@alisynthesis Its' an RME RayDAT, when I select the ALSA interface Reaper shows errors about being unable to open the input (presumably because #Pipewire has already grabbed it). I can access it under ALSA by manually typing 'pipewire' in the driver selection in #Reaper but then I only get 2 i/o (out of 32) showing in QPWEGraph and the same gronky aliased noise with buffers <1024
