[Q] Why doesn't the standard dock have HDMI out?

I just received notification that my pre-ordered speaker dock has been shipped out. Hopefully I'll get it tomorrow to play with on the weekend.
I plan to put the speaker dock in the kitchen to use as a clock radio-esque type device (with the ability to do other fun Xoom stuff).
After reading a little bit more about the speaker dock I noticed that it has an HDMI out port. Form the picture on the Moto website it looks like a standard HDMI port and not the mini one that's one the actual xoom.
What I'm curious about though is whether the standard dock also has this port. I'm OK shelling out another $50 for another dock I can put near my TV. I don't quite understand why only the speaker version would have one (but I guess if you want to connect it to a monitor with HDMI in) but connecting it to the TV/Receiver you typically already have a better sound system so having HDMI out on the standard dock at least makes sense.
tldr; Does the Xoom speaker dock come with a standard sized HDMI out port? Does anyone know if the Xoom standard dock comes with an HDMI out port?

The HD speaker dock has a micro HDMI on the back. Its the same connection that the xoom itself has. The regular charging dock does not have a HDMI plug at all. The stupid part is that the sound is routes through HDMI when plugged into a monitor or TV. I have a monitor without built in speakers so no sound plays when I plug it in. I have to plug a 3.5mm headphone adapter into my speakers to get sound.

Motorola said that there is no sound through HDMI on the xoom, but only on the speaker dock.
Sad seeing them do a last second money grab on their product

There is. I connected my Xoom to my monitor, and all the sound went through my monitors speakers.

interesting, I must of been misinformed.
Well that's a plus, can't wait for my micro hdmi to come in

That's how HDMI works, it transfers HD video and sound on the one cable.

How much does an HDMI cable cost?

Depends on a lot of things, where you buy, how long, etc.
If you go to your local Best Buy you will spend $30+ for a short cable.
I have purchased them from monoprice.com for $7 for a 15' cable. Works great.

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.

Dock with hdmi and usb/otg port?

I've been searching for a dock with both hdmi & usb/otg port on it. I wan't one so I can fast plug it into my television and use wireless keyboard at the same time.
Problem is that I can't find one with both, doesn't this exist?

I havent seen one pre-built this way...but if you find the Moto dock there should be a way to solder this in without schematics.
Best of luck.

The dock you are looking for does not exist. You can (somewhat easily) mod the HD Speaker Dock to do this, but then the speakers probably won't work (since they use the USB port for audio). Just get a Bluetooth keyboard, problem solved.

Try this, I might buy it myself.

Looks neat, but no HDMI, and how the Hell would you charge a second Xoom battery? They aren't removable (without a torx screwdriver anyway)...

Desk dock for debugging?

I was disappointed to find the Samsung dock doesn't offer USB connection.
Anyway does anyone know of a GOOD desktop dock that I can debug adb through?

You might have a look at sinjimoru docks:http://www.sinjimoru.com
Pretty nice and simple docks, usb connected and not that expensive.

If you don't mind "disfiguring" the dock a bit, you can use a Dremel tool to grind a notch in the left side of the dock to allow access to the USB port. I did this to my dock with no problem. I was hoping to use USB OTG and charge at the same time via the pogo pins. It doesn't work, since the two functions are mutually exclusive with the stock ROM, at least.

You didn't specify GSM or LTE, but I have two of these docks and they work great: http://www.amazon.com/RND-Power-Sol...5K9C/ref=sr_1_1?ie=UTF8&qid=1337015416&sr=8-1

Hi, I would like to achieve this too, could you please give some more details about the process?

No point destroying your dock, only one of these(pogo charging/usb connection) can happen at any point of time due to hardware limitations.

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?
