Thanks for this information,
I think it's time to contact the manufacturer.
Do you know if I can take some relevant traces (kernel module to load, /proc/asound file to parse, anything else)? so I can detail my email to him.
Thanks.

USB DAC suddenly disappears, from dmesg I can see:

These error codes indicate that the device's firmware does not react at all. Either the firmware has locked up due to a bug, or the hardware has shut down for some reason.
