If you want the USB audio enabled on any Android 4.0 device via official firmware/kernel, please vote (aka star) here:

According to Android 3.1 specifications, Android 4.0 devices could support the USB audio feature, i.e. Android 4.0 devices and USB_CLASS_AUDIO compliant devices like standard USB DAC could interoperate:
http://developer.android.com/guide/topics/usb/index.html (http://developer.android.com/guide/topics/usb/index.html)
http://developer.android.com/reference/and...bConstants.html (http://developer.android.com/reference/android/hardware/usb/UsbConstants.html)
USB_CLASS_AUDIO compliant devices like standard USB DAC don’t need a special USB device driver. Instead, they use an operating system standard driver.
The Android standard USB audio driver is the generic USB Audio Driver for ALSA (Advanced Linux Sound Architecture).
And the latest Android 4.0 includes “card.c“, the USB Audio Driver for ALSA which should be compliant with USB audio class 2 devices allowing for 24 bits / 192 kHz.
https://bitbucket.org/paulobrien/android_ke...ound/usb/card.c (https://bitbucket.org/paulobrien/android_kernel_galaxynexus/src/bc4f9b72a51d/sound/usb/card.c)
(http://farm6.static.flickr.com/5253/5534201226_7e7d2d90eb_b.jpg)
Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model. The Linux kernel also acts as an abstraction layer between the hardware and the rest of the software stack.
Thus Android handles all the things that Linux is really good at such as a vast array of device drivers, which take the pain out of interfacing to peripheral hardware.
The official Android with USB audio enabled should be used by most people, who don’t want to mod their device.
A die-hard audiophile minority should likely use audio-optimized Android kernels modded by some kernel modders.
"An interesting example is the HRT music streamer II, it IS asynchronous USB, but it is still very sensitive to what happens in the computer. On the SAME COMPUTER I can make simple changes to OS scheduling parameters and get a huge difference in the sound. At one end of the scale it’s dull, lifeless, no depth at all, at the other end of the scale it is wonderfully alive, dynamic, huge depth etc. And all this by just changing a few numbers, NO change in hardware at all."

For example, an underclocked kernel should be better than a normal kernel to provide a lesser jittered digital audio stream to a USB DAC, because the USB transmission clock is less polluted by electric and electromagnetic interferences generated by different processors.
Android kernel modders have already enabled the USB audio feature on Nook Color tablets which are powered by Android 2.3 Gingerbread.

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 FiiO E7, the iBasso D12, Leckerton UHA-6S MKII, the ODAC and the VentureCraft Go-Dap X; has some issue with the HeadAmp Pico; and doesn’t work with the FiiO E17.
So, in regard to standard USB audio, the behaviour of the Galaxy Note II is likely identical to the behaviour of the Galaxy SIII.

"Now that I've had these for a good month I can honestly say they are my 'New' daily headphones!
I simple love the music that comes from these headphones.
They are beautifully balanced with sparkly highs that are not offensive to the ears, mid's that introduces a 'fun' factor to the music for all genres and lastly lows that are firm, bassy and goes amazingly deep with out distorting or overpowering the rest of the music.
The clarity is excellent with a very nice sound stage and for a 'closed' headphone they do sound quite open and spacious!
Isolation is fantastic especially listening to music or playing games at night.
Comfort is excellent and the 'killer' clamp grip slowly eases after regular use! I've listened to these all night and in to the early morning without wanting to take them off!"

A die-hard audiophile minority should likely use audio-optimized Android kernels modded by some kernel modders.
"An interesting example is the HRT music streamer II, it IS asynchronous USB, but it is still very sensitive to what happens in the computer. On the SAME COMPUTER I can make simple changes to OS scheduling parameters and get a huge difference in the sound. At one end of the scale it’s dull, lifeless, no depth at all, at the other end of the scale it is wonderfully alive, dynamic, huge depth etc. And all this by just changing a few numbers, NO change in hardware at all."
http://www.audioasylum.com/cgi/m.pl?forum=pcaudio&n=101397 (http://www.audioasylum.com/cgi/m.pl?forum=pcaudio&n=101397)
For example, an underclocked kernel should be better than a normal kernel to provide a lesser jittered digital audio stream to a USB DAC, because the USB transmission clock is less polluted by electric and electromagnetic interferences generated by different processors.
I got excited when I read this part, it sounds like it would be possible to tweak a few settings (I assume with sysctl) in order to gain sound quality.
Sadly, though, I found this:
You can track it down if you want the details . . .
And I miserably fail to "track it down". Why is it that people are not willing to provide useful links in their posts, but send forum members away with "If you really really want to, you find it somewhere"

MediaTek, a fabless semiconductor company, supplying chipsets to major Indian and Chinese handset manufactures to run Android operating system, has announced the availability of its third generation platform (chipset) - the MT6575, for mid and entry level Android smartphones.
Phones based on this new platform will be available in the Indian market from April onwards.
As a result of this development even low lost Android handsets, which come in the price bracket of Rs 5,000 to Rs 10,000 will be able to run Android 4.0 or Ice Cream Sandwich. It is not possible to do so in current low cost Android phones as the minimum system requirement is not met and even if it does meet it, performance is not up to the mark. The MT6575 platform offers a 1 GHz ARM CortexTM A9 processer, a 3G/HSPA+">HSPA modem and it runs the latest Ice Cream Sandwich Android 4.0 smoothly, according to a release from MediaTek. :duh: :duh: :thumb: :green: :icon_lol:

The USB DAC recommended by Google is a new type of device. It is not compatible with PC or Mac.

A legacy USB DAC compatible with PC / Mac acts as a USB device, and a PC / Mac acts as a USB host.
A USB DAC recommended by Google acts as a USB host, and a Android smartphone / tablet acts as a USB device.
Personally, I prefer the legacy USB audio feature implemented by Samsung on Galaxy S III, which can interwork with a legacy USB DAC like FiiO E7 or ODAC.
The legacy USB audio feature is still specified in the Android specs:

An Android 4.1 Jelly Bean-powered device can have both USB audio out modes: standard USB audio out and Android-specific USB audio out.
These features are at the Android kernel level.
http://developer.android.com/tools/adk/aoa...l#audio-support (http://developer.android.com/tools/adk/aoa2.html#audio-support)
"Android Open Accessory Protocol 2.0 includes optional support for audio output from an Android device to an accessory. This version of the protocol supports a standard USB audio class interface that is capable of 2 channel 16-bit PCM audio with a bit rate of 44100 Khz. AOA 2.0 is currently limited to this output mode, but additional audio modes may be added in the future.
To enable the audio support, the accessory must send a new USB control request: SET_AUDIO_MODE"

It should be easy to enable standard USB audio out and Android-specific USB audio out on an Android 4.1 Jelly Bean-powered device with USB host capability.
Let's keep up the pressure on Google and the Android device manufacturers for the standard USB audio out:

I got excited when I read this part, it sounds like it would be possible to tweak a few settings (I assume with sysctl) in order to gain sound quality.
Sadly, though, I found this:
You can track it down if you want the details . . .
And I miserably fail to "track it down". Why is it that people are not willing to provide useful links in their posts, but send forum members away with "If you really really want to, you find it somewhere"
I think this is it, after step 7 http://www.cicsmemoryplayer.com/index.php?n=CMP.10Soundcard (http://www.cicsmemoryplayer.com/index.php?n=CMP.10Soundcard)

The combo "Odac + Neco V3" is very well-praised:

"ODAC + NECO V.3 + Sennheiser HD580 = A MATCH MADE IN HEAVEN.
I can't tell you how beautiful this rig sounds. We all know how well the HD580/600 scales with better sources and amps.. but synergy is often undervalued. The ODAC is beautifully resolving and clean.. but the Neco really steals the show, IMO.
My V.3 has the 8610s & lithium battery.. and boy, does the HD580 love it. A DEAD silent background, fantastic dynamic range.. and the artful Sennheiser sound.. on steroids! Treble has spectacular air, crispness, and detail.. the mids are very very transparent and deep.. with the bass coming tight and punchy. One thing I've really noticed the Senn benefits from is the V.3's dual opamp setup.. which provide fantastic channel separation, imaging, and soundstage. It's so immersive.. I can listen to this setup for hours on end. I like this little combo more than my desktop rig (via the tube or SS output!) and the ODAC+O2 (which is a little too clinical). For those one the fence about this amp.. stop waffling.. it's a GEM.
I also dropped the gain jumpers in so I've got it set at low gain (2.3x) since it's being used with the ODAC (2 Vrms output). the Neco it quite ably drives the HE-500, btw. Very clean & dynamic, again.
When driving the HE-500.. I like this combo more than the O2."
The Odac USB DAC can interwork with an Android powered smartphone Samsung Galaxy S III as well as with a PC or a Mac.

As expected, for the time being the Nexus 7 doesn't interwork with standard USB DAC like FiiO E7 or FiiO E17:
http://www.head-fi.org/t/616125/google-nexus-7-tablet-tegra-3/45#post_8525225
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).

Ok in the first post in this thread there is mention of John Swensons....results of mucking around with OS scheduling parameters??? Does anyone have any more details here?? Like what OS, what settings or parms that allow gor bit perfect playback with NO OS interferance over USB...?????
""An interesting example is the HRT music streamerII, it IS asynchronous USB, but it is still very sensitive to what happens in the computer. On the SAME COMPUTER I can make simple changes to OS scheduling parameters and get a huge difference in the sound. At one end of the scale its dull, lifeless, no depth at all, at the other end of the scale it is wonderfully alive, dynamic, huge depth etc. And all this by just changing a few numbers, NO change in hardware at all. ""
All the best

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.

"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"

"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."

"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."

"If a serious headphone-loving audiophile encountered the E7 with no brand name they might easily suspect a stealthy black Apple product. It’s similarly sexy, solid, and hewn largely from black anodized aluminum with impressive tolerances and finishes—much like an iPhone 4. "

"Designed specifically for Android devices

Drives headphones directly with 3.5mm mini-jack output
Fixed or Variable output modes
Asynchronous transfer for accurate digital timing

I am wondering if the AudioQuest Bumblebee Android DAC is a standard self-powered USB DAC or an Android-specific USB DAC.

The AudioQuest Bumblebee should be likely an AudioQuest DragonFly with built-in rechargeable battery, because it "supports all music files including 24-bit/192kHz lossless".
http://www.head-fi.org/t/617241/audioquest-dragonfly-review-affordable-outstanding-tiny-dac-amp (http://www.head-fi.org/t/617241/audioquest-dragonfly-review-affordable-outstanding-tiny-dac-amp)
http://www.stereophile.com/content/audioquest-dragonfly-usb-da-converter (http://www.stereophile.com/content/audioquest-dragonfly-usb-da-converter)
And an Android-specific USB DAC can support only 16-bit/44.1kHz:
http://developer.android.com/tools/adk/aoa2.html#audio-support (http://developer.android.com/tools/adk/aoa2.html#audio-support)
If the AudioQuest Bumblebee is a standard USB DAC, while using with a PC or a Mac, the sound quality of the AudioQuest Bumblebee should be superior to the sound quality of the AudioQuest DragonFly thanks to a clean battery power.

I picked up a Motorola Xoom that I need to upgrade to Jelly Bean. Has anyone ever tried the USB out on this tablet? I've posted a similar question on the Xoom forum yesterday with no responses thus far. Is there any danger with me hooking up the Xoom to a Bryston BDA-1 USB input? I'd hate to damage either unit.

Do you turn off the wi-fi and cell phone part of phone? If I have my phone anywhere within a foot of the wires for my headphones, I get horrible cross-feed into the headphones if the cell phone part of the phone is on.

Well, I discovered today that my Archos 80 G9 does in fact work with my ODAC/O2 rig. I had read that the G9 was supposed to be able to support it, but I tried it earlier with no luck. Today I found myself considering an iPad mini for playback and figured that a 32G micro-sd card was probably cheaper :-), so I inserted a powered USB hub into the chain and playback works fine. I thought that since the ODAC/O2 combo unit has a power adapter that the USB circuit would be internally powered, but apparently now.
Now to get some flac files onto it and see how well it works.

It’s weird that a phone like the Samsung Galaxy S III / Galaxy Note II can supply enough power for the ODAC or a HeadAmp Pico, and a tablet doesn’t have enough power for that.
“While it's not a phone, my Exynos powered Galaxy Note 10.1 tablet works with both my HifiMan HM-601 and HM-801 with no problems, settings changes, tweaks, or anything.
My HeadAmp Pico and Pico DAC both require a powered USB cable or hub to work, or I get the High Powered USB error.”

Nope.
I have no issue with a Galaxy S III, an ODAC (Epiphany Acoustics E-DAC), Soundlab Neco V3 amp and Fischer Audio FA-003 headphones.

About Android-specific USB audio:
"As of now, the standard Android releases do not include USB host support. Samsung decided to add this feature on their own. The Android folks are working on a funky USB dock protocol that works over USB (sort of like what Apple does) that, frankly, most of us developers think is stupid. There is certainly a push to put USB host support for standard devices (like audio, keyboards, etc.) into the normal Android releases."

The us$43 Samsung Galaxy S3 + Car Stereo Upgrade for WAaaY better sound quality!
http://www.head-fi.org/t/639883/the-43-gal...r-sound-quality (http://www.head-fi.org/t/639883/the-43-galaxy-s3-car-stereo-upgrade-for-waaay-better-sound-quality)
Galaxy S3 > digital USB audio out >> "USB OTG" cable >> Behringer UCA202 USB DAC >> car stereo amp >> car stereo speakers
"...
And so what are the results you ask?
HOLY MOLY!
Not only is the audio quality MUCH improved, but the sound is so CLEAN now. No clicks, burps, or any other weird background noises. Just straight CD quality background silence.
Even my GPS voice sounds prettier. hahah
Bass is tighter and deeper. Highs are more revealing. Everything is so much better that a novice could tell it sounds better.
And yes, GPS navigation works perfectly. If I'm listening to Pandora or an MP3 and my GPS needs to talk, then my music will go several db quieter and GPS will speak up, then afterwards the music will automatically go back to full volume.
Also, one thing I hated about Bluetooth was everytime I turned my car off for just a minute, when I would power it back on the Bluetooth would not consistently reconnect. Well, this USB-OTG has been very consistent for me so far. Music just picks back up where it left off at and is fairly quick to do so.
Cons? Well, I haven't tested hands free calling yet. But I'm told it doesn't work with this USB-OTG to DAC configuration. Maybe there is a bluetooth solution for that. I dunno? And AOSP does not yet support DACs.
Pros? Freakin everything.
Pics are below.
Here is the DAC and the USB-OTG cable:
(http://www.avsforum.com/content/type/61/id/103020/width/500/height/1000/flags/LL.jpg)
This is how you configure the DAC.
You can probably also use the headphones output instead of the stereo RCA, but I didn't try it.
(http://www.head-fi.org/content/type/61/id/734842/width/500/height/1000/flags/LL.jpg)
I wired up my USB-OTG cable to my iBOLT dock. It comes up through my dash defrost vents.
(http://www.avsforum.com/content/type/61/id/103025/width/500/height/1000/flags/LL.jpg)
This is what the three connectors on the USB-OTG cable look like:
(http://www.avsforum.com/content/type/61/id/103026/width/500/height/1000/flags/LL.jpg)
Here is the DAC being wired up. I taped up the non-used RCA's to prevent anything bugging with them.
(http://www.avsforum.com/content/type/61/id/103027/width/500/height/1000/flags/LL.jpg)
I wrapped up the DAC with DUCT tape.
Not sure how or why the pic is sideways. It looks normal on my desktop.
(http://www.avsforum.com/content/type/61/id/103028/width/500/height/1000/flags/LL.jpg)
Hid it behind my dash.

Here is the USB-OTG cable with my iBOLT dock.
(http://www.avsforum.com/content/type/61/id/103032/width/500/height/1000/flags/LL.jpg)
The car stereo w/audio cable attached. Some car stereos have the 3.5mm connector in the back. Or a dual-RCA input. I'd prefer one of those to have a cleaner install. Maybe someday I'll upgrade my car stereo.
(http://www.avsforum.com/content/type/61/id/103033/width/500/height/1000/flags/LL.jpg)
And here is the finished product. My S3 docked, charging and outputing beautiful digital music!
