12. Hotline – Troubleshooting
The input signal cannot be monitored in real-time
• ASIO Direct Monitoring has not been enabled within the DAW, and/or monitoring has been
disabled globally (TotalMix Options).
The 8 ADAT channels don’t seem to work
• The optical output has been switched to SPDIF in the Settings dialog.
Playback works, but record doesn’t
• Check that there is a valid signal at the input. If so, the current sample frequency is dis-
played in the Settings dialog.
• Check whether the Digiface USB has been selected as recording device in the audio appli-
cation.
• Check whether the sample frequency set in the audio application (‘Recording properties’ or
similar) matches the input signal.
• Check that cables/devices have not been connected in a closed loop. If so, set the system’s
clock mode to Master.
Crackle during record or playback
• Increase the number and size of buffers in the ‘Settings’ dialog or in the application.
• Try different cables (optical) to rule out any defects here.
• Check that cables/devices have not been connected in a closed loop. If so, set the system’s
clock mode to ‘Master’.
• Check the Settings dialog for displayed Errors.
Driver installation and Settings dialog/TotalMix work, but a playback or record is not possible
• While recognition and control of the device are low bandwidth applications, playback/record
needs the full USB transmission performance. Therefore, defective USB cables with limited
transmission bandwidth can cause such errors.
