Hello all ,
Is there a way to get an audio line-out from the Galaxy Nexus, either using an adapter or a docking station? I'm not looking for a solution like the one offered by the Samsung Galaxy S2's car dock (which streams bluetooth audio from the phone to the dock, then the dock turns the bluetooth streaming to analog audio through a 3.5mm port) but rather something like an adapter for the MHL port or from the docking station.
Appreciate all the help!
The obvious solution (at least to me) is to plug into the headphone jack. You could also use either the media dock or MHL adapter in conjunction with an HDMI-to-analog adapter such as the one linked below:

He's asking for a line out solution because it will bypass the internal headphone amp that is utilized when the 3.5mm port is used. If you're plugging the phone into speakers or a sound system that way you'll get much better sound.
If the mhl -> HDMI cable adapter carries both audio and video, you could use an hdmi breakout adapter to split the digital audio. It depends on the HDMI output capabilities of the phone and the acceptability of digital audio for your needs.
Edit: would no doubt be a cumbersome solution. It all comes down to your usage scenario for the output.

Thank you vespoid, ardabey.
What OJ in Compton said, I'm looking to bypass the internal headphone amp, not sure if there are any details on the car dock or desk dock, I hope 3rd party manufacturers come up with something, any solutions are welcome.

Never thought about this, but a contactless dock with HDMI out directly to the AMP = audio bliss. Thanks to the forum for letting me see the obvious
Bumping this thread...has anyone successfully done this? I want line out audio for my car's 3.5mm AUX input - had it with my ipod and it sounded much better than through the headphone jack, as well the convenience of not having to maintain two volumes.
Hoping the official car dock that uses the 3 pin connector and has a 3.5 out would do this, but I'm worried it will just use BT to transmit the audio to the dock like I read the Nexus One dock did.
I wish too that the NG had line level out.
I think it's a limitation of the hardware. I think Apple is the online one that really uses line level out via it's dock connector.
I hope someday Google will use some sort of line level out on their reference hardware or built support directly into a newer OS.
I remember my old Dell DJ had line level out. Soooooo much better.
There is nothing wrong with the 3.5mm output sound quality wise.
Trying to drive headphone-like impedance (lower) with a line out isn't the best idea, but driving higher impedance inputs like your car deck isn't that bad as long as you let the amps do the "work" of boosting the volume and not your phone. While not optimal, the decrease in sound quality shouldn't be very noticeable.
The main advantage of the digital audio though USB (what apple does) IMO is that it eliminates the need to have both the USB plugged in to charge and the 3.5 mm cord for audio. It also allows song data to be shared and device control from the speaker/head unit. Good setups will recognize most android devices as mass USB storage and provide the same functionality, but I'm not sure how the MTS on the GN will affect this.
I would wait and see how the audio quality is from the dock. Even if it is bluetooth, the audio quality may not be that bad.

The problem is, that if the head unit supports MTP then yes it can read the device like mass-storage, thats fine, but it doesn't allow you to stream media from radio apps, youtube and turn-by-turn directions from gps, this is what we are looking for...
technically it's not sending analog audio output through the USB, its just reading the stored media on the phone.
I have read that samsung phones are able to accomplish sending analog audio through the USB while charging, with the correct resistance values (adapter) or possibly with software pointing the audio in that direction (for example code build into the framework/API)
this is one major thing that Android lacks over iPhone, this problem should be addressed ASAP. I'm hoping CM9 might be able to find a solution for this.
I agree, i hope they fix this soon toi. It would make the development of accessories much easier for all android phones. Seems like a no brainer but I guess Google has other priorities...

Just starred this, if the hardware is able to do that I find it completely stupid that they do not allow it.
Smartphones audio amps are not exactly famous for being top-quality so having this possibility would be great.
Thanks. The lack of this feature is ridiculous/mind-boggling/suprising.
Well, if you were waiting for the card dock to solve your problems... it doesn't. Plugging into the dock's "line out" gets you amp driven sound. I really do not understand why this is such an issue for Android. When I plug somoething into my 3 year old Nokia smartphone a window pops up for me to choose headphones, headset or line out. Why can't ICS offer the option and if in the car dock, default to line out? A USB solution is not going to help if you are using the car dock.

Which if I understand correctly uses Bluetooth to transmit compressed audio from the phone to the dock, then delivers it through the 3.5mm jack. Why not just have a digital signal go through the USB port!?

actually the pogo pin transfers the digitial audio and the dock decodes it into analog to the 3.5mm output
I bought a fiio e6 on amazon and sound quality has improved tremendously. Even with my a2dp receiver in my car, the improvement was great. Any other experience?
What kind of headphones are you using? i suspect that makes much more of a difference than the amp
I'm planning to get an E6 by the end of this month. Together with AKG K240 MK II. I will need the amp anyway, but it'll be good to know what ear-/headphones you are using.
Sent from my GT-I9100 using XDA
Just tried my E6 on my i9100. Absolutely no change at all. Tried 5 different IEM's and 2 different headphones, they all sounded the same.
Maybe your E6 is broken!
I use it with akg K317 and in my car with a beewi bba100.
I've ordered an e5, which I should receive tomorrow, from what I've read the bass boost on the e5 is better than that of the e6.
I'll report back on any change on the sound quality, although don't expect anything in-depth, I'm no audiophile
without a proper lineout from the phone, the sound will either be same or worst in most cases. Because what youre doing is amplifying an amplified signal. So, if the amplified signal from the phone is bad, i'm pretty sure your external amplifier cant fix that.
You would need the Samsung official car dock for true line-out audio. Either that or make your own cable like the one here: http://forum.xda-developers.com/showpost.php?p=20710266&postcount=14
Maybe Bluetooth audio would also work, if you have a Bluetooth receiver with a decent DAC.
No matter what you use, it will not improve the overall sound of the device as it uses a cheap and crappy sound card. Any sort of amp including the Fiio E6 only brings EQ to the music, not to mention you actually lose sound quality because your using a jack to jack method unlike the iPod where they have special cables that connects directly into the DAC of the iPod because of the special provide cables which over-passes the direct headphone jack port. (Search up Fiio L9 Cable) Also when using the jack to jack cable that's provided with the Fiio E6 it lowers the loudness of the sound when connecting via phone to the amp.
Of course then there's the human ear, if you feel like it sounds great, good for you but in reality the sound is worse with EQ added to make you think it sounds great.
If your an audiophile you have to accept that the SGS2 isn't the best music device. Cowon for example or the SGP are good sounding music players. It's a waste of money to buy a Fiio E6 Amp unless your using an iPod to be honest cause it significantly improves the iPod devices.
That's my 2 cents, take it or leave it as you wish.

Yeah, I noticed no change in sound quality with my e5. However it can make it a LOT louder, so if that's something you need, you might still want to consider getting one of these

The galaxy s 2 does also have line out which bypasses the headphone jack (for example the samsung car dock does line-out over the micro usb port) but there doesn't seem to be anything available to buy to do this without the dock. However as claimui said you can make your own cable too
Does anyone know if it is possible to get an LOD for the Epic 4G Touch?
In case you have no idea what this means, here's your lesson in audiophile gear for the day:
Line Out Dock (a.k.a. LOD), n.: a cable commonly used on audio devices which creates a "line out" similar to a headphone jack but with no volume control and often better analog signal quality. This is useful in that it allows a user to bypass the headphone jack of a device and run the audio signal straight into an external amplifier. This is often done when an audiophile-type individual has headphones which benefit from a audio source with greater output power than a portable device typically provides.
Examples of LOD's:
Apple iPod/iPhone
Sansa Fuze

Samsung HM3700 Stereo bluetooth headset
I bought the Samsung HM3700 Stereo bluetooth headset which comes with one. I am sure Monoprice.com has one or even Ebay; but if it's worth 24.99 to yah you can buy the headset.
Sort of what I'm after, but not really. I don't want a dock, I want a cable. This is for portable listening on the go with an amp.
Thanks!

That is quite interesting and just might work.
What remains to be seen is whether or not that provides superior sound quality to the headphone jack. It just occurred to me that the Samsung car dock (which I have) is essentially the same thing as that USB micro to 3.5mm jack plug unless the phone has software which can recognize the difference. In this case, volume would still be controlled via the phone. I might have to test and see if I can hear a difference in sound quality, but I doubt it (or at least doubt that the dock will be better.)
I have both the official samsung desk dock, and car dock. They both have 3.5mm audio line out. Isn't that what you're asking for? I didn't know it had a "fancy" term though..
Edit: Maybe it's not exactly what you're asking for. I think you're hoping to get line level straight out of the DAC, which I don't think is possible with the SGSII. The audio dock line out is around the same quality as the headphone jack (as far as my "non audiophile" ears can tell) and it's certainly volume-controlled by software. Anyhow, some of the new custom ROMs out have beats audio and dspmanager built-in, which go a long way into tweaking the way audio exits the device. You may want to look into that.
Yeah the desk dock is still less portable than I'm looking for. I have DSP Manager on my phone and it helps to some extent. Guess I'm just stuck with the headphone jack. Thanks!
im pretty sure you need usb-host first, i think a usb dac has been used back on the nook color w/cm7 but then you lose portability and all that.

I searched through the forums and found some posts that said in order to use your external Mic you need a Y adapter. And that it doesn't support stereo, and some other issues.
Can someone link me to a Y adapter that would work along with a good value microphone that I can use during video recording on my Galaxy S III?
I'm surprised that a company hasn't made a product for this yet where you just plug it in and it works. The camera and video quality are great, but the sound is lacking greatly.

If I find a mic with a 3.5mm jack can't I just plug it in? the ear buds that come with the phone have a microphone where the volume controls are and it picks up sound during video recording.

the headphone jack can only output a limited amount of power to drive a mic device, any non mobile mic is not going work. if you want high quality sound you must do so with the usb using either an external usb soundcard with analog 3.5mm inputs or just a usb mic like the yeti which is the best you can really get. and yes s3 has native support for almost any kind of usb device so it will work like if you plug in usbdevices to your desktop/laptop as long as it is Plug and play compatible. whether there are good apps for these usage scenarios though is another story.
oh and you are welcome...

Good info, thanks. Looked up the yeti mic you mentioned, but it's kinda pricey at $109 and not exactly portable either. Do you use it?

A few of the reviews mention it working with a couple of android phones. Only issue is it seems to pick up alot of background noise. If anyone decides to get this for their s3 please tell us how it performs.
Not really sure what you want a dedicated microphone for taking videos on a cell phone. If you are looking to make quality videos, you might as well get a decent external microphone and syncing up audio in post production. I know my brother uses this in conjunction with a 60D. Will probably sound a lot better than the $30 options posted above. http://www.amazon.com/Zoom-H1-Portable-Digital-Recorder/dp/B003QKBVYK/ref=pd_cp_MI_0
I want to record videos with decent sound quality at concerts, etc.. I don't want distorted bass and good audio picture. Recommend me ext. microphone for my SGS3, thanks!
EDIT/UPDATE January 2013: The USB-DAC option is now working for AOSP based i9300 and North American phones!

CZ Eddie said:
For the 4.1.X AOSP ROM's, only LiquidSmooth and Xylon work. If you can find them anymore. All stock based/rooted ROM's work.
LiquidSmooth ROM never skips, it had flawless audio performance. But you lose the headphone jack on LiquidSmooth. And the 4.1.X Xylon ROM was a WIP ROM with various bugs.
The 4.1.2 LiquidSmooth ROM was fantastic. Never once had any cd-skipping type sounds. Sounded excellent and was a flawless, bug-free ROM. Perfect if you didn't need the headphone jack, which was the only issue. BUT, I can't find that ROM download anymore. I have a nandroid and if someone bugged the hell out of me, I might be talked into uploading it. But it was a nandroid from a dirty flash so I can't guarantee it will work perfectly.
Stock ROM's skip sometimes when initially connecting audio and also when taking calls or other events occur. Otherwise they work great.

ORIGINAL THREAD TEXT BELOW:
---------------------------------------------------------
So, you're like me and you want to use your North American Galaxy S3 with your car stereo to stream Pandora, play MP3's and listen to your phones Navigation directions.
But, Bluetooth obviously sucks for so many reasons.
And the USB analog audio output has too many clicks/clacks and otherwise degraded sound.
So what do you do? You're an audiophile (or a wanna-be like me) and NEED better, cleaner sound!
Well, here is how you can get near audiophile quality sound from your GS3 to your car stereo.
1) Purchase an external USB DAC (digital to audio converter). This takes your phone's digital audio and cleanly converts it to analog audio for your car stereo to handle.
So why don't we just use the phone's internal DAC? Well, because it's a cheapy, crappy sounding Yamaha DAC. Samsung cheaped out on us! So we're using a BETTER DAC instead.
I bought the Behringer UCA202 USB DAC for just $30 shipped.
http://www.ebay.com/itm/160904879602?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
2) Now you need to get the digital audio out of your phone and into the external DAC! And you also need to make sure your phone still charges! So I bought this USB-OTG cable that has a charging adapter. It's just $10 shipped:
http://www.ebay.com/itm/160912100776?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
3) And then you need a dual-RCA to 3.5mm cable to get the analog audio from the DAC into the Car Stereo! I used one similar to this $3 shipped one:
http://www.ebay.com/itm/5-FT-3-5mm-...=US_Audio_Cables_Adapters&hash=item2a134140b0
And so what are the results you ask?
HOLY MOLY!
Not only is the audio quality MUCH improved, but the sound is so CLEAN now. No clicks, burps, or any other weird background noises. Just straight CD quality background silence.
Even my GPS voice sounds prettier. hahah
Bass is tighter and deeper. Highs are more revealing. Everything is so much better that a novice could tell it sounds better.
And yes, GPS navigation works perfectly. If I'm listening to Pandora or an MP3 and my GPS needs to talk, then my music will go several db quieter and GPS will speak up, then afterwards the music will automatically go back to full volume.
UPDATE EDIT: Google Maps voice gets cut off when it starts talking, if I'm not already listening to music. When music is playing, then Google Maps voice talks perfect. But if nothing else is using sound, then I think Google Maps doesn't force its voice out enough and the first part gets cut off. This could have been a one-day deal or other issue. I need more time with it.
Also, one thing I hated about Bluetooth was everytime I turned my car off for just a minute, when I would power it back on the Bluetooth would not consistently reconnect. Well, this USB-OTG has been very consistent for me so far. Music just picks back up where it left off at and is fairly quick to do so.
Cons? Well, I haven't tested hands free calling yet. But I'm told it doesn't work with this USB-OTG to DAC configuration. Maybe there is a bluetooth solution for that. I dunno? And AOSP does not yet support DACs.
UPDATE EDIT: Bluetooth hands-free works perfectly when I'm using the USB-OTG to my DAC. I'll add pics & info below.
UPDATE EDIT: Once in awhile, my cheapy DAC gets weird sounding when I first start up music. Like a CD player skipping. I just stop and start the music again and it's fine. Or it quickly goes away on it's own. Doesn't happen very often though.
UPDATE #2 EDIT:*I flashed a new ROM today and everything has been 100% flawless so far. That last ROM had lots of weird issues.
Pros? Freakin everything.
Pics are below.
Here is the DAC and the USB-OTG cable:

This is how you configure the DAC. You can probably also use the headphones output instead of the stereo RCA, but I didn't try it.
I wired up my USB-OTG cable to my iBOLT dock. It comes up through my dash defrost vents.
This is what the three connectors on the USB-OTG cable look like:
Here is the DAC being wired up. I taped up the non-used RCA's to prevent anything bugging with them.
I wrapped up the DAC with DUCT tape.
Hid it behind my dash.

The car stereo w/audio cable attached. Some car stereos have the 3.5mm connector in the back. Or a dual-RCA input. I'd prefer one of those to have a cleaner install. Maybe someday I'll upgrade my car stereo.
And here is the finished product. My S3 docked, charging and outputing beautiful digital music!

UPDATE EDIT:
Here is how you get Bluetooth hands-free calling working. I tested it today. Started listening to music via PowerAmp through the USB-OTG to DAC to my car stereo which was set to the AUX input. Then I accepted an incoming call. My car stereo automatically switched to Bluetooth input on it's own and I could hear/talk over bluetooth to the car stereo/speakers without any problem. After disconnecting the call, my car stereo automatically went back to AUX input and my USB-OTG/DAC music resumed playing nicely.
So here are the steps.
1) Connect your phone to your car stereo via Bluetooth.
2) Click the "settings" button next to your Bluetooth connection in the phone:
3) Put a checkmark in "Call Audio" and de-select "Media Audio".
4) When you accept a call on your phone, click the "headset" button and all audio will be played over your car speakers and your voice will be picked up by your hands-free microphone.
My next step is to figure out a way to get TASKER to automatically select "headset" when I'm in my car.
EDIT:
Here is my new dock and new cable solution. Just one single cable down under my dash.
Great post and very well put together but there a couple of things
1) doubt pandora is of audiophile quality
2) most people won't hear a difference since most don't have super expensive speakers in their car
3) the amp/dac you have has 2 ANALOG outputs (rca and headphone) and 1 digital output (Optical cable)....since you're using the analog output.... its been through an amp already.... then your stereo amps the signal again.... so technically you're amping an already amped signal. If you want to notice a difference use a line out/digital signal to ur stereo.
http://www.headstage.com/USB-DAC-Cable/USB-DAC-Cable-with-35mm-Mini-Plug-75cm-30::10134.html
would be the perfect solution..lineout.... small.... don't need to hide anything, and take it with you inside ur house and use it for the receiver at home also.
But if you want something with analog, lineout and portable.... i'd go with an E7 from Fiio... need to buy a 10 dollar adapter for the line out.... but for about 80 you can listen to it from ur s3 or computer straight to ur headphones via analog. use the line out adapter to hook it up to ur car stereo or home receiver. so best of both worlds.
If you're going to quote something, please don't quote a zillion pictures with it.

Absolutely it is not "audiophile" quality. But that doesn't mean it doesn't sound better with my current DAC configuration. Because it does sound better now. Though it's still limited by the lower bitrate/conversion Pandora offers us.
My 320kbps and FLAC MP3 collection sounds absolutely incredible though.

I have $60 Alpine speakers and it was a heck of a difference. I can only imagine how much better it'll get when I do eventually put high end separates in here.
My subwoofer is fairly high end though.
You don't need high end speakers to notice a cleaner sound.

3) the amp/dac you have has 2 ANALOG outputs (rca and headphone) and 1 digital output (Optical cable)....since you're using the analog output.... its been through an amp already.... then your stereo amps the signal again.... so technically you're amping an already amped signal. If you want to notice a difference use a line out/digital signal to ur stereo.

Huh?!? Nothing has been amplified before it hits my car stereo. My phone deliveres a digital signal to a converter, which convers the signal to a high end analog signal directly into my car stereo. This means neither the DAC in my phone or my car stereo is used.

Not talking about the DAC... talking about the amp section. But I read the specs wrong on your link,
"The stereo headphone output features a dedicated level control and lets you listen to both the input and output."
I thought the level control was for the headphone and RCA out, but reading more the RCA is a lineout.
The E7 you mentioned is a very popular one indeed.
This one is on my "upgrade wishlist" if I ever get more serious. It's being compared with >$300 DAC's due to the chipset it uses.
edit: removed link due to report that this particular DAC may not be compatible with Android.
Here is a list of known working DAC's:

by using the rca to headphone cable it automatically is in analog therefore not digital at all and all those conversions and amplifications can and most likely causes some signal degradation...it's kind of a round about way to get cleaner sound when your using low bitrate streaming music...

96khz/24bit...wow thats impressive.... I'm using a old silverstone DAC with a burr brown connected to an old x-head amp, But it works well since it was only 10 bucks used haha. Want to get this and find a used objective amp.

Hmm, you may want to research the subject a little more.
Subscribed.. Great thread..
Does this provide a true line out, or is volume still controlled by the phone?
Also since there's clearly audiophiles here has anyone tried or heard of this?

I have a Jetta and it would be great to be able to use my steering wheel controls to skip/replay tracks...
Again.. Great thread..

Volume is controlled by the phone still.
Though the volume button on the DAC does also affect volume.
I set mine to full volume on the DAC. Forgot to mention that in my OP.
So my Car Home Ultra application automatically sets Android volume to max, and I end up using my car stereo's volume knob for everything.

Nope, never looked into that. But there are lots of steering wheel control thingies developed for car stereos.
Something else I want to look into is this sucker. Infinity IMS:
http://www.harmanaudio.com/search_browse/product_detail.asp?urlMaterialNumber=IMS
A DAC developed *specifically* for Android should be available in January.
It's kind of expensive though.
The AudioQuest Bumblebee:
Designed specifically for Android devices
24-bit ESS Sabre conversion chip
Supports all music files including 24-bit/192kHz lossless
Drives headphones directly with 3.5mm mini-jack output
Fixed or Variable output modes
Asynchronous transfer for accurate digital timing
64-position (computer-controlled) analog volume control
Isolated dual master clocks
Colour changing LED to indicate source sample rate

I agree with killjoy. You are not getting the full benefits of your dac if it's just connected via aux in.
You will have to either use a usb or optical connection.
I was about to get a leckerton uha 6s mk ii, but I couldn't find a way to have hi fi connection with my car stereo.
And fwiw, I do connect my international sgs3 (Wolfson chip) with a denko cable interconnect tipped with neutrik plugs. Audio via neutron player. Very good. But definitely not hi fi.

So you also think that the DAC or phone is amplifying the signal? Because that's what he said.
It's a pre-amp DAC, guys.

Well that would be great if there were a plethora of car stereos with optical input, but there aren't.
This isn't an "audiophile" thread. This is a thread to help people get cleaner and better audio sound in their cars when using the S3 as a source.

Afaik all stand alone dacs have a pre amp or else you wouldn't hear music from it. However the better ones have specific connectors to bypass the internal amp to avoid double amping.
The reason I mentioned hi fi sound and the limitations of the aux in is to serve as a sort of warning to you and others. As you have the us sgs 3 (with the poor internal dac) and a cheap external, connecting via aux in is definitely a good option.
However getting a more expensive dac such as the Sabre equipped ones you mentioned MAY NOT improve your sq due to the limitations of the inter connection.

There is no freakin internal amp in this DAC. WTF.
How many times do I have to stress this point? LOL

We're not using AUX in on the DAC. We're using the digital input on the DAC. The DAC is then converting that digital signal to analog where it's being sent directly to my car stereo amps (via the car stereo).
The signal is going to be analog at some point, no matter what you have in your bag of tricks. I believe that even digital amplifiers have to convert the signal to analog at some point, though I could be wrong on that one.

That is the craziest statement ever.
Yes, interconnection will always be somewhat of a limitation.
But processing can always be improved upon.
Nice writeup, it was an a-ha moment for me recently, that I should be using my Fiio E7 in the car. Haven't done anything about it like you have.
The next step is to take the digital out of the DAC and send it right to the digital input of a DSP, such as this:
That's what I'm talking about! Who needs a head unit?

Lol I wasn't talking about the aux in of the DAC but the aux in of the stereo, which is the weak link here.
The dsp unit above is the solution your looking for if you want true hi fi. You will never get it by connecting thru aux in of stereo is what I'm saying.
Also no need for insults or derogatory statements here mate. We are all trying to help each other. My comments, whether they agree with your opinions or not, should be taken constructively

It's actually not a DAC (digital-to-analog converter). It doesn't have a Digital input, per their Website. The volume control is for monitoring the input and output so that wouldn't need a Amp. This is a USB audio interface for pc and macs.
The UCA202 allows you to connect instruments and other audio devices to your computer, effectively merging the analog and digital worlds. It accomplishes this by providing two analog mono Inputs and Outputs (for monitoring), USB connectivity and an additional S/PDIF optical output for direct analog-to-digital conversion. The stereo headphone output features a dedicated level control and lets you listen to both the input and output.
It has only analog inputs and a S/PDIF out that coverts analog to digital. So i'm sure what he's saying is that this unit takes the analog from the phone and cleans it up before it's delivered to analog input of Head Units...

I've used that specific one, just not with the digital input. I am more experienced with audio than I am with android, pm me if want to do something drastic.:thumbup:
