dock for Samsung Captivate

I'm looking for a device that will allow us to connect our captivate to our a/v receiver so I can listen to my songs.
Thanks!

Kinda like.... 3.5mm to RCA?

This is what you're gonna want, if you're actually looking for some sort of dock like some surround sound setups come with for an Ipod I don't think you'll find anything like that.

So that 3.5mm port can only do analog output?
Thanks!

If you have a receiver that can take USB mass storage as a source, you can try using the USB cable and setting the USB mode to mass storage. Or if you have a receiver that can take bluetooth stereo audio, you can use the bluetooth. Otherwise, analog output from the 3.5mm will have to do.

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

Any non hdmi cables out there ie. rca??

Hi everyone
Is there any cables out there that either fit directly into the phone or through the dock thar output to rca or similar, as most tv's on the road or b&bs don't have a hdmi port.
Seen a mini hdmi to rca cable, but is the port on the atrix/dock a mini hdmi or some moto hybrid port.
Any info sure would make trips on the road better than STD tv rubbish.
Thanks.

I purchased an hdmi to dvi+1 connector. maybe you can get a dvi to vga than to rca and so fourth. Just trying to help. I know its a little extra but hey.

wont work without a box to convert the digital to analogue, the reson dvi-vga works on pcs is because dvi can also carry an analogue signal, but that wont help in this case

HDMI is digital, RCA is analogue. You cannot feed a digital signal into something that's analogue. You need some sort of a converter box. Too expensive of a process in my opinion.
Its easier for digital gadgets to produce HDMI signals because the signal is decoded in the device that's receiving it. Analogue signals require an output with some strength to be able to make it to the receiving end----requires more power and hardware.

correct. you could go with a MicroHDMI to HDMI, connect an HDMI to DVI+ adapter, and a headphone jack to RCA or headphone jack to headphone jack for audio, as DVI+ does not carry audio like HDMI does.
There are small portable DAC converters. they cost about $100. i have 2 for different studio equipment, but i would never use it for something like this.

What is the conector on the Atrix that outputs to hdmi ?
Thanks

I would settle for HDMI -> Fiber Optic Audio

I don't know if that is possible... cause the audio out on HDMI is only triggered most likely by video out. I have an HDMI to DVI converter, and it puts out video, but doesn't put out sound since DVI can't handle sound. The video pinout is the same. The sound plays through the phone. Which makes me think that audio only would not trigger HDMI.

Yeah, I understand what you're saying, they sell black box type of deals but would like a solution cheaper than the phone itself. Not supremely important, would just be nice.

Would love to just use hdmi but most tv in hotels/b&B's are just scart & rca. Is the output a mini hdmi or something else on the atrix, if it is I'll buy one just to try.

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.

CM9 MHL Audio Output Change

Hello. I am using CM9 on my T989.
I have an MHL adapter that is working perfectly to output video and sound to my TV.
However, I would really like to have audio be outputted from the headphone jack, which it does not do. I have connected, reconnected, looked everywhere in settings and there's no where to change the output in Android.
From what I've read some ROMs do this for some reason while others do not, which leads me to believe that there's simply a piece of code that can be edited somewhere to push audio to the headphone jack if connected instead of over HDMI. Does anyone have a clue where that code might be? Alternatively, does anyone know of a ROM that does this on its own?

Are you only looking for a software solution?

Ideally. My TV does not have analog outputs and my audio setup does not have digital inputs.
I know there are audio adapters, but this is far from ideal, especially considering that my TV does not have selectable PCM/DTS out, meaning I would have to buy a $65 output for the TV passthrough (one that handles both PCM and Dolby streams).

Dark Side v8 can output audio from s2 headphone jack, I have a monitor without speakers, and I have to use the headphone jack to amplify the volume when I use a mhl adapter for videos and games.
