I finally got USB Audio Recorder Pro working on my Note II again. A VERY pleasant discovery is that UARP has hardware control over the volume control of the HRT Microstreamer. What this means is that there isn't the hiss that I get using the MS on the Note II without UARP (amp is at full volume, with digital attenuation - bad!). Unfortunately, there is a clicking that occurs every few seconds that is mildly distracting.
I also decided to go from FLAC to mp3 for my portable music collection to conserve space, forgetting that UARP doesn't do mp3. DOH!
On a side note, it is too bad that something like Pandora can't be routed through UARP. I listen to it quite a bit, and the main DAC that I will be using (HifiM8) won't work with the Note II without UARP.
