Well I got the Neutron player working with USB otg and the feature set is very nice. It seems to be doing something to the audio in 32 bit mode because it says 32 bit on the display and it doesn't pass "bit perfect" audio to my processor. I checked the settings but don't see a way to turn off this "feature". It doesn't seem to have the volume control problem like the Onkyo player.

I like the the approach of the new modular design of the LG 5. One can attach the new B&O DAC/headphone amp directly to the phone by removing the old bottom. Comes with it's own headphone jack independent from the top jack. Said to have the same Saber DAC chip and the newer Sabre amp from LG's previous V10.

Hi !
sorry to jump in.
I understand well that only Android Lollipop OS gives the possibility to use a compatible usb dac with all media apps like Kodi, VLC, Youtube and so on ?
I have bee using Usb Audio Player Pro app with an Android 4 device and it works very very well.
Not many dacs are compatible but when they are they sound excellent indeed.
But i need to use the external dac also with other media applications.
I wonder if one day there will be the possibility to load drivers like with any other OS.
Thanks a lot for the very interestin thread
bernardo

P.S. nobody using Kodi or VLC with an external dac ?

Hi and thanks for the helpful reply
I see that you use Android 6.0.1, So i guess this OS provides support for usb audio ?
This is the key point, because i have also USB Audio Player PRO (UAPP) but running on a Android 4 device and it indeed works fine for music.
But when i use Kodi i have to close USB Audio Player PRO (UAPP), of course, and the dac stops working,
For this i am about to try Lollipop that should have a native support of usb audio.
Hoping that Android 5 will recognize the dac of course.
So if i understand well the actual version of Android installed on the device is of paramount importance.

I am extremely interested in Android because i am surprised by how it can run on devices with very limited HW resources.
The traditional OS are too heavy and this in a way can impact the sound quality in particular.
I would hope that one day an Android version for pc will appear.
So that i could share it with all my devices. One OS for all systems. Complete integration.
Thanks a lot
Regards,
bernardo

Kodi, interfacing with the Android audio sub-system, is in the native USB audio world; UAPP in the third-party USB audio world.




In the native USB audio world, the USB audio source code developed by Google is more and less modified or not modified by the smartphone manufacturer.
Therefore, a given USB DAC can be compatible with the native USB audio of a given smartphone, and incompatible with the native USB audio of another smartphone.

A third-party USB audio developed by a given team is obviously different (i.e. different compatibility) than another third-party USB audio developed by another team.
And a third-party USB audio is obviously different than a native USB audio.

I found that the third-party USB audio soft driver included in USB Audio Player PRO (UAPP) is the most compatible.


Android USB audio - FAQ:
Enable USB audio on any Android 4.0 smartphone/tablet

How about compatibility of Android device with USB DAC?



At the present time, Android USB Audio is in its infancy.
But it is growing up: The FiiO E17 USB DAC/amp for example was not compatible with the first version of USB audio of the Samsung Galaxy S3. The E17 can now work with the S3.

It is not easy for the latest entrants (Samsung, Sony, HTC, LG, ..., third party USB audio developers, and now Google from Android 5.0 Lollipop) in the existing USB DAC jungle because the USB specification allows some variability.
http://www.head-fi.org/t/595071/andr...#post_10270550

The latest entrants have to adapt their USB audio implementation to (most) existing USB DACs.
They have to be compatible with different interpretations of the USB specification.

Once the native Google USB audio becomes mature, it will very likely become a reference USB audio implementation in the USB DAC industry used for testing by the developers of new USB DACs, i.e. these USB DAC developers will have to adopt the Google interpretation of the USB specification, because a "professional" USB DAC maker could not ignore Android, the biggest computing device market share.

The XMOS Multi-Function Audio Design Reference is used by many USB DAC makers to speed up the development of their USB DAC compatible with PC, Mac and Android; and the XMOS developers test it against PC, Mac and some key Android devices.

Hi and thanks a lot again for the valuable advice.
I think my only chance is to select a Lollipop device and try some usb dac.
As i said i have now a 4.X and when i run Kodi i have to shutdown UAPP. Cannot run the two apps at the same time.
Instead speaking only of audio i like the sound with UAPP very much indeed. Sounds very very good even better than my big pc (much more powerful).
At the point that i have reached the conclusion that OS and SW are more important than HW (for sound ... video is much more demanding in terms of resources. It needs powerful cpu and more ram and video card).

Thanks a lot again for the very interesting information.
In the meantime in the manual of the AQ Dragonfly i have found something interesting.

Quote:
To verify that your Android device complies with isochronous USB audio, download and run USB Host check:
https://play.google.com/store/apps/d...s.usbhostcheck.
For curiosity i run the app on my Android 4.2.1 phone and of course it does not have usb audio enabled.
Main problem is that testing a device for me implies buying it. I can only hope that it is enabled.
I see many media player extremely interesting and with Lollipop pre-installed. But i understand that the presence of Lollipop only is not a guarantee of usb audio enabled.
I will have to run the risk because the sound can be very very good ... when it works.
Thanks a lot again

Hey everybody, I want to connect my Galaxy S6 to speakers via USB and DAC, wondering what to get for best possible sound quality? I'm planning on going with PSB Alpha PS1 speakers, or maybe Audioengine A2 speakers. Or something similar for the speakers, basically in the $200-300 range. Any recommendations for a DAC? Will native android audio work or do I need the 3rd party app? Sorry if I'm resurrecting this thread, but didn't want to start a new one since this awesome one already exists!

Okay, so what does "best possible sound" mean to you?

How old are your ears? Will your source files be MP3 or lossless flac?

In my opinion, if your source files are only mp3, why not skip the expense of the DAC and use the headphone out direct direct from the phonel to the speakers (I may be incorrect in assuming the signal level will be ok from the headphone out to provide a useable signal for your speakers with this suggestion - others who KNOW rather than assume can comment here)

If on the other hand your source files are "best quality" lossless flac files, use the usb out (with an OTG usb cable, of course) to your choice of DAC (a quick re-read of all the above posts will give you some idea of best choice of DAC - I personally like my Oppo HA-2), then I would suggest the rca line out from DAC to speakers.

I suspect that (depending possibly on the version of android you are running) you will definitely need to use a third party player (again re-read posts above for choices - again, personally I have been exceptionally happy with the UAPP Pro app: it has succesfully played multi-channel 96/24 5.1 surround flac files and flawlessly mixed the 5.1 tracks down to 2 for headphones).

Depending on the DAC and speakers you choose, you may need a cable that has a 3.5mm rca on the dac end, and a split left/right rca plugs on the other (I think the Audioengine speakers gave you a choice, but not the PSB which I think will need the split left/right plug on one end).

Thanks for the reply. I'll be playing both mp3 and FLAC, so I would want to use a DAC to get the best out of the source files. I've heard of people having volume issues using just the 3.5mm jack and no DAC. But I wouldn't object to using the 3.5mm jack instead of usb, if it works. I read in a few previous posts that recent versions of android have native support for usb audio, so some have not needed the UAPP Pro app. But I can install it if necessary.

I have used UAPP for about 2 years, almost every day, works great for Flac files, including high bit and sample rates.

UAPP is great and very inexpensive.

Why not try it?
