A Troubleshooting
Why does the start sound not play through the
828x?
The 828x 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
828x software and choose only to install the
MOTU ASIO driver, not the WDM Driver. Restart
again.
‘New hardware detected’ window
If you connect your 828x before running the
MOTU Audio installer, Windows will prompt you
that new hardware has been detected. Cancel this,
and run the 828x 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 30 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 828x. 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.
Connecting or powering gear during operation
It is not recommended that you connect/
disconnect, or power on/off devices connected to
the 828x while recording or playing back audio.
Doing so may cause a brief glitch in the audio.
828x inputs and outputs are not available in host
audio software
Make sure that the inputs and outputs are enabled.
See “Working with 828x inputs and outputs” on
page 58.
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 828x’s hardware-based CueMix FX
monitoring feature. Please see chapter 8,
“Reducing Monitoring Latency” (page 61).
Controlling monitoring latency
See chapter 8, “Reducing Monitoring Latency”
(page 61).
