The 8 ADAT channels 25-32 don’t seem to work
• The optical output ADAT4 has been switched to 'SPDIF'. 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.
• Check whether the Hammerfall DSP has been selected as recording device in the audio
application.
• 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 to rule out any defects here.
The card and drivers have been installed correctly, but playback does not work:
• Is Hammerfall DSP listed in the System Profiler/PCI? (Vendor 10EE, Device ID 3FC6).
• Has Hammerfall DSP been selected as current playback device in the audio application?
• Check that cables/devices have not been connected in a closed loop. If so, set the system’s
clock mode to ‘Master’.
