Default [Q] FIIO and the Nexus 5

I'm pretty much a novice, but know that CM11 can run the FIIO E18 with no issues. Is there a way to make any rom do this? Or what in CM11 makes it work verses not working in the stock roms. I ask because i just updated to 4.4.3 and audio through OTG wont work. It can via apps, but then you can;t stream.

Anyhow hoping someone out here as solved this issue, allowing the FIIO DAC to play whatever app though the device.

Thanks
Rocky
