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

looking for a cable

I'm looking to go from the Xoom to my truck head unit. So HDMI mini to composite, do they make this cable and which HDMI mini is on the Xoom?

There is no such thing as this cable you ask. HDMI is digital, composite is analog. I assume this is a DVD player or something...long story short, it's not gonna happen. If you wanted to throw down a ton of money you could get a transcoder (possibly).

this could be something for you

HTC One x connection via MHL adapter.

Hi Guys,
I have the one x, Optoma pk301, MHL adapter and the required HDMI cable. Got the connection all set up but I'm unable to get a display on the projector. Are there any settings in the phone that i have to change/switch on to display on an external screen?
Thanks

Mine worked right out of the box. I used a Galaxy SII adapter. As soon as i connected HDMI, charger and phone, it switched to landscape mode and the picture showed up on the tv.
As far as i am aware, there are no settings on the phone to enable/disable MHL.

Did you plug the USB to charge ? It says no power > no video

Im using this one:
http://www.amazon.com/Samsung-Smart-Adapter-Galaxy-Mobile/dp/B005MR82GA
Its working now. Was displaying a red X before. Didn't do anything other than just unplug and re plug everything

Can you tell me if I play movie on my TV by mhl cable, does it shows external subtitles (.srt)? And, can hox play movie on TV with phone screen of during.

"Micro USB to HDMI® MHL Adapter - Black" - quick review
I just received the MHL adapter from MonoPrice, about $10 US:
http://www.monoprice.com/products/p...=10833&cs_id=1083314&p_id=8805&seq=1&format=2
The product description implies some phones can power the MHL adapter, with the One X you must supply power via a micro-USB charger. Be forewarned, the load may be a little higher than what some phone chargers can deliver; my EVO 4G charger would shut off after about 10 seconds, an old Nexus One charger worked fine.
Output is 1280x720 60Hz (should auto-adjust to the TV, don't have a PAL display here to confirm this). The Samsung HDTV was set to "Just Scan", meaning no scaling is done by the TV.
The resultant HDTV image is underscanned by about 35 pixels on each side, 20 pixels on top and bottom, resulting in a display area of 1210x680. I think this is a problem with the One X GPU drivers, and not the adapter because I doubt a simple device like this can do any scaling. At CES, I played with a few Transformer Primes running Shadowgun Multiplayer, mirrored to HDTVs at 1280x720, and there was no underscan, so this is likely not be a limitation of Tegra 3 GPU.
I got the red X once (displayed on the TV), afterwards it would not mirror the display to the TV until reset, so the connection handshaking is kinda finicky. I've been plugging the micro-USB power last, after the phone and the HDMI is connected and the phone is powered on. Sense should flip into landscape immediately, if not, something is wrong. If you power on after everything is connected, you should see the lock screen in portrait for a couple seconds, then it'll rotate. Sense works surprisingly well in landscape, I'm surprised that HTC didn't allow this mode without an MHL adapter connected.
There is a slight performance hit on the One X when display mirroring is active:
GLBenchmark 2.1.4, native display:
Egypt Standard: 48 fps
Pro Standard: 54
GLBenchmark 2.1.4, HDMI mirrored:
Egypt Standard: 42 fps
Pro Standard: 52 fps
If you want to demo a One X, play Shadowgun THD on a HDTV, it looks absolutely amazing. You are "playing blind" on a touchscreen, but once you get a feel for turning and shooting (right thumb), it's pretty easy. Ideally, this setup is screaming for a game controller, but I haven't come across a thread about this yet for the One X. Support for analog sticks has been in the OS since 3.1, so the keymapping utilities on the Market shouldn't be necessary, but I need to look into this further.
Note: the images were taken of the HDTV using a point-and-shoot and scaled to 720p, so you can see the degree of underscan (the unfiltered decimation is very visible in the fonts).

The TV is full HD, the phone passes 720p through the adapter, looks like it's a direct mirror.

Yeah, it doesnt work if you dont connect the power cable to the adapter.

And subtitles? Are they on the TV please?

Looking nice on the tv

Everything you see on the phone is mirrored on the TV. If you are watching a movie with subtitles on the phone, you will obviously see them on the TV.
My best experience so far watching 720p & 1080p has been with MX Player, but a lot of people also use Dice and Mobo.

That was not the case with my sgs and tv out and as far as I know with sgs2 tv out via mhl. It's mirroring everything but subtitles.

hi i have two days htc one x and have two hdmi cable to tv but same result no signal what i do wrong i use this one please helpme

I bought a MHL adapter from Mobilefun and I get the phone picture on a my PC monitor, with a little pixel loss as described by rasterX.
However I tried looking at a video I recorded with the HOX. I played the recording using the stock player and MX player.
In both cases, the playback is too fast on HDMI, it's like pushing a fast forward button.
With MX player I tried the different options (hardware/software): hardware is too fast, software is variable: complex pictures are too slow to display, less complex pictures are shown faster but since the display time changes according to the picture, the software playback is useless.
I tried two different PC monitors, one is Philips with a DVI-HDMI adapter, the other a DELL with a direct HDMI input, results are the same for both. I'm in a 50Hz country (France) if ever this can have a side effect...
Anyone has similar issues with MHL?

I tried my Samsung MHL adapter and it worked. My TV resolution is 1366x768.
When I connect all cables (inclusing power of course) I get portrait screen on my TV. As soon as I play movie or game, it goes landscape. When back to homescreen, it's portrait. No issues in Diceplayer or MX Player. Worked in HW and Software. Software mode allows to see subtitles on TV.

Sound only out of one channel
I only seem to be getting audio out of the left channel. I've tried 2 MHL adapters, and 2 different HDMI cables with 2 different TVs.
What's going on!?

HI Jammy, I will test it.
What player are you using? MXPlayer or stock. what sort of files?

I'm having the same problem, only left channel is working on TV over mhl adapter and if I plug headphones in one x 3.5 mm jack it is OK. I tried BS PLAYER and MX PLAYER.

Same symptom here!
hmm ... bug?

is it possible to use analog video out? AUX?

I would like to connect my One X to my carstereo with the AUX input, so i can see spotify and the whole screen in 7/8" I only find stuff for USB to HDMI output, worked with my old Samsung Galaxy 1 to get analog video from the 3,5 mm audio output. Is this posible some way with One X??

I think HTC used to make devices capable of AUX video out, but I don't think they have done so for a few years.
Looking at the spec sheet, the only TV/Video out the One X is capable of is "TV-out (via MHL A/V link)" which is microUSB to HDMI which most new phones have as standard. It's annoying one wasn't supplied with the device though

DEX: USB-C 4K video output

I have read that the Samsung Galaxy Note 10 series can video output [email protected] using USB-C. Can anyone confirm that the highest video resolution output is 2160p?
