Vehicle dock charging cable.

I've just watched this video...
http://youtube/fCBFdNMhCCw
If you look at the charging cable for it, it has a 3.5mm headphone jack (so that it can be plugged into the aux in on a stereo)
Is there any way to buy just this cable so we can have audio over usb? Or even a way to hack one together DIY style?
Thanks.

Have you tried plugging usb in from the charging cable to see if you can put into mass storage mode and read files like a thumb drive? I would check that first.

That would probably work but I just have never seen a cable with the 3.5mm jack built in. I don't have my atrix yet, just doing some research into different things.
Should have it by late next week

Yeah, just so there's one cable coming down for charging and audio aux. Unfortunately, I don't see a way for a stereo or processor to read the phone properly until Harman's Google Open Protocol project gets into the market.

I have the dock/cable
One cable goes into the dock which the usb on the phone plugs into.
The HP jack comes out of the other end to connect to the AUX input in the car.
There are two labels on the cable, one says not to plug directly into the phone on the mini usb end and the other says not to plug into a PC (both in pictures)

I have the car dock and the usb cable supplied with the 3.5 mm does not work as a sync cable.

It's a dock dependent cable. Great question and perhaps abthird party will step up and manufacture a micro USB charging/ audio combo cable that can be used without seperate dock. Alternatively, contact your local rocket scientist. Lol! Actually, the multimedia dock does exactly the same thing, presenting an audio out jack.

But in the multimedia dock, I would assume that audio is coming through HDMI. This dock is much different than laptop dock and multimedia dock just because it conencts with phone only over USB but still gives an audio plug at the other end.
Also, I would assume that audio streaming is built into the cable and not in the dock because cable connecting to the dock is just a USB connector.
Now if audio is flowing through USB cable, the only question is if it can be played without using accompanied 3.5 mm audio jack?
To get to bottom of this question, it would require some USB debugging expertise which I dont have. Can anyone check with devs in forum?

There is no way audio is coming through HDMI because there is no HDMI port.
The car dock does something with the atrix where the atrix turns the USB port into analogue audio out/power. It's pretty much replacing data with audio out.
It specifically says on the cable to not plug into a computer, because the wires do not go where they are normally supposed to go (since it splits)

I have no reason to believe that the multimedia dock (not to be confused with the HD dock) and the car dock are any different in how the micro USB connector interacts with the phone. One thing that we do know is that the micro USB connector on the car dock is expecting a special cable. It literally states not to connect the car dock wire directly to the phone. Anyway, the bottom line is why does it matter, the key is that Moto engineered a product that will charge and output audio using a single connector. The car dock wire has the 3.5 mm audio out. The multimedia dock has the 3.5 mm audio out on the back... All appears to be the same to me. One thing worth noting is that the multimedia dock will not interface with a PC. I read a post that described the connection type, but can't remember what it was.

Im not sure how the he dock works, but the webtop hack has sound. If the he dock is just webtop/hd sharing, then yes, its hdmi. Charging via the usb port. But I don't own those docks, only the car dock, so im not sure.

The HDMI port is for video with audio only and used for the HD dock, lap dock and webtop hack. The micro USB port is used by the HD dock and lapdock to provide USB hub like functionality to the dock as well as a mechanism for charging the phone. This USB hub like functionality is the basis for the lapdock keyboard/track pad and HD dock wired USB keyboard and mouse. A Bluetooth keyboard/mouse can be substituted I believe, connecting via the phone's built in Bluetooth. The multimedia dock and car dock do not provide computer USB type connection capabilities, and NO video capabilites, as the HDMI connection is abscent. Instead they will charge the phone AND provide connectivity for analog audio out and that is it. The webtop hack is just a way of activating HDMIfeatures that are normally only triggered in the HD dock or lapdock.

Yes... I knew all of that... just too lazy to type that...
so... that doesn't really lead us anywhere?
I don't think you can use the vehicle dock cable with the phone directly unless someone reverse engineers the car dock.

[Q] MHL for audio, possible?

Hey all,
Not sure if this is possible but I want to somehow have audio out through the MHL/micro usb port of my s2. Reason being that it would be much nicer in the car to have 1 cord for charging and music rather than one cord for each.
Does the MHL port support this or could there possibly be an accessory to change the HDMI out feature to audio-only aux?
thanks!

also wondering about this for my AV receiver
i went ahead and ordered the HDMI MHL cable to test Spotify through my AV Receiver.

Since the HDMI audio is digital data I wouldn't bother researching down this lane.
But there certainly are docking stations that charge the SGS2 and offer a 3.5mm line-out at the same time, so it must be possible.
Pinout anyone?

Don't understand what you mean here?

If you'd like to use the HDMI audio you would have to add a digital-analog-converter in order to feed your car stereo the analog line audio it needs. Plus I don't think the connector will allow charging while in HDMI mode.
So maybe it's best to put that port on the SGS2 into Home Dock or Car Dock mode. You might get some further help wit the pinout in this thread.

I think you're getting me confused with the original poster. My question was in regards to outputting just audio (Spotify) through my Onkyo AV receiver. There shouldn't be any issue with this, right? I've only seen the MHL-HDMI cable used on a TV directly, and not through a receiver.
Also, would it be possible to plug the SGS2 with the MHL-HDMI cable directly into the HDMI 1.4 input on the back of the TV, and use the ARC feature (Audio Return Channel) to feed either 2.1 or 5.1 audio back through the HDMI cable linking the TV and receiver to the surround sound speakers?

Wait, if HDMI out audio is digital out, can we play around to get a clean digital out signal that would play nice with portable external DACs?
Sounds impossible but who knows?

That's exactly what happened, my bad.
Unfortunately I haven't got the HDMI cable for the SGS2 yet but for the ARC feature I'd say it depends on your TV. Maybe you can try feeding an existing HDMI source to it and verify that a HDMI-in on the TV can be routed via ARC to your AVR.

Yes, supposedly my TV can do that with the Freeview HD tuner audio, but I'm waiting for my antenna to put that to the test.

Solution: HD Fury II or HD Fury III. They have 2 channel analog output from HDMI input.
To clear up some things about MHL:
First of all MHL is not HDMI. By default, your phone needs to support MHL and your TV/Receiver/whatever also needs to be able to receive MHL signals.
There is no fixed connector type for MHL (the plug can either be proprietary or a readily available one such as USB or HDMI). Phones have MHL hardware connected to their USB ports. Upcoming TVs will have additional MHL hardware connected to their existing HDMI inputs.
You cannot use an ordinary USB<->HDMI type MHL cable to connect your phone to any HDTV. It will not work. You need an active cable that receives a MHL signal from the USB side, internally decodes it and reencodes it as HDMI, and then outputs it via the HDMI side of the cable to any HDMI device. That's why the cables are expensive.
The good news pertaining to this thread:
The active MHL cables we've seen so far are very small and compact. Basically the only thing you need is an MHL decoder which has an audio line out. There is no need for a HDMI DAC.

I can confirm that the Samsung MHL-HDMI cable for the SGS2 outputs both video and just audio beautifully to my home theatre receiver.

MHL to VGA is an option
Please excuse the necroposting. For future people who run across this thread when searching for MHL Audio products.
I discovered these products after some searching around:
http://vgaadapter.blogspot.com.au/2012/02/ikross-mhl-micro-usb-to-vga-display-and.html
http://www.ecvv.com/product/2822782.html
I'm not sure of the quality of the audio DAC but its an option.
But so is the Samsung Desktop dock or the car dock for charging and playing music at the same time through one plug.

i can't believe, but ac adaptor charger and p2-p2 or p2-rca cable work like a charm here

MHL MicroUSB to HDMI Adapter **VIDEO INSIDE

I bought the Samsung MHL adapter through Amazon - Samsung MHL Adapter and I must say this has been of the best inexpensive purchases you buy for your Galaxy Nexus. I decided to make a quick video to show you how great it works, please enjoy!

The MHL adapter is using full hdmi cable or mini hdmi ?

thanks for the heads up. I may have to get one of these.

Thanks for the video, it is really cool.
When I had my G2x with micro HDMI out, I bought all kines of cables to plug it into the TV from the comfort of my bed, and I really only used once or twice.
Maybe in the future I'll buy it but I think it will end up in my cable's cabinet.

How does this play out with USB host mode in Android?
Do I need another adapter for host mode? Or can I use this one while I also have HDMI out?
http://www.amazon.com/Menotek-Adapt...1?s=electronics&ie=UTF8&qid=1325341220&sr=1-1
This one seems to be "certified" for the Galaxy Nexus and also has a charging port to use while doing HDMI output. Does the Samsung adapter come with this?
I'm most certainly interesred but I want more details before shelling out money, even if it's small money
Edit: Looked at the video and I see the USB port there. Still though, how does this play wtih USB host? Do I even need an adapter for that?

Using the HDMI adapter and playing games with a controller can only be done with a bluetooth controller? Is there any way I can use HDMI and a USB PS3/360 controller?
(using the PS3 wireless is not a option for me i cannot get the app and phone to work together)

to ppl with questions, i got the official samsung gs2 mhl adapter. its 11$.
http://www.ebay.com/itm/230721222527?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
works wonders. i am 4.0.2 stock.
it uses full hdmi. 1$ on ebay.
it has a charging port, but it shows plugged in as usb charger even when plugged into the wall. it only draws enough power to power keep the charge constant, that is your battery does not go down, nor does it go up. and no, you cannot connect usb host when watching in mhl mode. would have been cool, but doesnt work.
One more thing, apparently THE PHONE HAS TO BE PLUGGED IN FOR THE MHL ADAPTER TO WORK. So, unless you plug in the charger, the mhl adater wont give output.
i hope i answered all questions.

OMG I need me on of these. It's not a Amazon prime item so that mean I have to pay for shipping lol.

nice!

Wow. So emulator+wifi+bluetooth+mhl= dead phone. 500ma is not enough to keep the GN floating.
Seems like a huge oversight on Google's part or perhaps it's just a MHL limitation. I know data does not work, which is why people have to use BT. But 500ma, what a joke.
Can anyone else confirm this?

Awesome video and post, thanks!!
Does the MHL to HDMI work with Android Movies? I know on my stock Transformer TF101 HDMI out is blocked in Movies. ...worked fine for Netflix and others though.

As far as battery is concerned. Would it be possible to program the screen to turn off when viewing in HDMI and still view it on the TV? seems like this would cut battery consumption dramatically. If not you could set the screen brightness to as low as possible.

Thanks man! Gonna buy this ASAP

Battery drain seems to be corroborated here too:

What a downer.
Great minds think alike though:
http://forum.xda-developers.com/showpost.php?p=20156851&postcount=46
So it looks like the only option is to use some sort of dual charging situation where one charges the MHL adapter and the other charges the phone via pogo.
Perhaps the native HDMI doc allows AC charging? I guess we will have to wait and see.

Use speaker dock made for apple for android

Is there any thing out there change apple dock (30pin) on speaker to work on android?

Ever since i found out you can pass audio through usb and charge at the same time, I have been wanting a speaker dock. I think with some soldering skills and a pin out of each connector you could make your own.

I doubt it. I know there are 30-pin to microUSB adapters on ebay but I'm guessing they'll only charge your phone not output audio and charge simultaneously. Most docks do have aux in so you could use that to play music and the 30-pin to microUSB to charge. Less elegant, but if you already have an ipod dock and don't want to buy a new one it could possible work.

Audio Out / Charge micro USB cable

Hi there,
I'm looking at returning back to the Android scene with a nice shiny new S3 after being over on the dark side with my iPhone (I know I know!!!). However, I do love one of the things I can do with my iPhone which is listen to my music in the car via the port at the bottom by using a Y cable which splits the output into a USB plug (for charging) and a 3.5mm Jack for AUX in sound.
Does the S3 offer music output and charging via the micro USB slot at the bottom? Has anyone tried this? I've done numerous search's and keep coming up short, with the exception of a post on here that shows the amendment of an iPhone Y cable into a Micro USB version, but that was for the S2.

If your interested in a car dock the Samsung infuse dock works for a single dock connection, but of course the dock has a charger and audio lead.

Hmm, worth thinking about! It's the all in one solution I'm after, so this might work.
Any idea if Samsung are going to bring an official dock for the s3?

We are all looking but the only thing official so far was a cradle (no connections). Speculation was perhaps an inductive charging dock but?..

The microusb does support outputting audio+taking in power.
I haven't seen a cheap cable for that purpose but just made one myself in the end from an old usb cable, an audio cable and a 690K resistor.
A y-cable made for the S2 should work fine on the S3 (that is what I based my cable on)
Ebay will probably have something suitable

Thanks for that, any write up on how it's done? What's the sound quality like please?
