[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

play music in car

What's the best/optimal way to listen to music in car?
I used those tape cassette things from Griffin, they're good but they break/wear out easily.
I don;t have AUX in the car. Any suggestions?

I'm not going to help much - I have one of those cassette thingies. I have used it for many years now, and it has never broken or failed. I use it for about an hour every workday, and on long trips, some of over 9 hours.
Another way I found and used for a while (no idea where it is now) was an FM transmitter. You plug into a 3.5 mm socket, and it transmits on a selected FM signal. You then just tune your radio to that frequency. I found a bit of interference, so I went back to the cassette. That also does not require batteries or cable (except audio).
When I abandon my current 13-year-old Volvo, I may try and get a car with a BT music receptor for the stereo. More likely I'll settle for one with Aux in.

I have an Aux input and a USB input but Im playing music through the bluetooth link. Ive given my GPS away and just use my note now with the google nav.

I bought jabra cruiser (Bluetooth hands free with FM transmitter ) and I have it in my car .
Once I am in I switch it on and it pairs to my note and transmits through FM.
It is a very good and handy accessory for those who doesn't have aux in nor Bluetooth stereo systems.it even have music control buttons which work perfectly well with my note.battery life is amazing too (lasts around a week with an average of 1hour playback, it can auto switch off after a few moments of inactivity so ubwont have to worry shutting it down ecevrytime )
I can't recommend it enough bcos of its many other features...
Hope this helps

Pioneers only support pandora on ios devices. At least my unit does. You can ofcourse stream whatever you want via a2dp bluetooth connection. Regardless the app you use to reproduce audio.

Quick question to add to this, I am looking at getting a new car and chances are it will have aux-in, usb and bluetooth connections.
I know the aux-in will just plug straight into my Samsung dock, but what about the usb/bluetooth.
Will I be able to control the phone music from the stereo with these, or will the usb connection even work?
That Appradio2 looks smart, hope it comes to the UK.

Get a pioneer car stereo with aux-in. I just got their cheapest model with aux for about $70... Great sound, it has built-in 4x50watt mosfet amplifier and also line out if you want to upgrade using your own amplifier.

all new pioneer units can stream whatever music app from android as long as the device supports a2dp.
When you see the Pandora logo on pioneer devices however, it means that this pioneer device can control pandora (next, previous, radio selection etc) on iOS. that's all i meant.
Just don't expect the head unit to control your pandora app on android.

The answer is probably yes for the Bluetooth, probably no (in my limited experience) for the USB.
Bluetooth does remote control through the AVRCP profile which works with the Note. As long as your stereo does AVRCP right, the note should play along.
USB is hit and miss. Most of those systems either expect an ipod attached or a simple mass storage device.

I didn't want to play around with installing a new stereo as it was a but complicated in my car. Went with the Parrot MKI9100:
www.parrot.com/uk/products/hands-free-car-kits
It's basically it's own separate amp rigged through existing setup. Sound quality is fairly good, it does have an output if you're using a power amp.
It's got full a2dp, syncs contacts to use it's own voice recognition which is much more accurate than built in Android. Voice quality is great to hear other person, not so great for other person to hear you. Big bonus is that it also has connectors for latest gen apple devices, USB, and 3.5 audio so pretty good options. Other bonus is it's well supported with firmware updates, had 2 since I've had it which have improved device compatibility and voice quality.
Installed it myself, was pretty easy once I'd looked at the wiring diagrams.
For the price though, I would probably have bought a high end double height new stereo as they have all this built in.... however, I'm a slave to impulse buys

Yeah i was a bit confused how it would recognise all the music in the 32gb of data on the phone over usb.
Probably won't bother me in the end, will normally have it in the dock to control it on long journeys anyway. As long as the music plays through usb I don't care.
If I plug it in USB how will the phone know to send the music via that rather than its own speakers like it would do with the aux-in??

If you play through Aux out:
Galaxy note reads a file on your SD (or internal memory) and the CPU feeds it to your audio chip that converts the digital file into analog voltages that go out your headphone jack and into your stereo. The quality is limited by the encoding of the file and the quality of the Note's audio chip.
If you play through A2DP:
Same as above but the CPU feeds the file to your bluetooth chip. The quality is limited by the bit rate and encoding of the A2dP protocol.
If you connect via USB to your stereo:
Your card (or internal memory) is read by the stereo, not the note. The stereo converts the file into audio output. Quality is limited by the file encoding and the quality of the stereo's sound chip (which is probably better than the note).
Make sense?

Sounds good to me. I just hope that the usb cable works with my car dock (official samsung one)
Ideally I would be able to stick a usb cable from the dock to the car and it would charge and play music, instead of me having the usb port taken up by the charger and having to use the aux-in port.
If that makes sense...

Probably will work and I am interested in your results. One minor issue is that your stereo probably will only supply a small charging current to the phone so it won't charge as fast.
You might have to put your phone in mass storage mode but maybe not. Let us know if it works.

My note does not play music via bluetooth. Car is opel insignia if it matters... Any ideas how to connect? Accept of course to turn the car is on .

I have been using a Jabra Cruiser2 with all of my cellular phones and highly recommend it. The sound quality over bluetooth+FM is, somehow, is better than what I get when I plug the phone into my vehicle's aux input.

i just tested a2dp in my MVH-8300BT pioneer and turns out that the new pioneer units do not support BT music streaming and require a bluetooth module (sold for ~150$). Aux cable for me

Vehicle integration Tips & Tricks

The S3 is the first phone that I had serious plans to integrate into my car to use for more convenient navigation, stereo audio (via A2DP), etc. I've connected it with some success but it doesn't quite work as well as I had hoped. I didn't see another thread on the topic so I thought I'd start a thread where everyone could share their tips/tricks/best practices. Here is my setup and issues:
I have a 2009 Murano LE that has bluetooth but the BT system does not support A2DP. The purchase of the Galaxy S3 coincided with the expiration of my warranty so I installed the Neo Audio GV1 setup to add A2DP (and other features). I use the Infuse 4G car mount.
The car mount works well but one complaint I have is that there's no easy way to get back into "car mode" (the S Voice thing) if I leave the S Voice app for any reason. My current solution is to quickly pop the sliding charger but of the mount out and back in.
What apps/configurations do others out there use?

I went with a Pioneer AppRadio2. It's what I view as the current leader for an integrated solution.
It uses Bluetooth for phone calls and touch screen control. The display uses HDMI to connect to the phone.
It has downsides. Number one is that it's buggy as ****. It also only allows you to control approved apps directly through the radio.
There are some really high quality apps though.
I have an ELM327 Bluetooth adapter for my OBD2 connector on the car. On my phone I run DashCommand which the AppRadio controls directly. I have real time fuel economy as well as many other readings available to me directly on the AppRadio as well as the ability to run diagnostics and pull and clear trouble codes. All of this can be done through the radio/phone combo.

omg, i've been looking for someone who has this phone with appradio 2. i absolutely hate the appradio 2. The bluetooth OBD2 seems interesting with dash command. There seems to be 2 kinds on ebay, the 1.5v and 2v?
I'm trying the infuse 4G car dock but the audio doesn't come out of the micro usb port for audio. it will only connect if I use the MHL connector directly. i'm also worried if I use CM10 it wont' be compatible with the appradio 2 anymore?

The reason the Infuse dock won't work for you is that Samsung changed the pinout on the S3 for MHL. It's now an 11-pin connector instead of 5.
For the OBD2 I got the v1.4b Elm adapter as Elm says that there is no newer version that they've created. It works really well.
I haven't tried CM10 because I'm certain that it doesn't support MHL. CM9 didn't support it on my Skyrocket either. It's a shame really, because CM9 fixed all of the Bluetooth bugs that the Touchwiz version of ICS seems to have.

Make sure it is checked for audio through the Infuse dock.

yeah I switched it and still doesn't work. I'm guessing it's not using all the pins on the Dock that the MHL uses.
Headunit > MHL > s3 works
Headunit > MHL > 4G infuse car dock > phone /w enabled dock speaker setting or not, doesn't work
this is now just a "holder" for my phone. I guess what people meant when they said it worked on the phone is that without MHL and the 3.5mm audio jack works. Apparently I need lower end equipment for this to be compatible.

I had the same experience when I tested last night, but I wasn't sure if the issue was with the Neo system where the USB is connected or not. I'm guessing based on your feedback that the dock is the issue.

sublimejosh - just to be clear, when you mentioned the Infuse dock's USB audio out functionality you didn't specifically mention that you were using this. Are you? If so, what system/device do you have the other end of the USB cable connected to?

[Q] Who here is using a DAC & MHL? [EDIT - SOLVED - USE USB OTG INSTEAD]

I'm not an "audiophile", but I probably have more critical ears than most when it comes to quality sounds. And the GSIII isn't impressing me like I hoped it would. So I'm looking to squeeze as much out of the GSIII experience as possible, while also getting a good music experience.
So, I ditched Bluetooth and finally got USB audio when docked (thank you, CM).
But still not really impressed. Now I'd like to try these DAC things. But I have zero experience with these.
What I want is to store all my 320kbps MP3's and my FLAC's on my phone. And be able to hook my phone up to my car stereo, garage stereo and home stereo's.
One thing that concerns me is the car experience. How do you guys handle things like call audio and system sounds and GPS navigation voice?
Is it like with Bluetooth & USB audio where you hear everything without having to change inputs?
So if I plug my phone into an MHL and plug that into an HDMI to digital audio converter and plug that into a DAC and plug that into my car stereo's 3.5mm or stereo RCA input, I know that I'll get great/better music (right?!?).
But will I also get call audio and system sounds and navigation voice through that same DAC input to the car stereo? Or will I have to change an input for this to happen?
edit: Forgot to mention that I have no interest in video output at all. All I want is to get digital audio out of my phone! And I'm running a CyanogenMOD hybrid ROM.
edit #2: Oh snap, what is this USB OTG thing? Looks like something I need to research. Could be a way of getting digital audio out of phone without messing with some of the other crap.
http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/270#post_8660606
EDIT #3: Yep, looks like a USB-OTG is all I need to connect my phone to a DAC. See attached pic.
Now just need to research and figure out if there is a way to charge the phone at the same time.
Edit #4: Kk, it looks like you can plug a DAC into your phone and have the phone also charge at the same time. This thread talks about it and also points to the $6 MHL adapter that is capable of doing this:
http://rootzwiki.com/topic/30615-can-you-charge-usb-host-mode-simultaneously/page__st__60
edit #5: Found a USB OTG cable with Y-cable to charging, for sale here in the USA for just $4 more than the Chinese folks. I just ordered it.
Now to buy a DAC (found a FiiO E7 on local craigslist for $35).

[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:
http://www.amazon.com/Original-Samsung-Adapter-Converter-EPL-FU10BEBSTD/dp/B0083FYL0O/ref=sr_1_6?s=electronics&ie=UTF8&qid=1366945559&sr=1-6&keywords=samsung+5-pin+to+11-pin+mhl+adapter
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.

Wait...So are you getting video only, and no audio, or nothing at all???
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 just the 5-pin to 11-pin MHL adapter for about $12 that should allow it to work if you have the older MHL/HDMI adapter.
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:
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 one audio source/device, with 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.

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.

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

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.
