M-AUDIO Delta DiO 2496 - Manual (Page 22)

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).
