1. Attach USB OTG adapter's female USB-A to a USB cable connected to DAC.

 

2. Attach microUSB end o USB OTG adapter to Android device.

 

3. Wait for acknowledgement of connected USB device, or restart. If it doesn't work, you'll need to root the device.

Plug & Play, if every USB audio-required component is functional.

 

Required software

It depends on your Android device: native USB audio (i.e. USB audio-enabled Android device) or eXtream USB audio (i.e. USB host-enabled Android device with the USB Audio Player PRO app available on Google Play store).

 

 

 

 

 

Required hardware

To work with an Android device, which is a legacy USB peripheral, a USB OTG adapter (i.e. pin 4 connected to pin 5 micro USB plug to standard A receptacle cable adapter) is needed.

A USB OTG adapter switches the USB OTG capable Android device to USB host mode:

Android device with native USB audio or with USB Audio Player PRO > USB audio out >> USB OTG adapter + regular USB cable provided by the USB DAC manufacturer >> USB DAC >> amp >> headphones

 

In order to be sure that the USB OTG adapter is functional (i.e. the pin 4 of the USB OTG adapter is connected to its pin 5, so that the Android device is configured to USB host mode able to interwork with a USB peripheral like a USB DAC), let’s test it with a simple USB peripheral like a USB mouse:

So does that mean if your android device does not natively support usb otg audio out, then it is impossible to use a dac with other music players like spotify?? :( boo that is sadness.

That's the problem, No Spotify, Google Music (All Access), or any players like NeutronMP or PowerAmp. So it's more than just streaming apps. I'm not a fan of using dedicated apps that play files via the USB. So your mission is to find a DAC that works with your Android device. Hopefully your Android device supports USB Audio and does it correctly or else you're SOL.

Thread Starter 
Most of the manufacturers are on board here - Samsung, Sony, LG and HTC are all working properly with USB audio. Only difficulty is that their implementations are not universal as Google is not showing any leadership here, so not all DACs interwork with phones from all manufacturers.

hi everyone,

 

there is stil no way to find that kind of otg cable with two elbow connectors ??

 

http://www.jdslabs.com/products/86/micro-to-mini-usb-otg-cable/

 

i think i've already asked on this topic but i was hoping things would evolve with all the new small usb dac recently announced.

 

With some help here i've found this one but it is mini b to mini b usb (not micro to mini)

 

http://www.ttvjaudio.com/mobile/Product.aspx?ProductCode=AAT0000200

 

Is there a reason that we can't find a good mini b (or better A) to micro B Elbow USB otg cable ?

Got my OTG cable today, plugged it in along with Dragonfly and the USB Audio Pro app (on GS4). Just had to restart the phone and voila! Pretty happy with this set up. smily_headphones1.gif

Samsung Galaxy S4 works, flawlessly plug and play, with the Devilsound Audio Cable.

To my surprise and delight, I might add :)

Yes there is... Outside a handful of head-fiers that want to connect USB DACs to their phones, there isn't a very big market for these kind of cables.

In most situations where people want to hook up external devices to their phone, the commonly available mini/micro USB to USB A receptacle cables suffice...

 

Also, positioning of USB ports on devices differs a lot, and with relatively short cables, that means a lot of stress on the cables if the connector needs to be rotated to the correct position, which would reduce durability. 

Your best bet is to have a custom cable made, suited to your combination of devices. Or you could make one yourself, it is not very difficult...

Wasn't able to get hold of the seller or even order.

Need that item at an extended length, about 1.5-1.7m then it will be perfect. =/

I guess that means we'll have to pay 5% service fees for an agent like this then

Other than yet, we could also ask some members in China for a little help.



For those of us with DIY skills, we could also get these right-angled connectors to make something and then sell them to other members who need one
