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
Basically I'd like to connect my phone up to my receiver, to stream music while I workout. Would this be possible? Could I use the headphone jack, and would that be very good quality?
I was looking into a microusb to hdmi converter, but not sure that'd work yet.

Go to Radio Shack (or whatever) and get a cable that is a 3.5mm stereo plug on one end, and stereo RCA (red and white plugs) on the other.
A lot cheaper, and HDMI is going to be WAY overkill unless you are trying to play high-quality sound files stored right on the phone... Anything you're going to be streaming from Pandora or any online source will be about FM radio quality.
The cable I mentioned above is even over-qualified for most internet streaming sources.

I saw an micro usb to HDMI for $10 off monoprice, that was the only reason I was looking at that route.

That would make sense. I haven't seen them that low (of course, I haven't really looked for one either, so I guess it doesn't mean much for me to say that. )
The one disadvantage of using the USB would be that I don't think your phone would charge while plugged into the receiver.
If I remember the HDMI specs correctly, some cables are capable of delivering a charge, but very few (if any) components have the proper ports to provide a charge...yet.
Use an auxiliary to auxiliary . I use one in my truck (no bt) and my radio at work. $10 at Target.

I like the BlueBridge Bluetooth to stereo adapter:

Monoprice has a USB to hdmi with charger port for 10 bucks. Search mhl
Anyone know if I can take a 3.5mm to USB cable. Plug the 3.5mm end into my headphone jack on the phone. Then plug the USB end into the USB port on my car stereo, and listen to music that way?
I know there are other ways of listening to music, but I need the answer to this particular question for something more complicated that I'm researching.
No, can't be done.
And the only way to connect to car is with SGS3 Easy UMS.
Our phone's 3.5mm headphone jack is TRS (headphone) or TRRS (headphone and mic) only. Devices that use the 3.5mm port as a USB port specifically state that and only support charging and USB data (to put music on the device). You would need a separate device to convert the analog audio out of the 3.5mm to digital and stream it over USB and even then your car's headunit would have to support streaming digital audio over USB. Our phones do support streaming digital audio (USB audio host capability) out the micro USB cable though.
Bummer, okay thanks guys.
I think I posted in the wrong forum also. Sorry about that.
thx
thx
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.

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:

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).

Is this possible to connect my device to car usb and play audio through the car stereo. I have tried all options after connecting the USB but it just doesn't work?

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
