"trial-and-error" until proper operation is achieved.
CONSUMER FORMAT ADVANCED SETTINGS (Emphasis): This status
bit is used to indicate if pre-emphasis has been applied to the outgoing
digital audio signal. The default is "None" and rarely will any user want to
set the value to "50/15uSec" unless the transmitted audio has been encoded
with 50/15uSec pre-emphasis.
PROFESSIONAL FORMAT ADVANCED SETTINGS (Data Type): The user
may assign the outgoing data as audio or non-audio data. Many devices
ignore this setting. The obvious default is "audio," however, choosing “non-

surround sound) out of the S/PDIF output. Some software DVD players are
capable of this, as well as AC3 or Dolby Digital encoding software.

may choose to indicate or not indicate if pre-emphasis has been applied to
the outgoing digital audio signal. The default is "None" and rarely will any
user want to set the value to "CCITT" or "50/15uSec" unless the transmitted
audio has been encoded with one of those types of pre-emphasis.
