May I ask if you use UAPP & the standard CLAS-supplied USB (OTG?) cable? The reason being is that I'm having a PITA trying to get that to work and I don't want to buy UAPP yet before ensuring this combination works reliably.
The trial is simply too short (either 20 min limitation or play tracks limitation) so I can't even evaluate the SQ coming out of UAPP as most of the time is fiddling to get it to work.
The maker has mentioned I can simply uninstall/reinstall to reset the trial but I'm losing patience and more detrimentally doesn't instill confidence in the product (for me at least).
