  Did anyone try the Stoner Acoustics UD110V2 with the Samsung Galaxy S4? with no need for either UAPP/UARP
 
On the https://docs.google.com/file/d/0B3XYy1FuzDUeRHQwMjBJQ0VqSjg/edit , I found that it mentioned without the need for either UAPP or UARP.
 
Can I connect it directly to the S4 (OTG)? (directly or via battery fed Y cable)
 
Please advice
 
Thanks

 
Usually if you stream through an external DAC without the aide of any specific apps like UAPP it will work but be limited to 16/48, which is really all that you need.

Thanks
 
But my question was in particular about the UD110v2 and the S4.
Are those compatible?

According to Stoner Accoustics it should work. Try sending them an email.

I too mailed Stoner Acoustics ahead of purchasing the UD110v2 to use with my Moto G to inquire about 3rd party apps. In response (February 2014) he mentions that as long as the phone supports UAC1.0 then the DAC will work in a plug and play manner (none of this attach the DAC first then re-boot the phone type shenanigans), and that the DAC has been tested with the S3, Note 2 and Note 3.
 
When I plug the DAC into the Moto G, I only get audio (music, video, games & other media) out of the DAC, all notifications etc from the phones speaker, however the only portable headphone amp I have (Fiio E5) exhibits clipping/distortion, and I am unable to attenuate the audio output from the phone at source (on the Moto G) when I plug and play. I don't know why the signal is too hot for the Fiio E5 amp - if I route audio to my hi-fi from the Moto G using the UD110, there's no clipping. I don't have access to another headphone amp to verify if it's just an issue pertaining to the E5's input, or what (as ever folks please feel free to offer your opinions/knowledge as to why this is the case). I suspect it's an impedance issue...
 
If I attach the DAC, then reboot the phone, I can attenuate the system audio (music, video, games & other media) using the Moto G's hardware buttons or Android systems volume control settings, thus no clipping/distortion. However, then all Android audio comes through the USB connected DAC until you reboot the phone with the DAC unattached, so the phone can't be used in a conventional sense as a phone with the USB DAC connected in the reboot with DAC attached manner (I never tested to see if the phones mic was disabled, but I know the earpiece certainly doesn't work).

Any of you guys in the US and have one of these to sell?

Will buy it for $10 because the cheapest one I see on eBay is $15-20 let me know!!!

It's meant to be this way. I had a moto g and now have an htc m8 and both play media/audio through the dac and notifications are sent to the speaker. This is especially true when you are using USB Audio Player PRO and preferable IMO. Volume, in my case, must be controlled through USB Audio player pro in software mode otherwise the sound is way too loud.
 
If you are interested in only music get USB Audio Player pro and use software volume control and it should hopefully get rid of the clipping. As far as other sounds, I am unsure as output with a USB Dac is extremely loud to begin with. Could be an impedance issue as you say. I've owned a Fiio E5 before and was disappointed with it so I can't really tell you for certain if that's the case. It wouldn't surprise me though if the fiio just can't handle the output volume.

If you're looking for a good FiiO portable the E5 is not something to consider, the E12 on the other hand is very good.

I've kind of got used to using the reboot with DAC attached method. At least for when I want to listen to music, UAPP is great but I like to use Spotify and Google Play aswell, and for now it's just easier to reboot with the DAC attached to live without the clipping and be able to hop from one app to the other (boundless musical delights). Have every intention of upgrading my amp (eventually) so that should hopefully put paid to the clipping and resolve the need to reboot into (and out of) "USB DAC" mode.

Yep, I'm well aware of the E12 thanks, have come this close to forking out for a Headstage Arrow 4T, and then checked myself due to financial constraints.
 
The E12 has found a lot of favour amongst head-fiers though so we'll see...

How to enable USB audio support on my Android device?
 
Plug & Play, if every USB audio-required component is functional:
 
. Required software
It depends on your Android device: native USB Audio (i.e. USB audio-enabled Android device) or eXtream USB audio (i.e. USB host-enabled Android device with the USB Audio Player PRO app available on Google Play store).
 
. Required hardware: Android device, compatible USB DAC, USB OTG cable
The Android device should be a USB On-The-Go (OTG) device, i.e. sometimes a USB host device sometimes a USB peripheral device.
The USB DAC should be a standard USB DAC compliant with PC or Mac.

A USB OTG cable is needed to connect an Android device to a standard USB DAC.

A USB OTG cable is just a USB cable with a "pin 4-connected to-pin 5" micro USB plug, so that the OTG-featured Android device can be configured to USB host mode, able to interwork with a USB peripheral like a USB DAC."

 
As it is likely that the Chuwi V88 doesn't have a native USB audio feature, you could use a free trial version of USB Audio Player PRO (UAPP) for testing:

The E12 is not a DAC...

My post was in context of an amp that swab was using.
