Tablet [Q] Nexus 7 (2012) Timur's USB ROM - DAC / audio question

Hi there,

I've searched but haven't been able to find an answear. To get the audio out from a Nexus 7 (2012) with Timur's USB ROM I need a DAC. But I can just find DAC's with one set of RCA and I need two. Can I use two DAC's from the USB-hub?

Thanks in advance.
