Nope, for the time being.

Another app from the same developer, USB Audio Recorder PRO also including its own USB audio soft driver, can play music files stored on a 2TB external USB hard drive (USB hard drive and Android device connected to a powered USB hub).
http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/4545#post_10473524

By the way, USB Audio Player PRO & USB Audio Recorder PRO can play and output 24-bit high resolution audio to a 24-bit capable USB DAC.

That means the usb audio driver only works via those apps?

I think this is a limitation, considering that there is some apps which can access my files on the NAS normally.

Yes, the USB audio soft driver of USB Audio Player PRO (UAPP) / USB Audio Recorder PRO (UARP) can only work with UAPP/UARP for the time being.
The UAPP/UARP developer has unsuccessfully convinced other music player app developers to use his proprietary interface.




The UAPP app is relatively new. The UAPP/UARP developer is asking for a lot of requirements like folder playback.
Your requirement of DLNA/UPnP support should be posted on the thread "Android phones and USB DACs": the UAPP/UARP developer used to read it.
http://www.head-fi.org/forums/posts/by_user/id/351770

In the meantime, my workaround with a Galaxy Note 3 having a native USB audio feature is the following:
. using BubbleUPnP to discover new music stored on my NAS
. using UAPP for the best sound quality to listen my preferred music stored on a 64GB microSD card (waiting for a 128GB microSD card).

Hi, lots of great information here.

 

I have an old car (68 Chevelle) which currently has no audio system at all.  I'd like to build a head unit using something like a Samsung Galaxy Tab 3.  It seems like post #83 is most relevant to my project, but wanted to check since it was posted a while back, and things change fast.  My thinking was that I would install a standard car amp, then use the DAC and cables mentioned in post #83 to go: Tablet -> DAC -> Amp -> Car speakers

I haven't bought any gear yet, so I can adjust my plans if needed.

 

my questions are:

- will I need to use a specific audio player on the tablet, or will any player work?

- I like that the Behringer UCA202 is so economical, is it still the best option in this price range?

- Will I need to root my tablet?

- Anything else I need to be aware of ?

Thanks, Jon

It depends.

If your Android device has only a USB host feature (i.e. USB host-enabled Android device), only UAPP/UARP can drive a USB DAC. Most Android devices like the $40 Azpen A70 have a native USB host feature.
http://www.avsforum.com/t/1393599/enable-usb-audio-on-any-android-4-0-smartphone-tablet/180#post_23970959

If your Android device has a native USB audio feature (i.e. USB audio-enabled Android device), any player including UAPP/UARP can output a digital USB audio stream to a compatible USB DAC.

There is a list of stock Android devices reportedly working with compatible USB DAC on the fist post of this thread:
http://www.avsforum.com/t/1393599/enable-usb-audio-on-any-android-4-0-smartphone-tablet

Not exactly an app music player, actually through the "ES File Explorer" (https://play.google.com/store/apps/details?id=com.estrongs.android.pop.cupcake) I can access my NAS on the Windows Lan and play the most common media files, eg. MP3, FLAC, etc.

ES File Explorer is a file browser which can access (music) files stored on a remote PC.




Clicking on a music file will trigger a menu of installed music players (USB Audio Player PRO, ...) to be selected: the issue is only one music file can be played at a time (i.e. no random or next song playback mode available).

OK, I think that I have to wait for an app which could do everything that I need.

Thanks again, DanBa!

A list of USB OTG cables:
http://goo.gl/4JyOe5

http://www.avsforum.com/t/1393599/enable-usb-audio-on-any-android-4-0-smartphone-tablet#post_21633143


Android device >> USB OTG adapter cable + regular USB cable usually provided by the USB DAC maker (i.e. standard USB plug to standard / mini / micro USB plug cable) >> USB DAC >> amp >> headphones


Each component of the Android rig should be separately tested:

1. Test the USB DAC with a PC or a Mac:

PC >> regular USB cable provided by the USB DAC maker >> USB DAC >> amp >> headphones

2. Test the Android device with a USB OTG adapter cable and a simpler USB peripheral like a USB mouse or a USB keyboard:

Android device >> USB OTG adapter cable >> USB mouse

3. Finally, test the setup with a USB OTG adapter cable:

Android device >> USB OTG adapter cable + regular USB cable >> USB DAC >> amp >> headphones

If the final test is unsuccessful, then this Android device doesn't have a native USB audio feature, or the native USB audio feature is not compatible with this USB DAC (i.e. developers don't have the same understanding of some part of the USB specification): the USB Audio Player PRO app which includes its own USB audio soft-driver could be used to fix this interworking issue.
If the USB Audio Player PRO music player is not compatible with this USB DAC, then Davy Wentzler, the developer of USB Audio Player PRO, should be contacted.

Anyway, the USB audio soft driver of USB Audio Player PRO can drive a Chord Hugo USB DAC/amp.

XMOS Multi-Function Audio Design Reference:
. speed up the development of a USB DAC compatible with Android, PC and Mac
. tested against Samsung Galaxy S3 / S4 / Note[3], Sony Xperia Z1, HTC One.
https://www.xmos.com/support/downloads/xkits/Reference%20Designs?product=17498

The XMOS people should also test their XMOS Multi-Function Audio Design Reference against the USB audio soft driver of USB Audio Player PRO, anyway very likely compatible.

USB Audio Player PRO is capable of folder playback.



I like the possibility to play files:

. not recognized as "audio" by Android like mp4 video files

. stored on a folder on a (2TB) USB drive continuously in shuffle mode: USB DAC and 2TB USB drive connected to a Galaxy Note 3 via a battery-powered USB hub.

I now have the Hugo

It works fine but I have to use USB Audio Player PRO as the player..

hope they enhance this player - it is Ok but not as good as others

however I am grateful that the player exists - the HUGO really is impressive!

I had been using USB Audio on my Xperia Z for at least a year, worked with any media player, finally settled on the inbuilt Sony Walkman with a FiiO E17/FiiO E18 and AKG Q701/AKG K550 headphones. Suddenly it stopped working, I'd get three seconds of music then silence accompanied by the "USB using too much power" message. Everything worked perfectly with the AKG K550's but not with the Q701's. Trawled through every solution online but was still stumped. The only thing I had changed was headphone cable for the Q701's - so in desperation switched back to the previos cable et voila! Everything worked perfectly again! The new cable was the same brand as the previous cable, just shorter. So, if anybody has an issue - try swapping headphone cable over!!

 Have to say, listening to early Cure stuff on an Xperia with "surround sound" enabled, hooked up to the E17 or E18 and the Q701's is like hearing the albums new all over again! I do prefer the E17 to the E18, looks better and is more sturdier, I think it gives better sound also. Vinyl ripped to 24Bit FLAC is just gorgeous ..........

I wanted to ask if it was indeed true that the Audioquest Dragonfly v 1.0 is capable of being used as a dac with the Samsung s3 with an otg to micro usb? I believe I saw one connected otg cable, so I am on the edge of grabbing one or the HRT Music Streamer which I can get either one for 100$ or under for the MS II. I know there is the AMB Gamma 1 Lite which I am hoping that I can use with my S3 phone. any one had any luck with that diy DAC

How does the Fiio e17 sound as far as a dac is concerned? I can get one currently at 80ish USD. I am going to be using it with my phone, but I could also get the Dragonfly for a 100$ and the HRT MS II for 90. I am at a loss. I hater not being able to try these out.

Yes with USB Audio Player PRO according to the list of compatibility at the bottom of the 1st post.

For more details like headphones matching / synergy, you should ask the owner of the DragonFly who posted the Galaxy S3 - DragonFly compatibility information.

I like it a lot, makes  a massive difference to audio clarity, treble in particular. Also has an 'Optical Line' in which comes in handy. I have a FiiO e7 DAC you can have for the price of postage if you want to experiment with that?

Yeah I ended up not being able to get any of the ones I wanted to do to a ear infection medicine cost for my kid, and on top it htey put me on new meds that is not covered by my insurance which was ridiculous. 3 months of being out of work with a clot has seriously put a depressing cloud over my life currently. I jsut wish my luck would change for just a day.

I suppose not every single USB DAC out here will be supported tho, as not all of them behave the same despite following the same spec (this includes power requirements).
I'll keep in mind the idea of maintaining a compatibility list." [Supercurio]

Well-praised review of "Resonessence Herus + Dell Venue 7 / HTC One + USB Audio Player PRO (UAPP)":
http://everythingaudionetwork.blogsp...-heru-dac.html

"... audiophile playback ... the sound quality via the tablet was as good through the Herus as the Macbook Pro and Audirvana playback, Clean, quiet, smooth and plenty of detail, especially for the money...."
