UAPP works fine, as long as I use the "force 44100Hz" feature. The IFI is not a DAC, it only converts the signal from the phone to Fibre (light). DSP and DAC is in the MOSCONI.

A little more information about my setup. The car is a Tesla, so one reason for wanting the STD media player apps (Spotify & Walkman) is that when phone is connected by BT and USB, Teslas own UI works at the same time (through BT) as sound signal is going through the OTG. This feature unfortunately doesn't work with the UAPP, which is kind of crappy in a car like this.....

We have tested it with an Iphone and it works perfect, but I'm not an Iphone fan and it breaks my heart that it doesnt work with Z3.

Thank you for good feedback! I'll spend teh evening on Head-Fi reading up on the link from Rodrigues.
WOW, a Tesla. I'm a car guy and I rate it at the top of my list. In fact I used to work a mile away in Silicon Valley. One of my vendors was across the street. Because I was already in industrial motor controls and an ex car racer I thought I would be a good fit and applied for a job through an ex-coworker friend over there. Well he got laid off first. Then before a second interview something bizarre happened and just as well. I got a retirement package and retired to Florida. But I've followed Tesla since day one.

Back on topic, you're correct about the USB connection. I've emailed UAPP in the past and got a good response. They might have some insight.

Me too have applied for a job at Tesla, but I'm halfway around the globe and I sent a sort of General Application saying I'm willing to bring my family to California for a few years and work for Tesla... No answer yet though...

Yes it's an awesome ride, although the factory sound wasn't really what I expected. Now I'm pretty much done with the HW setup, but the source issue remains.....

The more I think about it I start to quesstion why Mosconi limit themselves to 44.1kHz input? Seems strange these days, and the amp is brand new. It was just released about a month ago.....

I'm seeing some Galaxy S5's in here with successful audio-through-usb setups. How do I get this to work on my S5? I purchased USB Audio Player PRO and I have a OTG cable however when I start the app I get the error message that says "Android did not find any devices". If I hit PLAY on the app it says "NO USB Audio Device found". My question is does this have to have a USB DAC connected as well? What I have is this, this piece is a Sony aux input device which connects to their car stereo head units, it has 2 audio inputs and one USB. My thoughts was to get the audio from my S5 to run via usb then I can just cable into the port on this device.

I use the OTG in my car, connecting through an IFI micro ILink -> Car amplifier (Mosconi D2 80.6 DSP). It seems that Car amplifier only accepts 16Bit/44100Hz, and the Z3 upsamples all tracks from Spotify or internal Walkman app to 192kHZ? I have asked Sony for the ability to remove this upsampling, but I do not expect any change...
This upsampling is weird.
Usually the current Android media player framework does a 44.1kHz to 48kHz resampling.

Could you test your setup with some free music player like BubbleUPnP?

1. Test the Galaxy S5 with a USB OTG cable and a simpler USB peripheral like a USB mouse or a USB keyboard:
Galaxy S5 >> USB OTG cable >> USB mouse

2. Test the complete setup:
music file >> UAPP running on Galaxy S5 >> USB OTG cable >> Sony XA-300 USB DAC >> car stereo amp >> car speakers

"Important: connect your device [XA-300 to S5] BEFORE starting the [UAPP] app, otherwise it will not get detected!"

The Sony Experia Z3 is the best but even with it's lower new price might not be "reasonable" to some.

USB Player Pro works fine, as I can force 44100Hz, but I use Spotify quite a lot, and would really appretiate this app being available through OTG.
That's news to me unless you have Lollipop installed, which indeed [Sony's version of it] will do the upsampling thing. On Kit Kat every file is a throughput with any apps that don't perform upsampling itself, like Onkyo HF player.
I certainly won't update my Z3 to Lollipop, the phone is a perfect media player without it, with flawless USB OTG functions.

I must have missed something. Does this 'Lollipop' issue effect the audio output of other makes/models of phones?

I've read several complaints on various phone brands and models that Lollipop messed up the USB OTG function, especially those that previously bypassed Android framework, [Sony, Samsung HTC] . Even on my Nexus 10 tablet while I got USB audio for the first time, the tablet keep generating some kind of log report to be uploaded every time I connect a USB DAC. There is a similar thread over at Head Fi [also opened by Dan Ba] where you can find what I'm talking about.
