernel or the rom? Or will the sound quality over bluetooth stay the same regardless what rom I use or which kernel

If you want to troubleshoot your problem you have to return to stock IMO

Doesnt appear that anyone in the audio review thread are running i to this issue, may be a faulty unit worth getting fixed, or atleast try the audio on a store unit with your headphones and see how that goes.

I was listening on the earbuds it came with earlier and didn't notice anything when using Spotify. Just now used it with my Audio Technica ATH-M50s and still no hissing or breaking up with Spotify. Spotify and Google Music is all I use and I stream all of my music. Not sure if that makes a difference.

Why would HTC do such a thing

My handset speakers sound great but I notice that when I plug my auxiliary cord in the headphone jack of my phone to input to my car stereo - it sounds terrible, all distorted and stuff. I have the same 320kbps mp3 file on my mp3 player also on my SD card of my phone so I know the file is good. I also have a high quality aux cord so I K own it's not that either. When I play the same song from my mp3 player w/my aux cord to my car stereo rather than my phone w/my aux cord to my car stereo, it sounds great. Phone output via aux cable sounds like crap. Is this cuz of boom sound and if so, how do I shut it off?

You can shut off boomsound in settings when the aux cord is connected, I also find that visualizer increases distortions when playing certain files so try not to have the music player on visualizer when playing through the headphone jack.
