Thanks for all the hard work. Any progress on outputting to another music player?
How about using a slim USB battery connected to the S3 thru a Y-cable or a small powered USB hub?
The Galaxy is a fully compliaint USB host and can supply 500 mA (though not for long). It isn't the power that makes me suggest trying the hub though a self powered USB hub would be a better choice. A "Y-connector" is unlikely to be of any value.

Im pretty sure, according to one of the usb enumeration document posted on this thread, because the s3 doesn't have a fully compliant powered usb port then anything that draws over 100ma will not enumerate or be recognised. edit link

Like you and Coop I thought that the issue might be related to power.
So what would the reason be? Will the hub take non-compliant data and somehow make it "more compliant"? Sounds like voodoo to me but perhaps someone here has a better sense of how this might work.
This is why I asked HRT in the first place. The S3 outputs a max power of 96ma/interface so it shouldn't really work at all (right?). But, the S3 does allow the MicroStreamer to render 16/44.1 files over USB (played from Neutron) but does not permit 24/96 from USB AR-PRO. I can't pretend to have the faintest grasp of this material so what am I missing here?
The native USB audio of the Samsung Galaxy S3 can’t drive the FiiO E17, the USB audio Recorder PRO running on the Galaxy S3 can, the native USB audio of the HTC One can:

. 1st USB trace capturing USB packets exchanging between a Galaxy S3 using USB Audio Recorder PRO and a HRT microStreamer
. 2nd USB trace capturing USB packets exchanging between a Galaxy S3 using native USB audio and a HRT microStreamer
It should be ideal if HRT and you forward to the USB Audio Recorder PRO development team the two mentioned USB traces as well as the USB descriptors of the HRT microStreamer and the USB Audio Recorder PRO log trace.
