USB audio is enabled on Texas Instruments Blaze tablet, which is targeted at developers.

"The two HS USB ports are the standard High Speed Host ports and are used for connecting devices like Mouse, Keyboard, USB stick, Camera, USB audio Headset/speakers etc. Also, many customers use the EHCI interface for Modem Connection. If you connect a camera to this port, you can browse the pics on the SD card in camera in the gallery using the PTP daemon in ICS. Also, you can connect USB Headset or speakers and play audio over USB."

"On Blaze if you plug in a USB audio device, all audio will be routed to the device."

"[64GB + 64GB] #GalaxySIII includes an USB driver named "snd-usb-audio" [ALSA USB audio driver]. Only testing will tell if it means USB DAC are supported out of the box." [Supercurio]

"The Samsung Galaxy S III: AndroidNZ goes hands-on, brings you our thoughts and exclusive details
...and what about those USB audio drivers?

Anyone with a passing familiarity with me will know this was one of the questions I most wanted an answer to. You see Supercurio was able to ascertain that USB audio drivers are present on the S3, only there was no way for him to know whether they work out of the box.

Sadly it seems they do not.
To my great disappointment there was no audio output on connecting my FiiO E17 USB DAC and headphone amplifier. I guess we'll just have to keep waiting for some enterprising developer to make use of those orphaned drivers that are just sitting there on the S3..."

Keep lobbying for the Android USB audio standardisation (i.e. USB DAC as a standard USB device, like a USB mass storage device, for Android smartphone/tablet).

Oh yeah! Wrote about my experience with the E7 here:

AndroidNZ: Galaxy S III: USB audio, is it really working?

Lets just say I'm happy and will post up some video the blogs YouTube channel shortly...

This vaults the S III to being the only phone for truly serious audio-lovers who want to use an Android device as their portable music player...

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."

Aww, you posted my pics

That set up is amazing, really mind blowing sound I'm getting on that.

darkestred · Aug 23, 2012

I always wanted a DAC to go with my portable music...these pictures aren't helping. How is the signature on the pico with the s3? Warm?

Using the 4 in 1 connection kit would allow you to charge the phone while using this setup right? I'm looking to (when I get a Note 2) have a setup in the car where it'll charge the phone, send the digital audio to an external DAC and from there have it go to my aux plug in the car. I'd like the convenience of only plugging in one thing instead of two once I get in the car and obviously the added audio quality.
