Hi,
I'm contacting you regarding a few issues with my Echo Audiofire 12. It has the latest firmware (5.8). With a recent kernel (4.15.0-22-generic) it is recognised by the OS but it works unreliably, leading to system instability.
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.
Here is the dmesg output:

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.
It is also impossible to use as a system card, and alsamixer is unable to set the volumes for the 12 channels, but here I'm probably doing something wrong. If you want to improve support for the card, I can cooperate, I have no coding skills unfor tunately.
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].
