Not much safe hints from my side, just guessing, but your android link related CM106
is sound/usb/quirks.c in normal/rpi linux kernel and enabled by CONFIG_SND_USB in the
linux kernel config (not enabled by the default buildroot rpi kernel config)...
After enabling this option, take a look at dmesg output and search for USB Sound Device
or try 'aplay -L' for listing all possible/found alsa sound devices...
