[Q] Audio line-out for Galaxy Nexus

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

Galaxy Nexus to iPod accesories

I have no clue what section this question would belong in. Mods, feel free to move this if there is a better place for it.
I haven't used my iPod since getting my first android, three androids ago. I do however have an iPod dock connected to my AV receiver at home, and a dock connector wired into my car. Has anyone figured out a way to use iPod accessories with their android? Ideally I wish I had the programming knowledge to emulate the iPod and have all the controls functional but that is way beyond what I'm capable of. I was thinking of getting a female dock connector and connecting a micro usb and 3.5mm audio jack so I could both charge and output audio through it. Also, what comes out of the MHL/USB on the Galaxy? Could I get analog audio from it so I would just have one usb cable to connect to charge and listen? Thoughts?

Come on... no one?

It -may- charge w/ the dock to micro usb adapter. That's pretty much it.
You won't get audio out of it, nor data more than likely (even power is up-in-the-air) simply because the system doesn't have the software to work with the connections made available w/ that adapter.
Edit: Also, you probably should've posted this in Q&A.

It would be pretty difficult to do something like that and would probably require building a device that would sit between the iPod dock and the Android phone.
It might be possible to do something like this. As long as your dock uses analog audio instead of usb audio like my car radio uses.
goo . gl / oeCYW Remove the spaces. I'm a new member and can't post links yet.

So you are saying you think it's looking to see if an ipod is connected before it looks for the audio coming out of it? I was under the assumption it was always ready for it since I need to first manually switch to the ipod input on the stereo... hmmm...

Nice. That's exactly what I was thinking of doing.

Well that link was encouraging enough that at least someone has gotten this to work. I went ahead and ordered a female dock connector from here http://aloaudio.com/30-female-dock-connector-with-wire-board.html. At worst I'm out $14.35. I'll update the thread with what I find out.

The dock connector arrived today. I haven't messed around with the one in my car but I did test the one on my AV receiver. Things I've learned:
1) If the receiver is on, there is a steady 4.9 volts available to charge my Galaxy.
2) There is some sort of check to see if an ipod is connected before it will switch to listen for audio on the input pins. I can actually hear a click of a relay when I connect my ipod that I do not hear with the wire connected.
3) I placed the ipod in the dock to get it to switch. I then I wired a headphone cable to the audio in pins of the dock. To my surprise I could play music from my Galaxy just fine.
If I could just figure out what it is looking for to know whether or not an ipod is connected, this should work just fine.

I just want to update this thread. I finally got around to messing with this again (yes 4 months later).
I have it working perfectly for audio in my car! As long as pins 1 & 2 are shorted it switches the head unit into iPod mode and audio gets sent to the speakers. Pins 2, 3, 4 are Ground, Right, and Left audio. I would record a video of it working but the only thing I have is my GN and I can't use it to play music and record video.
I gave up on my home theater receiver. There's power there to charge it but I can't figure out how to fool it to listen for the audio.

Y not just buy the ipod to universal Bluetooth adapter? That way the phone doesn't even have to be docked? Sprint sells it

I may have to buy one of those for my Klipsch iFi speakers. I was thinking about getting the official dock from Expansys, running this audio cable to the iPod input, and adding some other stuff via NFC tag to make the setup sort of like Ford Sync in my car.

[Q]iPAQ bluetooth keyboard working with Galaxy Nexus?
Hi everybody:
I had a iPAQ BT foldable keyboard (SPP, no HID), and I wish it works on my Galaxy Nexus for daily use (when playing games, or typing with Chinese input methods).
I've tried some apps, and keyPro Demo works, but it gave me a new IME which only support English input. I wondered if anybody here give me some help. Thanks all!!

hey guys, I know this thread is a little outdated but there is another option to get audio and charging from the 30-pin apple connection. I personally haven't tried this but it looks like it could work:

I own an Audi Q5 and it can stream music from either iPod, USB or 3.5'' mm jack using a Media Link Cable. It sounds nice, but your device has be locked in the glove box!! So i decided to get this device from amazon - "http://www.amazon.com/gp/product/B0087XSV08/ref=oh_details_o01_s00_i01". It streams music to your receiver via Bluetooth. I love this solution because i almost always use Google Map for my GPS navigation.
It works great because i have a Bose Sounddock with an iPod jack too.

I'm a little late to this party but I too am looking for a solution to convert my Klipsch iFi into a Bluetooth dock so we can use our Evo LTE's on it. I have a 1st gen iPod Nano on it but 2gb of music (the 4gb one we had died) just isn't getting it done. I also want the ability to run internet radio stations and playlists and what not. I bought about the cheapest iPod Bluetooth adapter available on eBay and was disappointed that it did not work. The LED on top wouldn't even light up to indicate it was getting power. They seller sent me another one and unfortunately it also does not work. The seller assured me that he tests every single one that is sent (uh huh, I believe you) so it would appear as though this particular adapter will not work. As soon as I can get a refund I will start going up the list as far as price goes. Just wonder if you were ever able to find a solution for your iFi to save me the effort of order several different adapters until I find one that works. I don't see why this one didn't work as the iFi should work just like every other iPod dock on the market as far as how it interfaces with the iPod/adapter.

This adapter you linked to looks exactly like the adapter I got from eBay but I only paid $15.99 w/free shipping. If anyone else is interested in trying out one of these types of adapters I would check eBay first. While mine didn't work for my iFi specifically the seller has good feedback so I would imagine it works for most. My issue is probably Klipsch iFi specific. I plan to order a different version from another seller for a few bucks more and can report back my findings if it works or not as another option but I wouldn't spend $40 for what looks exactly like what I paid $16 shipped for.

Anything Comparable to AppRadio 2?

I am in the market for a new head unit since the one I have has blue tooth but only phone functions. No audio streaming. Which was fine when I had the iPhone 4s because the radio actually had a Pandora Radio App. But now that I moved on to bigger and better things, Galaxy SIII I need a better head unit. My needs are really basic. 2 pre-outs (prefer 4 volts but will manage with 2 volts) Bluetooth Audio Streaming and the capability of controlling my SIII through the unit. The only head unit I found so far that does all that is the Pioneer AppRadio 2 (SPH-DA100)
Any suggestions?

i just ordered an appradio 2 earlier this week because i couldnt find anything that i liked that would do pretty much what you want to do

Maybe check out the Parrot Asteroid...

I can't believe a high end radio like the AppRadio2 does not have a dedicated subwoofer output. You only get four channels. Front & rear or Front & sub.

AppRadio2
I just bought the AppRadio 2 last week and haven't installed it yet so I've been playing aound with it in the house.
Initial thoughts were that I was going to be able to play videos, run apps all from my phone natively. I was wrong. Out of the box AppRadio2 comes with iPod connector with usb (for charging iPod/iPhone and for upgrading firmware on unit) for Android it has a HDMI connector you have to buy your own HDMI cable, MHL/slimport adaptor.
You also have to download appradio from play store along with a handful of compatible apps. Once that's done, you can finally connect your phone to the head unit via HDMI adaptor and bluetooth.
I tested out most of the free apps and was left unimpressed. Also the response time of the head unit was laggy at times (swiping screens).
I haven't used ARLiberator yet but I have done a lot of research and that app is what will probably keep me from returning the AppRadio 2.
A couple downsides are:
-no dedicated sub preout
-preouts are 2V rather than 4V
-no USB support for USB drives (***big disappointment since I have a GNEX and N4 coming in the mail-no external storage)
-no CD/DVD
-non detachable face (I work in high theft area)
I'm pretty sure thar there will be more android/smartphone compatible headunits in 2013 but I just couldn't wait. I have a 10+ year old Alpine cd player that is all but dead.
I did come across a new Sony headunit though XAV701HD. The interface is a lot better than Appradio2's and it has DVD/CD and USBx2 support! The only thing is that it uses mirrorlink which as of now only the s3 supports.
So for now I guess I'll keep the AppRadio 2 since I got it for a good price, and see what 2013 has to offer

What you are looking for is the Alpine ICS X8..... Sadly it's not out in the US yet
Sent from my GS3

Just checked Crutchfield and it's up for pre order... no ship date yet though

You can use a High/Low Level converter and connect it to the rear speakers. That's what I did =D

[Q] Note 8.0 MHL Audio problem

So I sold my Nexus 7, for the 8.0, for the MHL capability because I have the AppRadio2 and want to output the video onto the screen and audio to the car speakers. The only problem is that it doesn't seem like the 8.0 outputs audio through the mhl cable. I've tried multiple cables multiple external displays... The works. But can't seem to get audio to an external device. I've also tried an audio output app and that didn't work either. Any information is helpful. Thanks in advance guys

Wait...So are you getting video only, and no audio, or nothing at all???
Did you check the Android settings under "Accessories" for audio output options when docked or when other accessories are attached?
BTW, are you using the ARliberator App?
First of all, I don't think that the Note 8.0 is on Pioneer's list of approved/confirmed devices for use on the AppRadio2.
Also, the MHL/HDMI adapter that is sold in Pioneer's "Android Connection Kit" is the older 5-pin micro-USB connector.
You tried it with Samsung's newer 11-pin microUSB/MHL-to-HDMI adapter that is made for the SGS3 and Note2, right??? And you are plugging in the adapter to a microUSB charger, right? It will not work without this.
Pioneer's and Samsung's adapter for the SGS2 and original Note 5.3" will not work because it is the older 5-pin microUSB/MHL connector. You can buy the Samsung 5-pin to 11-pin MHL adapter for about $10 that should allow the older MHL/HDMI adapter to work:

I don't know why you'd want to use the smaller and lower Res AppRadio2's screen over the Note 8.0's anyway?!? I guess you lose AM/FM tuner and the Backup Camera if you have one.
You can bypass the AppRadio2 and just use your Tablet to get RCA line level preouts and Digital Optical (Toslink) audio from the Note 8.0 if you use the MHL adapter with this $40 device:
http://www.amazon.com/ViewHD-Premium-Audio-Extractor-Converter/dp/B00AHS8LD8/ref=sr_1_1?ie=UTF8&qid=1366941077&sr=8-1&keywords=viewhd+hdmi+digital+audio
Oh, but I forgot to mention that you would need separate car audio amplifiers to power your speakers for this setup to work. :/
I just returned my AppRadio2 and am using my SGN2 with this adapter in my car audio system to get digital audio output sent from my Note 2 to the digital optical input of my RF 3Sixty.3 DSP, then to my amplifiers and then speakers.
I'm using my Note 2 because I wanted to use just one audio source/device, that also has cell phone capability. The AppRadio2's built-in Dialer/Phone app borked/hid my Note 2's Keypad when it forces the display into landscape mode. :/ I guess that I could have used Tasker to switch back to portrait when the dialer/phone app opened, but then it is tiny on the AppRadio2's display. The International GT-N7100 SGN2 also has a hardware FM Tuner, or I use TuneIn Radio to stream almost any AM/FM station worldwide.
My car also came with a handsfree Bluetooth setup that worked much better than the AppRadio2.
I'm also using the Samsung SGS2 SmartDock in combination with the USB JoyCon EXR plugged into the SmartDock to keep my OEM Steering Wheel Controls and add extra functions to my SWC by long-pressing the buttons, etc. You have to program the JoyCon EXR with your PC before installing it, but it works great to control your Android's audio player functions with your SWC.
If you do get it working, you'll probably want to use the "Screen Standby #root" app to turn off the Note 8.0's screen backlight without putting it to sleep so it charges up faster. You must be rooted to use this app, however.

I am using ARLiberator, and in terms of compatibility its not an issue considering I'm using the MHL and not the Pioneer "Android Kit". I think it is an issue with the device itself because I tried other cables and other displays and it just doesnt seem to be able to output audio through the MHL

So you ARE getting video out, just no audio?
Hmmm...weird. You are using the 11-pin MHL adapter though, right? The "Android Connection Kit" uses a "MHL" adapter, too, and it is actually better than the Samsung original, but it is 5-pin, and won't work with newer devices. So I just wanted to be sure you are using the 11-pin MHL adapter made for the Galaxy S3/4 and Note 2?
Also, maybe check that the audio output settings are set to "Stereo" (2 Channel), and not to "5.1 Surround"? IDK?
Have you done the new firmware updates on the Note 8.0 yet? There is a thread here about it.

This is probably a dumb question, but you have checked the volume level on the note once connected, right?
I just setup an HDMI connection on my unit and didn't get audio at first. Turns out that it doesn't send line level audio over HDMI. It creates a new mixer item that is muted by default on the note side.
Once I adjusted that, everything worked fine. Best of luck.

I couldnt figure it out, so after all was said and done, I just factory reset it, and now it works. Although it was kind of a pain, it turned out ok in the end

Bummer you had to resort to a factory reset, but glad it's working for you now! Rock on.

I'm not sure if this is a HDCP issue or a implementation issue but that's likely the way it is.
On my Galaxy S3, last time I tried it, I think you could have audio over Bluetooth or jack while doing HDMI/MHL video out. But it's been quite a while since I've had the cable. (It's perfectly fine on the SII X/Hercules as I had my fiancee try it before I got myself the wireless adapter.)
Under the Miracast (AllShare Cast) stuff, you are only able to direct audio through the dongle and thus need an adaptor that can split off the audio from the HDMI somehow, assuming those support the necessary HDCP crap.

[Q] USB Audio..

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).
I

Still no USB-OTG in kitkat

Just tried it. USB-OTG does not work on stock, unrooted 4.4. Neither flash drives nor USB Audio

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.

I bought the HifiMeDIY DAC and am using stock 4.4.2 w/ Elemental X Kernal. I don't get any sound out of the dac. What did you have to do to enable the USB sound instead of built-in speakers?

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)!
