Not, not like a smartdevice, the features of ALPEN/DAC is decided by hardware but not firmware. the problem maybe the power supply. will see what happen when we get a S III.

I see, yes, it is cheap when the quantity is huge. the question is there are so many kinds of Android Phone can only few list to buy a DAC to pair with it. anyway, we will see how can we solve the problem if someone like to bundle a DAC with their 

 

phone. sometimes I think magnet is a good option , but it may damage the BANK CARD or other ID card.

Well then I would focus on phones that you have proof it works on? 

 

I think I should make a proper list here of phones and roms/kernels that support it. It would certainly help you out.

Thanks, that is why we want to do too. I guess some Android phone, like GALAXY note, will support usd audio output when it upgrade to Android 4.0 system because it support USB OTG which means it already includes the necessary hardware .

I tried with an externally powered hub too, still no go.

Good news! Reporting back from a Galaxy Nexus (CM9|Glados 1.34)....

MX1GN.png
 

Using the UsbAudioTestRoot app, it has been successfully opened routing of microphone input to output at MX1 (I got it working at 44.1 and 48KHz at least, the interface is apparently originally designed for tablets so it didn't work out nicely)

Now we'll just have to have our fingers crossed for audio routing... smily_headphones1.gif

And which I think most USB DACs with adaptive transfer protocol should work at this point (For the reported PCM270X at SIII and TE7022L receiver in my test)

With all that possibilities, it shouldn't be long for USB DACs to be fully utilized on USB OTG enabled android devices.... and I'll be eager to see more and have the possibilities to test DACs designed for android devices soon!biggrin.gif

The App's Description says:

Simple app that checks whether the android device can recognize and use a USB sound card. Basic functionality like audio playback, recording and looping available.
Your device needs to be rooted for this application to work.
 

Which root modification is needed for this USB/DAC setup? CM9?

I'm currently using CM9 with Glados 1.34 kernel biggrin.gif

BTW, your E7 IS working with the S III, just tested it tonight when it arrived.

Samsung Galaxy S III triggers a new era of high dimensions music 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!"

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).

Samsung Galaxy S III interworks with AMB Labs Gamma2 without external power:
 
music stored on SGS3 > SGS3 player > digital audio stream >> USB OTG cable >> USB DAC AMB Labs Gamma2 >> amp >> headphone

List of USB DACs interworking with Samsung Galaxy S III for the time being:

. AMB Labs Gamma2 with USB controller TI Burr-Brown TI PCM2707

. FiiO E7 with USB controller TI Burr-Brown TI PCM2706

. Topping TP30 with USB controller TI Burr-Brown TI PCM2704

 

 

List of USB DACs non-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."

http://www.hegel.com/hd20_qa.htm      

 

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.

Samsung Galaxy S III interworks with HifiMan Express via a powered USB hub:
 
music stored on SGS3 > SGS3 player > digital audio stream >> USB OTG cable >> powered USB hub >> USB DAC HifiMan Express >> amp >> headphone

 

 

The USB DAC HifiMan Express has a USB controller TI Burr-Brown PCM2702.
May be, every USB DAC with USB controller Burr-Brown PCM270X should interwork with the SGS3.
