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 apologize if this is the wrong forum for this-it seemed like the best option for me. I know that it pertains to a GSIII accessory, but the problem I'm detailing could pertain to other car docks as well.
Up until recently, I've been using a tape deck adapter to connect my Android phone to my car stereo to listen to music, make calls, etc. I recently received an iBolt car dock for my phone for Christmas. It uses a microUSB connection to charge the phone and stream audio to the stereo. Normally, the audio would stream to an auxiliary plug in the stereo, but my car doesn't have such a plug.
My thinking was that I would get a 3.5mm stereo coupler to connect my tape deck adapter to the dock, and then to my phone through the microUSB connection. However, this doesn't seem to be working. With this setup, any music I play comes out of my phone's speaker, rather than the car stereo. What's odd is that when I connect my phone to the dock, I can hear the car stereo speakers pop a bit, indicating an audio connection.
I have confirmed that the coupler works properly with a different setup. (I connected my earbuds to my phone using an auxiliary cable as a bridge) Am I doing something wrong, or is this type of connection simply impossible for some reason? Any help would be greatly appreciated. I'll provide some hardware information below, if that helps.
I'm also aware that I could just keep using the tape deck adapter for sound directly, but it would be nice to eliminate that extra step in hooking my phone up.

Hi there, first of all you must make sure under "Settings - Accessory - Audio output" that this is selected when having the iBOLT Dock connected to your car 3.5 mm "cassette in" solution. It should work fine for playing music but Samsung does not transfer phone calls to an external speaker, only sounds from applications. Hope this helps?

I couldn't find the setting that you were talking about, though I found a different one that has solved the issue...sort of. I couldn't find any "accessory" menu under settings, but I did find a setting: "Settings - Advanced - Sound - Use USB Dock Audio" This lets the phone stream audio to the stereo with my convoluted little setup.
The new issue is that the sound coming out of the stereo is of terrible quality compared to simply plugging the tape deck adapter directly into the phone. I also hear a static-y, squeaky noise coming out of the speakers when nothing is playing. Is this simply due to the odd nature of the connection, or is there something I can do about it?
Hi
I'm fed up with audio quality of my HTC when connected to my Hi-Fi Amp. On headphones my HTC one sounds amazing, but when paired to my Hi-Fi amp I have to turn the audio levels on my phone and HiFi amp turned up to max just to hear the music at "normal" levels (this introduces back ground hiss / and distortion). There's an article here that explains where this is the case (in essence the output voltage from the headphone output is insufficient to drive an Hi-Fi amplifier).
Does anyone know where I can get a device (I'll call it a pre amp) that will convert (i.e. amplify) the headphone output to Line-out level voltages. I'm guessing a dock with line out would be okay - but my GF uses iPhone (with the same issues), so Ideally the headphone jack on my phone will connect to the pre-amp, with the pre-amp connecting to my Hi-Fi amplifier (the pre amp will be externally powered my mains adapter).
I live in the UK, so UK sources / experience be most relevant, but any feedback is welcomed.
Many thanks!
if you can find somewhere locally to buy/try out something like this it might work
http://www.amazon.com/Fiio-E07K-Portable-Headphone-Amplifier/dp/B00A9LHLQ6
The posts I have read show some success with certain android phones, though it's by no means a guaranteed success. It works with some Samsung devices, and our phones support USB OTG/Host mode, so at least on paper it should work.
well if the amp you're looking for is anything similar to amplifying nicer headphones, theres a couple of options available for you to just flat out buy (for anywhere from $20 - $100), or you can just make one yourself from an altoids can for $10 - $20 if you know the basics of electronics and soldering.
Supposedly you can use an OTG cable/adapter to hook up the phone to an USB DAC (must be self-powered, as the OTG cannot supply enough juice to the DAC) and then DAC to the amp. I'll try it when I get home tonight to see if it works. I read that it's possible, but haven't tried it myself.
[update] I tried hooking up my AT&T HTC One to the USB DAC (self-powered, not USB bus powered) via the OTG cable. The stock music app still play music through the phone. However, fire up PowerAmp and the music comes through the stereo! Sweet sound...
why not consider a bluetooth speaker adapter like this?

i have one, connected to my hi-fi amplifier.
it's cheap, ands sounds very good!
I am a huge fan of the HTC Bluetooth adaptor, it works great and has great sound quality for a bluetooth.
Hello guys!
I've just bought a Nexus 7 to integrate in my car dashboard. Actually I didnt had so much knowledge about it before I bought it, (I only wanted the best and I hate apple so) but I didnt thought it was junk. And that's the only thing I wanted, a non junk tablet that could play music and works as a navigator without hardware-buttons.
My old stupid Iphone 4s worked perfectly for playing and streaming sound from spotify trough a regular usb cable to my headunit, so I didnt even reflect that googles new flagship wouldnt be able to do this simple task. But it seems like it doesnt work..
I've searched for answeres but the only thing I can find is to buy a usb DAC that converts the digital audio to analog audio but then I lose the whole damn point. I want digital audio in to my headunit. And my stupid old Iphone do it great, why the **** can't google flagship do it? Feels like I have bought a extra thin rock from the stone-age.
Please tell me I'm wrong and this is possible somehow. Otherwise I gotta throw this stupid f***** sh*t tablet in the garbage as fast as ******* possibly..
Sorry for my rage.. I just feel so fooled.. I've just bought a 400$ angry birds game. :silly:
You have a couple of options:
1. Use headphone output jack from your Nexus. Hopefully your car audio headunit has an auxiliary input.
2. Bluetooth! This is what I use in my car. If your car audio headunit has bluetooth built-in, then you don't need any cables at all. Just pair your car audio to your Nexus and start playing music! If your car stereo does not have bluetooth, then you need to purchase a bluetooth car kit. These connect to an auxiliary input on your car stereo (just like #1 above). There are bluetooth kits that also stream through an FM modulator, but that should be used as a last resort as sound quality suffers materially.
I installed an Alpine bluetooth car kit and integrated it with my factory car stereo system in a 2005 Honda Accord. Since I did not get the factory CD Changer option, I had that one input open to use with the Alpine Bluetooth. I'd post a link to my YouTube video showing this, but I'm now allowed to post links yet since I'm new to this forum.
The two options listed above are the only ones I'm aware of. I'd love to hear from others if there are other options. The only drawback to both options is that you use the DAC built in the Nexus, you don't get to pass through to a better quality external DAC. The only way around that is a Slimport adapter which uses HDMI. I don't know of any car audio units that have HDMI inputs.
What you want is achievable. Nexus 7 2012 works best with Timur Kernel however Nexus 7 2013 with an AOSP build or stock with Elemental X kernel can have a USB DAC with an OTG Y cable that will simultaneously charge.
If you have Cyanogenmod you may need glitch kernel which does the same thing.
I have a HiFiMeDIY DAC and OTG Y cable (at home) but no reason I couldn't run the same thing in my car with a car charger.

I use a fiio e7 on USB and it works perfectly on cm or carbon, no extra apps or kernel required. By the way, otg works fine with Franco kernel on either Rom and hotswapping is supported. I have not yet found another rom that supports it, but I have been using just carbon for quite a while now.

Some car head decks support android USB then it would charge and do audio. Just make sure it's android compatible.
Good, then we shall fight in the shade!

Well i can tell u most of those android compatible r meant can be connect n read as a mass storage,but not as ios.
Unless someone can make a custom rom like the one for 2012 model.
Has anyone tried USB audio on 4.4 yet? I recall reading they were making some changes to USB devices (may of just been mounting drives though).

When u guys saying otg works dor aosp or some kernel ,does that mean it works with an otg y cable aswell? Like reading files from flash n keep it charge while with flash drive on?
Sorry for the thread jack op.
U and i r on the same boat,i am doing a car mount too.
I am doing a 4g lte one.
I don't have a car, I have a scooter.
Problem fixed !
So it sounds like if I have the stock rom, with the elemental X, I can do USB audio? Do I need some kind of audio manager to specify where to send the output, or would the USB dac automatically disable the on-board headphone jack?
tried PAC rom 4.3 with elemental X 1.8
no go for the DAC audio.
sound is mute no matter what i do.

The Nexus 7 is way better than you described it.
You have lots of options for car audio, and they all have downsides, but just to name a few:
Bluetooth (if your car has a bluetooth receiver)
Auxiliary input (if your car has one)
Slimport (you'd need an hdmi-audio converter, but it would sound great)
Wi-Fi direct (not very common for cars, though)

Bluetooth (if your car has a bluetooth receiver) - I need the bluethooth to connect to other things, like an odb adapter and so on. Edit: The bluethooth connection doesnt always connect automatic whit the cars headunit either so that's another problem.
Auxiliary input (if your car has one) - The aux output aint that great, not good enough for my 3500$ audio system in my car.
Slimport (you'd need an hdmi-audio converter, but it would sound great) - Yes the problem is that I need to convert the audio to analoge. It needs a converter and it still doesnt give my headunit digital audio.
Wi-Fi direct (not very common for cars, though)- I use wifi to get my cars 4g connection to the Nexus 7
So in my case. This is just a really expensive angry birds game (Without sound)!

What input options do you have on your car stereo? G7 output options are bluetooth, 3.5mm audio jack and usb-c.
Usb in cars are for charging, and some work for media files like mp3...

No, the quad dac is for the 3.5mm jack only. Apparently the only way your car can input audio is over bluetooth and presumably FM too (although there are FM transmitters the quality is average due to the low bandwith of the radiowave , it's only meant for news and music as a free service). I recomment you to buy an aftermarket car audio unit, for example Alpine makes very good units.

Cant buy an aftermarket unit since most of the car controls are access through the headunit. I thought there was a way to make the phone's hdd or external sdcard show up as usb mass storage so you can play files from there so you dont have to carry usb thumb drive all the time. Was able to do this with the older oneplus5
