Those pesky RFI interference.....so far I've found changing my network setting to "WCDMA Only" mode for network setting works best as in I get the least noise when I'm out and about.....maybe you guys should try it and report back. I hope that helps.
Android phones and USB DACs - Page 181
Gear mentioned in this thread:
We have no WCDMA standard in my country at all, so this is not a solution for me.
DanBa, thanks for a detailed reply!
But I am now totally confused, and have even more questions than before.
1) USB Host and USB OTG on an android device would require the same type of cable? I.e. 4&5 pins shortened?
2) Isn't it true that in addition to supporting USB Host mode, the android device must support specific USB device types to work with them? E.g. to work with a USB DAC/Sound Card out of the box, the device must support USB Audio class of devices? Because this is exactly what is shown in the picture with Sony Xperia Z and Sony portabe headphone DAC/Amp: the "Z" series support USB audio device class out of the box.
3) Does UARP add such support to Android devices which do not natively support USB Audio device class?
4) How can one figure out, whether the claimed support of USB Host functionnality is sufficient for UARP/USB DAC combo operation, by reading the device specs?

Yes, if these Android devices support full USB host and support the Android USB host API.

DanBa, thanks a lot! Tons of useful reading. But it did not save me from the first mistake already :-)
Today I bought Sony Xperia Go: I thought this is what I needed. Nice size, Android 4.1, USB Host support... only to find out I cannot install UARP JUST because it does not comply with minimum screen resolution requirements :-((((((
Pls everyone be aware, that UARP needs AT LEAST 800x480!
Will try to return it to the seller and exchange for a Sola.
I didn't know that!

Yeah... We all need to learn how to read those boring system requirements... :-)
Hi Danba. Have there been any differences in compatibility between the Exynos and Snapdragon versions of the SIII? I saw that the ALO Pan Am was listed as compatible with the SIII in USB debugging mode. Thinking that the SIII was more or less interchangeable with the Note II, I tried the Pan Am with my Note II but have had no luck, regardless of whether USB debugging is enabled or not. I'm assuming the people who have the Pan Am working with the SIII are using the Snapdragon variant, hence the difference.
As an aside, I can confirm the iBasso D42 works with the Note II.
Yes, there is some USB difference between a Snapdragon-based Galaxy S3 and an Exynos-based Galaxy S3: the HeadAmp Pico USB DAC was only able to work with a Snapdragon-based Galaxy S3 before the fix by HeadAmp.

It’s the case so far.
By the way, can the ALO Pan Am work with the Galaxy Note2 using USB Audio Recorder PRO?
anyone tried usb audio through xperia SP??
Also, if anyone knows, does it need micro-A or micro-B otg?
By Danba's gracious posts and threads i have figured out that it must be micro-B while am sure that Xperia S has micro-A or micro-AB port which in case of xperia SP is different.
Anywho, i have ordered otg cable from ebay, though the pin looks like micro-B but am not sure though. As soon as i get it, i 'll post here.
kudos to danba for everything he did for this commmunity. (The amount of work and deliberation i could only think, from head-fi to sony websites to xda all i could find is his awesome posts everywhere, almost every website that i went through for usb audio)
Thank you very much Daniel
Alas I got the cable. So, Xperia SP stock rom 4.1.2+ stock player (no USBARP) +E7 works;-)
Thanks again danba

Jared, could you please provide a link to the cable you purchased? I have Xperia TL, bought an alleged host USB, OTG cable. Could not get it to work with my Audio GD NFB12 in either debugging mode or with USB audio recorder Pro. Figured it is a bogus cable, hopefully not a problem with the Xperia and NFB12 combo. Thanks, satwilson

The Google issue 24614 "Add support for USB Audio" has been switched from "Reviewed" to "Assigned".
But still "Priority-Medium" and no owner.
Did some further testing and it appears that the Note II does need UARP to work with the Pan Am.
Also, tried out UARP with my Note II hooked up to my Resonessence Concero and it does appear to work.
