Merlin

I have a Motorola droid force z. Android 6.0.1. Trying to use fiio K1. Neither of the 3 options work. Shows the DAC listed. Little static at first, looks like it's playing. Got it to work a couple times by unplugging and changing settings, I think direct was the mode. Sounded great lol but can't get it go work anymore... Willing to buy a better DAC if it will work.
