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).
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 AVB 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.
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.
