Multicard Operation
OS X supports more than one audio device. Since 10.4 (Tiger) Core Audio offers the function
Aggregate Devices, which allows to combine several devices into one, so that a multi-device
operation is possible with any software.
The Hammerfall DSP driver adds a number to each unit, so they are fully accessible in any
multicard-capable software.

The 8 ADAT channels don’t seem to work
• The optical output 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.
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 3FC5).
• Has Hammerfall DSP been selected as current playback device in the audio application?
