Thanks for the reply. Per this post, JameFiio states that they are not going to declare it compatible; and as usual my lack of luck raised its head. A real shame as when using the USB Audio Recorder app there was a smile; I really like the (excuse lack of proper terminology) dryness or clinical-ness that the E07k brought to the mix. The Note 2 paired with an E11 and ATH-M50 is fun enough but rather dark sounding and definitely doesn't have as many details front and centre.
As I'm based in the Middle East, meaning asking about a micro USB OTG cable is an exercise in frustration resulting in my reliance upon Amazon. I do not think the cable itself is bad; could you please leave your cable unplugged from the DAC and plug it into the Note 2 and tell me whether or not a "USB device connected" notification pops up? Because that's the behaviour exhibited by my setup. I'm also sure that the E07K is good as it pops right up on my Linux laptop.
If push comes to shove I'll attempt to upgrade the kernel to your recommendation. While I don't have any problems configuring, building and installing kernels on Linux...I just wanted a phablet that worked. Of course I want to run a DAC off it so that desire isn't set in stone. Wondering if it's worth waiting for another stock kernel update or take the plunge of rooting and installing the new kernel.
sorry for the late reply :
yes connecting the DAC triggers a "USB device connected" (or something like this, as I have the UI in french) notification ; and for your later question, there is no settings to change to let the DAC work with the Galaxy Note 2 : as soon the DAC is connected, I open Neutron media player and the sound is routed to the device (no more Note 2 speaker sound), I have nothing to do.
