B Troubleshooting
Why does the start sound not play through the
896mk3?
The 896mk3 will only playback audio at a sampling
rate of 44.1, 48, 88.2 or 96 kHz.
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. If that fixes
the problem, visit motu.com to download the very
latest drivers and then install them.
‘New hardware detected’ window
If you connect your 896mk3 before running the
MOTU Audio installer, Windows will prompt you
that new hardware has been detected. Cancel this,
and run the 896mk3 Software Installer, rather than
allowing Windows to locate the drivers.
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 “Making sync
connections” on page 28 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 due to hard drive problems
If you have checked your clock settings and you are
still getting clicks and pops in your audio, you may
have a drive related problem. Set your Master
Clock Source to Internal and try recording just
using the analog inputs and outputs of the 896mk3.
If you encounter the same artifacts you may want
try using another drive in your computer. Clicks
and pops can also occur when the drive is severely
fragmented or there are other drive-related issues.
If you are using a FireWire drive on the same bus as
the 896mk3, it could be that the FireWire bus is
overloaded (too many devices on the same bus).
Try removing all devices except the 896mk3.
Connecting or powering gear during operation
It is not recommended that you connect/
disconnect, or power on/off devices connected to
the 896mk3 while recording or playing back audio.
Doing so may cause a brief glitch in the audio.
896mk3 inputs and outputs are not available in
host audio software
Make sure that the inputs and outputs are enabled.
See “Working with 896mk3 inputs and outputs” on
page 62.
No optical inputs or outputs are available in host
audio application
Check to make sure you have the desired optical
inputs and/or outputs enabled in the MOTU Audio
Console.
Monitoring - How to monitor inputs?
Please refer to the documentation for the audio
application that you are using. If your application
does not support input monitoring, you will need
to use the 896mk3’s hardware-based CueMix FX
monitoring feature. Please see chapter 8,
“Reducing Monitoring Latency” (page 65).
Controlling monitoring latency
See chapter 8, “Reducing Monitoring Latency”
(page 65).
