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

user’s application software.

Possible Cause 2: The DiO 2448’s S/PDIF IN format is inverted and

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.

Problem: Repetitious Sound.

Possible Cause: Wrong IRQ, or 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.

Problem: A third party Windows digital audio program does not play or

record to/from DiO 2448.

Possible Cause 1: The DiO 2448 audio driver is not properly installed.

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
