17.1 General
The newest information can always be found on our website www.rme-audio.com, section FAQ,
Latest Additions.
The input signal cannot be monitored in real-time
• ASIO Direct Monitoring has not been enabled, and/or monitoring has been disabled globally
(for example in TotalMix).
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 HDSP system 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 (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’.
Low Latency ASIO operation under Windows 2000/XP on single CPU systems:
• To use ASIO at lowest latencies under Windows 2000/XP even when only having one CPU,
the system performance has to be optimized for background tasks. Go to >Control Panel/
System/ Advanced/ Performance Options<. Change the default 'Applications' to 'Background
tasks'. The lowest usable latency will drop from 23 ms to around 3 ms.
17.2 Installation
Hammerfall DSP is found in the Device Manager (>Settings/ Control Panel/ System<), category
'Sound-, Video- and Gamecontroller'. A double click on 'Hammerfall DSP MADI' starts the prop-
erties dialog. Choosing 'Resources' shows interrupt and memory range.
The newest information on hardware problems can always be found on our website www.rme-
audio.com, section FAQ, Hardware Alert: about incompatible hardware.
The dialog 'New hardware component found’ does not appear:
• Check whether the PCI Express interface is correctly inserted in the PCI Express slot.
The card and drivers have been installed correctly, but playback does not work:
• Check whether the Hammerfall DSP appears in the Device Manager. If the ' Hammerfall
DSP’ device has a yellow exclamation mark, then there is an address or interrupt conflict.
• Even if there is no yellow exclamation mark, it is still worth checking the ‘Resources’ tab.
