I think you should contact the developer of UAPP.
Alongside the best sound quality rendering, one of the other advantages of UAPP is that its developer can be contacted and its USB audio soft driver could be adapted to be compatible with some USB DAC.

In the meantime, we could anaIyse your Geek Out-Android device dmesg output log file,

and the USB descriptors of the Geek Out using USB View.

The analysis could be proceeded as following: compare a dmesg output issued from a successful Android device - USB DAC interworking (i.e. Nexus 5 - Aune T1 dmesg output) to a bugged dmesg output (i.e. Nexus 5 - Geek Out dmesg output).

Awesome. I'll try to get some logs this weekend.

I am having my first listen of the Geek Out 1000 with an Alpha Dog, and I am being blown away by the clarity of this little guy. Just amazing!!!!

OK, another question, maybe demonstrating my technical ignorance. I'm listening to HDTracks 24/96 download of the Grateful Dead's American Beauty.My GO 1000 has 1 white light on in the "lower" section (the one closer to the connection to the computer), and that's it. Isn't it supposed to show more lights to represent the sample rate of the track playing? Do I have something set wrong? (As an aside, the sound through the Heaven V is FABULOUS-the Dead aren't supposed to sound this good!!!).

 

[Currawong]

@doctorjazz It will show the sample rate the computer is sending out, not the track. If they are different, then your computer is re-sampling the output.

Does this mean I'm set incorrectly somewhere? Using JRiver, thought I followed the directions, but wouldn't be unlike me to have not done something somewhere I needed to do.

Hello doctorjazz
 
It seems that even though you may have selected the GO1000 as the default device on Windows, and Jriver is either sending music to the Default Device or Light Harmonic Driver (Direct Sound) [Assuming such an option is available].  So to verify this do the following
 
Playing the track on JRiver, move the pointer to the Tools icon (1) so playback info is shown.
 

 
If you see something similar to what's on "2", then your GO1000 is setup wrong in JRiver. JRiver is taking the sound and giving it to Windows (using Direct Sound) so Windows plays it back on the GO1000. So Windows will resample it to whatever is has setup on the devices properties. You can change that setting up to 24/192, but everything will be upsampling on Windows (not good option for that), and all system sounds will sound through there as well. Not good.  So Click on Playback Options 
 

 
Once on Playback Options, under Audio Device select the option Light Harmonic (ASIO) [or similar]. In this case since I don't anything connected to the PC, I will choose the internal soundcard identified as High Definition Audio Device [WASAPI] (another option to bypass windows mixer that works within Windows). 
 
So after you select the GO1000, click OK/APPLY and play something now. Move the cursor to the Tools icon again. You should see on the Output that it is using ASIO [direct connection] and your GO1000 LED should reflect whatever sampling rate you send to it.
 
 

 
hope this helps

Regarding the android compatibility:
 
I have a galaxy note 2, and like everyone else here geek out 450 did not work with my device when other USB DACs did. I posted this on the lhlabs forums detailing my problem (my DSD light was on, just like another person on here).
 
Larry responded, saying that this is definitely a firmware issue in the Geek Out and the team at lhlabs is trying to solve the problem.

Yep, mine does too. Glad to know they identified the issue and are working on it.

Just got my GO720 in the mail today and wow, I am really impressed with this DAC/AMP combo. I have listened to a couple songs on both my DT770 Pro and my HE-400 and the sound that it produced was amazing. Also, I thought that the 3D Awesomifier would be a gimmick but it works really well. Just an overall solid product. The GO likes to run really hot though so anyone know if we should be using it for hours or is there a max amount of time we should have it running.

It should be safe as long as it is in a ventilated area for heat to dissipate off of GO.

OK, it's time to accessorize my GO 1000 - even though it's not here yet!
 
When it arrives, I intend to keep it cool by running it on this heat sink:
 

 
http://www.amazon.com/gp/product/B0050MR8CG
 
Here's the heat sink, under a CEntrance DACport LX:
 

 
The DACport LX runs a lot cooler this way, and I'm sure the GO will, too.
 
In this photo, I'm also using an Anker battery pack to supply 5VDC power (up to 2 Amps), getting only data from the laptop's USB port - no noise!  I'll be doing the same with the GO 1000.
 

 

 
http://www.amazon.com/gp/product/B0031ESJ2S    (Currently out of stock at Amazon, but probably available elsewhere.)
 
For the GO, with this cable, you would also need one of these (USB Female A To USB Mini Female B 5 Pin Adapter).  Ordered.
 
-----------------------------
 
I also have this cable, but it's a lot longer:
 

 
http://www.amazon.com/gp/product/B0013LSFJI    
 
For the GO, with this cable, you would also need one of these or one of these (if you prefer black to pink) USB type B female to type A Female adapters.
 
UPDATED on 12 October 2014 - I corrected the second of two links in the previous line.  Thanks Lohb!
 
-----------------------------
 
If you like the idea of eliminating potential noise from your laptop power, but don't want to mess with applying tape to the fourth pin of one of a USB A connector, as shown above, I highly recommend getting this TeraDak Teralink U9VA PSU, that includes an awesome cable for extracting only data from one USB port and only power from another.  For only $45.00, this is a steal.  And frankly, it's a noise-free 5V PSU.  I use it to power my Resonessence Concero when I don't feel like messing with my battery packs.  It's a great desktop regulated power supply for both 9V and 5V DC.  There's an adjustment screw inside that's preset to 8.5V output for the 9V jack, but you can fine-tune it to exactly what you want.

This cable does the splitting of data and power for you - without having to put tape over the fourth pin of one connector - it's included with the TeraDak Teralink PSU.  (Worth $45 by itself, in my opinion.)
 
For the GO, with this TeraDak cable, you would also need one of these or one of these (if you prefer blue to pink) USB type B female to type A Female adapters.

nice job @zilch0md! but that kills the point of a simple portable of the GO a little bit.
I will try your heat shink idea, I love it!

Great find, I was actually just thinking about doing something like that to cool my Geek down.

Nice screen shots, should be very helpful to the OP.
 
This was also covered without screen shots in Posts 311-315.
