I'm using Studio One Artist and a StudioLive 16R. I'm new to both. I used the "StudioLive 16r Session" under "interfaces" as a new song template. Studio One is configured with a Digital Return on AVB channels 17 and 18, as indicated in documentation, and inside Studio One the Digital Return output meter shows a signal. I've also checked Universal Control's Digital Patching and Digital Return is set to Network (for AVB). In UC, the "Dig Ret" fader config shows network channels 17 and 18 for L/R. In macOS' Audio Midi Setup tool, the StudioLive 16R shows up (64 in/64 out) and the speakers show channels 17 and 18 as outputs as well.
Yet I get no output in the 16R through the headphone jack nor through the mix 1 1/4" jack. I also see no signal on Dig Ret inside UC.
What am I missing?
