My laptop is currently out of commission, awaiting a new heat-sink fan, so I tried to use my phone and its OTG cable to go into the XDA-2 but it does not work (some sound comes but it is incredibly distorted and piecemeal.) Not the end of the world, but I'm curious to know why this happens. Is it a drivers issue?
I think what's happening is the dac is taking too much amperage from the phone and that's why it comes out distorted. I tested a Xonar U3 with an android phone and a Nexus 7 V.2 and some comes out distorted and and crackling.
I've just purchased a HRT Microstreamer and it's meant to take less draw from the phone.
Don't believe it's a driver or software interface issue as I purchased USB Audio Player in the app store and it still crackles despite whatever buffer settings or error implementation. More of a hardware issue.
Someone else will be able to clarify it better than me perhaps as I don't have much experience with this.
