named “DiO-2448 Record” and “DiO-2448 Playback” as your active audio
drivers. The manner in which this selection is made is dependent on the
application (each one is a little different).
Problem: I’m getting some pops and clicks in my audio recording.
Possible Solution: Some accelerated graphics cards use excessive
amounts of system bandwidth, preventing the recording buffer of an audio
card from keeping up with demand. This can cause clicks in the recording.
Reducing or turning off the graphics acceleration feature of the graphics card
may often solve this problem. In Windows, this is accessed from Settings |
Control Panel | System | Performance | Graphics.
Problem: Audio recorded or monitored from the S/PDIF inputs is
extremely distorted and/or noisy.
Possible Cause 1: You are using more than one S/PDIF input
simultaneously. Please use only the optical or coaxial input at a time and
disconnect the opposite if attached to a live device.
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.
Problem: Can’t monitor S/PDIF in at the Analog outputs.
Possible Solution: Open the DiO 2448 Control Panel and verify that
“Monitor SPDIF-IN at ANALOG-OUT” is selected.
Problem: Can’t monitor S/PDIF in at the S/PDIF outputs.
Possible Solution: Open the DiO 2448 Control Panel and verify that
“SPDIF-OUT Source” is set to “SPDIF-IN”.
Problem: Can’t monitor CD-ROM analog audio input at S/PDIF out.
Solution: There is no hardware path that supports this operation.
Problem: Can’t record from CD-ROM analog audio input.
