Why does the start sound not play through the
828mk3?
The 828mk3 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. Reinstall the
828mk3 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 828mk3 before running the
MOTU Audio installer, Windows will prompt you
that new hardware has been detected. Cancel this,
and run the 828mk3 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.
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.
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 Clock
Source to Internal and try recording just using the
analog inputs and outputs of the 828mk3. 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 828mk3, it could be that the FireWire bus is
overloaded (too many devices on the same bus).
Try removing all devices except the 828mk3.
Connecting or powering gear during operation
It is not recommended that you connect/
disconnect, or power on/off devices connected to
the 828mk3 while recording or playing back audio.
Doing so may cause a brief glitch in the audio.
828mk3 inputs and outputs are not available in
host audio software
Make sure that the inputs and outputs are enabled.
See “Working with 828mk3 inputs and outputs” on
page 57.
