Default USB Audio not working on AOSP

I tested the following ROMs and discovered they DO NOT support USB Audio:

AICP 3/06/14
AOSB 2/26/14
Carbon 3/02/14
CM10.2 2/01/14
CM11 3/07/14
Liquidsmooth 3/05/14
PACman 3/05/14
Slimkat 2/16/14

I can confirm that USB Audio DOES work with the GPE ROM. My understanding is that the GPE ROM is built from Sense, so I haven't encountered a single non/Sense ROM that supports USB Audio.
Has anybody had any luck with AOSP and USB Audio on the VZW HTC One?
