Why do I not get any audio signal over SPDIF at 88.2 or 96 kHz?
Older Nucleus 1 USB macOS drivers are not currently capable of 88.2 or 96 kHz sample rate operation when using SPDIF.
Please update to the latest driver for 96k SPDIF operation.
Please note that this does not affect the analogue I/O which works up to 192 kHz.
It is also only limited to macOS.
The Windows driver can use SPDIF at sample rates of 44.1 to 96 kHz.
