I’m just getting the Behringer UMC 1820 to run in Ubuntu Studio 18.04 out of the box!
You can change WordClockSource and muting of ADAT-Channels in AlsaMixer.

I was able to have 0.7ms latency with 96kHz.

I was also able to use the 8 optical ADAT I/O without any problems.
The only thing was to get rid of puleaudio:
I did some tests and recordings to show setup, two time monitor-mixing, ADAT and latency demo on youtube: /channel/UCINH_Fh0Ego_IWIVed3RUmA
It’s in German but you’ll get the point.
I like to use an RME 96/8 PAD on my old PC. That PCIe Card was an expensive on!
The UMC 1820 was about 180,- Euro, and now I’m able to use USB an a newer Laptop
I’m locking forward to test the Mic-Preamps against the ones build in my old Yamaha O3D.
You will hear that on my YouTube-Channel, next weeks.
