M-Audio Delta DiO 2496 [22/24] Possible cause

Problem: No Sound.

Possible Cause 1: There is a resource conflict with another device in

your computer. Check the Delta DiO 2496 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 Delta DiO drivers are not properly installed or

are not selected as the current audio output device.

Possible Cause 3: Misrouted outputs in the Delta Control Panel.

Check the Patchbay/Router page of the control panel software to be sure the output

you are intending to use is connected to the desired audio source. Also make sure

that if the output is routed from the digital mixer, that the faders are set for proper

signal levels 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.

Possible Cause 1: Wrong S/PDIF input (coaxial or optical) is selected

in the Delta Control Panel software.

Possible Cause 2: The Delta DiO input(s) are not properly selected in

the user’s application software.

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 Delta DiO 2496.

Possible Cause 1: The Delta DiO 2496 Audio driver is not properly

installed. Install/reinstall all Delta DiO 2496 audio drivers (see Windows Software

section).

Possible Cause 2: You have not selected the Delta DiO audio driver

from your application. Many third-party applications require you to select a specif-

ic driver (because there can be more than one in an advanced system) for use with

the application. Select the input device named "Delta DiO S/PDIF In" and/or "Delta

DiO Monitor Mixer" as your active audio driver. The manner in which this selec-

tion is made is dependent on the application (each one is a little different).
