Apparently, the USB audio feature is enabled on factory Samsung Galaxy S III:
 
"I got my sgs3 a few hours ago and just plugged it into my Topping tp30 USB DAC/amp and it's playing audio through it to my speakers!!!"
 
 
Affordable hi-fi rig:
 
music stored on SGS3 > SGS3 player > digital audio stream >> USB cable >> USB DAC/amp Topping TP30 >> speakers

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).

Yes, it is strange.

 

A dmesg log could detail what is going on.

USB audio is enabled on factory Samsung Galaxy S III connected to a USB sound stick:

"I just tested one of those cheap PC usb audio sticks with a c-media chipset and it works fine with the SGS3 too. Here's the dmesg output when I plug it in:

Nope, I tried via an externally powered hub too as Danba had brought that to my attention. It did cause strange effects to playback speed/skipping when connected that way, based off what the progress bar was doing, but there was still no sound (so it was interfacing with the phone, after a fashion, but still not functional).

Samsung Galaxy S III interworks with USB DAC/amp FiiO E7:
 
music stored on SGS3 > SGS3 player > digital audio stream >> USB OTG cable >> USB DAC/amp FiiO E7 >> headphones
 
 
Samsung Galaxy S III triggers a new era of Hi-Fi for the masses with affordable rig:
 
. affordable (subsidized) smartphone
 
. affordable common USB DAC/amp compliant with PC or Mac, like FiiO E7 (us$80)
"Clearly, the E7 is priced very competitively, and I consider it a good product — not some cheap Chinese stuff. Not only is the E7 packed with features, it also comes with a solid build quality, and a solid sound quality as well."
 
. affordable headphones, like Digitech Pro Monitor Headphones (us$50), clone of Fischer Audio FA-003, Brainwavz HM5 or Lindy Premium Hi-Fi headphones
"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!"

List of USB DACs with known USB controller that interwork with Samsung Galaxy S III for the time being:
. AMB Labs Gamma2 with USB controller TI Burr-Brown PCM2707
. FiiO E7 with USB controller TI Burr-Brown PCM2706
. HifiMan Express with USB controller TI Burr-Brown PCM2702
. Topping TP30 with USB controller TI Burr-Brown PCM2704
 
List of USB DACs with known USB controller that don't interworking with Samsung Galaxy S III for the time being:
. FiiO E17 with USB controller Tenor TE7022
. iBasso D6 with USB controller TI TAS1020B
. Grant Fidelity TubeDAC-11 with USB controller Tenor TE7022
 
 
The USB DAC Hegel HD20 with USB controller Tenor TE7022 has also some issue with Linux-powered PC:
"I try to connect the HD20 to a computer using Linux Ubuntu. Installation seems fine but there is no sound?
On computers using the Linux Ubuntu operatating system you need to go to settings and choose which soundcard you want to use: the internal or the HD20 TE7022."
 
The USB DAC Audiotrak Prodigy Cube with USB controller Tenor TE7022 has also some issue with Linux-powered PC:
"PRODIGY CUBE supports Microsoft Windows XP, Windows Vista, Windows 7 and Mac OS X.
PRODIGY CUBE is not fully compatible with Linux, but it has been confirmed that the TE7022L chipset support.
The TE7022L chipset is TENOR's USB controller Chipset.
Please understand that we are not able to support your request for Linux because there are a wide variety of choices in Linux version and range."
 
 
USB DACs with USB controller Tenor TE7022 work perfectly with some Linux setup:
 
 
What is going on at the Android Linux kernel level, when USB DACs with USB controller Tenor TE7022 don’t interwork with Samsung Galaxy S III?
 
Dmesg log output and lsusb log output could detail what is going on.

SGS3 - FiiO E17 Full-Speed / High-Speed switching issue?
 
303340_4243507171833_1087813988_n.jpg
 
 
SGS3 USB driver issue?: some parameters are not well-adjusted?
 
538560_4243507851850_854898738_n.jpg
 
"The host controller directs traffic flow to devices, so no USB device can transfer any data on the bus without an explicit request from the host controller. In USB 2.0, the host controller polls the bus for traffic, usually in a round-robin fashion. The throughput of each USB port is determined by the slower speed of either the USB port or the USB device connected to the port."
 
 
Powered High-Speed USB 2.0 hub workaround?
 
180260_4243571933452_1200696734_n.jpg
 
"High-speed USB 2.0 hubs contain devices called transaction translators that convert between high-speed USB 2.0 buses and full and low speed buses. When a high-speed USB 2.0 hub is plugged into a high-speed USB host or hub, it will operate in high-speed mode. The USB hub will then either use one transaction translator per hub to create a full/low-speed bus that is routed to all full and low speed devices on the hub, or will use one transaction translator per port to create an isolated full/low-speed bus per port on the hub."

Audiotrak ProDigy CUBE works great under Ubuntu 12.04 and OpenSUSE 12.1, at least in Analog Output mode.

Maybe changed controller from Tenor TE7022 recently but I don't know how to check that.

 My theory of  SGS3 Full-Speed / High-Speed switching issue is wrong. 
 
The SGS3 interworks with the USB DAC ODAC using the USB controller Tenor TE7022.
 
SGS3 > digital audio stream >> USB DAC "ODAC" >> amp "O2" >> headphone
 
It's a very good news. Before, it’s rather depressive that the SGS3 can only interwork with rather old generation USB DACs using the old USB controller Burr-Brown 2xxxx.

It’s very interesting that the SGS3 can power the ODAC, which is a USB powered 24/96 DAC, without a powered USB hub.
