USB Audio for TF700

Hi,

I've been looking for a solution to use a dedicated USB soundcard with my TF700, because the sound quality from the 3,5mm analog out isn't loud enough, the quality isn't great and I hear lots of intermittent "hiss" noises when I'm watching movies with DTS sound (whatever the video player I use).

The main problem is the loudness, since I'd like to use the tablet to watch videos i.e. in a plane.
I was thinking of an external USB soundcard like the Asus Xonar U1 or U3 to connect to the dock's USB, but I'd like to know if anyone has tried it before.
Preferably, I'd like something with a dedicated headphone amp.

I have a HiFimeDIY Sabre DAC that kind of works when I plug it in the dock, I hear sounds but with lots of popping and cracking.
Using the USB Audio Player I could make the tablet work correctly with the DAC, but that one only works for music, and their custom driver doesn't work with other apps.

Any help?


(sorry if I posted in the wrong section)

An update:

I went to a store and tried a Xonar U3 connected to a TF700+dock. Same thing as with the Sabre DAC I tried earlier.
Whenever I play something, the sound is "recognizable", but it's mostly made of popping and cracking.

It sounds the same as is I was used the Audio Player before applying the proper settings (force 1-bit, 16bit sampling, 4k buffer).
This seems to be a driver issue. I heard Samsung phones/tablets work flawlessly with most external USB DACs, so this is a real shame.
