Cmedia 6571 codecs are intel 8051 based codecs and have firmware on them to
handle the usb protocol, i have another usb codecs which are plantronics,
they have no problem when i use them 8khz and 8 bit, but when i use them as
16 bit and 48khz, the bandwidth problem occurs again.

[1], if it's possible to sync two USB sound devices. My professional
