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’.
•
Increase the buffer size of the hard disk cache.
•
Activate Busmaster mode for the hard disks.
•
In case of a recently done BIOS update of the motherboard: Propably 'Load BIOS Defaults'
was loaded instead of 'Load Setup Defaults'. This sets the 'PCI Latency Timer' to 0 (default:
32).
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. This is
no issue when using dual CPU systems.
20.2 Installation
More information on installation problems (which fortunately are very seldom, thanks to Plug
and Play), can be found in the Tech Info 'Installation problems'. It is located in the directory
\rmeaudio.web\techinfo
on the RME Driver CD.
HDSP MADI is normally found in the Device Manager (>Settings/Control Panel/System<),
category 'Sound-, Video- and Gamecontroller'. A double click on ' Hammerfall DSP MADI'
starts the properties dialog. Choosing 'Resources' shows Interrupt and Memory Range.
The newest information on hardware problems can always be found on our website
www.rme-

, section FAQ, Hardware Alert: about incompatible hardware.
The dialog 'New hardware component found’ does not appear:
•
Check whether the PCI interface is correctly inserted in the PCI 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 worth checking the ‘Resources’ tab
anyway.
•
Check whether the Hammerfall DSP has been selected as current ASIO device.
