Hello,
My experience:
I had the UMC1820 working with an Olinuxino-A64 using Armbian-buster as a
recording device under a roof outside for a year (summer/winter) under a roof
and is working great so far. [1]
alsamixer is working, but did not try to sync to external source.
The only drawback was/is, that if denbian reboots sometimes the inteface is
not recognized anymore and seems the USB-bus needs a kind of reset. After
poweroff + USB-power Off it works again.
My (urgent needed) solution: I put a relais which switch power of UMC1820 off
on reboot and on after reboot.
It seems the USB-port does not reset if power stays on, but could also be a
issue from the embedded computer.
Did anybody had such a experience ?

Hi list,
I am thinking of replacing my RME HDSP CardBus+Multiface after twenty years
because it has never been really stable (firmware doesn't load reliably,
multiface is sometimes randomly detected as digiface, random I/O box
disconnects locking up jackd, etc.). This is sad because it is such a
great card. Now I am looking for similar specs with a class compliant
USB connection. I am trying to avoid Motu and the newer RME devices
because I would pay a lot for (DSP/Mixer) features that would remain
inaccessible for me from within Linux. It seems, and hesitate to say so,
that the Behringer UMC1820 is the closest to my needs. Has many I/Os and
most if not all of its settings should be configurable from the boxes
hardware controls. The only thing I am wondering about is how I can tell
the card to be a digital clock source or follower. Is this something
that can be set with alsamixer perhaps? Does anyone have the card and
can confirm and report on its reliability perhaps?
Thanks!
Peter
