When I start Ardour, for example, which employs the ALSA driver
(optionally through JACK), it is able to employ the audio interface for
a while but this will invariably and eventually result in a string of
buffer under-runs, at which point the DAW automatically disengages from
using the audio interface. Any attempt to reconnect to the interface
results in a segfault. I realise this may appear to be a fault in
Ardour itself but there are no such issues with the regular onboard
interface. If you want I can run some tests, but you'll have to guide
me through it.

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].
