20. Hotline – Troubleshooting
The unit and drivers have been installed correctly, but playback does not work:
•
Is Babyface Pro listed in the System Profiler? (Vendor ID 2613).
•
Has Babyface Pro been selected as current playback device in the audio application?
The 8 ADAT channels don’t seem to work
•
The optical output has been switched to 'SPDIF' format. In TotalMix FX all channels and their
assignments still exist, but the optical transmitter is then limited to two channels. The ADAT
playback devices are still usable by routing and mixing them in TotalMix to other outputs.
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 Babyface Pro 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 application.
•
Try different cables (coaxial or 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’.
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 an error scheme.
