Performance Tips & Troubleshooting
Why does the start sound not play through the
896HD?
The 896HD will only playback audio at a sampling
rate of 44.1, 48, 88.2, 96, 176.4 or 192kHz.
The computer freezes when it starts up
If the computer is unable to boot up, it may be a
conflict with the WDM Driver. As soon as the
computer boots up, Windows will try and initialize
the WDM Driver. If this fails, your computer will
hang. To determine if the WDM Driver is the
problem, boot up in Safe Mode or remove the
MOTU Audio software with the Add/Remove
Programs Control Panel then restart. Reinstall the
896HD software and choose only to install the
MOTU FireWire ASIO driver, not the WDM
Driver. Restart again.
‘New hardware detected’ window
If you connect your 896HD before running the
896HD Software Installer CD, Windows will
prompt you that new hardware has been detected.
Cancel this, and run the 896HD Software Installer,
rather than allowing Windows to locate the drivers.
Audio in SONAR speeds up or slows down
This could be caused by having incorrect SMPTE/
MTC Sync settings when you record audio into
Sonar. These settings are located in the
Advanced
Tab in the Audio Options window, accessed from
Sonar’s Options menu. Make sure that you have the
SMPTE/MTC Sync set to “Trigger and Freewheel”
before recording audio while slaved to external
time code.
896HD inputs and outputs are not available in
SONAR
Make sure that the inputs and/or outputs that you
want to use are enabled in SONAR. Also run the
Wave Profiler in the Audio preferences dialog.
896HD inputs and outputs are not available in
Cubase
Make sure that the inputs and outputs are enabled
in Cubase.
Sound Forge and ‘Smooth Scroll’
If the Smooth Scroll option under the Options
menu is turned on, you may experience clicks and
pops or other anomalies in the audio playback.
This gets worse as you zoom in more to the
waveform while playing. For the best quality
playback, turn this option off.
No input from an ADAT
If you are having trouble recording on your ADAT
from the 896HD, check the Digital input setting.
After power cycling, tape decks often come up
configured to record from their analog inputs. You
won't be able to record from the 896HD to a tape
deck until it is switched to digital input.
Clicks and pops under word clock sync
Many problems result from incorrect word
clocking. It is essential that all digital devices in the
system be word locked. Consult chapter 4,
“Installing the 896HD Hardware” (page 17) for
detailed information on how to word clock your
gear. Whenever there is any weird noise or
distortion, suspect incorrect word lock.
Clicks and pops under ADAT Sync
Sometimes, the ADAT sync cable seems to be
plugged into the 896HD, and partially works - but
it isn’t really all the way in. This can cause clicks
when slaved to ADAT 9-pin. Make sure the cable is
seated firmly.
