[LAU] Behringer UMC1820 experiences and sync settings?

[Winfried Ritsch]

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 ?
