Cause / Remedy
• Make sure that the Digital Out setting is set to On (page 56).
• Check that the Dolby Digital, DTS and MPEG out settings
(pages 56-58) are suitable for your amplifier/receiver—check the
instruction manual that came with your amplifier/receiver.
• SACDs and some DVD-Audio discs do not output digital audio.
Listen through the player's analog audio outputs.
• This is due to differences in the audio format and is not a
malfunction.
•Make sure that Audio Output Mode is set to 5.1 Channel
(page 67).
•Check that the Dolby Digital, DTS and MPEG Out settings
(pages 56–58) are suitable for your amplifier/receiver—check the
instruction manual that came with your amplifier/receiver.
• DVD-Audio and SACDs do not output multichannel digital
audio. Listen through the player's analog outputs.
• Check that the settings in the Speaker Installation screen are
correct (page 67).
• Check the audio options available from the disc menu.
• Make sure that Linear PCM Out is set to Down Sample Off
(page 57).
• As a copy-protection measure, some DVDs do not output 96kHz
audio. In this case, even if set to Down Sample Off, the player
automatically outputs the audio at 48 kHz. This is not a malfunc-
tion.
• The player does not output digital audio from the optical/
coaxial jacks at these sampling rates. The digital output is
automatically downsampled.
• Check that Linear PCM Out is set to Down Sample Off
(page 57).
• Some discs are digital copy protected and do not output high
sampling rate digital audio. In this case the output is automati-
cally downsampled.
• If this unit is connected to a non-DTS compatible amplifier or
decoder using a digital audio cable, set DTS Out to DTS > PCM.
If you do not do this, noise will be output when you play a DTS
disc.
• If this unit is connected to a DTS-compatible amplifier or
decoder using a digital audio cable, check the amplifier settings,
and that the cable is properly connected.
