DirectStream DAC Mk 2

Running version 2.6.2. Trying to AES/EBU connect Music Server (MS) to DAC XLR input. The Mk 2 doesn’t “see” the MS. In the menu: “Auto Input” then " Audio Power" I only see the existing USB and I2S inputs for selection. Changed out cable, same result. Any ideas?

try just cycling through the inputs. Or just hit the AES button on the remote
