Lorne, If you have any thoughts on what might have changed between Rivendell 1.7.x and 2.x.x I'd love to hear them. Our USB -> S/PDIF interfaces worked like a charm on 1.7.1 and refuses to work 2.x.x despite my sincere efforts. We use 44.1 here and I know the interface will support both. These interfaces use the Burr-Brown (TI) PCM2901 chips which are listed in the HCL.
