It shall be done in the next step like the enabling of standard USB audio on the Linux-powered Squeezebox Touch.
Android 4.x includes the ALSA source code which can be compliant with USB audio class 2 devices allowing for 24 bits / 192 kHz:
https://bitbucket.org/paulobrien/androi ... ard.c#cl-2

The USB audio is enabled manually on Squeezebox Touch in the first step:

The latest method uses an applet which allows a custom kernel to be installed and provides menus to select the audio output device.
This custom kernel can also support 24-bit/192KHz USB DACs.

So far, like the quad-core Exynos powered Galaxy S III, the new quad-core Exynos powered Samsung Galaxy Note II can work with the iBasso D12 and the ODAC, and has some issue with the HeadAmp Pico.

So, in regard to standard USB audio, the behaviour of the Galaxy Note II is likely identical to the behaviour of the Galaxy SIII.

Apparently "Galaxy S III + (some) USB DAC" and "(some) computer + (some) USB DAC" have at least the same sound quality:

"How about the SQ of the S3 + NuForce Icon HDP? What headphones do you use?"

"It's quite good. Slightly, not very noticeable, better than it was connected to my computer.
So if you wanna know more about this, you can just simply refer to those review of HDP.
P.S. I am using HD600 & UM1 for testing"
http://www.head-fi.org/t/608535/wolfson ... st_8571797

"For anyone interested, the D12 USB DAC works when connected to a Galaxy S3. It sounds the same to me as it does when connected to a computer."

A custom Nexus 7 interworks with a standard USB DAC FiiO E10 (that doesn’t work with stock Samsung Galaxy S III for the time being):

custom Nexus 7 > digital audio stream >> USB DAC/amp FiiO E10 >> Sennheiser HD-380

Instructions for customizing a Nexus 7:
http://forum.xda-developers.com/showthr ... st29805237
http://forums.slimdevices.com/showthrea ... light=Udev

"Code:
pcm.usbdac {
type hw;
card Audio;
}
ctl.usbdac {
type hw;
card Audio;
}
pcm.!default usbdac

Back up your asound.conf and add this (or for simplicity sake, replace it with this)

This allows me to use my Nexus 7 to play over my Fiio E10 USB DAC, N7 + E10 + HD380 == fun.


It's too late for me to work on combining this with the stock asound.conf.

It's in /etc/ on stock rom and works once replaced."

"We are lucky, no such file or luck on GN or SGS3 yet, need to first understand how alsa works on those phones.

Yes, double check you need the alteration.
I never got sounds out the USB DAC without it.
And now with it, plays fine with DAC, but also when DAC is not plugged, plays sounds as if I never changed anything.
Which is nice either way, not needing to change the file all the time.
Need to find out if/how I can modify the default device for np and sgs3 now, they neither had nor sorry the file.
No support meaning adding the file doesn't change anything there."

I haven't quite read through all of this thread closely, but having recently purchased a Galaxy S III it is of interest.

However, I don't really understand why having my phone connected to my dac/headphone amp if possible (Audio-gd NFB 5.2)/Beyer DT 990 (250 Ohms) would be definitively superior to listening via my laptop?

I could understand if many of the rigs were truly portable, but most that I see mentioned above definitely are not, though I'd need to go back over the thread to check all those mentioned.

Do you really believe that Neutron via Galaxy S III via a quality dac will give superior results to computer w/dac?

Cheers!

BTW....I do love Neutron, but hadn't considered it would give superior results in such a way.
