M-AUDIO Delta RBUS - Manual (Page 57)

Troubleshooting Tips for Frequently Asked
Questions
Problem: No Sound.
Possible Cause 1: The Delta R-BUS hardware or software device
drivers are not properly installed. See the installation sections of this
manual for further information.
Possible Cause 2: There is a resource conflict between the Delta
R-BUS and another device in your computer. Check the Delta R-BUS
configuration (Address, IRQ) against those of the other installed devices.
If necessary, change the settings for the one or more of the devices.
Possible Cause 3: Your application software has not been properly
configured to use the Delta R-BUS as its audio output device.
Possible Cause 4: Misrouted outputs in the Delta Control Panel.
Check the Delta Control Panel’s Patchbay/Router page to verify output
routing assignments. Also, make sure that if the output is routed from
the digital mixer, that the mixer’s faders, solo and mute controls are set
up properly.
Possible Cause 5: Improper connections of the audio accessories.
Verify that the Delta R-BUS analog audio outputs are properly connected
to a mix deck or external mixer/amplifier, that the S/PDIF Out is
connected to an external digital audio device capable of receiving
S/PDIF, or that the R-BUS connector is connected to an external digital
audio device capable of receiving R-BUS. If using the S/PDIF input,
make sure that you have selectedS/PDIF instead of Analog as your input
source.
Problem: No visual activity on Audio Input volume (VU) meters of
user software.
Possible Cause 1: The Delta R-BUS input devices are not properly
selected in the user’s application software.
Possible Cause 2: If the software is recording from the Delta
R-BUS’s monitor mixer device, be sure that the mixer’s faders, solo and
mute controls are set up properly.
Possible Cause 3: Improper connections to audio accessories.
Problem: Repetitious Sound.
Possible Cause: An IRQ resource conflict. Often this will result in
a small segment of sound (0.5 to 1 second) repeating itself over and over,
sometimes completely locking up the computer. See the general
troubleshooting suggestions at the beginning of this section.
