Hi, I'm wondering if it would be possible to connect the HTC one x with it's micro USB port to a coaxial input on an amplifier. This without the use of an AD converter.
I bought a wadia powerdac 151 mini and would love to do this.
If there is no possibility I would like to know if there is an other high end smartphone that could pull it off.
Ps I know there is a second component in the wadia line that has an iPhone connector, I just don't want that component nor do I want an iPhone
Thanks in advance!

Hi,
Can think of some ways to do this but they are not at all elegant:
You can get digital output via HDMI by using an MHL adapter. Since your amp doesn't have HDMI inputs you would also need to get an HDMI to SPDIF converter like this http://www.amazon.com/HDmi-Audio-Converter-Convert-Video/dp/B0015DTUJ8 (there may be something similar with coaxial). There are other messy ways of doing this such as passing HDMI through a TV and back out of the TV via SPDIF - but you would need to keep the TV on to get audio.
Similarly, some of the above could be done with WiFi using the the HTC media link HD instead of an MHL adapter.
Alternatively, you could use Bluetooth lossless APT-X. However, the receivers I can find only output in analogue, which is not much use to you. And bluetooth is only good for streaming music - video would be out of sync.
Digital Audio Out via USB on HOX Jellybean confirmed working!
Hi Guy's n Gal's thought i'd make every HOX owners day by confirming that USB audio out is now fully working on the HOX!! :victory:
I purchased the Fiio E17 and recieved it today 04/01/13 my HOX is a Orange branded Tegra 3 phone which is running custom firmware (Android Revolution HD 18 Jellybean 4.1 Hboot 1.6)
I charged the Fiio E17 pluged it into the HOX with a USB OTG cable, plugged in headphones hit play on poweramp and to my huge delight and relief awsome sound was to be heard Eureka!!
So to everyone with and Android device capable of running Jellybean that wants Digital Audio out via USB It's a reality.
Enjoy and spread the word.

What cable did you use? MicroUSB to usb then usb to mini usb? Or microusb to spdif? Or straight micro usb to mini usb (e17). Thanks.

You first need a usb otg cable. It's micro usb male win a female usb on the other end. Then plug your jab sound device (like the fiio e17) into it and hey presto. I have used this with a cheap usb sound card and it works so i imagine you can find a usb device that supports the output you need.

While researching ability to use USB DAC while charging the phone in the car I found this video. The guy clearly says that tablet is charging while accessing all those accessories via USB OTG. Similar cables are found on ebay, called "USB OTG with power".
The big question is: would the Galaxy S3 actually charge while using USB DAC at the same time? It should be possible, but I don't have the phone yet (still considering it), nor do I have the cable, nor a USB DAC In theory it should be the same with any accessory - can someone actually confirm either way, whether phone can or can't charge in USB OTG mode with similar cable? This video shows similar setup on Galaxy S (only it's normal OTG cable, USB hub, usb Y-cable and card reader) and it's definitely charging while mounting USB devices! Will S3 do the same?
I fear that upgrading from Galaxy S with voodoo control of Wolfson chip to north-American S3 with worse audio path might not suit me if there's no way to power the phone and use external DAC at the same time in the car... I hope there is a way... I appreciate any advice and opinions.
It's a first time I see such cable...All I read was people saying it's impossible in the first place. Well, hopefully in 2 weeks I'll be able answer your question

Looks like it's possible on some devices, but not with Galaxy and Nexus family... But it would be great if you can confirm that, so let me know if you can try it. Thanks.
Finally got the cable.
The result - nope, doesn't charge
Maybe the "Allshare hub" could do what your asking for?

Sonic, any luck with your friends phone? Really looking foward to your results :fingers-crossed:
Do you have part #s for the variable resistors in your samsung post or at least where you got them from? I would be willing to try some things out if I could find the right pieces. What I really want to get my hands on is the MHL adapter that was shown off with that spider laptop at IFA a couple weeks ago..
SUCCESS!!! I can confirm that this USB OTG cable (http://ebayitem.com/190710044655) DOES CHARGE MY GALAXY S3! I plugged in USB cardreader with SD card into the phone through this cable (it lit up and card is fully readable), then plugged USB cable end into PC and phone showed a charging icon! Moreover, after waiting for 5 min. with screen off (cardreader still glowing blue and working) battery has gone up from %72 to %75 (and while I was writing this, to 78%), so it is indeed charging! Yay! It probably won't get up in the car, where just phone alone is "not discharging" at best from the car adapter, but at least it should allow me to listen to music with quality DAC and use navigation without (or with minimal) discharging.
I have not tested it with USB DAC that I intend to use for my car (Behringer UCA222), because I have to go out and buy it. Hopefully it works. Anyway, this cable definitely works with simultaneously charging my north-american Samsung Galaxy S3 (from Bell Canada) while powering USB cardreader!
Somebody else has mentioned that another cable (http://ebayitem.com/120980364117) also worked in his Galaxy S2.
I bought Behringer UCA222 USB DAC and tested it in my car with the USB OTG cable with power that I mentioned. It works great! And the phone is indicating a charge. Sometimes when first playing music after plugging the device it sounds like fast forward for a few seconds (I guess clock rate mismatch or something similar), but after the presumably clock is locked it plays perfectly fine.

That is outstanding..gonna order one of these guys right now.
Here is a better link for all the ebay listings. Be aware of the differences, MicroUSB adapters would allow you to use your existing charge cable to plug into it while the standard USB would require you to be very close to the charger or have a USB A-A cable to attach to a power source.

The problem is that apparently not all of those cable work in terms of charging the phone. People say mostly that it doesn't work. The only guy mentioned success is with the cable I bought, but he then confirmed it with another, more convenient cable. I have the one that needs a USB extension cable to reach the charger, but it's about a buck on ebay, so no problem there. But not all cables work this way: most reportedly will allow you to power USB accessories but not charge the phone.
I found that this configuration works for charging while in USB HOST mode:
S3 -> standard otg cable -> Powered USB2.0 HUB -> devices (keyboard, usb dac, usb hdd...)
The only catch is that the hub must be powered before you plug in the phone or the phone will try to power the hub and will never enter charging mode. I'm using this setup in my car and it works perfectly. As long as I start the car before plugging the phone, we are good to go.
I only confirmed this works with AOKP JB builds. No idea about other roms/kernels. Hopefully this helps someone.

I got mine in the mail today (ordered 10/16) and tried it out as soon as I could. I can confirm it charges and allows for OTG at the same time. This is the auction I bought from: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=251127542280&ssPageName=ADME:L:eek:U:US:3160
Hello y'all. I'd like to ask your attention to this thread, especially but not limited to sonicboom and others, I really could use some help.
I just recently got a Samsung Galaxy Note 10.1 and so far I'm quite happy with it --- except one thing, I cant find a cable that lets me charge the tablet *and* use the USB Host (OTG) port... (i.e. read files off a USB drive or play a game with a USB game pad while keeping the tablet plugged in)
Is there a way to do this? it would seem to me that all it needs is a splice to give power to the Power +/- pins on the connector while keeping the OTG Data +/- pins active...? (I know nothing about the pinout so I could be wrong on this)
Just to be clear I want to use the OTG adapter WHILE CHARGING (I've found one device that gives both these options but says "only one function may be used at a time")
Ideas?
Discussed dozen times in 10.1 forum. Actually it is not possible. Build an otg + power cable myself but it only works with timing and with a specific procedure... quite annoying. Wait for a custom rom somewhere in the future as I do.
You may have issues trying this, OTG cables are iffy under Jelly Bean. Some may work, some may not. In fact, Google removed references to OTG support for Nexus devices last November since OTG is so spotty. Splicing a cable that might work may kill it. Decent battery-powered USB and SD hubs are available and bypass the OTG problems. I have the RavPower RP WD01 and love it. The USB port will support drives upto 3T. It also has an SD card slot.

Powering the USB devices isn't a problem, I have a nice hub that powers them without issue, even extremely power-hungry devices. I was wanting to charge the tablet's battery while using the OTG adapter (original thought was for USB-gamepad-ing since high-requirement games drain battery, but I've since started using a PS3 controller over bluetooth so I can use the OEM charge cable and wireless for gaming --- but USB drives I'd have to copy the files over to internal flash or a MicroSD card to view while charging and i've found that the cards dont like files that are 8gb in size... (FAT-32 restriction iirc))

I saw that when I google'd but thought maybe there had been some new developments (especially with how this site's members love to tinker with electronics and write custom firmware). It's not a huge issue, since the Note 10.1 has amazing battery life (it's actually matching or doing BETTER than my iPad in most circumstances) I just like to never run the battery down low.. (why cant tablets have user-replaceable/swapable batters like most phones?!)
Thanks for the info!
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 USB-A OTG Cable -
Not able to power a simple external USB MSata Drive or External USB HDD - I plug these drives into a LG V10 or a Galaxy S8 and work perfectly fine. What gives? I have only able to get a flash drive to work.
Any known work a rounds? Anyone else try this?

I tried this just now and am shocked it doesn't work either.
I wonder if OTG power support was removed due to the decrease in battery size? Has anyone tried OTG "audio output", say through a device like the audioquest dragonfly, to see if that works??

I don't think so, since the notification that pops up when I connect 32 GB ADATA USB 3.0 flash drive -> USB 2.0 A female to micro-B male OTG cable -> micro-B female to USB-C male adapter -> Z2F says the Z2F is providing power to the connected device. The problem is you can't do anything else BUT that.

I'm wondering this myself. The fact that the Z2F outputs analog audio over USB-C leads to me to believe that it isn't fully USB-compliant.* Both the HTC U11 and Google Pixel 2 output digital audio, which, based on Google's crowing about USB-PD and the existence of devices like the dragonfly, appears to be the right way to do things (albeit with the tradeoff of more expensive audio peripherals, which much now have their own onboard decoding hardware.)
*Can anyone with knowledge of the USB spec comment on this?
BTW, I started a support thread about this at the official forum, where it's received several replies and suggestions from a mod. Kindly chime in there too so Lenovo can see this is a real issue they need to address.

So based on this Motorola mod post and the OP's statement that USB-C flash drives work, the Z2F and Z have the same (lack of? LOL) OTG functionality. The Moto Z subreddit has a pretty extensive thread about Moto Z DAC functionality; it appears the Dragonfly is supported, among others.

Interesting development: another Motorola Forms mod now says powered USB hubs are rumored to work. We're making progress, folks.
Okay fellas,
I so far have been able to get certain drives to work and others not! I have tried 2 different USB-C to USB-A cables and get the same results, 1st ones an HP cable and 2nds an Anker USB-C to USB 3.1 Adapter
https://www.amazon.com/gp/product/B01COOQIKU/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
I have been able to get a 256gb M2Sata Drive, 500gb WD Mypassport, and a 2TB Mypassport to read.
I also have a 256gb MSata Drive that will not power up or read without using a powered usb hub. However the Msata Drive will read without an added powered HUB. On the Samsung and LG Devices.
Only thing I can think of is that certain drives have higher amperage that the Moto Z2 simply cannot push through its USB-C Port.
Good to know it isn't just me experiencing broken USB OTG support.
I've got a PS3, PS4, and Xbox one controller I hook up with USB OTG. Normally it's as simple as plug n play and I'm good to go. However, that doesn't seem to be the case here. I can still pair the PS3/4 controllers in sixaxis just fine and get power to the PS3/4 and Xbox one controllers. And yes, that bit about supply power to device rather than transfer and you can't pick something else, happens to me too. Sometimes I can plug my thumb drive in and I can explore through the storage file explorer, but I usually have better luck with an app called X-Plore.
This one time I even had said thumb drive take out my entire OS to the point where I had to use that June ROM to reset me back to start. Spoiler alert: I kept getting "Android.process.acore keeps crashing" over and over; various other apps kept crashing as well.
On a side note if I can at least get PS3/4 controllers to work for a long time within say, sixaxis (or similar) I'd appreciate any tips. Otherwise I either gotta wait for this to be solved in a future upgrade, future sixaxis, or when we start getting custom ROMs..

The latest Neutron and USB Audio Player Pro will output bitperfect (non upsampled) audio perfectly to both my portable DAC/amp units.
USB Audio Player pro, has the benefit that you can stream tidal native, bitperfect if you have an acct. Which is awesome imo. Tidal still buffers SUPER slow on this device though. So I'd recommended only offline use (which you CANT do with USB audio player pro due to licensing)
I would also add that I get some scratchiness out of the stock USB C to 3.5mm dongle that came with the phone. I thought it was the port being "dirty",. but I have NO NOISE out of the USB audio output using the Anker otg cable. Maybe Anker makes a USB c to 3.5mm adapter.
One tip for getting USB powered OTG drives to work is to use as short a USB cable as possible. Like get a good quality 1ft USB cable. I used to have a similar problem with using an external drive on a Wii and found that a 1ft cable would allow me to use 2 different drives that otherwise would not work with a 6ft cable.
It worked!
I used a USB 2.0/type C adapter that cames with s8 and instead the original USB 3.0 cable, put another adapter, and transferred files with Total Commander.
On this subject but kinda off topic. How are you all getting your drives mounted? I cannot mount NTFS or fat32 drives. Only ext3/4 drives.

Yep, basically you created a 2 inch cable. LOL.
In essence, many USB powered hard drives approach the power limit of what the USB port can output. Power drops over the length of a USB cable, so longer cables may not provide sufficient power for the drive to function correctly. Better quality cables usually have less power drop, though it is not a guarantee.
Unfortunately most USB powered drives do not list their power requirements. The only way to really tell is to open the case for the USB drive and look at the hard drive inside it to find how many amps it draws. For the best compatibility you want the lowest amps.
I don't think that's otg power issue. I think it is locked by Moto becuase they want you to use their add-on devices. I have a wifi camera it doesn't work either, But it works in my all other phones

Just because an add-on device works for one USB OTG implementation doesn't mean that it works on all USB OTG implementations. There is an enumeration of what devices and types are accepted. I have tested USB OTG audio microphones, USB OTG audio speakers, USB OTG Headphones, USB OTG Ethernet, USB OTG Keyboards, USB OTG Flash drives and those device types work. If there is no device driver for the device attached then it would need to be supplied by an app. OTG power drain is definitely an issue and is mentioned in the OTG specifications.
That's what I tried to say. It is locked by Moto. They want you to use their add-on mod. I have tried extrenal usb c endoscope camera, wifi endoscope camera, lg wireleas projector, Samsung projector. None of them work with Moto. However, the same apps work in all other phones. It is clear to see, it is not all otg related all the time or driver which provided by app. It could be just locked by Moto, becuase they want use to use their mod add-on. People who rooted the phone was able to turn on those supports.
I use a Belkin OTG adapter, it worked but it was extremely picky. The Built in files app only picked up my HDD if it was either Fat32 or exfat. But the ES File Explorer app only picked up NTFS.
