M-AUDIO Delta TDIF - Manual (Page 53)

Troubleshooting Tips for Frequently Asked
Questions
Problem: No Sound.
Possible Cause 1: The Delta TDIF 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
TDIF and another device in your computer. Check the Delta TDIF
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 TDIF 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 TDIF 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
TDIF connector is connected to an external digital audio device capable of
receiving TDIF. If using the S/PDIF input, make sure that you have
selected S/PDIF instead of Analog as your input source.
Problem: No visual activity on Audio Input volume (VU) meters of

Possible Cause 2: If the software is recording from the Delta
TDIF’s monitor mixer device, be sure that the mixer’s faders, solo and
mute controls are set up properly.
