[Q] MHL for audio, possible?

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

[Q] Just ordered MHL-HDMI cable - will it transmit Spotify to my AV receiver?

I'm looking for a way to play both Spotify from my SGS2 through my Onkyo AV receiver to my speakers, as well as just play videos from my SGS2 through the Onkyo so that I can watch videos from sites like charlierose.com (which uses flowplayer), etc. on my TV.
Should this work? Anyone received their cable from play.com sooner than expected? Hoping it doesn't take the 1-2 weeks.

And what about this cable ?
http://www.dealextreme.com/p/ca-156-usb-hdmi-adapter-cable-for-nokia-53688
It is for Nokia but Nokia also supports MHL so I assume it can be used for the Galxy S2 ??

That doesn't look like a MHL cable to me; the small end should have a 5-pin micro USB, and the MHL-to-HDMI conversion requires a bridge chip, which needs to be powered, which is why the other MHL adapters require you to plug in a charger.

its actually not a usb cable at all.
its a second cable packaged with the n8 that plugs into a mini-hdmi port on the top of the phone converting it to a regular size hdmi socket to connect to a screen..
still useless for the sgs2

can micro usb send audio out ?

For my in car solution, previously I used a brodit Active dock which you could plug an iphone cable into the bottom of, that cable I used previously for iphone was one iphone port in, but had an audio out as well as usb charge cable, so I was able to jack into my cars 3.5 Audio port and the other end into a usb cigarette port adapter, it was commonly referred to as a Y Cable.
I am looking to do similar from the Brodit Active HTC One X dock once its released, and ideally use one cable that plugs into the docks micro usb port (which the HTC One X plugs into in the dock).
So, a) does the micro usb port on the phone support sending the audio out ? and b) if so, does anyone know of a cable that will split out to an audio and usb end such as I described above..
Thanks for any help anyone can offer.

Mart

to give some context, I used a cable like this one for the iphone and active brodit dock before..

The USB does HDMI which carries audio. Someone with more knowledge will be along soon I imagine though, they'll be able to point you where you need to be!

thanks for the hdmi headsup.
Anyone else able to offer a solution ?

HDMI is digital though, so to use with a standard 3.5mm Aux you will need a digital to analogue converter. Assuming it cant switch to analogue... its a bit up in the air at the moment, need to wait for a few devices to hit the shops :/

All you need is-
Micro Sd to car adaptor for power.
3.5 jack to 3.5 from phone to stereos aux in.
You can call, use sat nav whilst listening to music.
Will mute music for ditections, phone call whateva!

You can also make a cable and connect them to the pins on the back that are used for a dock.

Thanks for the replies. I already have two separate cables wires in for aux and for usb, but I wanted to try and have only one cable so I could literally attach one and not have to plug both in and out, hence the year cable idea of

Help with Otg

Hello i installed a nexus 7 in my car not i really dont want to take out my center console because its a huge Pita. But i realise that i now need an otg. I was runninh sound via bluetooth to my radio but the lag os crazy. I have acces to the the end of my charging cable. I was wondering would adding a usb to usb adapter and a usb hub. Would that be consider a usb otg cable. Would i be able to purchase a usb dac and use it. Also could i charge at the same time. I have absolutely no room to fit a audio jack on my tablet. So usb dac is my only option.

You generally need a kernel installing to do as you have said eg elemental x or timurs. Yes, you can then use a usb otg cable to power and host the usb dac.

USB C to HDMI

Has anyone gotten one to work I bought 2 from Amazon and none seem to work. Maybe I thought wrong but thought HTC 10 has displayport output.
Sent from my HTC 10 using Tapatalk

I tried one at work last week, worked fine. Not sure what kind i got, but was not a problem.

OK thanks... I'll probably go to Best Buy and see if I can test one out there. Hope I don't have a bad port

I've tried 2. One worked, one didn't. Both were designed for macbooks, so ymmv.

I will try this out when I get the chance.

Tried one at the Computex last WE, for MacBook. Didn't work.
And after I tried the HTC10 and put it back to the MacBook it didn't work at all anymore.

damn thats not good news. still haven't had the time to head to local bestbuy. Hoping someone got one to work and point to an amazon link really miss having to show movies (for my kids) on the screen. Still have my MHL adpater for htc m9.

Adapter needs to use display port protocol, not mhl. Some adapters (USBC to HDMI) will use mhl internally and won't work (to my knowledge). See USB-C thread in 'Real Life'? section.

Yes I know can't use MHL for HTC 10.. Just saying I miss that feature. And almost nagging at me still is the MHL cable. starring at me saying why did you get of the M9 [emoji14] you could be watching videos on the 70inch right now.

Buy your nagging mhl cable a baby sister; a USB-C to HDMI port adapter / hub. It uses display port protocol and supports 4k. Adapter also includes USB 3.0 host port (so OTG) and 2nd USB-C port (for charger connection, I think optional, but I always use). Charge phone and watch at same time. See referenced thread for source. Win-win but approx $30. Need standard HDMI cable. Works well for me.

I ran into the same problem the mac pro adapter, it would charge or display not both. I went this route Microsoft - Wireless Display Adapter V2 receiver - Dark-Titanium and use HTC connect. It works great.

Just curious... you've had no problem charging this way? I wasn't sure if the 10 could take a regular USB-C charger or if it needed a QC compatible charger.

Partial answer. The HTC-10 does not need QC2 charger, just might charge slower or at various rates supplied by charger. I use several different chargers I had for my micro USB phones. Both using micro-USBC adapters, and USB-C cable direct. What I haven't tried (per your question), is fully charging via the mentioned display adapter. I doubt that the will recognize it as QC2. I will try this with the HTC supplied charger.

Sorry for the bad video; as it was taken with my Nexus 7.

Thanks for this, will be ordering one myself now.
edit: no audio out on this device, well then that sucks. Not good for watching video, yah I know I probably can use headphone jack for that but should work that way in my opinion. guess I'll still be on the hunt for a simple HDMI and audio output like the good old MHL adapter.

Is this available anywhere else? I was hoping to find this or a similar device on Amazon or something but nothing else has been confirmed to be compatible. Is your experience with this device still a positive one??
Also, I am assuming that if you want to supply charging power to this device you need to use a non-QuickCharge charger as supplying greater than 5V to the electronics in this device would be bad...? What about still using legacy USB-A to USB-C cables (like the one that came with the HTC 10) with the 56K Ohm resister?

I use mine all the time at work for about 3-7 hours a night (5 nights a week) - have it plugged into spare monitor to watch youtube etc.
I using the default charger that came with the HTC 10 and only gets slightly warm (charger & adaptor) when I been playing games for a hour or two.
Been thinking about purchasing another one as a backup.
