The Spotify app can’t use the USB audio function which is included in the USB Audio Recorder PRO app.

Like a modified Neutron Music Player, a modified Spotify app interfacing with the upcoming USB audio service developed by eXtream Software Development could output a digital audio stream to a FiiO E17 USB DAC/amp:

"If some generalized audio output API is provided by developer of USB Audio Recorder Pro then it would be great and Neutron would support it as one of additional output drivers. In the future it also worth trying to develop own USB soft-driver too."

Thanks for the quick response. The information you compiled in this thread is really helpful. Guess I'll have to get a stoner acoustic UD100 soon cuz the DAC in US version gs3 really sucks coming from iphone 4s, and there is still no word on the release date for fiio e18 or e19. gs4 is half a year away...

Would usb audio pro in this case become the player? Or just another process running in the background ?

As far as I understand, another app like Neutron Music Player using the USB Audio Android Service provided by eXtream Software Development is the player.
This USB Audio Android Service should run in the background.

"A Service is a component which runs in the background, without interacting with the user. Every developer can create new Services in his application.

Heya fellow headfiers,

I have been following this thread from a very early stage, and i really have to appreciate what Danba has made possible for us here. I have a question from you, with the amount of Dac's/Amp's said to be working with the GSIII (in particular) and other android devices it has gotten a bit confusing for me as to which Dac/Amp to purchase for my GSIII and atrios MG7's, I might get the HE 400 in a month or so. I like the Ibasso's but its huge selection , and the Fiio E17(iv heard it sounds good with the HE 400). What would you suggest a good dac/amp is under 200$ with more emphasis on the Dac aspect and where to get a usb OTG cable for it? Thank you.

Regards,

I've tried searching this thread but couldn't find the info on the following but would it be correct that for the Galaxy S3 if :-

1) non-OTG cable is used with something like the VentureCraft Go-DAP X, it's USB Audio-enabled Android mode
- the VentureCraft Go-DAP X won't be draining or siphoning the battery off the Galaxy S3
2) OTG cable is used then it's USB Host-enabled Android mode
- the USB DAC/Amp will be draining or siphoning the battery off the Galaxy S3?

Apologies if this is a silly question.

Hey there.

I can recommend the iBasso D-zero (109$) as I've done previously in this thread. That is if you want a dac/amp for portable use. The D-zero comes with a short OTG cable (even though this isn't listed on their site) as well with a short 3.5mm male to male cable, and of course the normal usb to mini usb for charging/using via a computer.

The D-zero is one of (if not the) smallest usb/dac combos out there. It packs a lot of punch for its size and you won't be disappointed with the sound.

I spoke to eXtream Software Development they and the dev of Neutron Player, are looking into this. They are looking to see how feasible it is to implement reliably.

Thats all for now though.

According to wikipedia, is impossible to have a micro b to mini b usb cable.
Have a look:

I am currently using Fiio E17 with mi SGS3 and it has an option to "disable" usb charging .... this is useful to avoid battery draining from SGS3 ! I don't know about the other dac/amp if they can do like this !
good luck

The Leckerton MK2 can do this as well, and works with the SGS3
