T-Mobile Galaxy Note 3 working natively using the Tweaked 3.8 rom and iFi iDSD Nano!
 
I tested YouTube, default music player, PowerAmp and one video game, Another World. All worked!!

I used the Effortless Guide to install stock NF9, but instead of TWRP 2.8.0.0, I used 2.7.2.0. At the point where it suggests the Effortless Rom, I simply used Tweaked 3.8. I used the super simple approach listed in the Tweaked 3.8 install instructions.

HighRes audio support via USB is a very good news (no need for USBAPP...!!).  
 
With a 128 Gb MicroSD, we finaly have a decent source for our portable DACs (HUGO...)
 
But I wonder if the Z3 compact tablet (8") also has this HighRes audio support via USB ?  I can't see it on it's specs !

Hello guys, can you recommend some powered usb hub that could work with a dac on android? To charge my smartphone and at th same time use the dac?

Quick question - Just installed poweramp trial on my Moto X and using OTG with HRT Microstreamer.  While listening to some Bela Fleck and Edgar Meyer got BLASTED by a tone notifying me of a text.  Other than turning notifications and ring tone volume all the way down on the phone, is there any other way to set a preference for no other system sounds while listening to music?  Either in Android or the player?
 
thanks for any help.

To my happiness the dac was delivered today with my vivo xe800, now dac hifmediy sabre android + amp nx1 topping + vivo xe800 = wonderful thing!

I continue to work with it, I am getting prepared for the day my wolfson Note2 bites the dust and I have to replace with an inferior sounding device. The iphone is a great piece of gear but I like modding too much to leave android. So my idea was to try aptx with a good dac amp combo. Most of my listening is mobile on the run and need a integrated microphone as well.

Although high resolution playback is still not enabled natively on Android on the current implementation of USB audio, hopefully that tablet have thanks to Sony writing their own driver. That would be very cool.

The current Android media player framework can only output 16/48, and Sony has modified it so that it can output high-res audio to the internal DAC as well as to a USB DAC.

There are no changes in Android 4.4 which improves USB Audio, and Google has not gone public on any such improvements in the future. Basically, it is up to chip suppliers and OEM's to do such changes, which is difficult since the whole Android framework is buiot upon resampling into 48kHz/16 bits.

However, Sony Mobile presented two new products yesterday, the Xperia Z2 phone and T2 tablet, which offers high-res audio over USB, through what we call "Direct mode". Basically we completely bypass the audio framework and send the decoded audio data directly to the USB driver without any processing or any mix-in of notifications, ring signals, et c. We also replace the USB driver and the FLAC decoder, to support 192kHz and asynchronous USB Audio Class 2. The only thing we change in the data stream is that we pad 16 bits to 24 and 24 bits to 32 when required by the DAC. Together this gives us the ability to support replay of FLAC and WAV at any sample rate from 44.1 to 192kHz at either 16 or 24 bits.

This is part of the overall Sony High-Res initiative, by which we want to bring back the excitement of high quality music reproduction and leave hard-compressed MP3 behind us.

As product owner for this feature I will be available in this forum to try to answer your questions and note any criticism we can use to improve our products.

  The "Direct" output to USB should work with all media players which are using the "Player" component in the Android framework for music playback (basically, what this component does is opening a particular file upon request by the player app, and sending it to rest of the framework; when our high-res is activated, this file is unpacked/decompressend and is then routed directly to the USB driver). I am right now listening to a 88.2kHz file using Google Music, and the DragonFly glows in amber which is the 88.2 kHz indicator.
 
I am sorry that I cannot publish any screen shots yet, the software is still not finalized.
 
We currently support FLAC and WAV up to 192kHz. MP3 and AAC are supported at their native sample rates before compression (44.1 or 48kHz). ALAC is not currently supported. I have requested ALAC support, but it has been down-prioritized (and I cannot comment on future products or product updates). If you have ALAC files, you can use XRecode or similar programs to quickly convert between lossless formats without any impact.
 
Other formats generally supported by Android should work, at those sample rates supported by our chip supplier, but has not been in the scope of this feature and have not been verified - we have focused on formats generally available for high-res downloads.
 
The available user memory is approximately 12 GB out of the box; this memory is shared with downloaded apps and their data (the rest of the 16GB is reserved for Android and preloaded apps, etc). The SD card slot has been verified for up to 64GB; I hope we will soon be able to verify the new 128GB cards from SanDisk.
 
I am not sure if can state that we officially "support" this, but for me it works to use a small portable router between the USB OTG cable and the DAC. You can then connect a USB stick and play tracks from that. I will discuss with the product team if this voids your warranty or not....

Apparently, the Xperia Z3 Tablet Compact supports hi-res USB audio : the Xperia Z3's Audio Settings page in English seems be similar to the Xperia Z3 Tablet Compact's Audio Settings page in Chinese.
Hopefully, a chinese spoken headfier will confirm it.

Hello guys, can you recommend some powered usb hub that could work with a dac on android? To charge my smartphone and at th same time use the dac?

 
Theoretically, when an Android device acts as a USB host working with a USB DAC, it is not powered by a powered USB hub: Android device connected to the upstream port of the hub, USB DAC connected to a downstream port.
(Some non-compliant powered USB hubs can power the USB host via the upstream port: is it damage-free?)
 
When the Android device is not used for listening music, it can be powered by a powered USB hub: Android device, acting as a USB peripheral, connected to a downstream port.
 

 
 
A USB OTG/ACA-Y cable can allow an Android device to interwork with a standard USB DAC while charging.
http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/2580#post_9598490
 

 

 
A USB OTG/ACA-featured Android device can be configured to USB host mode drawing power from an external power supply by ACA/OTG software/hardware measuring the value of the ID resistor of the USB interface.
 
For the time being, (some) Android device manufacturers don't use the value of the ID resistor specified in the USB ACA specification.
 
Hopefully Google will support ACA: it should encourage the mass production of USB OTG/ACA components, and prevent Android device manufacturers from implementing non-standard ACA.

thanks for any help.

I usually toggle off the sound, or go to airplane mode if I really don't want to be disturbed.  I notice that some roms rout notification sounds to USB, others keep them on the speaker.

In order to have a clear understanding of the problem, I think you should focus on testing your setup with UAPP because:
1. the USB audio soft driver is reputedly the best USB audio implementation (more precisely better than the Galaxy S5's native USB audio feature used by other music players like Spotify or stock music player of the S5)
 

 
2. UAPP doesn't perform any resampling:
16/44.1 music file > S5 using UAPP > 16/44.1 PCM stream >> DragonFly >> headphones
24/96 music file > S5 using UAPP > 24/96 PCM stream >> DragonFly >> headphones

3. the UAPP developer can be contacted.
 
"Make sure to connect your audio device [DragonFly] BEFORE starting USB Audio Player PRO." (Connecting the USB DAC to the Android device will trigger the activation of the USB host driver, then attached/used by the USB audio soft driver of UAPP).

 
Thank you for your help. I did real life testing, which did take some time, since I do not only listen to my smartphone... I can live with the residual problems and send you the following comments as a feed-back.
 
The unpredictability of the connection of the Dragonfly to the Galaxy S5 persists but it is less annoying than described in my first post. The connection can be o.k. from the start with any app but sometimes fails, even with UAPP. The chances it works from the start are highest with UAPP as you predicted and if it fails with another app I now build up the connection with UAPP and then go back to the app I really want to use.
 
In my first attemps to solve the problem I actually connected the DAC before starting any application, as you told me to do, so I always had to close it or even to restart the smartphone if the connection did not work. This was very cumbersome. In this second series of tests, I mostly stayed in the application (say, UAPP), diconnected the DAC, restarted the stream and reconnected the DAC. It did not work always at the first attempt but very often. So the correction procedure is much lighter now than in the first series of tests.
 
I have tested another Dragonfly 1.2 the same way with identical results.
 
Both Dragonflies persist to show a magenta fly (96 kHz) when plugged into the smartphone (also with UAPP playing FLACs ripped from CDs or 128 kbs podcasts), although they 'can green' (44.1) when sticked to a worstation, which has been parametrized for 44.1 kHz output.
