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

Hi, as you know SGS2 doesn't support video via 3.5mm jack like SGS does, and I was wondering if there's any way of converting HDMI to RCA?
I found this cable:
www .amazon .com/HDMI-RCA-VGA-Cable-1-8ft/dp/B002ZUI68G/ref=pd_cp_e_3
(remove spaces from the link)
but I doubt it would work as you need digital to analog conversion and the cable doesn't seem to have any "black box" that could do it.
Can anyone reccommend any (cheap) ways of connecting SGS2 to TV via RCA using phones USB port?
BTW if Samsung did it same way like they did with SGS it would make peoples lifes so much easier!!!

This is something I have tried and did not work. I bought an MHL adaptor for Samsung S2 and also HDMI to RCA cable with black box. The video and audio did not work with HDMI to RCA cable. Need help here.

From my understanding you need the micro usb mhl to scart then a scart cable going into a hdmi to composite downgrader and then you can hook up the rca cable - I haven't done this as would work out quite expensive but quite sure it would work as your problem is the hdmi to rca cable they never work as don't downgrade signal.
If anyone finds a cheaper way please let me know.
Also wondering if there is anyway to use allshare with apple tv box as I have one of these - if anyone cam help that would be great.
Apologies for highjacking thread a little bit but as a new user I'm unable to post my own thread yet!
Thanks in advance.
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.
Sent from my Atrix!
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.

Does anyone have any suggestions for a HDMI to VGA converter to use with the Xoom? Every so often I'll invite over a few people and play movies in the backyard. I've been using a laptop and projector, but after getting the Xoom I've been thinking about getting rid of that laptop.
Related question. Are there any HDMI/VGA converters that split off the audio? Should I even bother with that or just plug speakers into the headphone jack?
Kramer Electronic has 1, a VP-422
is it not possible to convert to vga without digital scalers ?
Not without a transcoder. VGA is analog, HDMI is digitial, they send a completely different kind of signal. DVI-D and HDMI are the same however (aside from the lack of audio, of course), so if your monitor or TV has DVI-D, then you can just get an adapter on eBay or monoprice for a couple bucks.
from what i've read micro hdmi doesnt have the right pins for a DVI connection.

Perhaps that's why it didn't work for me when I tried... I just ended up buying a different monitor with HDMI.
Xoom does not have the required +5V out that is needed for DVI. That's why it won't work.

Hi, im looking to buy a samsung mhl adapter however my tv only has rca connect, if i buy a hdmi to rca cable will the video still display on my tv.. i.e hdmi goes into mhl adapter and rca goes into tv... Thankyou
No, it wont work..if its just a simple adapter. Via HDMI or DVI... you get a digital signal. RCA or VGA...ect. you get a analog signal. It's not compatible to each other, except you connect a hdmi/rca converter between the two cables. Simple adapter from china just won't work..
You need a converter -- HDMI is a digital signal, whereas composite video (the single yellow RCA cable) or component video (red/green/blue RCA cables) are analog.
Something like this one from Monoprice will do the trick. eBay and Amazon also carry devices like this, in the same price range.
Thanks alot guys i will be buying a converter...
Hopefully you're aware that the video quality from composite will be quite poor.
Presumably if your TV doesn't have HDMI or VGA connectors then it's probably still a CRT screen?
Hello everyone,
I have a monitor I'd like to hook my Samsung Note 10.1 (2014) up to, but it only has a DVI-D dual link input.
I know I'll need to buy an MHL adapter, but what's the best way to go about this?
I can't find any MHL>DVI adapters, so should I pick up an MHL>HDMI adapter, then connect that to a HDMI>DVI-D dual link adapter?
Would it be able to output at the monitors native resolution (2650x1600) which is the tablet's native as well?
I've googled around for 30 minutes, can't seem to find an answer.
Any help would be much appreciated.
Thank you.
have you tried connecting other devices using HDMI>DVI-D? if it works, then it should be the same if you connect MHL>HDMI>DVI-D.
basically plug and play from MHL>HDMI, so i don't see any problem if you try MHL>HDMI>DVI-D. of course you'll lose the audio though.
HDMI and DVI-D are electrically compatible, so it should work. Source: http://en.wikipedia.org/wiki/Digital_Visual_Interface#DVI_and_HDMI_compatibility
Also, MHL (3rd gen), HDMI and DVI-D support that resolution, so I think it should work.
(source http://en.wikipedia.org/wiki/Mobile_High-Definition_Link#MHL_3.0_features)
I wonder if an unrooted tablet has the ability to route audio through the jack output when a hdmi cable is connected. If not you'll need an splitter for audio to.
