Reboot the DAC, then reboot the computer to make sure the USB handshake is established.
Make sure the DAC2 is in USB2.0 mode, not USB 1.1 mode.
Check your Jriver setup:
- DSP Studio-Output Encoding > None
- DSP Studio-Sample Rate-Greater than 192,000 Hz > No change
- Bitstreaming > Yes (DSD)
This applies to Benchmark's Wasapi driver. Bitstreaming may be different using ASIO.
