Please explain about your experiences which made you be unreliable and 
feel instability to your system so that the others such as me can get them.

In the beginning of packet streaming, your unit transfers packets with 
invalid CIP header, as shown. But enough later it starts to transfer the 
packet correctly. The above message is irrelevant to your issue.

ALSA fireworks driver adds no control element set in Linux system. This 
is a design not to bring complexity into kernel stuffs. For control 
feature to DSP on your unit, please use 'hinawa-fireworks-cui' in 
'hinawa-utils'[1] with 'libhinawa'[2], or ffado-dbus-server/ffado-mixer[3].
