Special Features Of The Digital Output; Troubleshooting - RME Audio DIGI32 PRO User Manual

11. Special Features of the Digital Output

Digital audio signals in SPDIF or AES/EBU format include the audio information and a header
(Channel Status), transfering further information. Wrong Channel Status Data lead to misfuncti-
on. The Channel Status from the input of the DIGI32 PRO is not used, instead a completely
new header for the output signal is created.
G
It is to be noted that an indication of used emphasis disappears in recording or monitor mode.
Recordings done with emphasis should always be played back setting the emphasis bit.
This can be done by activating 'Emphasis' in the settings dialog box. Changing this setting is
possible without stopping playback, and can be monitored at the analog output.
The outgoing status data of the DIGI32 PRO has, with regard to other digital appliances,
been optimized to the largest compatibility possible:
• 32 kHz, 44,1 kHz, 48 kHz according to the sample frequency
• Audio use
• No copyright, copy permitted
• Format Consumer or Professional
• Category General, generation not indicated
• 2-Channel, No emphasis or 50/15 µs
• Aux bits audio use
G
Most consumer products with optical or cinch inputs (SPDIF) accept only signals with 'Consu-
mer' indication!

12. Troubleshooting

In case the message box 'New Hardware Component found' does not appear, or the driver can´t
be installed under NT:
• Is the Error LED of the DIGI32 PRO lit when no cable is connected to the optical input?
If not, the card is either defect or not sitting properly in the slot.
When the card and the driver have been properly installed but no playback is possible:
• Check that the DIGI32 PRO appears correctly in the Device Manager.
• If the device DIGI32 PRO is marked with a yellow exclamation mark then either an ad-
dress conflict or an IRQ conflict is present.
• If no yellow exclamation mark is present check the registercard 'Resources'. For example if
the BIOS allocates a different IRQ for the PCI slot of the DIGI32 PRO as before while
Plug & Play is disabled, Windows reports an unknown configuration. This can be corrected
by activating 'Use automatic settings'.
• Check that the DIGI32 PRO has been set as 'transmitting device' in the software. Also
check the settings under >Settings/Control Panel/Multimedia/Advanced<. Here the DIGI32
PRO must appear as an audio device when it´s been correctly installed and can be set as
the preferred device under 'Audio'.
