    A stock Jelly Bean powered Nexus 7 should be able to interwork with an upcoming Android-specific USB audio out-capable USB DAC, like the Gear4 speaker dock, that acts a USB host (and the Nexus 7 as a USB peripheral).
    Gear4 speaker dock supports USB audio for Jelly Bean at Google I/O 2012 (hands-on video) -- Engadget

    Nexus 7 operating as a USB peripheral > digital audio stream >> Android-specific USB DAC "Gear4 speaker dock" operating as a USB host > Gear4 speaker dock’s amp > Gear4 speaker dock’s speakers

    Anyway, the Android-specific USB audio driver is included in the Jelly Bean kernel source code of the Nexus 7:
    [REF] All In One Nexus 7 Jelly Bean Android Development ! Sources,Roms,Kernels etc - xda-developers
    https://github.com/edoko/Air_Kernel_for_GN/blob/master/drivers/usb/gadget/f_audio_source.c#L2

    2 * Gadget Function Driver for USB audio source device
    4 * Copyright (C) 2012 Google, Inc.

    43 .bInterfaceClass = USB_CLASS_AUDIO,
    44 .bInterfaceSubClass = USB_SUBCLASS_AUDIOCONTROL,

    308 .bInterfaceClass = USB_CLASS_AUDIO,
    309 .bInterfaceSubClass = USB_SUBCLASS_AUDIOSTREAMING,



    The standard USB audio driver is also included in the Jelly Bean kernel source code of the Nexus 7:
    https://github.com/drewis/android_k...tegra3-grouper-3.1-jb-fr2/sound/usb/card.c#L2

    2 * (Tentative) USB Audio Driver for ALSA

    174 if ((altsd->bInterfaceClass != USB_CLASS_AUDIO &&
    175 altsd->bInterfaceClass != USB_CLASS_VENDOR_SPEC) ||
    176 altsd->bInterfaceSubClass != USB_SUBCLASS_AUDIOSTREAMING) {


    692 .bInterfaceClass = USB_CLASS_AUDIO,
    693 .bInterfaceSubClass = USB_SUBCLASS_AUDIOCONTROL }


    a standard USB audio-enabled Nexus 7 operating as a USB host > digital audio stream >> standard USB DAC like FiiO E7 or Objective DAC operating as a USB peripheral >> amp >> headphones


    It’s up to us to require Google & Android device manufacturers to enable standard USB audio!

    What about an app that enables this standard USB driver on rooted devices. Not the best, but a solution for now.
    Google Nexus 7 Tablet (Tegra 3)

    Instructions of Tsynik, who has successfully enabled the standard USB audio feature on some Android-powered tablets:
    USB audio cards support (drivers and libs) - SlateDroid.com
    "There are no special code for support USB sound devices in Android itself. It's all in Hardware Abstraction Layer, so it's always device specific.

    We just need 3 base things:
    1st: USB Host support in Android kernel.
    2nd. USB audio driver, in kernel, or compiled as a module.
    3rd. Some logic to switch to USB audio card, or back to internal one. So, it can be checkbox in Android preferences, or automatic switching via init.rc and it's on-device-added events. Last thing is your choise, you can set it in many ways (as it's controlled by property change, or, on other devices, by asound.conf rules), but it's not universal yet."

    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"
    Wolfson DAC confirmed for Galaxy S3!

    "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:
    [DER KERNEL] Trinity Seven - Page 44 - xda-developers
    Instructions for connecting USB DAC to Touch


    "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."
    xda-developers - View Single Post - [DER KERNEL] Trinity Seven


    "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."

    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.
