Hi Rick, We are currently using a Raspberry Pi 4b 4GB with focusrite 2i2 USB audio interfaces. The audio is completely clean, the issue we are having is with latency. I've just posted a thread about it this afternoon. The setup has been proved to work with a local loopback in jack and also achieves a low latency link with jacktrip, but when using OpenOB, we are hearing around 1 second of delay. Any suggestions would be greatly appreciated, Dan
