A similar question has been asked on modaco but I don't think a solution was found. Therefore I am going to ask if this would work here.
Is it possible to connect a micro usb (male) to mini usb (female) adapter up to this thing (HTC 4 in 1 adapter: I can't post link because I am a new user but just search it on youtube). This would connect to the tg01 micro usb and provide a 3.5 mm audio out in addition to a mini usb connection where one could potentially hook up a charger. I was thinking of testing this out as it would cost about 10-15 dollars but I do not want to damage my phone in the process. I have no electrical engineering knowledge but maybe someone else can explain if this would work before I order anything.
On a side note: I order samsung WEP870 bluetooth headphones on sale as an alternative to this. Note sure how sound quality is but I will try answer any questions you guys might have.
Any input is welcome.

I was heavily involved in the discussion running on MoDaCo you refered to; unfortunately there has been no breakthrough on this issue to date.
I did look into the the HTC adapter you mention, but it actually uses the proprietary HTC ExtUSB plug on the input end (connecting to the phone) and NOT a normal mini-USB. The ExtUSB has 11 pins which include a discrete audio output (being used to feed the 3.5mm jack socket) and also hard-wired power (used to accept the charger input).
In the case of the TG01 uUSB socket, it is too 'intelligent' for its own good. Every function, charging, audio out, USB data transfer, etc., is under procesor control. Different functions are triggered by the device 'seeing' a certain resistance across the sense pin and ground; depending on this the processor then configures the use of the socket pins accordingly.
I am after what you are trying to achieve also; there is a chip supposedly available which is intended to fulfil exactly this functionality, but I've been unable to find any devices on the market which use it and attempts to contact the manufacturer with a view to getting a few samples to try and build an interface have so far been unsuccessful.
I've attached a couple of documents which explain the uUSB Charger Adapter and also the chip spec sheet for reference.

If anyone else knows anything to help move this one forward, will be much appreciated !
Thanks for the nice explanation,
Hopefully one day there will be an adapter that can make this possible.
Hi all,
Has anybody tried using the HTC Sensation's HDMI output to get digital output?
What I had in mind was (and this is going to add up to be extremely expensive), the microUSB to HDMI cable, an HDMI to component/digital audio breakout chunk (for example, at least HD Fury 2 has possible (!!) battery-less operation), converting that audio cable format over to something your battery-powered DAC can use (probably spdif), and then connecting your DAC to your amplifier (or, having your DAC/amplifier be the same package).
Has anybody tried this? Had any experience with something like this? Would this kill the battery (I assume draining the HDMI power line would)? This is just a crazy idea I had after reading about the (reportedly miserable) audio quality the Sensation has.
Let me know; thanks!
the hdfury2 does have an optical output so you could use it, problem is the hdfury2 does require power from the hdmi device its connected to and question is would the phone provide any power? the hdfury can alo be powered by a standalone psu as not all devices can power it.
you would also need an MHL Adaptor and not a micro usb-hdmi cable.
will any audio app output in this way, its probably unlikely so all depends on the phones software or a custom app to route the audio data.
personally rather than wasting money on adaptors and so on just buy a new amp with the money, one that has hdmi inputs.
an app that can use the usb host mode and output the data by standard usb protocol to your DAC would be best (just like how its done on a pc)

Right, that's what I'm asking. Basically, there are two things: 1) can it get the power, and 2) can the audio software on the Sensation provide only audio through HDMI (or would it otherwise route it to the 3.5mm jack anyway, like some of the Cowons I had).
If these two are possible, then the setup should be relatively easy. Portable amps generally don't have HDMI inputs, as far as I can ... tell.
I'm not sure how much low-level hacking you'd need to do to get the USB-audio protocol...
Thanks for your input!
Hey, I had a good search and found a lot of general info on this but I couldn't find anything specific to our device, so here goes:
Has anyone had any luck using a USB headphones amp / DAC with their One XL via USB OTG? I'm looking specifically at the FiiO range but would love to hear of any others that have been confirmed to work. I'm hoping for a very confident "it'll probably work" before I spend $++
I'm running the latest AOKP 4.2.2 release preview (Rohan). I have got various USB peripherals working via a $5 OTG cable, including a keyboard & mouse and memory stick [StickMount didn't work but I was able to access the contents under /mnt/usbdisk just fine with ES File Explorer].
I'm happy flashing different kernels but don't really have experience manually editing linux system files.
I've read / skimmed most of this monster thread on head-fi, and the consensus seems to be that YMMV depending on the two devices, USB DAC and phone, used: http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/1320
I also have a Nexus 7 that I would be far less concerned about breaking in the name of research, and I also happen to own the Logitech G930 gaming headset that some people have reported success with with Android, so I might have a crack getting that to work before I buy anything else.
Cheers!

After you skimmed some one posted a master update:
http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/1785#post_9215106
I want to believe that most of the diy dacs will work because 90% use a PCM2707 to talk to the usb. Then either they use the pcm2707 internal decoder, or feed the is2 signal from the pcm2707 to a higher quality dac
My issue
Hi everyone, I have a Nexus 6P and want to route my audio through a USB type C converter to 3.5mm headphone Jack. I have purchased one online, but it doesn't seem to be working. I have seen that the Moto Z has this adapter and I assumed one I found online would be compatible with my 6P. The reason I want to do this is because I prefer for the AUX jack to come out the bottom of my phone.
What I have tired
Changed 'Select USB Configuration' to all the different options and tried playing music.
Tried 'audio routing' apps from the app store
What I would like to know
Is this because I need to change a setting in my phone to route music out of the USB C?
Do I need to get some kind of DAC to allow support for this?
Has anyone else tried this with their phone?
Thanks

If you don't mind my asking, why bother?

One reason is that to me it makes more sense to put your phone upside down into you pocket. I've always done this at least. So when listening to music I have to put it the other way round. I have also heard the USB C port offers better sound quality.

Re:sound quality, you'd possibly see a quality increase if you use an external Digital to Analogue Converter or fully usb-c headphones. BUT, if you're using a little dongle (if it's possible), then the phone is still managing the analogue conversion and, thus, a very similar quality of audio output. Now I don't know of the 6p's ability to pipe it straight out iPhone 7 style through a dongle, but short of buying a DAC and going whole-hog on an audio upgrade, I'd just flip your phone the other way in your pocket and go the standard route.
Just my $.02
I have been looking for a solution to this too and I seem to have found one. I poked around on Amazon and I think I finally found adapters that work, here's the link https://goo.gl/QT2ith This the only one with positive reviews so when it comes in on the 30th I'll let all of you know.

Looks quite similar to the one that I got. Hopefully it works for you! Let me know how it goes
I read recently that the current implementation of audio over USB-C isn't very efficient or battery friendly. There's a new spec being ratified to provide audio like the iphone can. Hopefully that's a firmware change and not a hardware one.
http://www.theverge.com/2016/8/17/12519936/intel-usb-type-c-headphone-jack-replacement-idf-2016
I don't think it's possible on the 6P, not without using a USB DAC anyway.
As far as I'm aware, the adapter you have is for a USB 3/3.1 interface. While the 6P has USB-C it is USB 2.
I'm able to get audio out of my USB C port, but it's with a USB headset. Haven't tried it with a 3.5mm headphone adapter, but havd no reason to try it either.
This is weird. Because i have a pair of Sennheiser Urbanites (Wireless edition), and i can use bluetooth, aux, and usb (like for a computer) audio. I once tried to turn off the headsets (bluetooth off, aux and usb still works if connected), and turned off bluetooth on my phone. Then i used my USB type C to USB type A Female adapter (from the google store), and connected the usb-cable from the headsets into the type c adapter. it did output audio through the usb-cable.

Bluetooth headphones usually have their own DAC, so the audio for all but the Aux is still being sent through the DAC first, which is supported by older USB standards.
The new USB 3.1 Audio standard can pass through analogue audio from the internal DAC, which is what I believe phones such as the Moto Z utilise. Otherwise the adapter would require it's own DAC, which would make it far larger and more expensive.
Not sure if you will find a good solution at the moment since they just created a standard for audio over usb c http://www.businesswire.com/news/home/20160927006252/en/USB-IF-Announces-USB-Audio-Device-Class-3.0
Did the amazon converter end up working for you?
My experience so far.
Hi, I ordered some usb c to 3.5mm & out of the box so far they aren't working. I tried Neutron and tried to force the audio to usb but unsuccessfully with phone not recognizing the USB connection.
On the other hand the type C to usb-a adapter worked beautifully using mixplorer. If I get working, will update. Thanks.
Is there in planning USB-C alternative mode for audio? What would be the best way to promote this or could some mod put this topic to a subforum that is likely be read by people involved in USB standards development?
Why would we need one?
In wake of Apple smart device developers are getting rid of 3.5mm headphone connector. USB-C headphone adapters currently in market seem in general to have very low audio quality and low audio output power. Main reason for this is probably that a DAC has to be implemented inside the adapter with very limited space and price constraints.
99% of smart devices have a DAC because they have speakers and mic. By all likelyhood the integrated DAC is of higher quality than ones inside USB-C - 3.5mm female adapters. Maybe even audio signal could be stronger (based on that it is stronger on smart devices that have 3.5mm output).
Typical scenarios where this would be useful.
- smart device used as a musical device (synthesizer or digital audio workstation (DAW)) where you need low latency for audio.
- smart device used as a music player in scenarios with unreliable wireless connection and desire for audio without lossy compression.
- interview scenarios, games..?
