The unit and drivers have been installed correctly, but playback does not work:
• Is MADIface USB listed in the System Report, USB?
• Has MADIface been selected as current playback device in the audio application?
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 MADIface USB has been selected as recording device in the audio ap-
plication.
• 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'.
Possible causes for a MADIface not working
•
The USB cable is not, or not correctly inserted into the socket
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.
