Audio problem with the MHL adapter

I can not believe what's happening with my new cable MHL! I have a TV with DVI input, but I've never had any problem because with a simple HDMI-DVI adapter I could always play HD video on my TV and, from the headphone, I have the audio connected to a "AUX input" of a stereo. It always worked with my laptop and my hard drive media!!
The problem is that the galaxy s2 headset turns off the sound when you plug the MHL cable. I can not hear anything on my TV!
I do not know what to do, I think has no solution. I even connected the mobile audio to my notebook's bluetooth, but when I connect the mhl cable no sound is heard again!!
Does anyone have any solution? Is there any menu to force the sound through headphones?
thanks

I think I have a solution. I Expose it to help someone having the same problem:
1 .- Buy a HDMI male to 5 RCA RGB audio video av component cable
2.- Buy a DVI-I 24+5 Male to 3 RCA RGB Female Converter Adapter
Now you have the video and audio separately using an HDMI cable
3.- Connect the RGB cable to the DVI and audio cables to your stereo
*I can not put pictures of the cables because I am a new user and the system will not let me, sorry.

Sorry, HDMI doesn't carry analog audio signals. So you are out of luck with this RCA solution.
You need to a) change your TV model, or b) use a cheap AV receiver in between the GS2 and the TV set.

Think it's impossible to work? What bad news!! I don't understand why someone sells a cable that doesn't work!
What a fool I was to believe the technical characteristics of amazon:
Gold plated HDMI to 5 RCA component video audio AV cable.
Provides high resolution up to 1080p.
High definition sound and clear image transfers.
* if you write 'HDMI Male to 5 RCA RGB Audio Video AV Component Cable' in google, is one of the first result (amazon)
Does not matter, I've only lost 6 euros (ebay).
Thanks

Anyway I don't understand why we talk about converting the image and sound in analog. There are manuals about how to open an HDMI cable and also has the red, green and blue wires inside. Just for separate cables lost the concept of "digital? Not understand...
My TV has DVI input, which is also digital. As I said before, I have an HDMI female to DVI male that works perfectly on my TV when connect my laptop and my multimedia hard drive. If I could break the adapter, it would have too a derivation of wires a pin to another, right? And it works in high definition
All I wanted to do with this cable was to extract the sound from an HDMI cable because the Galaxy S2 lost the sound of the headphone and I can not connect to the AUX input of my amp.

The HDMI digital audio signal is transmitted as a single aggregated digital stream that contains a variable number of digital channels (from 2 to 7.1 and even more).
Also in the pre-HDMI days the DVD's SD multichannel digital audio stream was transferred using a single coaxial cable (electrical) or a single optical cable, hence no separated cables for every channel.
Therefore digital channels have to be previously decoded and separated, and then converted by DACs to discrete analog signals.
No hope then to directly get from HDMI a couple of stereo analog signals to feed your stereo amplifier, you should have read all the negative user reviews of that cable on Amazon UK.
My suggestion: buy a cheap (or used) AV receiver with HDMI inputs/outputs and then connect its analog stereo monitor output to the TV auxiliary audio input (red/white RCAs or 3.5mm connector), or just use a couple of speakers connected to the AV receiver.

I was really hoping to use this phone with any normal DVI monitor and use headphones connected to the phones headphone jack. I guess this destroys that idea.
Why is it that everytime something like MHL comes along they implement it with absolutely no foresight as to how it might be used?

I think that MHL is just similar to HDMI in that respect.
So you wouldn't get analog audio output from the GS2 even if it had an HDMI instead of an MHL.
Today the manufacturers of latest cell phones expect connections only with TV sets equipped with complete digital ports (generally HDMI), not considering their products to be used with computer monitors.
BTW, DVI video-only port today is considered not suitable for full-HD audio-video material, and probably couldn't even fully support 1080p/24fps video signals.

DVI monitors support 60hz 1080p okay. Whether or not they cans support 1080p/30 or 1080p/24 purely depends on the monitor's firmware. Most monitors woudn't support 24hz but some probably support 30hz, which I think the GSII uses.
Also I didn't know HDMI out on phones did the same thing. Thanks for telling me that.

I guess it's the matter of audio routing!
Maybe someday someone could mod the kernel to handle these types of situations ;-)
Fingers crossed!

I found this app "SoundAbout" witch let you change the output
it works perfectly for me, sound on the smartphone and video on the monitor (tested on galaxy s3)

Thank you Coincoin0017. But the problem resolved itself when I installed android 4.0.4. Now the headphone output works when I plug the MHL adapter

now days they only cater for the mainstream market.
the assumption was probably everyone will only use it on a hdtv that has its own speakers.
I agree its a sad state of affairs but thats how it is I guess, I am currently trying to get sound as I am using a hdmi monitor which has no speakers.

Excellent. ... (hopefully still works on 4.3) I have the same problem with my PWD8 which is a panel so doesn't have speakers.
Is it possible to take a cable from the phones (Note 2) 3.5mm jack and put it into an AV receiver so that it uses the speakers attached to it?
Or even bluetooth sound to a separate speaker from the phone?

Sound about app useful for allowing sound to get to av receiver via rca cable

Need this cable: Micro USB to 3.5mm & USB splitter

Dear awesome community,
For the past month or more I've been trying to find a place where they sell Mirco-USB to 3.5mm/USB cables, but I have come to no success whatsoever!
Is such cable impossible to make? Or am I just looking in the wrong places.
Check out the attached picture that I've created to show what I need and mean.
It looks simple, right? Now, I would love to get one of these at any price.
Help me!

Well, instead of having two wires coming out of my Note (Top and bottom) while I'm driving, a cable like this well have only one wire coming out from under the phone, cutting on clutter and annoying wires.

must be out there
heres something similar but is mini usb which is no good.

That's totally proprietary. The phone that that is made for probably doesn't even have a 3.5mm jack.

Well.. sorry to be a troll. However, you started this thread conveniently assuming that Headphone output through MicroUSB port of Note will work? Its not an HTC phone which has headset support.
May I know the reason for your ASSUMPTION that it would work even if you get the cable?

Your best bet for a single plug into your phone would probably be to use an MHL>HDMI adapter, and then get another adapter to convert from HDMI audio to 3.5mm.
That would be rather clunky though. HDMI > Anything (that isn't DVI) converters are going to run you at least about $40 for a start, and they aren't small either (probably not much smaller than the phone itself .) And they are externally-powered, so you'd need to provide power to both the MHL dongle and the HDMI converter, so it'd be super untidy.
You could do it though.
But you're probably better off using Bluetooth.

My assumption comes from the fact that there is a "docking" option in the system settings of the Galaxy Note, meaning that there is support for docking stations and probably audio output for them.
I'm not saying that the Note is the only and first phone to have it, I'm just wondering if there are such cables out there and if such thing possible to be made through Micro USB.
I had an iPhone almost 2 years ago and such cable was available easily and it did really help in my car setup, and since the Note has the same slot setup of my old iPhone I would really like to know if a cable like that is somewhere out there.

Well, looking at this car docking station...
(Link not allowed. Search for "Genuine Samsung Galaxy Note Vehicle Dock - ECS-K1E1BEGSTD" on MobileFun)
...it clearly shows a "speaker line out" socket in one of the photos, with only one connector (i.e. the micro USB connector) attaching to the phone.
So it is most certainly possible.

Hmmm, the both the official desktop dock and car dock have a 3.5mm audio out. It seems unlikely that there would be a USB DAC in the docks themselves, which suggests that analogue audio is being piped out the microUSB port on the phone itself.
Of course, the OP could just buy the official car dock to get nice tidy cabling...

If i understood the purpose of this cable, it would be:
For example:
My car supports audio input so the purpose of a cable like this would be to stream music to my car audio system and recharge de phone like a all-in-one right?

Exactly! I found out about this dock yesterday and I'm still wondering why isn't anything like of what I suggested earlier available? How come now one asked about this before!

Very Interested in this as well. OEM dock wont work with a case. So this would be a great alternative paired with a car cradle such as this.

I too really want one of these.
It is obviously possible as the destop & car dock do this.
The only way is, for someone with some electronics knowledge to pull one of these apart to see how its done. It would be interesting to see if it is straight audio out, or if there is a "Digital to Analogue Converter in there"

This might do the trick in the unlikely case that Note's microusb outputs audio. Tough I'm really interested in knowing for sure if the Galaxy Note microusb pumps line level audio.
Judging by the price of the desktop dock i wouldn't bet my money on the idea that it has not a dac. I

Output to RCA cables.. Is it possible?

I want to output my video to my dvd screen in my car. My input for the aux of the dvd player are RCA. Previously I was using a 3.5mm jack to output to RCA and this worked with my old phone (t mobile vibrant). Is there anyway to output the HDMI on this phone to rca inputs? Any help is appreciated. I posted in this thread because I'm assuming the fix would be an accessory. Thanks.

I doubt you'll find a cable to do it. hdmi is digital and the composite signal needed by the vehicle is analog. You'll need something like this:
http://www.amazon.com/HDMI-Composite-S-Video-Converter-3RCA/dp/B0047PDBP0/ref=pd_sxp_grid_i_0_0

Thanks for the quick reply, that was what I was afraid of. Guess I'm stuck with audio out for now.

I finally came up with a solution that works for me. My goal was to output the video of my phone to my dvd screen in my car. The dvd player has RCA inputs. Well rather than buying an hdmi adapter and trying to find a dc power source compatible with my car, I found an alternative solution. My old phone is a t-mobile vibrant which outputs video through a 3.5mm adapter which splits into RCA inputs. It worked fine for playing video on the screen but was outdated and I had to upgrade. The GS3 only outputs hdmi and Bluetooth is not an option for video so I had a great idea. Why not use my GS3 to wifi tether to my old Vibrant and stream audio / video through the wireless connection. So I rooted the phone, downloaded wifi tether from the play store (free) and set up my vibrant to connect to my GS3 through tether. In order to share files, I downloaded bubbleupnp (free with limitations) from the play store and now I can play files from my GS3, which wirelessly plays on my vibrant, which outputs to my RCA inputs. Its kind of a roundabout way of doing what I wanted but it works well. I can keep my vibrant in my car hooked up to a car charger, while my GS3 can be docked and charging as well. The only thing I have to do is remember to turn on my wifi tether when I get in my car and my vibrant connects automatically. And the best part is that if I play video or music from my GS3 library, I'm not downloading anything so no data usage from the wifi tether. Pretty awesome. I imagine this will work with any two DLNA devices so long as one of them has video out through rca or and older adapter. Hope this helps someone out.

And do you have two cellphones batteries to drain... have you connected 2 car chargers or anything like that? Your car panel will be with too many cables, no?

Well I do have two car chargers, One in front and one in the back. I do need to get a good mount that has power attached. I've seen the ones that plug into the lighter and they have the power built right in so that will eliminate one cable and give me a nice dock for my GS3. Not sure what I'll do with the vibrant but I won't need to access it very much so might mount it to the inside of my armrest or something. I don't think the cables will really be a problem though. I'm just happy I got it working again.

[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).

specific headset adapter needed ?

Hey guys.
I just bought the tritton kunai set for the ps3, but i want to use it to listen to music also
on the xperia play. Nicely enough the headset does have a 3.5mm jack that i can plug into the phone,
and then i found out that i need to buy a headset adapter as it is not "supported".
I'm just wondering do i need to buy a specific adapter ? and if so, could you guys link me to some.
Thanks in advance.
Also the 3.5mm jack has 3 black rings on it.

The issue is that the XPLAY, for some reason, was manufactured with a OMTP interface, which is very uncommon. Most devices use another interface called CTIA, which is the version that all other SEMC phones (to my knowledge) use, as well as iPods, BlackBerrys, WP devices, etc. use, with exception to a few old Nokias. Try finding an OMTP to CTIA or vise versa converter on amazon or ebay, as they are the same. I am not sure that the remote on the headphones will work, though, but the sound should be seamless.
