Troubleshooting Tips for Frequently Asked
Questions
Problem: No Sound.
Possible Cause 1: There is a resource conflict with another device in
your computer. Check the DiO 2448 configuration (Address, IRQ) against
those of the other devices on your computer. If necessary, change the
settings for the one or more of the devices
Possible Cause 2: The DiO 2448 drivers are not properly installed or
the DiO 2448 is not selected as the current audio output device.
Possible Cause 3: Misrouted outputs in the DiO 2448 Control Panel.
If using an S/PDIF output, verify that “SPDIF-OUT Source” is set to “WAV
(software).” If using the Analog outputs, check the WSS mixer verify the
“Volume Control” and “Wave Output” faders are set properly and not
muted.
Possible Cause 4: Improper connections of the audio accessories.
Verify that the Analog Out is properly connected to a digital mix deck or
external mixer/amplifier, or the S/PDIF Out is connected to an external
digital audio device capable of receiving S/PDIF.
Problem: No visual activity on Audio Input volume (VU) meters in your
music software.
Possible Cause 1: The DiO 2448 input is not properly selected in the

not recognizable by the DiO 2448. Open the DiO 2448 Control Panel and
click “Analyze” to analyze and configure the proper input format.
Possible Cause 3: Improper connections to audio accessories.

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.
Problem: A third party Windows digital audio program does not play or
record to/from DiO 2448.

Install (or reinstall) all DiO 2448 audio drivers (see “Windows 95/98 Driver
Software Installation” section).
Possible Cause 2: You have not selected the DiO 2448 audio driver
from your application. Many third-party applications require you to select a
specific driver (because there can be more than one in an advanced system)
for use with the application. Verify that you have selected the devices
