ALSA BeBoB driver supports streaming functionality only, while this
model require internal multiplexer setting to generate any sounds from
its analog/digital audio ports. See:
http://subversion.ffado.org/wiki/AvcModels/DigiDesignMboxPro2

Currently I have little time to implement them into userspace control
applications such as ffado-dbus-server/ffado-mixer. Instead of them,
users can hear any sounds by setting correct parameters via
linux-firewire-utils or something.
