Hey, I just did a firmware update on the Rose 150b to version 5.2.01 and now no analogue output. Digital works. Turns out after the firmware update the preout settings need to be turned on, which I initially overlooked.
Are you using the EA version rather than the official version?
The EA version is currently in development.
Please use the official version.
